4、(SCM) rise is attributed to enterprises trying to eliminate production and inventory plans misleading as information slow transmission or errors. In 1990s, some of computer manufacturers such as HP, or P & G which product household appliances begin integrate information systems of down-upstream, hop

5、e to archieve purposes for rapid responsion to the demand of market and lower inventory by correct and rapid transmission, analysis and integration of information. Therefore, effective supply chain management is built on the basis of the high quality of information transmission and sharing, This wil

6、l rely heavily on information technology to provide reliable support.In todays age, information has become a key factor in the decision to the survival and development of enterprises, any business must face the issue of how to integrate information. Information is from both the vertical information

7、of the upstream and downstream firms and the horizontal information of the internal enterprise, as well as information of the macro level. How to transmit and share information, to coordinate economic behavior of the upstream and downstream enterprises and functional behavior of interal enterprise w

8、hich is the core questions supply chain management is to deal with. Compared with the individual enterprises, supply chain as an extended enterprise, shows own characteristics by its way of information flow and acquisition.2 The Characteristics of the Supply Chain Information Flow2.1 Wide coverage T

9、he information of the supply chain covers from all links of suppliers, manufacturers to distributors and then retailers in the supply chain. Information flow distinct into information flow of demand and supply, these are two different flows of information flow. When demand information (such as custo

10、mer orders, production planning, procurement, etc.) takes direction from the demand-side to the supply-side movement, it triggered logistics. Meanwhile supply information (such as storage lists, the inventory records for sales, deliver lists), together again along with materials for the direction of

11、 the supply chain from supply-side to demand-side movement. The information flow of individual enterprises mainly confined to the internal Invoicing records (see figure 1). 2.2 More access channels As businesses in the supply chain is a collaboration relationship and community interests, information

12、 of the supply chain have so many channels to obtain. demand information isnt only from the customers but also distributors and retailers; the supply Information is from various suppliers, These information flow and share in all enterprises through the supply chain information systems . For individu

13、al enterprises, as it havent formed the Community interests with upstream and downstream businesses, so it is totally dependent on own collection. 2.3 High-quality information Because of specialization, the quality of the supply chain was superior to the information of the single enterprise, For exa

14、mple, distributors and retailers can be specifically responsible for the collection of demond information, the suppliers will collect supply information, Product manufacturers collect information of products. 3 Information Technology and Supply Chain Management The development of information technol

15、ogy provides an effective support to supply chain management. About some issues how to thank of the impact of information technology on supply chain management, and how to use information technology in supply chain management, and so on, through studies, it basically can be summed up in three aspect

16、s : 3.1Enhance the sharing of information on the supply chain can effectively improve supply chain management When members of the supply chain based only on information from neighbor member of lower levels to make decision, the system will have a phenomenon of magnification of demand. The reason for

17、 this situation is not the irrational of all members, but rational decision-making in the actual circumstances of unclear information, included demand forecast in the unbalanced demand, increasing orders in the expected shortage, increasing EOQ for the fixed orders costs and effects of batch. The oc

18、currence of this phenomenon will have a negative impact on all members of the supply chain. To eliminate or contain this phenomenon, within the scope of the supply chain, we can take appropriate countermeasures, such as to strengthen information sharing, shorten the delay time, coordinate purchasing

19、 and simplify marketing behavior and so on. 3.2 The development of information technology enhances internal collaboration in the supply chain The development of information technology makes enterprises more accessible to use information technology to exchange and collaborate with other members of an

20、d supply chain, therefore the use costs relatively lower, so that enterprises can choose more supplies to get cheaper supply and services in the same level of information use costs. In other words, the relationship between enterprises and their suppliers will likely become unreliable and unstable, b

21、ut the number of suppliers which successful enterprises choose dont increase, but reduce. In fact, between enterprises and their suppliers and customers, it is necessary to establish a collaborative relationship that it has a clear requirement in the JIT, it just has not been given sufficient attent

22、ion. 3.3 The development of information technology can help to build a more perfect user demand model The end-user is an important component of the supply chain, the response situation to customer demand is a very important supply chain management evaluation. Better graspping the demands of users is

23、 the basis of supply chain management. Many articles used similar assumption for a variety of needs and distribution, but demand is random, its release is not as ideal as we generally assumed. Therefore, it is necessary to consider the demand forecast in the supply chain inventorycontrol problems, c

24、hoose different model according to different circumstances, establish an appropriate demand model. 4 Information Technology Support System of Supply Chain Management The establishment of the supply chain information systems needs a large number of information technology to support, we discuss inform

25、ation technology support system in the forming of supplychain management from the main areas of supply chain management. The main areas of supply chain management involved: products (services) design, manufacturing, marketing, customer service, logistics and so on. It is a synchronized, integrated p

26、roduction plan as a guide, through use different types of information technology to improve the performance in these areas (see figure 2). Information technology to support the supply chain can be divided into two levels.4.1 The first level The first level is component with technology of identificat

27、ion code, automatic identification and data collection technology, electronic data interchange technology, Information technology on the basis of Internet technology. 4.1.1 Technology of Identification Codes A unified information coding is the basis of the exchange and sharing of data among supply c

28、hain trading partners. Without it, automatic identification technology and electronic data interchange (EDI) can not be realized. Through standardization technology of information coding applied to the supply chain management system, it is realized that automated data collection in the activities of

29、 supply chain systems and exchange of data and sharing ofresources between systems. It can promote the efficient functioning of the supply chain activities. 4.1.2 Automatic Identification and Data Collection Technology Automatic identification and data collection (AIDC) has become the ideal technolo

30、gy of dealing with the logistics information in process to supply chain management. Through automatic identification technology, automatic data identification and data collection, it is ensured that High-speed and accurate data acquisition and real-time control in the links of supply chain. At prese

31、nt, in the supply chain management, the most commonly AIDC technology is barcode technology and radio frequency identification technology. Barcode technology can facilitate the timely capture the needs of the consumer, improve sales results, as take placeimmediately automatic retrieval of informatio

32、n in the activities. Barcode alternative keyboard input and improve the accuracy of data collection, the application of technology solve the bottleneck problems of the data entry and data collection. Radio Frequency Identification (RFID) technology is a relatively new automatic identification techno

33、logy. RFID technology can be characterized as non-contact identification (identification distance from a few centimeters to tens of meters), identification of high-speed moving objects, resistance of harsh environment, secrecy, it can also identify a number of identified targets, therefore widely us

54、传递、分析和整合，达到对市场的需求作快速反映并降低库存等目的。因此，有效的供应链管理是建立在高质量的信息传递和共享的基础上，而这又离不开信息技术提供的可靠支持。二、供应链信息流的特点在当今时代，信息成为了决定企业生存与发展的关键因素，任何一个企业都要面对如何集成信息的问题。信息既有来自上下游企业的纵向信息，也有来自企业内部的横向信息，还有来自宏观层面上的信息。如何传递和共享这些信息，将上下游企业的经济行为以及企业内部各部门、各岗位的职能行为协调起来，就是供应链管理所要处理的核心问题。与单个企业情况相比，供应链作为一种扩展企业，其信息流动和获取方式表现出自己的特色。1.覆盖范围广供应链中的信息流

55、覆盖了从供应商、制造商到分销商再到零售商等供应链中的所有环节。其信息流分为需求信息流和供应信息流，这是两个不同流向的信息流。当需求信息（如客户定单、生产计划、采购合同等）从需方向供方流动时，便引发物流。同时供应信息（如入库单、完工报告单、库存记录、可供销售量、提货发运单等）又同物料一起沿着供应链从供方向需方流动。单个企业下的信息流则主要限定在企业内部的进销存记录（见图）。图 供应链的信息流与单个企业的信息流2.获取途径多由于供应链中的企业是一种协作关系和利益共同体，因而供应链中的信息获取渠道众多，对于需求信息来说既有来自顾客也有来自分销商和零售商的；供应信息则来自于各供应商，这些信息通过供应链

56、信息系统而在所有的企业里流动与分享。对于单个企业情况来说，由于没有与上下游企业形成利益共同体，因此单个企业的信息获取则完全依赖于自己的收集。3.信息质量高由于存在专业分工，供应链中的信息质量要强于单个企业下的信息质量，例如,分销商和零售商可以专门负责收集需求信息，供应商则收集供应信息，生产厂商收集产品信息等。三、信息技术和供应链管理信息技术的发展为供应链管理提供了有效的支持。关于如何看待信息技术对供应链管理的影响，如何在供应链管理中利用信息技术等问题，通过研究，基本上可以归纳为三个方面：1.加强供应链中的信息共享可以有效地改进供应链的管理当供应链各成员只根据来自其相邻下级的信息进行决策时，系统

57、将产生需求放大现象，引起这种现象的原因并不是各成员的非理性，而是在实际信息不清楚情况下的理性决策，包括在非平稳需求情况下的需求预测、在预期缺货情况下增加定货量、在存在固定定货费用和批量效应时增大定货批量等。这种现象的发生将对供应链所有成员都产生负面影响。为了消除或抑制这种现象，可以在供应链范围内采取相应对策，如加强信息共享、缩短延迟时间、协调定货和简化促销行为等。2.信息技术的发展加强了供应链内部的协作信息技术的发展使得企业能够更方便地使用信息技术与供应链其他成员进行交流和协作，使用费用也因此相对降低，使企业能够在同样的信息使用费用水平上选择更多的供应商以获得更便宜的供应和服务。也就是说，企业

58、与其供应商之间的关系将有可能变得不可靠、不稳定，但实际上成功的企业选择的供应商数目并没有增加，而是减少了。其实，“企业与其供应商和用户之间必须建立一种协作关系”这一点在JIT 中已经有明确的要求，只是没有受到足够的重视。3.信息技术的发展可以帮助建立更完善的用户需求模型最终用户是供应链的一个重要组成部分，对用户需求的响应状况则是供应链管理的一个很重要的评价指标，因此能够较好地掌握用户需求是供应链管理的基础。目前很多文章都对需求及其分布采用了不同的近似假设，但实际上需求是随机的，其发布也不是如我们一般所假设的那样理想。因此，有必要在考虑供应链的库存控制问题中考虑对需求的预测，根据不同的情况选择不同的预测模型，建立恰当的需求模型。四、 供应链管理的信息技术支撑体系供应链信息系统的建立是需要大量信息技术来支撑的
