Definition of Logistics


物流的定义



There are many different definitions for logistics in different countries and periods,


and they have always changed with the development of society. Some definitions are


typical.


The Council of Logistics Management defined the logistics in 1992 as the process of


planning, implementing, and controlling the efficient, effective flow and storage of


goods, services, and related information from point of origin to point of consumption


for the purpose of conforming to customer requirements.


有物流在不同国家和时期的许多不同的定义,他们总是改变了社会的发展。一些定义


是典型的。



物流管理理事会确定的物流于


1992


年,规划的过程中,实施和控制从起点的快速,高


效流动和储存的货物,服务和相关信息消费点,以满足客户的目的要求。



And the definition from the MIT Center for Transportation & Logistics is that logistics


involves “managing the flow of items, informat


ion, cash and ideas through the


coordination of supply chain processes and through the strategic addition of place,


period and pattern values.”



In practice, the terms “logistics” and “supply chain management” are now used


interchangeably. Actually logistics and the Supply Chain are equivalent terms, so the


Institute of Logistics (1998) gave the following definitions:


并从麻省理工学院为中心的运输与物 流的定义是,物流涉及到“项目管理,信息,资


金和想法,通过供应链流程的协调,并通 过战略性补充的地方,周期和模式值的


流。”



在实践中,术语“物流”和“供应链管理”正在互换使用。实际上物流和供应链是等

价的条件,所以物流研究所(


1998


)给出了如下定义:



Logistics is the time related positioning of resource or the strategic management of


the total supply chain. The supply chain is a sequence of events intended to satisfy a


customer. It can include procurement, manufacture, distribution, and waste disposal,


t


ogether with associated transport, storage and information technology1.”



In some developed countries, the productivity had risen and the total quantities of


products became saturation in the early 1990s, also there were many products which


can not be distributed because of the competition. It was difficult to develop the


technique as well. People had to find a new way to solve the problems. They intend


to expand the market and reduce the cost through the improvement of distribution.


It was the initial concept of logistics.


物流是资源的时间与定位或整个供应链 的战略管理。供应链是旨在满足顾客的事件序


列。它可以包括采购,制造,分销,以及废 物处理,以及相关的运输,仓储和信息技

The earliest concept of logistics came from Ar


ch W. Shaw’s ?Some Problems in


Market Distribution? (1915). They called it “Physical Distribution” (PD) at that time.


The definition focused mainly on the distribution.


In the late 1980s people have already had a general and deep comprehension about


logistics. PD as a definition could not characterize the whole frame of logistics. The


logistics included not only the physical distribution but also production logistics,


returned logistics, material reuse and the contents like that. Logistics as a suitable


definition occurred instead of PD.

Logistics Engineering means the management process of choosing the best scheme


under the guidance of theories about system engineering and planning, managing,


controlling the system with lowest cost, high efficiency and good customer service


for the purpose of improving economy profits of the society and enterprises2. In this


definition we also integrate the logistics and the flow of information as a system and

Unit 2 Inventory Management

库存管理



Inventory decisions are high risk and high impact for supply chain management.


Inventory committed to support future sales drives a number of anticipatory supply


chain activities. Without a proper inventory assortment lost sales and customer


dissatisfaction may occur. Likewise, inventory planning is critical to manufacturing.


Material or component shortages can shut down a manufacturing line or force


modification of a production schedule, which creates added cost and potential


finished goods shortages. Just as shortages can disrupt planned marketing and


manufacturing operations, inventory overstocks also create operating problems.


Overstocks increase cost and reduce profitability as a result of added warehousing,


working capital, insurance, taxes, and obsolescence. Management of inventory


resources requires an understanding of the principles, cost, impact, and dynamics.

Inventory Risk


存货风险



Inventory management is risky, and risk varies depending upon a f


irm’s position in


the distribution channel. The typical measures of inventory commitment are time


duration, depth, and width of commitment.


For a manufacturer, inventory risk is long term. The manufacturer’s inventory


commitment starts with raw material and component parts, includes work-in- process,


and ends with finished goods. In addition, finished goods are often positioned in


warehouses in anticipation of customer demand. In some situations, manufacturers


are required to consign inventory to customer facilities. In effect, this practice shifts


all inventory risk to the manufacturer. Although a manufacturer typically has a


narrower product line than a retailer or wholesaler, the manufacturer's inventory


commitment is deep and of long duration.


库存管理是有风险的,而且风险取决于在分销渠道坚 定的立场各不相同。存货承诺的


典型措施是持续时间,深度和宽度的承诺。



对于一个制造商,库存风险是长期的。制造商的库存方面的承诺始于原材料 和零部


件,包括工作进程,并与制成品结束。此外,成品通常放置在仓库的预期客户的需


求。在某些情况下,生产商须委托库存,以客户的设施。实际上,这种做法转移所有


库存风险,制造商。虽然制造商通常具有更窄的产品线比零售商或批发商,制造商的


库存方面的承诺深,持续时间长和。

A wholesaler purchases large quantities from manufacturers and sells smaller


quantities to retailers. The economic justification of a wholesaler is the capability to


provide retail customers with assorted merchandise from different manufacturers in


specific quantifies. When products are seasonal, the wholesaler may be required to


take an inventory position far in advance of the selling season, thus increasing depth


and duration of risk. One of the greatest challenges of wholesaling is product-line


expansion to the point where the width of inventory risk approaches that of the


retailer while depth and duration of risk remain characteristic of traditional


wholesaling1. In recent years, retail clientele have also forced a substantial increase


in depth and duration by shifting inventory responsibility back to wholesalers.

的特征点。近年来 ,零售客户也被迫在深度和持续


时间大幅增加通过转移库存责任推回给批发商

< p>


For a retailer, inventory management is about buying and selling velocity. The


retailer purchases a wide variety of products and assumes a substantial risk in the


marketing process. Retailer inventory risk can be viewed as wide but not deep. Due


to the high cost of store location, retailers place prime emphasis on inventory


turnover and direct product profitability. Inventory turnover is a measure of


inventory velocity and is calculated as the ratio of annual sales divided by average


inventory.


对于零售商的库存管理是关于购买和 销售速度。零售商购买了各种各样的产品,并假

If a business plans to operate at more than one level of the distribution channel, it


must be prepared to assume related inventory risk. For example, the food chain that


operates a regional warehouse assumes risk related to the wholesaler operation over


and above the normal retail operations. To the extent that an enterprise becomes


vertically integrated, inventory must be managed at all levels of the supply chain.

Inventory Functionality

From an inventory perspective, the ideal situation would be a response capability to


manufacture products to customer specification. While a zero-inventory


manufacturing/ distribution system is typically not attainable, it is important to


remember that each dollar invested is a trade-off with an alternative use of assets


that may provide a better return

Inventory is a major asset that should provide return for the capital invested. The


return on inventory investments is the marginal profit on sales that would not occur


without inventory. Accounting experts have long recognized that measuring the true


cost and benefits of inventory on the corporate profit-and-loss is difficult. Lack of


measurement sophistication makes it difficult to evaluate the trade-offs among


service levels, operating efficiencies, and inventory levels. While aggregate inventory


levels have been decreased, many enterprises still carry an average inventory that


exceeds their basic requirements. This generalization can be understood better


through a review of the four prime functions of inventory.

These four functions require inventory investment to achieve managerial operating


objectives. Given a specific manufacturing/marketing strategy, inventories planned

At the minimum level, inventory invested to achieve geographical specialization and


decoupling can only be modified by changes in facility location and operational


processes of the enterprise. The minimum level of inventory required to balance


supply and demand depends on the difficult task of estimating seasonal


requirements. With accumulated experience over a number of seasonal periods, the


inventory required to achieve marginal sales during periods of high demand can be


projected fairly well. A seasonal inventory plan can be formulated based upon this


experience.

Inventories committed to safety stocks represent the greatest potential for improved


logistical performance. These commitments are operational in nature and can be


adjusted rapidly in the event of an error or policy change. A variety of techniques are


available to assist management in planning safety stock commitments. The focus in


the balance of this chapter is on a thorough analysis of safety stock relationships and


policy formulation.

Inventory management is a major element of logistical strategy that must be


integrated to meet service objectives. While one strategy to achieve a high service


level is to increase inventory, other alternative approaches are the use of fast


transportation and collaboration with customers and service providers to reduce


uncertainty.

Inventory Planning


库存计划



Key parameters and procedures, namely, when to order, how much to order, and


inventory control, guide inventory planning. The when-to- order is determined by the


demand and performance average and variation. The how much to order is


determined by the order quantity. Inventory control determines the process for


monitoring inventory status.

Determining When to Order


确定何时订购



The reorder point defines when a replenishment shipment should be initiated. A


reorder point can be specified in terms of units or days' supply. This discussion


focuses on determining reorder points under conditions of demand and performance


cycle certainty.


The basic reorder point formula is:


R=D×


T


where R = Reorder point in units;


D= Average daily demand in units; and


T = Average performance cycle length in days.


订货点时,定义一个补充货物应启动。再订购点可以以单位或天的供应量来指定。本

An alternative form is to define reorder point in terms of days of supply. For the


above example, the days of supply reorder point are 10 days.


The use of reorder point formulations implies that the replenishment shipment will


arrive as scheduled. When uncertainty exists in either demand or performance cycle


length, safety stock is required. When safety stock is necessary to accommodate


uncertainty, the reorder point formula is:


R =D×


T+SS

Determining How Much to Ordervv


确定订购多少



Lot sizing balances inventory carrying cost with the cost of ordering. The key to


understanding the relationship is to remember that average inventory is equal to


one-half the order quantity. Therefore, the greater the order quantity is, the larger


the average inventory is and, consequently, the greater the annual carrying cost is.


However, the larger the order quantity, the fewer orders required per planning


period and, consequently, the lower the total ordering cost. Lot quantity formulations


identify the precise quantities at which the annual combined total inventory carrying


and ordering cost is lowest for a given sales volume. Figure 6.1 illustrates the basic


relationships. The point at which the sum of ordering and carrying cost is minimized


represents the lowest total cost. Simply stated, the objectives are to identify the


ordering quantity that minimizes the total inventory carrying and ordering cost.

EOQ




The EOQ is the replenishment practice that minimizes the combined inventory


carrying and ordering cost. Identification of such a quantity assumes that demand


and costs are relatively stable throughout the year. Since EOQ is calculated on an


individual product basis, the basic formulation does not consider the impact of joint


ordering of products.


The most efficient method for calculating EOQ is mathematical. For example a


policy dilemma regarding whether to order 100, 200, or 600 units was discussed.


The answer can be found by calculating the applicable EOQ for the situation. Table


6.1 contains the necessary information.

To benefit from the most economical purchase arrangement, orders should be placed


in the quantity of 300 units rather than 100, 200, or 600. An EOQ of 300 implies that


additional inventory in the form of base stock has been introduced into the system.


While the EOQ model determines the optimal replenishment quantity, it does require


some rather stringent assumptions. The major assumptions of the simple EOQ model

The constraints imposed by some of these assumptions can be overcome


through computational extensions; however, the EOQ concept illustrates the


importance of the trade-offs associated with inventory carrying and


replenishment ordering cost.


Relationships involving the inventory performance cycle, inventory cost, and


economic order formulations are useful for guiding inventory planning. First,


the EOQ is found at the point where annualized order cost and inventory


carrying cost are equal. Second, average base inventory equals one-half


order quantity. Third, the value of the inventory unit, all other things being


equal, will have a direct relationship with replenishment order frequency. In


effect, the higher the product value, the more frequently it will be ordered.


一些这些假设所施加的约束可以通过计算扩展来克服,但是,

第二,平均基本存货等于一半订货量。三,库存单位的价值,所有其他的事情都是

Inventory Management Policies


库存管理策略



Inventory management is the process that implements inventory policy. The


reactive or pull inventory approach uses customer demand to pull product


through the distribution channel. An alternative philosophy is a planning


approach that proactively allocates inventory based on forecasted demand and

Inventory Control


库存控制



Inventory control is the managerial procedure for implementing an


inventory policy. The accountability aspect of control measures units on


hand at a specific location and tracks additions and deletions. Accountability


and tracking can be performed on a manual or computerized basis.


Inventory control defines how often inventory levels are reviewed to

Summary


总结



Inventory typically represents the second largest component of logistics cost next


to transportation. The risks associated with holding inventory increase as


products move down the supply chain closer to the customer because the


potential of having the product in the wrong place or form increases and costs


have been incurred to move the product down the channel3. Further, the cost of


carrying inventory is significantly influenced by the cost of the capital tied up in


the inventory. Geographic specialization, decoupling, supply/demand balancing,

While there is substantial interest in reducing overall supply chain inventory,


inventory does add value and can result in lower overall supply chain costs with


appropriate trade-offs.

Historically, the process of acquiring these needed inputs has been


considered somewhat of a nuisance, at least as compared to other activities


within the firm. Purchasing was regarded as a clerical or low-level managerial


activity charged with responsibility to execute and process orders initiated


elsewhere in the organization1. The role of purchasing was to obtain the


desired resource at the lowest possible purchase price from a supplier. This


traditional view of purchasing has changed substantially in the past two


decades. The modem focus on supply chain management with its emphasis


on relationship between buyers and sellers has elevates purchasing to a


higher, strategic-level activity. This strategic role is differentiated from the


traditional through the term procurement, although in practice many people


use the terms purchasing and procurement interchangeable.

Procurement Perspectives


采购展望



The evolving focus on procurement as a key capability in organizations has


stimulated a new perspective regarding its role in supply chain management.


The emphasis has shifted from adversarial, transaction-focused negotiation


with suppliers to ensuring that the firm is positioned to implement its


manufacturing and marketing strategies with support from its supply base. In


particular, considerable focus is placed on ensuring supply, inventory


minimization, quality improvement, supplier development, and lowest total


cost of ownership.

Procurement Strategies


采购策略



Effective procurement strategy to support supply chain management


concepts requires a much closer working relationship between buyers and


sellers than was traditionally practiced. Specially, three strategies have


emerged: volume consolidation, supplier operational integration, and value


management. Each of these strategies requires an increasing degree of


interaction between supply chain partners; thus, they may not be considered


as distinct and separate but rather as evolutionary stages of development.
