Development of Web-EDI, System Structure Change of SCM, and Emulation Technology.

在本研究中，我们通过各种调查，思考Web-EDI的发展所引起的供应链系统结构变化与仿真技术的关系，目前为止，对于中小企业EDI的推广是有效的Web-EDI助力了SCM的传播。最近，互联网将WEB-EDI扩展到供应链之外的未指明的客户，并导致了e-Marketplace的形成。本研究以物流领域的货车配货系统作为电子市场的一个实例进行研究。通过对该系统的研究，思考了电子市场存在的各种问题，总体来说，类似货车配货系统的电子市场是以Web应用程序的形式开发的，包含了数据库。作为Windows系统服务器环境下Web应用程序构建技术的实例，本研究采用了ASP和ASP.NET技术。通过这些系统的功能和处理特点，考虑到这种技术在未来推广电子市场的可能性，到目前为止，供应链已经通过特定企业之间的合作伙伴关系连接起来。电子商城的推广有可能切断供应链，改变系统结构。然而，电子市场是一个由许多未指明的企业组成的市场。对于通过电子市场进行的供应和采购，需要与复杂的外部环境变化相对应的管理技术。有一种仿真技术就是这样的技术之一。本研究以物流领域的仿真器RaLC为例，对其功能进行了研究。并考虑了仿真技术引起SCM系统结构变化的可能性。

In this research, through various investigations, we would like to consider the relation between the system structure change of SCM that the development of Web-EDI would cause and the emulation technology.Up to now, Web-EDI that is effective for spread of EDI of the small and medium-sized enterprise has contributed to the spread of SCM. Recently, the Internet expands Web-EDI to customers who are unspecified outside the supply chain, and leads to the formation of e-Marketplace. Truck and Goods Matching System of logistics field is taken up as one example of e-marketplace in this research. Through investigating of this system, various problems of e-Marketplace are considered.In general, e-Marketplace like Truck and Goods Matching System is developed as a Web application including the data base. As an example of Web application construction technology in the Windows system server environment, ASP and ASP.NET are taken up in this research. Through the function and the processing characteristics of these systems, the possibility that such a technology will spread e-Marketplace in the future is considered.Up to now, the supply chain has been connected by the partnership between specific enterprises. The spread of e-Marketplace has the possibility of cutting the supply chain and changing the system structure. However, e-Marketplace is a market that consists of many and unspecified enterprises. For supply and procurement through e-Marketplace, the management techniques corresponding to the complex outside environment change are necessary. There is an emulation technology as one of such the techniques. In this research, the function of RaLC that is an emulator for logistics field is investigated as one example of the emulation technology. And the possibility that the emulation technology would cause the system structure change of SCM is considered.
