1、Chapter1.Iroduction to Supply Chain Management1. 【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 cover

2、ing from buying, making, moving, warehousing to selling.3. 【What makes supply chain management difficult?】Supply chain strategies cannot be determined in isolation. They are directly affected by another chain that most organizations have, the development chain.It is challenging to design and operate

3、 a supply chain so that total systemwide costs are minimized, and systemwide service levels are maintained.Uncertainty and risk are inherent in every supply chain.4. 【Strategies for SCM】Global Optimization（全局优化）Managing Uncertainty（管理不确定性）5. 【Why is Global Optimization Hard?】The supply chain is a co

4、mplex network.Different facilities in the supply chain frequently have different, conflicting objectives.The supply chain is a dynamic system.System variations over time6. 【Why Is Uncertainty Hard to Deal With?】Matching supply and demand is a major challenge.Forecasting doesnt solve the problem.Inve

5、ntory and back-order levels typically fluctuate considerably across the supply chain, even when customer demand for specific products does not vary greatly.Demand is not the only source of uncertainty.Recent trends such as lean manufacturing, outsourcing, and offshoring that focus on reduction incre

6、ase risks significantly.7. 【The three principles of all forecasting techniques】Forecasting is always wrong.The longer the forecast horizon , the worse the forecast.Aggregate forecasts are more accurate.Chapter2. Inventory Management, Supply Contracts and Risk Pooling1. 【何时低（高）于平均需求】If the cost of no

7、t 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 quanti

8、ty is not necessarily equal to average, or forecast demand.3. 【Coefficient of variation】Coefficient of variation=Standard deviationAverage demandThe Standard deviation measures the absolute variability of customer demands, the coefficient of variation measures variability relative to average demand.

9、4. 【Risk Pooling: three critical points】Centralizing inventory control reduces both safety stock and average inventory level for the same service level.The higher the coefficient of variation, the greater the benefit obtained from centralized systems; that is, the greater the benefit from risk Pooli

10、ng.The benefits from risk Pooling depend on the behavior of demand from one market relative to demand from another.5. 【Forecasting Methods】Judgment methods（判断方法）Market research methods（市场研究方法） 为定性方法Time Series methods（时间序列方法）Causal methods（因果方法） 为定量方法。6. 【Inventory Managements controlling methods】Co

11、ntinuous review policy（持续检查策略）Periodic 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：The reorder point (s) has two components:a. To account for average demand during lead time: LT&#

12、215;AVGb. To account for deviations from average (we call this safety stock): z×STD×LTwhere z is chosen from statistical tables to ensure that the probability of stockouts during leadtime is 100%-SL. Since there is a fixed cost, we order more than up to the reorder point: Q=(2×K×

13、AVG)÷h The total order-up-to level is: S=Q+s 注：AVG = 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 (f

14、or 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】Assemble the opinion of expertsSales-force composite combines salespeoples estimates（销售人员汇集意见）Panels of experts internal, external, b

16、.Revenue-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.Global 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 th

17、e same organization. That is, the transfer of money between the parties is ignored and the unbiased decision maker will maximize supply chain profit.Quantity 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 q

18、uantity.Sales 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.Chapter3.

21、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?】Promotional sales：Forward buyingVolume and transportation discounts：BatchingInflated orders：IBM Aptiva orders increased by 2-

22、3 times when retailers thought that IBM would be out of stock over ChristmasDemand forecasting：Order-up-to points are modified as forecasts change orders increase more than forecastsLong cycle times：Long lead times magnify this effect4. 【Methods for Coping with the Bullwhip Effect】Reduce uncertainty
