List and define the four major drivers of supply chain performance.Answer: Facilities are the places in the supply chain network whereproduct is stored, assembled, or fabricated. The two major types offacilities are production sites and storage sites.Inventory is all raw materials, work in process, and finished goodswithin a supply chain. Inventory is an important supply chain driverbecause changing inventory policies can dramatically alter the supply chain’s efficiency and responsiveness.Transportation entails moving inventory from point to point in thesupply chain. Transportation can take the form of many combinations of modes and routes.Information consists of data and analysis concerning facilities,inventory, transportation, and customers throughout the supply chain.Information is potentially the biggest driver of performance in thesupply chain as it directly affects each of the other drivers.Difficulty: Moderate2. Explain the supply chain decision-making framework and the role of thefour major drivers.Answer: The goal of a supply chain strategy is to strike the balancebetween responsiveness and efficiency, resulting in a strategic fit with the competitive strategy. To reach this goal, a company uses the foursupply chain drivers discussed earlier. For each of the individualdrivers, supply chain managers must make a trade-off between efficiency and responsiveness. The combined impact of these four drivers thendetermines the responsiveness and efficiency of the entire supply chain.Most companies begin with a competitive strategy and then decide whattheir supply chain strategy ought to be. The supply chain strategydetermines how the supply chain should perform with respect toefficiency and responsiveness. The supply chain must then use the supply chain drivers to reach the performance level the supply chain strategydictates.Difficulty: Moderate3. Explain the basic trade-off between responsiveness and efficiency foreach of the major drivers of supply chain performance.Answer: The fundamental trade-off when making facilities decisions isbetween the cost of the number, location, and type of facilities(efficiency) and the level of responsiveness that these facilitiesprovide the company’s customers.The fundamental trade-off when making inventory decisions is betweenresponsiveness and efficiency. Increasing inventory will generally make the supply chain more responsive to the customer. This choice, however, comes at a cost as the added inventory decreases efficiency. Therefore,a supply chain manager can use inventory as one of the drivers forreaching the level of responsiveness and efficiency the competitivestrategy targets.The fundamental trade-off for transportation is between the cost oftransporting a given product (efficiency) and the speed with which that product is transported (responsiveness). The transportation choiceinfluences other drivers such as inventory and facilities. When supplychain managers think about making transportation decisions, they framethe decision in terms of this trade-off.Good information systems can help a firm improve both its responsiveness and efficiency. The information driver is used to improve theperformance of other drivers and the use of information is based on the strategic position the other drivers support. Accurate information canhelp a firm improve efficiency by decreasing inventory andtransportation costs. Accurate information can improve responsiveness by helping a supply chain better match supply and demand.Difficulty: Moderate4. Explain the role of each of the major drivers of supply chainperformance.Answer: Facilities are the where of the supply chain if we think ofinventory as what is being passed along the supply chain andtransportation as how it is passed along. They are the locations to orfrom which the inventory is transported. Within a facility, inventory is either processed or transformed into another state (manufacturing) or it is stored before being shipped to the next stage (warehousing).Inventory exists in the supply chain because of a mismatch betweensupply and demand. An important role that inventory plays in the supplychain is to increase the amount of demand that can be satisfied byhaving product ready and available when the customer wants it. Anothersignificant role inventory plays is to reduce cost by exploiting anyeconomies of scale that may exist during both production anddistribution. Inventory is spread throughout the supply chain from rawmaterials to work in process to finished goods that suppliers,manufacturers, distributors, and retailers hold.Inventory is a major source of cost in a supply chain and it has a hugeimpact on responsiveness. The location and quantity of inventory canmove the supply chain from one end of the responsiveness spectrum to the other.Inventory also has a significant impact on the material flow time in asupply chain. Material flow time is the time that elapses between thepoint at which Another important area where inventory has a significantimpact is throughput.Inventory and flow time are synonymous in a supply chain. Managersshould use actions that lower the amount of inventory needed withoutincreasing cost or reducing responsiveness, because reduced flow timecan be a significant advantage in a supply chain.Transportation moves product between different stages in a supply chain.Like the other supply chain drivers, transportation has a large impacton both responsiveness and efficiency. Faster transportation, whether in the form of different modes of transportation or different amounts being transported, allows a supply chain to be more responsive but reduces its efficiency. The type of transportation a company uses also affects theinventory and facility locations in the supply chain.Information could be overlooked as a major supply chain driver becauseit does not have a physical presence. Information, however, deeplyaffects every part of the supply chain. Its impact is easy tounderestimate as information affects a supply chain in many differentways. Information serves as the connection between the supply chain’svarious stages, allowing them to coordinate and bring about many of thebenefits of maximizing total supply chain profitability. Information is also crucial to the daily operations of each stage in a supply chain. For instance, a production scheduling system uses information on demand to create a schedule that allows a factory to produce the right products in an efficient manner. A warehouse management system uses information to create visibility of the warehouse’s inventory. The company can then use this information to determine whether new orders can be filled.Difficulty: Hard5. Explain the role of each of the major drivers of supply chainperformance in the competitive strategy.Answer: Facilities and their corresponding capacities to perform theirfunctions are a key driver of supply chain performance in terms ofresponsiveness and efficiency. For example, companies can gain economies of scale when a product is manufactured or stored in only one location;this centralization increases efficiency. The cost reduction, however,comes at the expense of responsiveness, as many of a company’scustomers may be located far from the production facility. The oppositeis also true. Locating facilities close to customers increases thenumber of facilities needed and consequently reduces efficiency. If thecustomer demands and is willing to pay for the responsiveness thathaving numerous facilities adds, however, then this facilities decisionhelps meet the company’s competitive strategy goals.Inventory plays a significant role in a supply chain’s ability tosupport a firm’s competitive strategy. If a firm’s competitivestrategy requires a very high level of responsiveness, a company can use inventory to achieve this responsiveness by locating large amounts ofinventory close to the customer. Conversely, a company can also useinventory to make itself more efficient by reducing inventory throughcentralized stocking. The latter strategy would support a competitivestrategy of being a low-cost producer. The trade-off implicit in theinventory driver is between the responsiveness that results from moreinventory and the efficiency that results from less inventory.The role of transportation in a company’s competitive strategy figuresprominently when the company is considering the target customer’s needs.If a firm’s competitive strategy targets a customer that demands a very high level of responsiveness, and that customer is willing to pay forthis responsiveness, then a firm can use transportation as one driverfor making the supply chain more responsive. The opposite is true aswell. If a company’s competitive strategy targets customers whose maindecision criterion is price, then the company can use transportation tolower the cost of the product at the expense of responsiveness. As acompany may use both inventory and transportation to increaseresponsiveness or efficiency, the optimal decision for the company often means finding the right balance between the two.。

There is a close connection between the design and management of supplychain flows and the success of a supply chain.Answer: TrueDifficulty: EasyEssay/Problems1. Explain the 3 decision phases (categories) that must be made in a successfulsupply chain.Answer: The 3 decision phases that occur within a supply chain are supply chain strategy (or design), supply chain planningand supply chain operation. Decisions relate to the flow of information, product and funds. The difference between categories depends upon the frequency of each decision and the time frame over which it has an impact. During the supply chain strategy phase, a companydetermines what the chain’s configurations will be, how resources will beallocated, and what processes each stage will perform. This will establish thestructure of the supply chain for several years. Supply chain planning deals withdecisions with a time frame from 3 months up to a year. The planning phasemust work within the constraints established in the strategy phase. Planningdecisions include which markets to supply from which locations, subcontractingof manufacturing, inventory policies and timing and size of marketing promotions.The supply chain operation phase operates on a weekly or daily time horizon and deals with decisions concerning individual customer orders.Difficulty: Hard答：决策的3阶段发生在一个供应链的供应链战略（或设计），供应链与供应链运作。

Discuss the role of safety inventory in the supply chain and the trade-offsinvolved.Answer: The primary role of safety inventory is providing product availability forcustomers when demand and supply are uncertain. The trade-off that a supplychain manager must consider when planning safety inventory involve productavailability and inventory holding costs. On one hand, raising the level of safetyinventory increases product availability and thus the margin captured fromcustomer purchases. On the other hand, raising the level of safety inventoryincreases inventory holding costs. This issue is particularly significant inindustries where product life cycles are short and demand is very volatile.Carrying excessive inventory can help counter demand volatility but can reallyhurt if new products come on the market and demand for the product in inventory dries up. The inventory on hand then becomes worthless.In tod ay’s business environment, firms experience great pressure to improveproduct availability while increasing product variety through customization. As aresult, markets have become increasingly heterogeneous and demand forindividual products is very unstable and difficult to forecast. Both the increasedvariety and the increased pressure for availability push firmsto increase the level of safety inventory they hold.At the same time, product life cycles have shrunk. This increases the risk to firms of carrying too much inventory. Thus, a key to the success of any supply chain isto figure out ways to decrease the level of safety inventory carried without hurting the level of product availability.Difficulty: Hard2. Discuss the various measures of product availability.Answer: Product availability reflects a firm’s ability to fill a customer order out ofavailable inventory. A stockout results if a customer order arrives when product is not available. There are several ways to measure product availability. Allavailability measures are defined on average over a given time frame, which can range from hours to a year.Product fill rate (fr) is the fraction of product demand that is satisfied from product in inventory. It is equivalent to the probability that product demand is suppliedfrom available inventory.Order fill rate is the fraction of orders that are filled from available inventory. In amulti-product scenario, an order is filled from inventory only if all products in theorder can be supplied from the available inventory. Order fill rates tend to belower than product fill rates because all products must be in stock for an order to be filled.Cycle service level(CSL) is the fraction of replenishment cycles that end with all the customer demand being met. A replenishment cycle is the interval betweentwo successive replenishment deliveries. The CSL is equal to the probability ofnot having a stockout in a replenishment cycle. Observe that a CSL of 60 percent will typically result in a much higher fill rate.The distinction between product fill rate and order fill rate is not significant in asingle product situation. When a firm is selling multiple products, however, thisdifference may be significant. For example, if most orders include 10 or moredifferent products that are to be shipped, an out-of-stock situation of one product results in the order not being filled from stock. The firm in this case may have apoor order fill rate even though it has good product fill rates. Tracking order fillrates is important when customers place a high value on the entire order beingfilled simultaneously.Difficulty: Moderate3. Describe the two types of ordering policies and the impact each has on safetyinventory.Answer: A replenishment policy consists of decisions regarding when to reorderand how much to reorder. These decisions determine the cycle and safetyinventories along with the fr and the CSL. There are several forms thatreplenishment policies may take. We restrict attention to two instances:1. Continuous review: Inventory is continuously tracked and an order for a lotsize Q is placed when the inventory declines to the reorder point (ROP). The time between orders may fluctuate given variable demand. When using a continuousreview policy, a manager has to account only for the uncertainty of demandduring the lead time (L).2. Periodic review: Inventory status is checked at regular periodic intervals andan order is placed to raise the inventory level to a specified threshold. In thiscase, the time between orders is fixed. The size of each order, however, canfluctuate given variable demand. Periodic review replenishment policies requiremore safety inventory than continuous review policies for the same lead time andlevel of product availability, because the safety inventory has to cover fordemand uncertainty over the lead time and the review interval (L + T). Periodicreview policies are simpler to implement for retailers because they do not require that the retailer have the capability of continuously monitoring inventory. Giventhat higher uncertainty must be accounted for, periodic review policies will requirea higher level of safety inventory.Difficulty: Moderate4. Explain the impact of supplier lead time on safety。

Decisions relate to the flow of information, product and funds. The difference betweencategories depends upon the frequency of each decision and the time frame over which it has an impact. During the supply chain strategy phase, a companydetermines what the chain ' s configurations will be, how resources will beallocated, and what processes each stage will perform. This will establish thestructure of the supply chain for several years. Supply chain planning deals withdecisions with a time frame from 3 months up to a year. The planning phase must work within the constraints established in the strategy phase. Planning decisionsinclude which markets to supply from which locations, subcontracting ofmanufacturing, inventory policies and timing and size of marketing promotions.The supply chain operation phase operates on a weekly or daily time horizon and deals with decisions concerning individual customer orders.Difficulty: Hard2. Describe the cycle view of the processes within a supply chain.Answer: The cycle view divides the supply chain into a series of 4 cycles between the 5 different stages of a supply chain. The cycles are the customer order cycle,replenishment cycle, manufacturing cycle and procurement cycle. The customerorder cycle occurs at the customer/retailer interface and includes all processesdirectly involved in receiving and filling the customer. The replenishment cycleoccurs at the retailer/distributor interface and includes all processes involved inreplenishing retailer inventory. The manufacturing cycle typically occurs at thedistributor/manufacturer (or retailer/manufacturer) interface and includes allprocesses involved in replenishing distributor (or retailer) inventory. Theprocurement cycle occurs at the manufacturer/supplier interface and includes allprocesses necessary to ensure that the materials are available for manufacturing according to schedule.Difficulty: Moderate3. Explain the push/pull view of the processes within a supply chain.Answer: The push/pull view of the supply chain divides supply chain processesinto two categories based on whether they are executed in response to acustomer order or in anticipation of customer orders. Pull processes are initiatedin response to a customer order. Push processes are initiated and performed inanticipation of customer orders. The push/pull boundary separates pushprocesses from pull processes. This view is very useful when consideringstrategic decisions relating to supply chain design, because it forces a moreglobal consideration of supply chain processes as they relate to the customer.Difficulty: Moderate4. Explain the three macro processes within a supply chain.Answer: All processes within a supply chain can be classified into three macroprocesses which are Customer Relationship Management (CRM), Internal Supply Chain Management (ISCM), and Supplier Relationship Management (SRM).Customer Relationship Management (CRM) includes all processes that focus onthe interface between the firm and its customers such as marketing, sales, callcenter management and order management. Internal Supply Chain Management (ISCM) includes all processes that are internal to the firm such as preparation ofdemand and supply plans, preparation of inventory management policies, orderfulfillment and planning of capacity. Supplier Relationship Management (SRM)includes all processes that focus on the interface between a firm and its suppliers such as evaluation and selection of suppliers, negotiation of supply terms andcommunication regarding new products and orders.Difficulty: Moderate5. Explain why supply chain flows are important.Answer: Supply chain flows are important, because there is a close connectionbetween the design and management of supply chain flows (product, information, and cash) and the success of a supply chain. The success of many companiescan be directly traced to the design and management of an appropriate supplychain. The failure of many businesses can be linked directly to their inability toeffectively design and manage supply chain flows.Difficulty: Moderate。

List and define the four major drivers of supply chain performance.Answer: Facilities are the places in the supply chain network whereproduct is stored, assembled, or fabricated. The two major types offacilities are production sites and storage sites.Inventory is all raw materials, work in process, and finished goodswithin a supply chain. Inventory is an important supply chain driverbecause changing inventory policies can dramatically alter the supply chain’s efficiency and responsiveness. Transportation entails moving inventory from point to point in thesupply chain. Transportation can take the form of many combinations of modes and routes.Information consists of data and analysis concerning facilities,inventory, transportation, and customers throughout the supply chain.Information is potentially the biggest driver of performance in thesupply chain as it directly affects each of the other drivers.Difficulty: Moderate2. Explain the supply chain decision-making framework and the role of thefour major drivers.Answer: The goal of a supply chain strategy is to strike the balancebetween responsiveness and efficiency, resulting in a strategic fit with the competitive strategy. To reach this goal, a company uses the foursupply chain drivers discussed earlier. For each of the individualdrivers, supply chain managers must make a trade-off between efficiency and responsiveness. The combined impact of these four drivers thendetermines the responsiveness and efficiency of the entire supply chain.Most companies begin with a competitive strategy and then decide whattheir supply chain strategy ought to be. The supply chain strategydetermines how the supply chain should perform with respect toefficiency and responsiveness. The supply chain must then use the supply chain drivers to reach the performance level the supply chain strategydictates.Difficulty: Moderate3. Explain the basic trade-off between responsiveness and efficiency foreach of the major drivers of supply chain performance.Answer: The fundamental trade-off when making facilities decisions isbetween the cost of the number, location, and type of facilities(efficiency) and the level of responsiveness that these facilitiesprovide the company’s customers.The fundamental trade-off when making inventory decisions is betweenresponsiveness and efficiency. Increasing inventory will generally make the supply chain more responsive to the customer. This choice, however, comes at a cost as the added inventory decreases efficiency. Therefore,a supply chain manager can use inventory as one of the drivers forreaching the level of responsiveness and efficiency the competitivestrategy targets.The fundamental trade-off for transportation is between the cost oftransporting a given product (efficiency) and the speed with which that product is transported (responsiveness). The transportation choiceinfluences other drivers such as inventory and facilities. When supplychain managers think about making transportation decisions, they framethe decision in terms of this trade-off.Good information systems can help a firm improve both its responsiveness and efficiency. The information driver is used to improve theperformance of other drivers and the use of information is based on the strategic position the other drivers support. Accurate information canhelp a firm improve efficiency by decreasing inventory andtransportation costs. Accurate information can improve responsiveness by helping a supply chain better match supply and demand.。

Explain the 3 decision phases (categories) that must be made in a successfulsupply chain.Answer: The 3 decision phases that occur within a supply chain are supply chain strategy (or design), supply chain planning and supply chain operation. Decisions relate to the flow of information, product and funds. The difference betweencategories depends upon the frequency of each decision and the time frame over which it has an impact. During the supply chain strategy phase, a companydetermines what the chain’s configurations will be, how resources will beallocated, and what processes each stage will perform. This will establish thestructure of the supply chain for several years. Supply chain planning deals withdecisions with a time frame from 3 months up to a year. The planning phasemust work within the constraints established in the strategy phase. Planningdecisions include which markets to supply from which locations, subcontractingof manufacturing, inventory policies and timing and size of marketing promotions.The supply chain operation phase operates on a weekly or daily time horizon and deals with decisions concerning individual customer orders.Difficulty: Hard2. Describe the cycle view of the processes within a supply chain.Answer: The cycle view divides the supply chain into a series of 4 cyclesbetween the 5 different stages of a supply chain. The cycles are the customerorder cycle, replenishment cycle, manufacturing cycle and procurement cycle.The customer order cycle occurs at the customer/retailer interface and includesall processes directly involved in receiving and filling the customer. Thereplenishment cycle occurs at the retailer/distributor interface and includes allprocesses involved in replenishing retailer inventory. The manufacturing cycletypically occurs at the distributor/manufacturer (or retailer/manufacturer) interface and includes all processes involved in replenishing distributor (or retailer)inventory. The procurement cycle occurs at the manufacturer/supplier interfaceand includes all processes necessary to ensure that the materials are availablefor manufacturing according to schedule.Difficulty: Moderate3. Explain the push/pull view of the processes within a supply chain.Answer: The push/pull view of the supply chain divides supply chain processesinto two categories based on whether they are executed in response to acustomer order or in anticipation of customer orders. Pull processes are initiatedin response to a customer order. Push processes are initiated and performed inanticipation of customer orders. The push/pull boundary separates pushprocesses from pull processes. This view is very useful when consideringstrategic decisions relating to supply chain design, because it forces a moreglobal consideration of supply chain processes as they relate to the customer.Difficulty: Moderate4. Explain the three macro processes within a supply chain.Answer: All processes within a supply chain can be classified into three macroprocesses which are Customer Relationship Management (CRM), InternalSupply Chain Management (ISCM), and Supplier Relationship Management(SRM). Customer Relationship Management (CRM) includes all processes thatfocus on the interface between the firm and its customers such as marketing,sales, call center management and order management. Internal Supply ChainManagement (ISCM) includes all processes that are internal to the firm such aspreparation of demand and supply plans, preparation of inventory managementpolicies, order fulfillment and planning of capacity. Supplier RelationshipManagement (SRM) includes all processes that focus on the interface between a firm and its suppliers such as evaluation and selection of suppliers, negotiation of supply terms and communication regarding new products and orders.Difficulty: Moderate5. Explain why supply chain flows are important.Answer: Supply chain flows are important, because there is a close connectionbetween the design and management of supply chain flows (product, information, and cash) and the success of a supply chain. The success of many companiescan be directly traced to the design and management of an appropriate supplychain. The failure of many businesses can be linked directly to their inability toeffectively design and manage supply chain flows.Difficulty: Moderate。
供应链设计与管理(第3版)课后答案,选译
》》》》》》》》》》》》供应链设计与管理——概念、战略与案例研究（第3版）《《《《《《《《《《《《《（选译）第一章1.纵向一体化的企业拥有、管理并运作所有相关的业务职能。
横向一体化的企业由一些独立运营的企业组成，公司总部提供品牌、指导和一般战略。
比较并对比这两种类型企业的供应链战略。
答：纵向一体化企业旨在加强公司各业务成分之间的互动，而且经常集中地管理它们。
这样的结构，可以更容易地通过中央决策除去供应链中的不同部分之间的冲突来实现系统的整体目标。
在横向一体化公司，协调公司内部各业务的供应链通常是没有效益的。
事实上，如果横向一体化企业中的每个企业都专注于它的核心功能，并以最佳状态运行，就可能达到总体的全局最优效果。
2.如果一个企业是完全纵向一体化的，有效供应链管理是否仍然重要？答：有效供应链管理对于完全纵向一体化的公司仍然重要。
在这样的组织结构,公司的不同部门负责不同业务,通常它们都有自己的内部目标,而这些目标有时是无关联的。
这可能是由于缺乏部门之间的沟通或高层的激励政策。
比如,如果只依据收益来评估销售部门, 只依据成本来评估制造部门,公司的总体利润就难以达到最大化。
有效的供应链管理在全局最优业务操作中仍是必要的。
3.考虑一个企业重新设计其物流网络。
为数不多的几个集中仓库的优点是什么？大量靠近最终用户的仓库的优点是什么？答：少数位于市中心的仓库，允许公司利用风险分担，以提高服务水平并降低库存水平和成本。
不过，对外运输成本通常较高，交货间隔期较长。
另一方面，企业可以通过建立更多的靠近最终用户的仓库，以减少对外运输成本和交货间隔期。
然而，这种类型的系统将会使总库存水平和成本增加、规模经济下降、仓储费用增加，并且可能增加对内运输费用。
4.考虑一个企业选择运输服务提供商。
使用卡车承运商的优点是什么？使用诸如UPS这样的包裹速递公司的优点是什么？答：企业对运输服务的选择在很大程度上取决于公司要运输的产品的类型和大小，库存和交付的策略，以及对灵活性的需求：1.如果是大量而稳定的从仓库到需求点（店）运送大件物品或小件物品，货车运输会更好。
