2、n management is built on the basis of the high quality of information transmission and sharing, This will rely heavily on information technology to provide reliable support. In this paper, against the characteristics of the supply chain information flow, discuss the impact of information technology
3、on supply chain management and support system which information technology form in the supply chain management. Key-Words: - Supply chain management; Information technology; Support System; Information flow; Supply chain; Information1 Introduction Supply Chain Management (SCM) rise is attributed to
4、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, hope to archieve purposes for r
5、apid 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 will rely heavily on informatio
6、n 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 of the upstream and downstre
7、am 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 which is the core questions s
8、upply 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 The information of the supply
9、 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 customer orders, production plann
10、ing, 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 the supply chain from suppl
11、y-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 of the supply chain have so
12、 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 individual enterprises, as it havent
13、 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 example, distributors and retai
14、lers 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 technology provides an effective su
15、pport 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 aspects :3.1Enhance the sharing of
16、 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 this situation is not the ir
17、rational 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 occurrence of this phenomenon w
18、ill 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 and simplify marketing behav
19、ior 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 and supply chain, therefore the
20、 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, but the number of suppliers wh
21、ich 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 attention. 3.3 The development of i
22、nformation 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 the basis of supply chain ma
23、nagement. 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, choose different model accordi
24、ng 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 information technology support syst
25、em 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 production plan as a guide, th
26、rough 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 identification code, automatic identific
27、ation 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 chain trading partners. Withou
28、t 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 supply chain systems and exc
29、hange 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 technology of dealing with the logist
30、ics 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 present, in the supply chain manag
31、ement, 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 information in the activities. Barcode
32、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 technology. 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 identifi
