NOTES 131 Scope[This section shall be divided into the following paragraphs.]1.1 Identification[This paragraph shall contain a full identification of the system and the software to which this document applies, including, as applicable, identification number(s), title(s), abbreviation(s), version number(s), and release number(s).]1.2 System Overview[This paragraph shall briefly state the purpose of the system and the software to which this document applies. It shall describe the general nature of the system and software; summarize the history of system development, operation, and maintenance; identify the project sponsor, acquirer, user, developer, and support agencies; identify current and planned operating sites; and list other relevant documents.]1.3 Document Overview[This paragraph shall summarize the purpose and contents of this document and shall describe any security or privacy considerations associated with its use.]2 Referenced Documents[This section shall list the number, title, revision, and date of all documents referenced in this specification. This section shall also identify the source for all documents.]3 Requirements Summary[This section shall be divided into the following paragraphs to describe the risk management requirements as it currently exists.]3.1 Background, Objectives, and Scope[This paragraph shall describe the background, mission or objectives, and scope of the product or situation.][Example: Requirements regarding software configuration management (SCM) cover a broad arena. SCM is considered one of the integral processes that support the other activities in the standard. The developer's approach, described in the project's SDP, is to address all applicable contract clauses for SCM including:Configuration identificationConfiguration controlConfiguration status accountingConfiguration auditsPackaging, storage, handling, and delivery3.2 Operational Policies and Constraints[This paragraph shall describe any operational policies and constraints that apply to the current system or situation.][Example: SCM activities apply to all software products prepared, modified, and/or used to develop software products as well as to the products under development, modification, reengineering, or reuse. If a system/subsystem or SWI is developed in multiple builds, SCM in each build is to be understood to take place in the context of the software products and controls in place at the start of the build.]3.3 Description of Current System or Situation[This paragraph shall provide a description of the current system or situation, identifying differences associated with different states or modes of operation (for example, regular, maintenance, training, degraded, emergency, alternative-site, wartime, peacetime). The distinction between states and modes is arbitrary. A system may be described in terms of states only, modes only, states within modes, modes within states, or any other scheme that is useful. If the system operates without states or modes, this paragraph shall so state, without the need to create artificial distinctions. ]3.4 Users or Involved Personnel[This paragraph shall describe the types of users of the system, or personnel involved in the current situation, including, as applicable, organizational structures, training/skills, responsibilities, activities, and interactions with one another.][Example: Developer's key activities related to Software configuration management:Describe the approach to be followed for software configuration management, identifying risks/uncertainties and plans for dealing with them. Cover all contractual clauses pertaining to software configuration management.Participate in selecting CSCIs during system (architectural) design. Identify entities to be placed under configuration control. Assign a project-unique identifier to each SWI and each additional entity to be placed under configuration control, including software products to be developed or used and the elements of the software development environment. Use an identification scheme that identifies entities at the level of control and include version/revision/release status.Establish and implement procedures designating levels of control each identified entity must pass through, the persons or groups with authority to authorize changes and to make changes at each level, and the steps tobe followed to request authorization for changes, process change requests, track changes, distribute changes, and maintain past versions. Propose to the acquirer, in accordance with contractually established forms and procedures, changes that affect an entity already under acquirer control. Prepare and maintain records of configuration status of all entities that have been placed under project-level or higher configuration control. Maintain configuration status records for the life of the contract. Include, as applicable, version/revision/release, changes since being placed under project-level or higher configuration control, and status of associated problem/change reports.Support acquirer-conducted configuration audits as specified in the contract.Establish and implement procedures for packaging, storage, handling, and delivery of deliverable software products. Maintain master copies of delivered software products for the duration of the contract.Prepare a version description for the system.Meet general requirements and perform integral processes of the standard.]3.4.1 Configuration Requirements[This paragraph describes the configuration management requirements for the project.][Example: SCM requirements task the developer to "keep track of" everything during the course of the development. SCM is an activity, not an organization. SCM may be performed by members of the development team, individuals within a project tasked with that responsibility, a separate organization, or other arrangement suitable for the project.]3.5 Software Configuration Management Criteria[This paragraph describes the software configuration management criteria to be followed during the project.[Example: The standard requires the developer to establish levels of control for all work products. Some examples of possible levels of control and of things the developer might identify and control are:Author control:Engineering data -- notes, records, work-in-progress (i.e., dataspecified in documents associated with particular developmentactivities)Software development filesProject control:Source code files, data files, installation softwareInformation in documents agreed upon by the project to becorrectReuse librariesEvaluation recordsOrganizational control:General purpose software -- operating systems, databasemanagement systems, e-mail, word processors, spreadsheetsEngineering and development tools -- CASE tools, editors,compilers, debuggers, SCM tools, test softwareComputer system administrative tools and products -- diagnosticsoftware, network managers, archives, backupsEvaluation recordsAcquirer control:SpecificationsSome key goals of SCM requirements are to ensure that the developer: keeps track of all software and software product descriptions associatedwith the project; implements only authorized changes to requirements; and knows what software and associated products match a specific set of requirements or changes to those requirements.To implement changes to requirements, the acquirer and developer must agree upon what those changes are. When requirements have been defined and recorded as specifications and those specifications have been placed on contract, changes are implemented through contract modifications. When specifications have not been made a part of the contract, the acquirer and developer will need to provide a means for controlling and making changes to requirements. These means can be as informal as a phone call or hand-shake, or as formal as documents signed by authorized acquirer and developer representatives. The standard does not provide contractual forms or notices concerning changes in requirements, such as Engineering Change Proposals (ECPs), Engineering Change Notices (ECNs), or notification to users of changes in a particular version of the software. Although the standard does provide a reminder in the form of two "shell" requirements to support acquirer configuration management activities for (1) proposing changes to acquirer controlled entities, and (2) supporting configuration audits, these activities may not apply to all projects.All work products (including computerized files, the software products that constitute the development environment, and hardware), not just deliverables, are to be identified and controlled during the developmentand under developer software configuration management activity. The physically controlled items can include: computer files, magnetic media (tapes, diskettes, video cassettes), paper documents, books, manuals, and drawings.The standard leaves it up to the developer to describe what software configuration management records will be produced, when they will be produced, the level of detail of information that will be contained in each record and who is responsible for performing these activities.4 Justification[This section shall be divided into the following paragraphs.]4.1 Assumptions and Constraints[This paragraph shall identify any assumptions and constraints applicable to the changes identified in this section.]4.2 Additional Items for consideration:[This paragraph shall identify additional items that should be taken into consideration.][Example: Additional items that should be taken into consideration are: Describe the approach to be followed for software product evaluation, identifying risks/uncertainties and plans for dealingwith them. Cover all contractual clauses pertaining to softwareproduct evaluation.•Perform in-process evaluations of the software products generated. Perform a final evaluation of each deliverablesoftware product before its delivery.•Prepare and maintain records of each software product evaluation. Maintain these records for the life of the contract.Handle problems in software products under project-level orhigher configuration control in accordance with paragraph 5.17of the standard.•Maintain independence in software product evaluation. The persons responsible for evaluating a software product are not tobe the same persons who developed the product.•Meet general requirements and perform integral processes of the standard.5 Notes[This section shall contain any general information that aids in understanding this document (e.g., background information, glossary, rationale). This section shall include an alphabetical listing of all acronyms, abbreviations, and their meanings as used in this document and a list of terms and definitions needed to understand this document.]。

Answer: FalseDifficulty: Moderatepanies in the same industry often select very different distribution networks, because the choice of the distribution network can be used to achieve a variety of supply chain objectives ranging from low cost to high responsiveness.Answer: TrueDifficulty: Moderate25.The main advantage of a distribution network with local storage is that it can lower the delivery cost and provide a faster response than other networks.Answer: TrueDifficulty: Moderate26.When designing supply chain networks, companies must build appropriate flexibility to help counter fluctuations in exchange rates and demand across different countries.Answer: TrueDifficulty: Moderate27.Inventory and facility costs increase as the number of facilities in a supply chain increase. Answer: TrueDifficulty: Moderate28.Transportation costs increase as the number of facilities is increased.Answer: FalseDifficulty: Moderate29.When faced with a network design decision, the goal of a manager is to design a network that minimizes the firm’s costs while satisfying customer needs in terms of demand and responsiveness.Answer: FalseDifficulty: Hard30.The supply chain network is designed to maximize total profits, taking into account the expected margin and demand in each market, various logistics and facility costs, and the taxes and tariffs at each location.Answer: TrueDifficulty: Easy31.Decisions made during the supply chain design phase regarding significant investments in the supply chain, such as the number and size of plants to build, the number of trucks to purchase or lease, and whether to build or lease warehouse space, cannot be altered in the short term. Answer: TrueDifficulty: Moderate32.Decisions made during the supply chain design phase regarding significant investments in the supply chain, such as the number and size of plants to build, the number of trucks to purchase or lease, and whether to build or lease warehouse space, rarely remain in place for several years. Answer: FalseDifficulty: Moderate33.Decisions made during the supply chain design phase regarding significant investments in the supply chain, such as the number and size of plants to build, the number of trucks to purchase or lease, and whether to build or lease warehouse space, define the boundaries within which the supply chain must compete.Answer: TrueDifficulty: Moderate34.Long-term contracts for both warehousing and transportation requirements will be more effective if the demand and price of warehousing do not change in the future or if the price of warehousing goes up.Answer: TrueDifficulty: Easy35.Long-term contracts for both warehousing and transportation requirements will be more effective if either demand or the price of warehousing drops in the future.Answer: FalseDifficulty: Moderate36.The present value of future cash flows is found by using a discount factor.Answer: TrueDifficulty: Moderate37.The rate of return k is also referred to as the present value of capital.Answer: FalseDifficulty: Easy38. A negative NPV for an option indicates that the option will lose money for the supply chain. Answer: TrueDifficulty: Moderate39.The decision with the lowest NPV will provide a supply chain with the highest financial return.Answer: FalseDifficulty: Moderate40.In reality, demand and prices are highly uncertain and are likely to fluctuate during the life of any supply chain decision.Answer: TrueDifficulty: Moderate41.The goal of aggregate planning is to satisfy demand in a way that minimizes profit. Answer: FalseDifficulty: Easy42.Aggregate planning is a process by which a company determines levels of capacity, production, subcontracting, inventory, stockouts, and even pricing over a specified time horizon. Answer: TrueDifficulty: Moderate43.Aggregate planning solves problems involving aggregate decisions rather than stock keeping unit (SKU) level decisions.Answer: TrueDifficulty: Easy44.Forecasting errors are dealt with in aggregate plans using either safety backlog or safety capacity.Answer: FalseDifficulty: Moderate45.Safety inventory is defined as inventory held to satisfy demand that is higher than forecasted. Answer: TrueDifficulty: Easy46.Safety capacity is defined as capacity used to satisfy demand that is lower than forecasted. Answer: FalseDifficulty: Easypanies should work with downstream partners to produce forecasts and with upstream partners to determine constraints when doing aggregate planning.Answer: TrueDifficulty: Easy48.The aggregate plan should be viewed primarily as an in-house tool that does not need to be communicated to supply chain partners.Answer: FalseDifficulty: Easy49.Given that forecasts are always wrong to some degree, the aggregate plan needs to have some flexibility built into it if it is to be useful.Answer: TrueDifficulty: Moderate50.With supply and demand management decisions being made independently, it is easier to coordinate the supply chain, thereby increasing profit.Answer: FalseDifficulty: Moderate51. A firm can vary supply of product by controlling production capacity and inventory.Answer: TrueDifficulty: Easy52. A firm that uses flexible work hours from the workforce to manage capacity to better meet demand is using a seasonal workforce.Answer: FalseDifficulty: Moderate53.Offering a promotion during a peak period that has significant forward buying creates even more variable demand than before the promotion.Answer: TrueDifficulty: Easy54.Average inventory decreases if a promotion is run during the peak period and increases if the promotion is run during the off-peak period.Difficulty: Easy55.Promoting during a peak demand month may decrease overall profitability if a significant fraction of the demand increase results from a forward buy.Answer: TrueDifficulty: Hard56.As forward buying becomes a smaller fraction of the demand increase from a promotion, it is less profitable to promote during the peak period.Answer: FalseDifficulty: Hard57.As the product margin declines, promoting during the peak demand period becomes less profitable.Answer: TrueDifficulty: Easy58.Cycle inventory exists because producing or purchasing in large lots allows a stage of the supply chain to exploit economies of scale and increase cost.Answer: FalseDifficulty: Moderate59. A lot or batch size is the quantity that a stage of the supply chain either produces or purchases at a given time.Answer: TrueDifficulty: Moderate60.Cycle inventory is the physical inventory in the supply chain due to either production or purchases demanded by the customer.Answer: TrueDifficulty: Moderate61.The inventory profile is a plot depicting the level of inventory over time.Answer: TrueDifficulty: Easy62. A discount is volume-based if the pricing schedule offers discounts based on the quantity ordered in a single lot.Answer: FalseDifficulty: Hard63. A discount is volume-based if the discount is based on the total quantity purchased over a given period, regardless of the number of lots purchased over that period.Difficulty: Easy64.Pricing schedules with all unit quantity discounts encourage retailers to increase the size of their lots, which reduces the average inventory and flow time in a supply chain.Answer: FalseDifficulty: Moderate65.Safety inventory is inventory carried for the purpose of satisfying demand that exceeds the amount forecasted for a given period.Answer: TrueDifficulty: Moderate66.Safety inventory is carried because demand forecasts are accurate and a product shortage may result if the forecast demand exceeds the actual demand.Answer: FalseDifficulty: Moderate67.Raising the level of safety inventory increases product availability and thus the margin captured from customer purchases.Answer: TrueDifficulty: Moderate68.Raising the level of safety inventory increases inventory holding costs.Answer: TrueDifficulty: Easy69.Carrying excessive inventory can help counter demand volatility when new products come on the market.Answer: FalseDifficulty: Moderate70.The appropriate level of safety inventory is determined by the uncertainty of both demand and supply and the desired level of cycle inventory.Answer: FalseDifficulty: Moderate71.As the uncertainty of supply or demand grows, the required level of safety inventories increases.Answer: TrueDifficulty: Moderate72.As the desired level of product availability increases, the required level of safety inventory decreases.Difficulty: Easy73. Lead time is the gap between when an order is placed and when it is received. Answer: TrueDifficulty: Easy74.Periodic review policies require more safety inventory than continuous review policies for the same level of product availability.Answer: TrueDifficulty: Easy75.When using a continuous review policy, a manager has to account for the uncertainty of demand during the lead time and the review interval.Answer: FalseDifficulty: EasyMultiply Choice1.Which of the following is not a stage within a typical supply chain?a.Customersb.Retailersc.Wholesalers/Distributorsd.Manufacturerse.All of the above are stages within a typical supply chain.Answer: eDifficulty: Easy2.Supply chain profitability isa.not correlated to the value generated by the various stages of the supply chain.b.the total profit to be shared across all supply chain stages.c.the difference between the revenue generated from the customer and the overall cost across the supply chain.d.the total revenue generated by the distributor stage of the supply chain.e. b and c onlyAnswer: eDifficulty: Difficult3.Successful supply chain management requires which of the following decision phases?a.supply chain strategy/designb.supply chain planningc.supply chain operationd.all of the abovee. a and b onlyAnswer: dDifficulty: Moderate4.The objective of customer order entry is toa.get the correct orders to customers by the promised due date at the lowest possible cost.b.maintain a record of product receipt and complete payment.c.maximize the conversion of customer arrivals to customer orders.d.ensure that orders are quickly and accurately entered and communicated to other affected supply chain processes.e.none of the aboveAnswer: dDifficulty: Easy5.The push/pull view of the supply chain is useful when considering strategic decisions relating to supply chain design, becausea.it categorizes processes based on whether they are initiated in response to or in anticipation of customer orders.b.it specifies the roles and responsibilities of each member of the supply chain.c.it clearly defines the processes involved and the owners of each process.d.it focuses on processes that are external to the firm.e.it focuses on processes that are internal to the firm.Answer: aDifficulty: Hard6.Which of the following statements about pull processes is accurate?a.May also be referred to as speculative processes.b.Execution is initiated in anticipation of customer orders.c.At the time of execution, demand must be forecast.d.May also be referred to as reactive processes.e.None of the above are accurate.Answer: dDifficulty: Easy7.Which of the following statements about push processes is accurate?a.May also be referred to as speculative processes.b.Execution is initiated in response to customer orders.c.At the time of execution, demand is known with certainty.d.May also be referred to as reactive processes.e.None of the above are accurate.Answer: aDifficulty: Easy8.Supply chain macro processes include which of the following?a.Customer Relationship Management (CRM)b.Internal Supply Chain Management (ISCM)c.Supplier Relationship Management (SRM)d.all of the abovee.none of the aboveAnswer: dDifficulty: Easy9.

SCM encompasses the planning, implementation, and control of the flow and storage of goods, services, and information from the point of origin to the point of consumption. The complexities involved in managing a supply chain are multifaceted and require a deep understanding of logistics, inventory, transportation, and inter-organizational relationships.Understanding the Supply Chain StructureAt its core, a supply chain consists of various entities including suppliers, manufacturers, distributors, retailers, and customers. Each entity plays a critical role in ensuring the smooth operation of the chain. For instance, suppliers provide raw materials or components, manufacturers transform these inputs into finished products, distributors manage the movement of goods, and retailers facilitate the sale to end consumers.Strategic Planning in Supply Chain ManagementStrategic planning is a foundational element in SCM as it allows organizations to anticipate future demand and make informed decisions about resource allocation. This process involves market research, demand forecasting, and the development of a long-term plan to guide the entire supply chain. Strategies may include diversifying supply sources, implementing just-in-time (JIT) manufacturing, or investing in technology to enhance efficiency.Operational Efficiency through Process OptimizationEfficient processes are essential for reducing waste, minimizing costs, and improving customer satisfaction. Techniques such as lean management and six sigma can be applied to identify and eliminate inefficiencies within the supply chain. By streamlining operations, companies can achieve faster throughput times, lower inventory levels, and higher quality outputs.Inventory Management and ControlInventory management is a critical aspect of SCM as it directly affects cash flow and customer service levels. Effective inventory control requires accurate forecasting, monitoring stock levels, and implementing appropriate inventory policies such as economic order quantity (EOQ) or critical ratio analysis. By maintaining optimal inventory levels, organizations can avoid stockouts and overstocking, which can lead to lost sales and increased carrying costs.Transportation and Logistics CoordinationThe transportation of goods is a significant component of SCM, involving decisions on mode of transport, route selection, and carrier management. Efficient logistics coordination ensures timely delivery of products while controlling transportation costs. Advancements in technology, such as vehicle tracking systems and real-time data analytics, have transformed the way logistics are managed, allowing for greater visibility and responsiveness in transportation networks.Technology Integration for Enhanced VisibilityThe integration of technology has become indispensable in modern supply chains. Enterprise Resource Planning (ERP) systems, RFID tags, and other digital tools provide real-time data on inventory levels, supplier performance, andproduction schedules. This enhanced visibility enablescompanies to respond quickly to changes in demand or supply chain disruptions, thus maintaining operational agility.Risk Management and Contingency PlanningSupply chains are vulnerable to risks such as natural disasters, political instability, or economic fluctuations. Risk management involves identifying potential threats, assessing their impact, and developing contingency plans to mitigate these risks. Diversifying suppliers, building safety stock, and establishing alternative sourcing strategies are common approaches to safeguard against unforeseen events.Sustainability in Supply Chain ManagementSustainability has emerged as a key consideration in SCM. Organizations are increasingly held accountable for their environmental impact and social responsibilities. Sustainable practices include reducing carbon footprint through efficient transportation methods, minimizing waste through recyclinginitiatives, and ensuring ethical sourcing by monitoring labor conditions at supplier facilities.ConclusionSupply chain management is an ever-evolving field that demands continuous improvement and adaptation to remain competitive. By embracing strategic planning, process optimization, inventory control, logistics coordination, technology integration, risk management, and sustainability practices, organizations can navigate the complexities of their supply chains and achieve operational excellence. As global markets continue to expand and consumer demands shift, those who master the art of supply chain management will undoubtedly secure a competitive edge in their respective industries.。

CHAPTER THIRTEENDiscussion Questions1.Consider two products with the same cost but different margins. Which productshould have a higher level of product availability? Why?The product with the higher margin should be stocked at a higher level of availability than the product with the lower margin. The product with the higher margin will have a higher Cu, which is the cost of understocking. The cost of understocking is the sale price less the cost and may be thought of by the supplier as profit foregone. A higher cost of understocking results in a higher critical fractile, so the optimal cycle service level will be higher, which will yield a higher availability.2.Consider two products with the same margin carried by a retail store. Any leftoverunits of one product are worthless. Leftover units of the other product can be sold to outlet stores. Which product should have a higher level of availability? Why?The product with the higher salvage value should be stocked at a higher level ofavailability than those with the lower salvage value. The product with the higher salvage value will have a lower Co, which is the cost of overstocking. The cost of overstocking is the sale price less the salvage value. A lower cost of overstocking results in a highercritical fractile, so the optimal cycle service level will be higher, which will yield a higher availability.3. A firm improves its forecast accuracy using better marketing intelligence. Whatimpact will this have on supply chain inventories and profitability? Why?Improved forecast accuracy should result in a closer match between supply and demand, resulting in improved profitability. An improved match will result in lower levels ofunplanned carryover inventory and shortages at the end of planning periods. Theimproved match will lower the expected costs of having too much or too little inventory.4.How can postponement of product differentiation be used to improve supply chainprofitability?Postponement refers to the delay of product differentiation until closer to the sale of the product. Postponement allows producers to leverage two features common to forecasts: forecasts with shorter time horizons tend to be more accurate than those with longer time horizons; and aggregate forecasts tend to be more accurate than forecasts for individual items/models. More accurate forecasts allow for a better match of supply and demand, thereby lowering mismatch costs and increasing profitability as discussed in the previous question.5.What are some scenarios in which postponing product differentiation across allproducts may not be profitable? How can tailored postponement help in suchsituations?Postponement is valuable in a supply chain when a firm sells a large variety of products with highly unpredictable demand of about the same size that is not positively correlated.Postponement is not as valuable if a large fraction of the demand comes from a fewproducts. In such a setting, tailored postponement is most effective whereby base loads are not postponed but the variation is postponed.6.Zara has used local production in Europe to have short replenishment lead times.How does this capability of quick response help the company improve profits in a highly volatile trendy apparel marketplace?In a trendy apparel market there exists a high probability for inventory obsolescence due to the nature of the industry. Therefore, by postponing the final configuration of thegoods, Zara provides flexibility to its inventory to minimize this trend and better meet the ever changing demand.7.When can tailored sourcing be used to improve supply chain profits? What aresome challenges with implementing tailored sourcing?In tailored sourcing, firms use a combination of two supply sources, one focusing on cost but unable to handle uncertainty, and the other focusing on flexibility to handleuncertainty but at a higher cost. For tailored sourcing to be effective, having supplysources such that one serves as the backup to the other is not sufficient. The two sources must focus on different capabilities. The low-cost source must focus on being efficient and should be required to supply only the predictable portion of the demand. The flexible source should focus on being responsive and be required to supply the uncertain portion of the demand. As a result, tailored sourcing allows a firm to increase its profits and better match supply and demand.。
供应链管理(中英对照)
Supply Chain Management供应链管理The so-called supply chain, in fact, from suppliers, manufacturers, warehouses, distribution centers and channels, and so constitute a logistics network. The same enterprise may constitute the different components of this network node, but the situation is different from a corporate network in different nodes. For example, in a supply chain, companies may not only in the same manufacturers, storage nodes, and in distribution centers, such as possession node location. In the more detailed division of labor, the higher the professional requirements of the supply chain, different nodes are basically composed by different enterprises. In the supply chain flows between the member units of raw materials, finished products, such as inventory and production constitutes the supply chain of goods flow.所谓供应链，其实就是由供应商、制造商、仓库、配送中心和渠道商等构成的物流网络。

Discuss the primary objective and operational parameters of aggregate planning.Answer: The goal of aggregate planning is to satisfy demand in a way thatmaximizes profit. Aggregate planning is a process by which a companydetermines levels of capacity, production, subcontracting, inventory, stockouts,and even pr icing over a specified time horizon. The aggregate planner’s mainobjective is to identify the following operational parameters over the specifiedtime horizon:• Production rate: the number of units completed per unit time (such as per week or per month).• Workforce: the number of workers/units of capacity needed for production.• Overtime: the amount of overtime production planned.• Machine capacity level: the number of units of machine capacity needed forproduction.• Subcontracting: the subcontracted capacity required over the planning horizon.• Backlog: demand not satisfied in the period in which it arises but carried over to future periods.• Inventory on hand: the planned inventory carried over the various periods in the planning horizon.The aggregate plan serves as a broad blueprint for operations and establishesthe parameters within which short-term production and distribution decisions are made. The aggregate plan allows the supply chain to alter capacity allocationsand change supply contracts.Difficulty: Moderate2. Discuss the information required for aggregate planning.Answer: An aggregate planner requires the following information:• Demand forecast F t for each Period t in the planning horizon that extends over T periods• Production cos ts• Labor costs, regular time ($/hour), and overtime costs ($/hour)• Cost of subcontracting production ($/unit or $/hour)• Cost of changing capacity; specifically, cost of hiring/laying off workforce($/worker) and cost of adding or reducing machine capacity ($/machine)• Labor/machine hours required per unit• Inventory holding cost ($/unit/period)• Stockout or backlog cost ($/unit/period)• Constraints:• Limits on overtime• Limits on layoffs• Limits on capital available• Limits on stockouts and ba cklogs• Constraints from suppliers to the enterpriseThis information is used to create an aggregate plan that in turn helps a company make the following determinations:• Production quantity from regular time, overtime, and subcontracted time:used to determine number of workers and supplier purchase levels.• Inventory held: used to determine how much warehouse space andworking capital is needed.• Backlog/stockout quantity: used to determine what the customer servicelevels will be.• Workforce hired/laid off: used to determine any labor issues that will beencountered.• Machine capacity increase/decrease: used to determine if newproduction equipment needs to be purchased or idled.The quality of an aggregate plan has a significant impact on the profitability of a firm. A poor aggregate plan can result in lost sales and lost profits if the available inventory and capacity are unable to meet demand. A poor aggregate plan mayalso result in a large amount of excess inventory and capacity, thereby raisingcosts. Therefore, aggregate planning is a very important tool in helping a supply chain maximize profitability.Difficulty: Hard3. Explain the basic strategies that an aggregate planner has available to balancethe various costs and meet demand.Answer: There are essentially three distinct aggregate planning strategies forachieving balance between these costs. These strategies involve trade-offsbetween capital investment, workforce size, work hours, inventory, andbacklogs/lost sales. Most strategies that a planner actually uses are acombination of these three and are referred to as mixed strategies. The threestrategies are as follows:1. Chase strategy—using capacity as the lever: With this strategy, the productionrate is synchronized with the demand rate by varying machine capacity or hiring and laying off employees as the demand rate varies. In practice, achieving thissynchronization can be very problematic because of the difficulty in varyingcapacity and workforce on short notice. This strategy can be expensive toimplement if the cost of varying machine or labor capacity over time is high. Itcan also have a significant negative impact on the morale of the workforce. TheChase strategy results in low levels of inventory in the supply chain and highlevels of change in capacity and workforce. It should be used when the cost ofcarrying inventory is very expensive and costs to change levels of machine andlabor capacity are low.2. Time flexibility strategy—using utilization as the lever: This strategy may beused if there is excess machine capacity (i.e., if machines are not used twentyfour hours a day, seven days a week). In this case, the workforce (capacity) iskept stable but the number of hours worked is varied over time in an effort tosynchronize production with demand. A planner can use variable amounts ofovertime or a flexible schedule to achieve this synchronization. Although thisstrategy does require that the workforce be flexible, it avoids some of theproblems associated with the Chase strategy, most notably changing the size of the workforce. This strategy results in low levels of inventory but with loweraverage utilization. It should be used when inventory carrying costs are relatively high and machine capacity is relatively inexpensive.3. Level strategy—using inventory as the lever: With this strategy, a stablemachine capacity and workforce are maintained with a constant output rate.Shortages and surpluses result in inventory levels fluctuating over time. Hereproduction is not synchronized with demand. Either inventories are built up inanticipation of future demand or backlogs are carried over from high- to low-demand periods. Employees benefit from stable working conditions. A drawback associated with this strategy is that large inventories may accumulate andcustomer orders may be delayed. This strategy keeps capacity and costs ofchanging capacity relatively low. It should be used when inventory carrying andbacklog costs are relatively low.Difficulty: Moderate4. Discuss key issues to be considered when implementing aggregate planning.Answer: 1. Think beyond the enterprise to the entire supply chain. Mostaggregate planning done today takes only the enterprise as its breadth of scope.However, there are many factors outside the enterprise throughout the supplychain that can dramatically impact the optimal aggregate plan. Therefore, avoidthe trap of only thinking about your enterprise when aggregate planning. Workwith partners downstream to produce forecasts, with upstream partners todetermine constraints, and with any other supply chain entities that can improve the quality of the inputs into the aggregate plan. As the plan is only as good asthe quality of the inputs, using the supply chain to increase the quality of theinputs will greatly improve the quality of the aggregate plan. Also make sure tocommunicate the aggregate plan to all supply chain partners who will be affected by it.2. Make plans flexible because forecasts are always wrong. Aggregate plans arebased on forecasts of future demand. Given that these forecasts are alwayswrong to some degree, the aggregate plan needs to have some flexibility builtinto it if it is to be useful. By building flexibility into the plan, when future demand changes, or other changes occur, such as increases in costs, the plan canappropriately adjust to handle the new situation. A manager should performsensitivity analysis on the inputs into an aggregate plan. Using sensitivityanalysis on the inputs into the aggregate plan will enable the planner to choosethe best solution for the range of possibilities that could occur.3. Rerun the aggregate plan as new data emerges. Aggregate plans provide amap for the next three to eighteen months. This does not mean that a firm should only run aggregate plans once every three to eighteen months. As inputs into the aggregate plan change, managers should use the latest values of these inputsand rerun the aggregate plan. By using the latest inputs, the plan will avoidsuboptimization based on old data and will produce a better solution. Forinstance, as new demand forecasts become available, aggregate plans shouldbe reevaluated.4. Use aggregate planning as capacity utilization increases. Surprisingly, manycompanies do not create aggregate plans and instead rely solely on orders from their distributors or warehouses to determine their production schedules. Theseorders are driven either by actual demand or through inventory managementalgorithms. If a company has no trouble efficiently meeting demand this way,then one could claim the lack of aggregate planning may not significantly harmthe company. However, when utilization becomes high and capacity is an issue, relying on orders to set the production schedule can lead to capacity problems.When utilization is high, the likelihood of producing for all the orders as theyarrive is very low. Planning needs to be done to best utilize the capacity to meet the forecasted demand. Therefore, as capacity utilization increases, it becomesmore important to perform aggregate planning.Difficulty: Moderate。

供应链管理英文 Chapter 4 - Blue Nile case study answers
The learning objectives of the case are to (1) understand the link between supply chain structure and financial performance, (2) identify key drivers of supply chain performance and how they affect a firm's ability to respond during periods of strong or weak demand, and (3) develop the alignment between supply chain structure and strategic position for a firm.To this end, the case highlights the supply chain structures and performances of three firms in the diamond retailing industry: Blue Nile, Zales, a nd Tiffany. Blue Nile’s supply chain structure is geared toward a pure centralized e-business; Zales sells merchandise primarily through stores but recently added an online channel; and Tiffany also uses an online channel but most of its diamond and other high-end products are sold through stores. The case is designed to foster discussion of the three supply chain structures and encourage students to evaluate the firms’ performance in terms of components of customer service such as response time, product variety, product availability, customer experience, order visibility, and returnability, coupled with cost factors that include inventory, transportation, information, and facilities.1. What are some key success factors in diamond retailing? How do Blue Nile, Zales, and Tiffany compare on those dimensions?As with most retailing, the key success factors in diamond retailing can be measured by customer service factors and cost factors. Given the varied supply chain components and supply chain costs. Blue Nile has a distinct advantage in product variety and product availability since customers can “build their own ring” by choosing from an inventory of about 75,000 stones. Customers purchasing at Tiffany and, until recently, at Zales have been limited to the inventory available at the store. Customers who are comfortable making large purchases online will find the low-pressure purchasing experience at Blue Nile, supported by the educational Web site, salaried sales support, and thirty-day return guarantee, appealing. Given that the jewelry is made to order, clients at Blue Nile must be willing to wait to receive their orders, unlike at Tiffany or Zales.The Tiffany brand is very strong and well established. It is associated with glamour, trust, and customer service. These associations allow the company to sell at higher margins than its competitors. Diamond and other high-end jewelry purchases are expensive, and many customers will trade off other factors for the Tiffany customer experience when making such purchases. Moreover, when spending thousands of dollars for a single item, customers often want to see and feel what they are buying.Zales does not have the product variety and availability that Blue Nile provides, nor does it have the brand name advantage that Tiffany enjoys. The weaker brand is reflected in the firm’s margins, which are lower than those of Tiffany. Blue Nile’s focus on low prices is reflected in the lower margins it has relative to both Zales and Tiffany.Blue Nile operates out of one warehouse, with its entire inventory at this facility. The inventories at both Tiffany and Zales are disaggregated through their stores. High-end jewelry items are high-priced, have relatively low demand, and have high demand variability. Such items realize the most savings in inventory holding cost through lower safety stock inventory when the inventory is aggregated. Further, since items sold through the Blue Nile Web site are customized, the inherent postponement allows the company to keep inventory aggregated longer, thus reducing safety inventory even more. While Blue Nile’s inventory-to-sales ratio is around 6 percent, the ratios for both Tiffany and Zales are about 40 percent. Blue Nile’s supply chain structure also gives it a major advantage in facility costs.Blue Nile operates primarily from one warehouse in the United States. Both Zales and Tiffany operate many stores, often in high-priced locations. In addition to stores all over the world, Tiffany has manufacturing facilities, a retail service center that supplies stores, and diamond processing centers in seven countries. While Tiffany has advantages from being vertically integrated, Blue Nile operates on a very low fixed-cost structure. Blue Nile’s property and equipment to net sales ratio was 2.37 percent in 2007, while Tiffany’s was more than 25 percent, down from 35 percent in 2006, and Zales’s was close to 14 percent. Blue Nile also has an advantage in facility operatingcosts. Because customers design, select, and order jewelry on the Web site, the company does not incur the level of human resources costs in the form of sales staff that Tiffany and Zales do.Transportation costs, as with most e-retailers, are higher at Blue Nile than at Tiffany or Zales. The outbound transportation distance and hence costs and time tend to be much higher when inventories are aggregated, as is the case at Blue Nile. In the case of Tiffany and Zales, some economies of scale can still be realized on inbound transportation at all downstream stages of the supply chain until the merchandise hits retail stores, and the customer takes care of the last mile of outbound transportation costs.The companies do not seem to differentiate themselves from each other on any other customer service components, such as time to market, order visibility and returnability, or cost of information.2. What do you think of the fact that Blue Nile carries about 30,000 stones priced at $2,500 or higher while almost 60 percent of the products sold from the Tiffany Web site are priced around $200? Which of the two product categories is better suited to the online channel?There are different reasons why these two firms carry very different types of items on their Web sites. In the case of Blue Nile, the primary reasons could be the savings in inventory holding cost due to lower safety stocks and the broad product variety andproduct availability that the firm can offer customers. Stones priced at $2,500 or higher are unique, high-value items with relatively low demand and high demand variability. The high demand variability necessitates carrying larger safety stock in order to meet required customer service levels. Given the high price of the stones, the cost of holding them in inventory is proportionally higher. Aggregating inventory reduces the amount of safety stock required since the demand variability is less than in a disaggregated scenario. By aggregating the inventory in the online channel, Blue Nile also broadens the product availability and variety available to customers. It is a smart move for Blue Nile to aggregate and carry its high-priced products with low demand and high demand variability on an online channel.The Tiffany brand is built on the glamour, luxury, and quality that customers perceive when visiting a Tiffany store. This perception is a result of both the products and the service. The company’s inventory includes a wide variety of items ranging from very high-end diamond jewelry to basic but elegant tableware. Tiffany has stores as small as 1,300 square feet, and in 2008 the firm began opening stores of about 2,000 square feet selling high-margin products in affluent U.S. areas. Given the strategic importance of the brand image, the breadth of inventory, and the push toward smaller facilities and lower cost, it makes sense for Tiffany to position the high-end luxury products at the store and move the D items to the online channel. This allows it to utilize the limited facility space to highlight the high-end items and customer service and offer the lower-end items online, where product substitution can be used as means of aggregating inventory and lowering safety stocks for the D items. This structure, however, puts Tiffany at a cost disadvantage relative to Blue Nile because Tiffany decentralizes its high-value items with low demand and high variety while centralizing its lower-value items. Such a cost disadvantage can be justified as long as Tiffany can maintain its strong brand and associate it with the store experience.3. What do you think of Tiffany’s decisi on to not sell diamonds online?Although on the surface, this strategy would seem to be an appropriate approach for better market penetration and customer reach, Tiffany is in danger of exacerbating its inventory and property expenses. Opening the smaller retail outlets will provide Tiffany’s an opportunity to reach out and “touch” customers in these areas, a key success factor for them in the diamond business. It will provide the opportunity for these customers to experience the Tiffany “service” and “brand” without having to go the larger cities. However, opening these stores will require Tiffany’s to up the inventory level throughout the supply chain. Not only will they have to have additional inventory at these stores, but the overall safety stock wi ll increase. In addition, Tiffany’s property expenses will increase as stores are opened.This is a strategy that seems flawed and should probably be reversed. Its model is better suited for larger stores in cities that will draw significant traffic. Moving into smaller cities with smaller stores is likely to raise costs far more than revenues.4. Given that Tiffany stores have thrived with their focus on selling high-end jewelry, what do you think of the failure of Zales with its upscale strategy in 2006? Zales’s upscale strategy was in response to fierce competition it was facing from mass merchant department stores such as Wal-Mart, national chain department stores such as JCPenney, and home shopping networks. Middle America had been Zales’s target market since its founding in 1924. A large portion of the company’s revenue came from value-oriented customers who frequented malls. The success of the Zales brand was built on the perception of the good value one got for the money, but with that came the perception of being inexpensive. While one can see why the company decided on the competitive repositioning, one must question the implementation. It takes much time and effort to educate new customers and transform a brand. Zales tried to make too many radical changes in too little time. The firm drastically changed its portfolio of products, 15 percent of the suppliers in the supply chain network were new and included new overseas vendors, and holiday promotions and monthly payment plans were eliminated, to name a few changes. All this resulted in the firm’s losing not only its core customer base but also sales due to delays in bringing merchandise in on time and not making inroads into new target markets.The basic premise of its strategy to move into selling high-end jewelry through its stores is also questionable. Given that it has a much weaker brand than Tiffany; Zales’s strategy of bringing high-end jewelry to its stores raised its inventory costs without raising its margins enough to offset this in crease. Zales’s inventories in FY 2006, when it tried the high-end strategy, rose to 47 percent of sales, even higher than Tiffany’s; its margins, however, remained lower than Tiffany’s. Poor execution hurt it further, but given that its brand is weaker th an Tiffany’s, one can question whether such a strategy would have had any chance of success even in the long term.5. Which of the three companies do you think was best structured to deal with weak economic times?A lean and nimble structure is an advantage in weak economic times. Blue Nile has a distinct advantage in this regard with its very low fixed-cost structure compared to Tiffany and Zales. Property and equipment to net sales ratios are 2.38, 13.93, and25.46 percent for Blue Nile, Zales, and Tiffany, respectively. Both Zales and Tiffany are contractually tied up in many medium- to long-term leases for their facilities. The selling, general, and administrative expenses at Tiffany and Zales are about four times those incurred at Blue Nile. Much of this discrepancy can be attributed to the costs of operating stores. Blue Nile also has a very low investment in inventory compared to the other two companies. The cost of sales at Blue Nile is higher, but this can attributed to the lower margins and the higher cost of outbound distribution. The low cost structure atBlue Nile is well suited for times when demand shrinks in the industry. Blue Nile should take advantage of its low cost structure and lower prices to get more market share. Zales is perhaps in the weakest position to handle weak economic times, given the inventory write-off it had to take when its high-end strategy failed. With tightened credit, Zales may find it difficult to survive. Tiffany certainly has the strength to survive but is hurt significantly by dropping sales, given its relatively high fixed costs.6. What advice would you give to each of the three companies regarding their strategy and structure?Blue Nile has a strategy that focuses on lower prices on a large variety of high-end stones that aligns very well with its centralized structure. Its marketing focus on convincing customers that the four Cs and third-party validation are the key ingredients when valuing a diamond is also well aligned with its structure, which does not allow customers to touch and see the stone before buying. Given its significant cost advantages and customers’ tendency to try to save money during difficult times, Blue Nile has a significant opportunity in this downturn. Blue Nile can take an aggressive position, emphasizing its lower prices with similar quality to very high-end diamond retailers. Although this is a difficult message to sell in general, it may be easier in the difficult economic environment of 2009.For Zales, positive recommendations are more difficult to make. From a financial perspective, Zales needs to get control of its inventories. One way to do this is to centralize more of its expensive diamond inventory, making it available to stores as needed. Lower-value diamonds could be stocked and sold from retail stores. For higher-end diamonds, rings with imitation stones could be used to help customers select a style, followed by having the real diamond installed later at a central location and shipped to the store for customer pick-up. Zales’s ideal situation seems to be one in which it stocks and sells lower-cost products from decentralized locations with higher-value stones centralized and provided on demand.Tiffany finds itself in a bit of a bind. It cannot centralize its high-end stones because that would conflict with its brand image. Pricing pressure at retail is likely to continue with the growth of Blue Nile at the high end and retailers such as Wal-Mart and Costco at the lower end. As a result, Tiffany has to continue working hard to maintain its brand image. Its move into the wholesale part of the diamond business has potential pluses—it gives the company the wholesale margin and could give it some form of exclusivity on its stones. For now, its sources of stones are very similar to those of its competitors.。
