General Framework of Chain Store Information System base on Supply Chain Management Theory
Computer and Information Science
The purpose of this paper is to develop a chain store information system framework. This paper summarized information system requirements of chain store according to supply chain management theory firstly. It classified three types of information requirements. Then an information flow diagram was designed. This paper also projected concept structure, software structure and architecture of chain store information system. It proposed to use the distributing system and B/S computerizing module in
... ystem architecture. 152 subsystem. Of course, each subsystem is accredited to construct independent database which deposit special purpose data. Application software should support diversified management activities otherwise. Chain store information system formed by six subsystems which is illustrated in figure 4 Headquarters management information system: it not only supervises departments, but also collects distribute center data and local store data. Distribute center management information system: it implements static and dynamic management of inventory for example: commodities circulation, transportation and warehouse management. Branch management information system: it contains POS system and security system. Electronic order system (EOS): order data occur from wholesales and local store is transmited to headquarters, suppliers and manufacturers. Customer relationship management system: it is a process to compile information that increases understanding of how to manage an enterprise's relationships with it customers. CRM is a strategy that uses information technology to provide a integrated view of its customers. MAN network systems. MAN network system is a important bridge to connect headquarters, distribute centers, branches, suppliers and banks system that integrates the whole supply chain and reduces costs. With this connection, headquarters gains distribute centers' and branches' data and feedback to them betimes. System Architecture According to the hardware and software dispose, we can partition it into centralized system and distributing system. The Characteristics of Centralized System: Information facilities are concentrated in somewhere; it is safe and can be used efficiently; personal manager conveniently. But there are some disadvantages: it is weak for meeting an emergency and hard to maintain reliability. It is difficult for repairing, extending and upgrade. The Characteristics of Decentralized System: Information facilities are not disposed in a certain location. Information facilities are distributed in several location and they share information though network. The decentralized system not only can work together, but also can use local information to work independently. It has strong reliability and expansibility. Because the chain store information system has to Cross city, province, even states to operate, it is reasonable for undertake decentralized system. The prevalent B/S computerizing module is usually used in decentralized system. Without installing specify system software, customers can use ordinary browsers ( IE etc.) to inquiry data servers though WEB format. B/S is a special three layers' C/S computerizing module and his data transmission format also very multiplex, for example: multimedia etc. Universal communication protocol is independent from platform, so the whole system is very easy to development and maintenance. Its structure is shown in figure 5 MAN network is the key of chain store information system project planning duo to the distributing in different areas of headquarters, distribution centers, and filiales. Each filiale and distributer center develops his LAN network, then these LAN networks connect each other though decentralized network. Figure 6 is a vision of the whole network architecture.
