A地冷链物流运输安全研究-文献综述
文献综述冷链物流运输安全研究1 关于冷链物流研究的历史回顾物流概念于20世纪70年代末由日本传入我国,国内对物流研究只有30年的历史。
而对冷链物流的研究则更晚,冷链物流的大量研究成果还是出现在2000年以后。
从这些文献来看,主要形成了以下几方面的研究成果。
1.1物流的起源1915年,美国学者阿奇·萧在《市场流通中的若干问题》(Some Problem in MarketDistribution)中提出“Physical Distribution”(简称PD)概念,是目前学术界公认的最早的物流概念。
1935年,美国市场营销协会(American Market Association,AMA)在《市场营销用语集》中对物流的定义:“流是包含于销售之中的物质资料和服务于从生产地点到消费点流动过程中伴随的种种经济活动”。
1954年,AMA对物流的定义为:“所谓物流,就是物质资料从生产阶段移动到消费者或利用者手里,并对该移动过程进行管理”。
1962年,德鲁克提出“物流是经济界的黑暗大陆”的论断,物流成为企业挖掘利润源泉最重要的一块阵地。
1967年,美国国家配送管理协会(National Council of Physical Distribution Management,NCPDM)对物流的定义:“所谓物流,就是产成品从生产线的终点有效地移动到消费者手里的广范围的活动,有时包括从原材料的供给源到生产线的始点的移动”。
1974年,美国鲍尔索克斯在《物流管理》中,对物流的定义:“以卖主为起点将原材料、零部件与制成品在各个企业之间有策略地加以流转,最后到达用户,期间所需要的一切活动的管理过程”。
1.2 冷链物流的起源冷链物流起源于19世纪上半叶冷冻机的发明,后又随着电冰箱的出现,各种保鲜盒冷冻食品开始陆续进入市场和消费者家庭。
20世纪30年代后,欧美的主要是食品冷链体系已经初步建立。
40年代,欧洲的冷链虽然在二战中被摧毁,但战后又很快重建。

The Cold Chain and its LogisticsAuthors: Dr. Jean-Paul Rodrigue and Dr. Theo Notteboom1. OverviewWhile Globalization has made the relative distance between regions of the world much smaller, the physical separation of these same regions is still a very important reality. The greater the physical separation, the more likely freight can be damaged in one of the complex transport operations involved. Some goods can be damaged by shocks while others can be damaged by undue temperature variations. For a range of goods labeled as perishables, particularly food, their quality degrades with time since they maintain chemical reactions which rate can be mostly mitigated with lower temperatures. It takes time and coordination to efficiently move a shipment and every delay can have negative consequences, notably if this cargo is perishable. To ensure that cargo does not become damaged or compromised throughout this process, businesses in the pharmaceutical, medical and food industries are increasingly relying on the cold chain technology.The cold chain refers to the transportation of temperature sensitive products along a supply chain through thermal and refrigerated packaging methods and the logistical planning to protect the integrity of these shipments. Specialization has led many companies to not only rely on major shipping service providers such as the United Parcel Service (UPS) and FEDEX, but alsomore focused industry specialists that have developed a niche logistical expertise around the shipping of temperature sensitive products. The potential to understand local rules, customs and environmental conditions as well as an estimation of the length and time of a distribution route make them an important factor in global trade. As a result, the logistics industry is experiencing a growing level of specialization and segmentation of cold chain shipping in several potential niche markets within global commodity chains. Whole new segments of the distribution industry have been very active in taking advantage of the dual development of the spatial extension of supply chains supported by globalization and the significant variety of goods in circulation. From an economic development perspective, the cold chain enables many developing countries to take part in the global perishable products market. From a geographical perspective, the cold chain has the following impacts:Global. Specialization of agricultural functions permitting the transport of temperature sensitive food products to distant markets. Enables the distribution of vaccines and other pharmaceutical or biological products.Regional. Can support the specialization of functions and economies of scale, such as specialized laboratories.Local. Timely distribution to the final consumer, namely grocery stores and restaurants.2. Emergence of Cold Chain LogisticsWhile global commodity chains are fairly modern expansions in the transportation industry, the refrigerated movement of temperature sensitive goods is a practice that dates back to 1797 when British fishermen used natural ice to preserve their fish stock piles. This process was also seen in the late 1800s for the movement of food from rural areas to urban consumption markets, namely dairy products. Cold storage was also a key component of food trade between colonial powers and their colonies. For example, in the late 1870s and early 1880s, France was starting to receive large shipments of frozen meat and mutton carcasses from South America, while Great Britain imported frozen beef from Australia and pork and other meat from New Zealand. By 1910, 600,000 tons of frozen meat was being brought into Great Britain alone. The first reefer ship for the banana trade was introduced in 1903 by the United Food Company. This enabled the banana to move from an exotic fruit that had a small market because it arrived in markets too ripe, to one of the world's most consumed fruit. The temperature controlled movement of pharmaceuticals and medical supplies is a much more modern transit option than the shipping of refrigerated or frozen food. Since the 1950s, logistical third party companies began to emerge and institute new methods for successfully transporting these global commodities. Before their emergence, cold chain processes were mostly managed in house by the manufacturer. In the United States, Food and Drug Administration restrictions and accountability measures over the stability of the cold chain incited many of these companies to rely on specialty couriers rather thancompletely overhauling their supply chain facilities. A specialized industry was thus born. The value of the cold chain in the preservation of expensive vaccines and medical supplies was only beginning to be recognized when these logistical providers started to appear. As awareness began to grow, so did the need for efficient management of the cold chain.The reliance on the cold chain continues to gain importance. Within the pharmaceutical industry for instance, the testing, production and movement of drugs relies heavily on controlled and uncompromised transfer of shipments. A large portion of the pharmaceutical products that move along the cold chain are in the experiment or developmental phase. Clinical research and trials is a major part of the industry that costs millions of dollars, but one that also experiences a failure rate of around 80%. According to the Healthcare Distribution Management Association, of the close to 200 billion dollars in pharmaceutical distribution, about 10% are drugs that are temperature sensitive. This makes the cold chain responsible for transporting a near 20 billion dollar investment. If these shipments should experience any unanticipated exposure to variant temperature levels, they run the risk of becoming ineffective or even harmful to patients.Temperature control in the shipment of foodstuffs is a component of the industry that has continued to rise in necessity with international trade. As a growing number of countries focus their export economy around food and produce production, the need to keep these products fresh for extended periods of timehas gained in importance. Increasing income levels create a change in diet with amongst others a growing appetite for fresh fruit and higher value foodstuffs such as meat and fish. Persons with higher socioeconomic status and with more economic means are more likely to consume vegetables and fruit, particularly fresh, not only in higher quantities but also in greater variety. Consumers with increasing purchase power have become preoccupied with healthy eating, therefore producers and retailers have responded with an array of exotic fresh fruits originating from around the world.Any major grocery store around the world is likely to carry tangerines from South Africa, apples from New Zealand, bananas from Costa Rica and asparagus from Mexico. Thus, a cold chain industry has emerged to service these commodity chains. In 2002, an estimated 1200 billion dollars' worth of food was transported by a fleet of 400,000 refrigerated containers (Reefers). Alone, the United States imports about 30% of its fruits and vegetables and 20% of its food exports can be considered perishables. The uncompromised quality and safety of this food is often taken for granted, despite being the main reason behind the ability to sell the food. The cold chain serves the function of keeping food fresh for extended periods and eliminating doubts over the quality of the food products. In all the supply chains it is concerned with, cold chain logistics favor higher levels of integration since maintaining temperature integrity requires a higher level of control of all the processes involved. It may even incite third party logistics providers to acquire elements of the supply chainwhere time and other performance factors are the most important, even farming. This may involve the acquisition of produce farms (e.g. oranges) to insure supply reliability.3. Providing Temperature Controlled EnvironmentsThe success of industries that rely on the cold chain comes down to knowing how to ship a product with temperature control adapted to the shipping circumstances. Different products require different temperature level maintenance to ensure their integrity throughout the travel process. For instance, the most common temperature standards are "banana" (13 °C), "chill" (2 °C), "frozen" (-18 °C) and "deep frozen" (-29 °C). Staying within this temperature is vital to the integrity of a shipment along the supply chain and for perishables it enables to insure and optimal shelf life. Any divergence can result in irrevocable and expensive damage; a product can simply lose any market or useful value.Being able to ensure that a shipment will remain within a temperature range for an extended period of time comes down largely to the type of container that is used and the refrigeration method. Factors such as duration of transit, the size of the shipment and the ambient or outside temperatures experienced are important in deciding what type of packaging is required. They can range from small insulated boxes that require dry ice or gel packs, rolling containers, to a 53 footer reefer which has its own powered refrigeration unit. The major cold chain technologies involve:Dry ice. Solid carbon dioxide, is about -80°C and is capable of keeping a shipment frozen for an extended period of time. It is particularly used for the shipping of pharmaceuticals, dangerous goods and foodstuffs. Dry ice does not melt, instead it sublimates when it comes in contact with air.Gel packs. Large shares of pharmaceutical and medicinal shipments are classified as chilled products, which means they must be stored in a temperature range between 2 and 8°C. The common method to provide this temperature is to use gel packs, or packages that contain phase changing substances that can go from solid to liquid and vice versa to control an environment. Depending on the shipping requirements, these packs can either start off in a frozen or refrigerated state. Along the transit process they melt to liquids, while at the same time capturing escaping energy and maintaining an internal temperature.Eutectic plates. The principle is similar to gel packs. Instead, plates are filled with a liquid and can be reused many times.Liquid nitrogen. An especially cold substance, of about -196°C, used to keep packages frozen over a long period of time. Mainly used to transport biological cargo such as tissues and organs. It is considered as an hazardous substance for the purpose of transportation.Quilts. Insulated pieces that are placed over or around freight to act as buffer in temperature variations and to maintain the temperature relatively constant. Thus, frozen freight will remain frozen for a longer time period, often long enough not to justify the usage of more expensive refrigeration devices. Quilts can also beused to keep temperature sensitive freight at room temperature while outside conditions can substantially vary (e.g. during the summer or the winter). Reefers. Generic name for a temperature controlled container, which can be a van, small truck, a semi or a standard ISO container. These containers, which are insulated, are specially designed to allow temperature controlled air circulation maintained by an attached and independent refrigeration plant. The term increasingly apply to refrigerated forty foot ISO containers.Perishable or temperature sensitive items are carried in refrigerated containers (called "reefers"), that account for a growing share of the refrigerated cargo being transported around the world. While in 1980 33% of the refrigerated transport capacity in maritime shipping was containerized, this share rapidly climbed to 47% in 1990, 68% in 2000 and 90% in 2010. About 1.69 million TEUs of reefers were being used by 2009. All reefers are painted white to increase the albedo (share of the incident light being reflected; high albedo implies less solar energy absorbed by the surface) with the dominant size being 40 high-cube footers (45R1 being the size and type code). For instance a low albedo container can have its internal temperature increase to 50 °C when the external temperature reaches 25 °C on a sunny day while a high albedo container see its internal temperature increase to only 38 °C under the same conditions.The refrigeration unit of a reefer requires an electric power source during transportation and at a container yard. Regular containerships have 10 to 20% oftheir slots adapted to carry reefers, with some ships having up to 25% of their slots being dedicated. It is important to underline that the refrigeration units are designed to maintain the temperature within a prefixed range, not to cool it down. This implies that the shipment must be brought to the required temperature before being loaded into a reefer, which requires specialized warehousing and loading / unloading facilities. A new generation of reefers is coming online, which are equipped with an array of sensors monitoring effectively the temperature and shutting the cooling plant when unnecessary. This enables to improve the reliability of temperature control and well as extend the autonomy of the reefer.The growth of the intermodal transportation of reefers has increasingly required transport terminals, namely ports, to dedicate a part of their storage yards to reefers. This accounts between 1% to 5% of the total terminal capacity, but can be higher for transshipment hubs. The stacking requirements simply involve having an adjacent power outlet, but the task is more labor intensive as each container must be plugged and unplugged manually and the temperature to be monitored regularly as it is the responsibility of the terminal operator to insure that the reefers keep their temperature within preset ranges. This may also forbid the usage of an overhead gantry crane implying that the reefer stacking area can be serviced by different equipment. Even if reefers involve higher terminal costs, they are very profitable due to the high value commodities they transport.4. The Setting and Organization of Cold ChainsMoving a shipment across the supply chain without suffering any setbacks or temperature anomalies requires the establishment of a comprehensive logistical process the maintain the shipment integrity. This process concerns several phases ranging from the preparation of the shipments to final verification of the integrity of the shipment at the delivery point:Shipment preparation. When a temperature sensitive product is being moved, it is vital to first assess its characteristics. A key issue concerns the temperature conditioning of the shipment, which should be already at the desired temperature. Cold chain devices are commonly designed to keep a temperature constant, but not to bring a shipment to this temperature, so they would be unable to perform adequately if a shipment is not prepared and conditioned. Other concerns include the destination of the shipment and the weather conditions for those regions, such as if the shipment will be exposed to extreme cold or heat along the transport route.Modal choice. Several key factors play into how the shipment will be moved. Distance between the origin and the final destination (which often includes a set of intermediary locations), the size and weight of the shipment, the required exterior temperature environment and any time restrictions of the product all effect the available transportation options. Short distances can be handled with a van or truck, while a longer trip may require an airplane or a container ship. Custom procedures. If the freight crosses boundaries, custom procedures can become very important, since cold chain products tend to be time sensitive andmore subject to inspection than regular freight (e.g. pharmaceuticals and biological samples). The difficulty of this task differs depending on the nation (or economic bloc) and the gateway since there are variations in procedures and delays.The "Last Mile". The last stage is the actual delivery of the shipment to its destination, which in logistics is often known as the “last mile”. Key considerations when arranging a final delivery concern not only the destination, but the timing. Trucks and vans, the primary modes of transportation for this stage, must meet the specifications necessary to transfer the cold chain shipment. Also important is the final transfer of the shipment into the storage facilities as there is potential for a breach of integrity.Integrity and quality assurance. After the shipment has been delivered, any temperature recording devices or known temperature anomalies must be recorded and made known. This is the step of the logistical process that creates trust and accountability, particularly if liability for a damaged shipment is incurred. If problems or anomalies that compromise a shipment do occur, an effort must be made to identify the source and find corrective actions. Therefore, the setting and operation of cold chains is dependent on the concerned supply chains since each cargo unit to be carried has different requirements in terms of demand, load integrity and transport integrity.5. Food TransportationThere is a variety of methods for the transport of food products with the banana accounting for the world's most significant commodity transported in the food cold chain with 20% of all seaborne reefers trade. Land, sea and air modes all have different structures for keeping food fresh throughout the transport chain. Innovations in packaging, fruit and vegetable coatings, bioengineering (controlled ripening), and other techniques reducing the deterioration of food products have helped shippers extend the reach of perishable products. For food products such as fruits and vegetables, time has a direct impact on their shelf life and therefore on the potential revenue a consignment may generate. Concomitantly, new transport technologies have permitted the shipment of perishable products over longer distances. For instance, improved roads and intermodal connections along the African coast reduced transport time for food to European markets from 10 days to 4 days.Certain domestic or transnational supply chains may only require one transportation mode, but many times ground shipments are one link in a combination of transport modes. This makes intermodal transfer critical for the cold chain. Intermodal shipments typically use either 20 or 40 footers refrigerated containers that are capable of holding up to 26 tons of food. The container makes loading and unloading periods shorter and less susceptible to experiencing damage. The environments in these containers are currently controlled electronically by either plugging into a generator or power source on the ship or truck, but early food shipments would cycle air from stores of wet ordry ice to keep the food refrigerated. The efficiency of cold chain logistics permitted the consolidation of cold storage facilities.Moving away from ice refrigeration has allowed for much greater distances to be traveled and has greatly increased the size of the global food market, enabling many developing countries to capture new opportunities. Another efficient mode for transporting foodstuffs is air travel. While this is a preferred form of travel for highly perishable and valuable goods due to its ability to move much faster over longer distances, it does lack the environment control and transfer ease of the ground and sea transports. Also, during the flight the cargo is stored in a 15°C – 20°C environment, but close to 80% of the time the package is exposed to exterior weather while waiting to be loaded onto the plane or being moved to and from the airfield. This is troubling considering the value of the food and the importance placed behind quality and freshness. In order for this form of food transport to experience growth among market users, more uncompromising strategies and regulations will have to be embraced and enacted.Food transportation is an industry that has fully adapted to the cold chain and can, despite the problems with air transport, be considered the most resilient, particularly since a large majority of food products have a better tolerance to temporary variations of transport temperatures. As a result, small errors can be compounded without the concern of irreversible damage. For instance, for the transportation of produces, for every hour of delay in the pre-cooling of shipments, an equivalent one day loss of shelf life must be accounted. The usageof refrigerated containers has particularly helped, since they account for more than 50% of all the refrigerated cargo transported in the world. Source loading can be an important factor extending the shelf life of a cold chain product since it is loaded in a reefer directly at the place of production without additional handling. For instance, source loading into a reefer can expand the shelf life of chilled meat by about 25 days (from 30-35 days to 55-60 days) from conventional methods and thus considerably expand the market potential of the product.The efficiency and reliability of temperature controlled transportation has reached a point which allows the food industry to take advantage of global seasonable variations, meaning that during the winter the southern hemisphere can export perishable goods to the northern hemisphere while an opposite trade, generally of smaller scale, takes place during the summer. Countries such as Chile have substantially benefited from this and have developed an active agricultural and food transformation industry mainly servicing the North American market during the winter, but also with several niche markets such as wine. A similar issue concerns some African countries such as Kenya that have developed a fresh produce and flower industries catering the European market. The fast food industry is also an active user of cold chain logistics as every outlet can be considered as a factory, with dozens of workers with schedules and shifts, inventory management and the supply chain of components (many ofwhich are temperature sensitive), and which are assembly lines producing quality-controlled and high-volume products.。

专业答辩组组长:(签名)201 年月日前言人们对新鲜食材的喜爱,自古至今从来没有中断。
只是碍于当时的条件,只有皇室高官才能享受快马加鞭在驿站之间传递送去的食材。
随着冷藏技术的不断发展,满足人们的需求变得更为现实,冷链物流应运而生。
现代人们生活品质的提高,人们对食品质量的要求也越来越高,冷链物流业逐渐崭露出商机。
同时,冷鲜食品比一般食品对于物流的要求更高、更专业,这也给冷链物流业的发展带来了挑战。
我国冷链物流业面着很大的发展空间。
据了解,我国在“十二五”期间就对冷链物流制定了较高的发展目标,并对冷库、冷藏车等设备及冷链流通率、冷藏运输率等指标均有明确的规划。
近年来,我国的冷藏行业发展迅速,对冷链物流的要求也越来越高。
之前由于我国的冷链物流比国外起步晚、基础设施陈旧等等造成我国冷链物流发展缓慢。
冷链物流应该重视科技的作用,健康快速的发展。
我国的冷冻速冻行业发展迅速,冷链物流也随之得到迅速发展,但是我国的冷链物流还存在一些问题,在两会期间有人大代表就这些问题提出应该重点投资建设我国的冷链物流网,让人们的生活必需品的品质得到保障。
冷链物流运输相关文献综述
冷链物流运输相关文献综述(1)国外研究现状世界范围看,多个发达国家已经建立起了水运、铁路、公路、民航共同发展的综合冷链物流体系例如加拿大以五大湖地区为中心,由公路和铁路组成的跨越美加口岸的南北运输走廓,联系着美国和加拿大之间的贸易往来。
日本的冷链物流发展较早,相关研究也以技术研究为主。
在高新技术的带动下,目前日本的冷链物流发展较快,以水果的冷链物流运输为例,可以将坏果率控制在5%以内。
同时国外研究在信息技术促进冷链物流发展的领域内也多有体现。
M Lütjen(2013),认为强化第三方的喷码识别在冷链物流运输中的作用较大,可以从源头上及时识别冷链物流中的问题产品,达到追踪溯源的目的。
同时,这个作用是生产者自我喷码所不能达到的效果,必须由法定权威的第三方开展实施,才能保证冷链物流中产品运输质量。
Tamimi M (2020),认为冷链物流的发展,最主要的影响因素市场,冷链物流的建设者需要从市场找寻发展的动力,征求消费者关于冷链物流的发展建议,强化冷链物流的建设,深入满足消费者的需求。
(2)国内的研究现状目前,中国的冷链市场仍处于发展初期,许多方面尚不够完善,空运方式的高成本也并不为更多人所看好。
中国生鲜行业发展缓慢,很大程度上是受到了冷链运输的制约,高成本导致收益降低,阻碍了发展的速度。
李伟(2018)分析了中国冷链物流的发展状况,其中以海运、铁路运输与为主的冷链物流模式仍是目前冷链物流的重点,但是公路冷链物流的比例较低,同时铁路运输的运价较高,是制约我国冷链物流发展的瓶颈。
同时还有从技术方面进行分析和研究的文献。
总起来说,我国冷链物流技术发展较快,但是在部分环节仍然容易出现问题,例如容易出现制冷不冷,保全不全的问题,这些问题严重限制了我国冷链物流行业的发展。
张喜才(2019)在“中国农产品冷链物流经济特性、困境及对策研究”一文中认为“冷链不冷、断链等问题频繁发生”。
制约着我国冷链物流行业的发展。

冷链物流外文参考文献The Cold Chain and its LogisticsAuthors: Dr. Jean-Paul Rodrigue and Dr. Theo Notteboom 1. Overview While Globalization has made the relative distance between regionsof the world much smaller, the physical separation of these same regions is still a very important reality. The greater the physical separation, the more likely freight can be damaged in one of the complex transport operations involved. Some goods can be damaged by shocks while others can be damaged by undue temperature variations. For a range of goods labeled as perishables, particularly food, their quality degrades with time since they maintain chemical reactions which rate can be mostly mitigated with lower temperatures. It takes time and coordination to efficiently move a shipment and every delay can have negative consequences, notably if this cargo is perishable. To ensure that cargo does not become damaged or compromised throughout this process, businesses in the pharmaceutical, medical and food industries are increasingly relying on the cold chain technology.The cold chain refers to the transportation of temperature sensitive products along a supply chain through thermal and refrigerated packaging methods and the logistical planning to protect the integrity of these shipments.Specialization has led many companies to not only rely on major shipping service providers such as the United Parcel Service (UPS) andFEDEX, but also more focused industry specialists that have developed a niche logistical expertise around the shipping of temperature sensitive products. The potential to understand local rules, customs and environmental conditions as well as an estimation of the length and time of a distribution route make them an important factor in global trade. As a result, the logistics industry is experiencing a growing level of specialization and segmentation of cold chain shipping in several potential niche markets within global commodity chains. Whole new segments of the distribution industry have been very active in taking advantage of the dual development of the spatial extension of supply chains supported by globalization and the significant variety of goods in circulation. From an economic development perspective, the cold chain enables many developing countries to take part in the global perishable products market. From a geographical perspective, the cold chain has the following impacts:, Global. Specialization of agricultural functions permitting the transport of temperaturesensitive food products to distant markets. Enables the distribution of vaccines and otherpharmaceutical or biological products., Regional. Can support the specialization of functions and economies of scale, such asspecialized laboratories., Local. Timely distribution to the final consumer, namely grocery stores and restaurants. 2. Emergence of Cold Chain Logistics While global commodity chains are fairly modern expansions in the transportation industry, the refrigerated movement of temperature sensitive goods is a practice that dates back to 1797 when British fishermen used natural ice to preserve their fish stock piles. This process was also seen in the late 1800s for the movement of food from rural areas to urban consumption markets, namely dairy products. Cold storage was also a key component of food trade between colonial powers and their colonies. For example, in the late 1870s and early 1880s, France was starting to receive large shipments of frozen meat and mutton carcasses from South America, while Great Britain imported frozen beef from Australia and pork and other meat from New Zealand. By 1910,600,000 tons of frozen meat was being brought into Great Britain alone. The first reefer ship for the banana trade was introduced in 1903 by the United Food Company. This enabled the banana to move from an exoticfruit that had a small market because it arrived in markets too ripe, to one of the world's most consumed fruit. The temperature controlled movement of pharmaceuticals and medical supplies is a much more modern transit option than the shipping of refrigerated or frozen food. Since the 1950s, logistical third party companies began to emerge andinstitute new methods for successfully transporting these global commodities. Before their emergence, cold chain processes weremostly managed in house by the manufacturer. In the United States, Food and Drug Administration restrictions and accountability measures over the stability of the cold chain incited many of these companies to rely on specialty couriers rather than completely overhauling their supply chain facilities. A specialized industry was thus born. The value of the cold chain in the preservation of expensive vaccines and medical supplies was only beginning to be recognized when these logistical providers started to appear. As awareness began to grow, so did the need for efficient management of the cold chain. The reliance on the cold chain continues to gain importance. Within the pharmaceutical industry for instance, the testing, production and movement of drugs relies heavily on controlled and uncompromised transfer of shipments. A large portion of the pharmaceutical products that move along the cold chain are in the experiment or developmental phase. Clinical research andtrials is a major part of the industry that costs millions of dollars, but one that also experiences a failure rate of around 80%. According to the Healthcare Distribution Management Association, of the close to 200 billion dollars in pharmaceutical distribution, about 10% are drugs that are temperature sensitive. This makes the cold chain responsible for transporting a near 20 billion dollar investment. If these shipments should experience any unanticipated exposure to variant temperature levels, they run the risk of becoming ineffective or even harmful to patients.Temperature control in the shipment of foodstuffs is a component of the industry that has continued to rise in necessity with international trade. As a growing number of countries focus their export economy around food and produce production, the need to keep these products fresh for extended periods of time has gained in importance. Increasing income levels create a change in diet with amongst others a growing appetite for fresh fruit and higher value foodstuffs such as meat and fish. Persons with higher socioeconomic status and with more economic means are more likely to consume vegetables and fruit, particularly fresh, not only in higher quantities but also in greater variety. Consumers with increasing purchase power have become preoccupied with healthy eating, therefore producers and retailers have responded with an array of exotic fresh fruits originating from around the world.Any major grocery store around the world is likely to carry tangerines from South Africa, apples from New Zealand, bananas from Costa Rica and asparagus from Mexico. Thus, a cold chain industry has emerged to service these commodity chains. In 2002, an estimated 1200 billion dollars' worth of food was transported by a fleet of 400,000 refrigerated containers (Reefers). Alone, the United States imports about 30% of its fruits and vegetables and 20% of its food exports can be considered perishables. The uncompromised quality and safety of this food is often taken for granted, despite being the main reason behind the ability to sell the food. The cold chain serves the function of keeping food fresh for extended periods and eliminating doubts over thequality of the food products. In all the supply chains it is concerned with, cold chain logistics favor higher levels of integration since maintaining temperature integrity requires a higher level of control of all the processes involved. It may even incite third party logistics providers to acquire elements of the supply chain where time and other performance factors are the most important, even farming. This may involve the acquisition of produce farms (e.g. oranges) to insure supply reliability.3. Providing Temperature Controlled EnvironmentsThe success of industries that rely on the cold chain comes down to knowing how to ship a product with temperature control adapted to the shipping circumstances. Different products require different temperature level maintenance to ensure their integrity throughout the travel process. For instance, the most common temperature standards are "banana" (13 ?C), "chill" (2 ?C), "frozen" (-18 ?C) and "deep frozen" (-29 ?C). Staying within this temperature is vital to the integrity of a shipment along the supply chain and for perishables it enables to insure and optimal shelf life. Any divergence can result in irrevocable and expensive damage; a product can simply lose any market or useful value.Being able to ensure that a shipment will remain within a temperature range for an extended period of time comes down largely to the type of container that is used and the refrigeration method. Factors such as duration of transit, the size of the shipment and the ambient or outside temperatures experienced are important in deciding what type ofpackaging is required. They can range from small insulated boxes that require dry ice or gel packs, rollingcontainers, to a 53 footer reefer which has its own powered refrigeration unit. The major coldchain technologies involve:, Dry ice. Solid carbon dioxide, is about -80?C and is capable of keeping a shipment frozen for an extended period of time. It is particularly used for the shipping of pharmaceuticals, dangerous goods and foodstuffs. Dry ice does not melt, instead it sublimates when it comes in contact with air., Gel packs. Large shares of pharmaceutical and medicinal shipments are classified as chilled products, which means they must be stored in a temperature range between 2 and 8?C. The common method to provide this temperature is to use gel packs, or packages that contain phase changing substances that can go from solid to liquid and vice versa to control an environment. Depending on the shipping requirements, these packs can either start off in a frozen or refrigerated state. Along the transit process they melt to liquids, while at the same time capturing escaping energy and maintaining an internal temperature. , Eutectic plates. The principle is similar to gel packs. Instead, plates are filled with a liquid and can be reused many times., Liquid nitrogen. An especially cold substance, of about -196?C, used to keep packages frozen over a long period of time. Mainly used totransport biological cargo such as tissues and organs. It is consideredas an hazardous substance for the purpose of transportation., Quilts. Insulated pieces that are placed over or around freight to act as buffer in temperature variations and to maintain the temperature relatively constant. Thus, frozen freight will remain frozen for alonger time period, often long enough not to justify the usage of more expensive refrigeration devices. Quilts can also be used to keep temperature sensitive freight at room temperature while outsideconditions can substantially vary (e.g. during the summer or the winter)., Reefers. Generic name for a temperature controlled container,which can be a van, small truck, a semi or a standard ISO container. These containers, which are insulated, arespecially designed to allow temperature controlled air circulation maintained by anattached and independent refrigeration plant. The term increasingly apply to refrigeratedforty foot ISO containers.Perishable or temperature sensitive items are carried inrefrigerated containers (called "reefers"), that account for a growing share of the refrigerated cargo being transported around the world.While in 1980 33% of the refrigerated transport capacity in maritime shipping was containerized, this share rapidly climbed to 47% in 1990, 68% in 2000 and 90% in 2010. About 1.69 million TEUs of reefers werebeing used by 2009. All reefers are painted white to increase the albedo(share of the incident light being reflected; high albedo implies less solar energy absorbed by the surface) with the dominant size being 40 high-cube footers (45R1 being the size and type code). For instance alow albedo container can have its internal temperature increase to 50 ?C when the external temperature reaches 25 ?C on a sunny day while a high albedo container see its internal temperature increase to only 38 ?C under the same conditions.The refrigeration unit of a reefer requires an electric power source during transportation and at a container yard. Regular containerships have 10 to 20% of their slots adapted to carry reefers, with some ships having up to 25% of their slots being dedicated. It is important to underline that the refrigeration units are designed to maintain the temperature within a prefixed range, not to cool it down. This implies that the shipment must be brought to the required temperature before being loaded into a reefer, which requires specialized warehousing and loading / unloading facilities. A new generation of reefers is coming online, which are equipped with an array of sensors monitoringeffectively the temperature and shutting the cooling plant when unnecessary. This enables to improve the reliability of temperature control and well as extend the autonomy of the reefer.The growth of the intermodal transportation of reefers hasincreasingly required transport terminals, namely ports, to dedicate a part of their storage yards to reefers. This accounts between 1% to 5%of the total terminal capacity, but can be higher for transshipment hubs.The stacking requirements simply involve having an adjacent power outlet, but the task is more labor intensive as each container must be plugged and unplugged manually and thetemperature to be monitored regularly as it is the responsibility of the terminal operator to insure that the reefers keep their temperature within preset ranges. This may also forbid the usage of an overhead gantry crane implying that the reefer stacking area can be serviced by different equipment. Even if reefers involve higher terminal costs, they are very profitable due to the high value commodities they transport.4. The Setting and Organization of Cold ChainsMoving a shipment across the supply chain without suffering any setbacks or temperature anomalies requires the establishment of a comprehensive logistical process the maintain the shipment integrity. This process concerns several phases ranging from the preparation of the shipments to final verification of the integrity of the shipment at the delivery point:, Shipment preparation. When a temperature sensitive product isbeing moved, it is vitalto first assess its characteristics. A key issue concerns the temperature conditioning of theshipment, which should be already at the desired temperature. Cold chain devices arecommonly designed to keep a temperature constant, but not to bring a shipment to thistemperature, so they would be unable to perform adequately if a shipment is not preparedand conditioned. Other concerns include the destination of the shipment and the weatherconditions for those regions, such as if the shipment will be exposed to extreme cold orheat along the transport route., Modal choice. Several key factors play into how the shipment will be moved. Distancebetween the origin and the final destination (which often includes a set of intermediarylocations), the size and weight of the shipment, the required exterior temperatureenvironment and any time restrictions of the product all effect the available transportationoptions. Short distances can be handled with a van or truck, while a longer trip mayrequire an airplane or a container ship., Custom procedures. If the freight crosses boundaries, custom procedures can becomevery important, since cold chain products tend to be time sensitive and more subject toinspection than regular freight (e.g. pharmaceuticals and biological samples). Thedifficulty of this task differs depending on the nation (or economic bloc) and the gatewaysince there are variations in procedures and delays., The "Last Mile". The last stage is the actual delivery of the shipment to its destination,which in logistics is often known as the “last mile”. Key considerations when arranging afinal delivery concern not only the destination, but the timing. Trucks and vans, theprimary modes of transportation for this stage, must meet the specifications necessary totransfer the cold chain shipment. Also important is the final transfer of the shipment intothe storage facilities as there is potential for a breach of integrity., Integrity and quality assurance. After the shipment has been delivered, anytemperature recording devices or known temperature anomalies must be recorded andmade known. This is the step of the logistical process that creates trust and accountability,particularly if liability for a damaged shipment is incurred. If problems or anomalies thatcompromise a shipment do occur, an effort must be made to identify the source and findcorrective actions.Therefore, the setting and operation of cold chains is dependent on the concerned supply chains since each cargo unit to be carried has different requirements in terms of demand, load integrity and transport integrity.5. Food TransportationThere is a variety of methods for the transport of food productswith the banana accounting for the world's most significant commodity transported in the food cold chain with 20% of all seaborne reefers trade. Land, sea and air modes all have different structures for keeping food fresh throughout the transport chain. Innovations in packaging,fruit and vegetable coatings, bioengineering (controlled ripening), and other techniques reducing the deterioration of food products have helped shippers extend the reach of perishable products. For food products such as fruits and vegetables, time has a direct impact on their shelf life and therefore on the potential revenue a consignment may generate. Concomitantly, new transport technologies have permitted the shipment of perishable products over longer distances. For instance, improved roads and intermodal connections along the African coast reduced transport time for food to European markets from 10 days to 4 days.Certain domestic or transnational supply chains may only require one transportation mode, but many times ground shipments are one link in a combination of transport modes. This makes intermodal transfer critical for the cold chain. Intermodal shipments typically use either 20 or 40 footers refrigerated containers that are capable of holding up to 26 tons of food. The container makes loading and unloading periods shorter and less susceptible to experiencing damage. The environments in these containers are currently controlled electronically by either plugging into a generator or power source on the ship or truck, but early food shipments would cycle air from stores of wet or dry ice to keep the food refrigerated. The efficiency of cold chain logistics permitted the consolidation of cold storage facilities. Moving away from ice refrigeration has allowed for much greater distances to be traveled and has greatly increased the size of the global food market, enabling many developing countries to capture new opportunities. Another efficient mode for transporting foodstuffs is air travel. While this is a preferred form of travel for highly perishable and valuable goods due to its ability to move much faster over longer distances, it does lack the environment control and transfer ease of the ground and sea transports. Also, during the flight the cargo is stored in a 15?C – 20?C environment, but close to 80% of the time the package is exposed to exterior weather while waiting to be loaded onto the plane or being moved to and from the airfield. This is troubling considering the value of the food and the importance placed behind quality and freshness. Inorder for this form of food transport to experience growth among market users, more uncompromising strategies and regulations will have to be embraced and enacted. Food transportation is an industry that has fully adapted to the cold chain and can, despite the problems with air transport, be considered the most resilient, particularly since a large majority of food products have a better tolerance to temporaryvariations of transport temperatures. As a result, small errors can be compounded without the concern of irreversible damage. For instance, for the transportation of produces, for every hour of delay in the pre-cooling of shipments, an equivalent one day loss of shelf life must be accounted. The usage of refrigerated containers has particularly helped, since they account for more than 50% of allthe refrigerated cargo transported in the world. Source loading can be an important factor extending the shelf life of a cold chain product since it is loaded in a reefer directly at the place of production without additional handling. For instance, source loading into a reefer can expand the shelf life of chilled meat by about 25 days (from 30-35 days to 55-60 days) from conventional methods and thus considerably expand the market potential of the product. The efficiency andreliability of temperature controlled transportation has reached a point which allows the food industry to take advantage of global seasonable variations, meaning that during the winter the southern hemisphere can export perishable goods to the northern hemisphere while an opposite trade, generally of smaller scale, takes place during the summer.Countries such as Chile have substantially benefited from this and have developed an active agricultural and food transformation industry mainly servicing the North American market during the winter, but also with several niche markets such as wine. A similar issue concerns some African countries such as Kenya that have developed a fresh produce and flower industries catering the European market. The fast food industry is also an active user of cold chain logistics as every outlet can be considered as a factory, with dozens of workers with schedules and shifts, inventory management and the supply chain of components (many of which are temperature sensitive), and which are assembly lines producing quality-controlled and high-volume products.。
