6.Within any supply chain are many systems, including various manufacturing, storage, transportation, and retail systems. 7.The materials, warehousing, and outbound logistics management also have lists of criteria. These include minimizing transportation costs by taking advantage of quantity discounts, minimizing inventory levels, and quickly replenishing stock. 8.Inventory appears in the supply chain in several forms: raw material inventory, Work-in-process (WIP) inventory, and finished product inventory. 9.In a distribution system, each stage or level (i.e., the warehouse or the retailers) is often referred to as an echelon. 10.In modern supply chains, information replaces inventory. 11.One of the most frequent suggestions for decreasing or eliminating the bullwhip effect is to centralize demand information; that is, by providing each stage of the supply chain with complete information on actual customer demand. 12.Lead time typically include the components: order lead times, and information lead times. 13.future customer demand is influenced by such issues as pricing, promotions, and the release of new products. 14.Information enables us to integrate the various stages in the supply chain. 15.Improved forecasting techniques and information systems reduce the other components of lead time. 16.product variety greatly increased the complexity of supply chain management. 17.Network configuration may involves issues relating to plant location, warehouse location, and retailer location. 18.Transportation rates are almost linear with distance but not with volume. 19. The echelon inventory at any stage or level of the system is equal to the inventory on hand at the echelon, plus all downstream inventory. 20.Informatioin changes the way supply chains can and should be effectively managed, and these changes may lead to lower inventories. 21. With longer lead times, a small change in the estimate of demand variability implies a significant change in safety stock, reorder level, and thus in order quantities

22. as transportation costs become more significant, retailers may order quantities that allow them to take advantage of transportation discounts. 23.the transportation costs are lowest when large quantities of items are transported between stages of the supply chain. 24.Supply Chain Management is a set of approached utilized to efficiently integrate suppliers, manufacturers, warehouses, and stores, so that merchandise is produced and distributed at the right quantities, to the right locations, and at the right time, in order to minimize systemwide costs while satisfying service level requirements. 25. logistics management is the process of planning, implementing and controlling the efficient, cost effective flow and storage of raw materials, in-process inventory, finished goods, and related information from point-of-origin to point-of-consumption for the purpose of conforming to customer requirements. 26.customers located in close proximity to each other are aggregated using a grid network or clustering technique. 27.Typically, three distinct outbound distribution strategies are utilized. They are： Direct shipment, Warehousing, Cross-docking. 28. Four types of strategic alliances are typically significant in supply chain management. Third-party logistics (3PL), retailer supplier partnerships (RSP), distributor integration (DI), manufacturer and supplier. 29．There are four ways to implement delayed differentiation. They are resequencing, commonality, modularity, standardization. 30. Key Issues in Supply Chain Management are Distribution Network, Configuration, Inventory Control, Supply Chain Integration and Strategic Partnering, Product Design, Information Technology and Decision-Support Systems, Customer Value. 31.The goal of effective inventory management in the supply chain is to have the correct inventory at the right place at the right time to minimize system costs while satisfying customer service requirements. 32.Inventory can appear in many places in the supply chain,and several forms:raw material inventory,work-in-process(WIP) inventory,finished product inventory. 33.The zero inventory ordering property can be observed by considering a policy which orders are placed and received when the inventory level is not zero. 34.Total cost at every cycle: Average inventory holding cost in a cycle: Q/2 Cycle time : T =Q/D 2 hTQ K +

Handing costs include labor and utility costs that are proportional to annual flow through the warehouse. 46.Fixed cost is typically proportional to warehouse size (capacity) but in a nonlinear way. 47.storage costs represent inventory holding costs,which are proportional to average positive inventory levels. 48.We argue that abundant information could help reduce variability in the supply chain,help suppliers make better forecasts ,enable lead time reductions,enables retailers to better serve their customers by offering tools for locating desired items,enables retailers to react and adapt to supply problems more rapidly. 49.An attractive policy used in practice by each stage of the supply chain is the periodic review policy where the inventory policy is characterized by a single parameter,the base-stock level. 50.The increase in variability is magnified with increasing lead time. 51.Forward buying ,implies that retailers purchase large quantities during distributor’s and manufactures’ discount and promotion time and order relatively small quantities at other time periods. 52.Inflated orders placed by retailers during shortage periods tend to magnify the bullwhip effect. 53.Base-Stock Level = L × AVG + z × STD× √L 54.Order up-to point = 55.OEM typically use an assemble-to-order strategy,while their contract manufacturers typically have to build capacity due to long lead time ,in advance to receiving orders from the OEM. 56.To determine the impact of centralized demand information on the bullwhip effect,we distinguish between two types of supply chains;one with centralized demand information and a t LSt  ˆ L + z
