Chapter1。
Iroduction to Supply Chain Management
1.【supply chain】The system of suppliers,manufacturers,transportation, distributors,and vendors
that exists to transform raw materials to final products and supply those products to customers.
2.【supply chain management】SCM is a business network covering from buying,making, moving,
warehousing to selling。
3.【What makes supply chain management difficult?】
①Supply chain strategies cannot be determined in isolation. They are directly affected by another chain
that most organizations have, the development chain。
②It is challenging to design and operate a supply chain so that total systemwide costs are minimized,
and systemwide service levels are maintained。
③Uncertainty and risk are inherent in every supply chain。
4.【Strategies for SCM】
①Global Optimization(全局优化)②Managing Uncertainty(管理不确定性)
5.【Why is Global Optimization Hard?】
①The supply chain is a complex network.
②Different facilities in the supply chain frequently have different,conflicting objectives。
③The supply chain is a dynamic system.
④System variations over time
6.【Why Is Uncertainty Hard to Deal With?】
①Matching supply and demand is a major challenge。
②Forecasting doesn’t solve the problem.
③Inventory and back-order levels typically fluctuate considerably across the supply chain,even when
customer demand for specific products does not vary greatly。
④Demand is not the only source of uncertainty.
⑤Recent trends such as lean manufacturing, outsourcing,and offshoring that focus on reduction
increase risks significantly。
7.【The three principles of all forecasting techniques】
①Forecasting is always wrong.②The longer the forecast horizon , the worse the forecast.
③Aggregate forecasts are more accurate.
Chapter2。
Inventory Management, Supply Contracts and Risk Pooling
1.【何时低(高)于平均需求】If the cost of not selling an additional unit is larger than the profit from
selling an additional unit, the optimal quantity in general will be less than average demand, while if the reverse is true, the optimal order quantity in general will be greater than average demand。
2.【平均需求与最优订货量的关系】The optimal order quantity is not necessarily equal to average,or
forecast demand。
3.【Coefficient of variation】
①Coefficient of variation=Standard deviation
Average demand
②The Standard deviation measures the absolute variability of customer demands, the coefficient of
variation measures variability relative to average demand。
4.【Risk Pooling:three critical points】
①Centralizing inventory control reduces both safety stock and average inventory level for the same
service level.
②The higher the coefficient of variation,the greater the benefit obtained from centralized systems; that
is, the greater the benefit from risk Pooling.
③The benefits from risk Pooling depend on the behavior of demand from one market relative to demand
from another。
5.【Forecasting Methods】
①Judgment methods(判断方法)②Market research methods(市场研究方法)①②为定性方法
③Time Series methods(时间序列方法)④Causal methods(因果方法)③④为定量方法.
6.【Inventory Management’s controlling methods】
①Continuous review policy(持续检查策略)②Periodic review policy(定期检查策略)
7.【(s,S)Policy】Whenever the inventory position drops below a certain level,s,we order to raise
the inventory position to level S.
(s, S)的计算:
①The reorder point (s) has two components:
a.To account for average demand during lead time: LT×A VG
b.To account for deviations from average (we call this safety stock):
z×STD×√LT
where z is chosen from statistical tables to ensure that the probability of stockouts during leadtime is 100%-SL。
②Since there is a fixed cost, we order more than up to the reorder point:
Q=√(2×K×AVG)÷ℎ
③The total order-up-to level is:S=Q+s
注:A VG = average daily demand
STD = standard deviation of daily demand
LT = replenishment lead time in days
h = holding cost of one unit for one day
SL = service level (for example, 95%)。
This implies that the probability of
Stocking out is 100%—SL (for example, 5%)
K = fixed cost
Also,the Inventory Position at any time is the actual inventory plus items
already ordered, but not yet delivered。
8.【Judgment Methods】
①Assemble the opinion of experts
②Sales—force composite combines salespeople's estimates(销售人员汇集意见)
③Panels of experts – internal,external, both(专家座谈)
④Delphi method(德尔菲方法):
a.Each member surveyed
b.Opinions are compiled
c.Each member is given the opportunity to change his opinion。
9.【Supply Contracts】
①Buy—Back Contracts(回购合同):The seller agrees to buy back unsold goods from the buyer for
some agreed-upon price higher than the salvage value。
②Revenue-Sharing Contracts(收入共享合同):The buyer shares some of its revenue with the seller, in
return for a discount on the wholesale price.
③Global Optimization Contracts(全局优化合同):This unbiased decision maker would consider the
two supply chain partners, the supplier and the buyer, as two members of the same organization。
That is,the transfer of money between the parties is ignored and the unbiased decision maker will maximize supply chain profit。
④Quantity Flexibility Contracts(数量灵活合同):Supplier provides full refund for returned items as
long as the number of returns is no larger than a certain quantity。
⑤Sales Rebate Contracts(销售回扣合同):Supplier provides a direct incentive to the retailer to
increase sales by means of a rebate paid by the supplier for any item sold above a certain quantity。

designer。
Chapter4.The Value of Information
1.【“In modern supply chains, information replaces inventory”】I think it is true because information:
①Helps reduce variability②Helps improve forecasts③Enables coordination of systems and strategies
④Improves customer service⑤Facilitates lead time reductions
⑥Enables firms to react more quickly to changing market conditions.
2.【What is the Bullwhip Effect?】Order variability is amplified(放大)the supply chain;upstream
echelons(梯度)face higher variability.
3.【What are the causes the Bullwhip Effect?】
①Promotional sales:Forward buying
②V olume and transportation discounts:Batching
③Inflated orders:IBM Aptiva orders increased by 2-3 times when retailers thought that IBM would be
out of stock over Christmas
④Demand forecasting:Order-up—to points are modified as forecasts change – orders increase more
than forecasts
⑤Long cycle times:Long lead times magnify this effect
4.【Methods for Coping with the Bullwhip Effect】
①Reduce uncertainty:POS;Sharing information; Sharing forecasts and policies
②Reduce variability:Eliminate promotions;Year-round low pricing
③Reduce lead times:EDI;Cross docking
④Strategic partnerships:Vendor managed inventory (VMI);Data sharing
