This paper intends to suggest a XML-based secure E-Procurement system using Unified Modeling Language(UML), as an application system for domestic automobile industry. Applying UML methodology, which is Component-based Development (CBD), we analyzed the workflow on procurement operation of automobile industry and implemented a prototype of efficient E-Procurement system for automobile industry, by developing XML/EDI and XML signature. Also, on this paper, object-oriented CBD is employed to minimize the risk of life cycle and reuse software as mentioned to limitation of information engineering methodology. It enables the interoperability with ERP (Enterprise Resource Planning) as corporate legacy system. This system proposes a solution to apply analysis and design of workflow, component development, interoperability with corporate information system, and XML signature for integrity and authentication of electronic documents in other system so far.

This paper deals with the collaborative procurement process in a two-echelon supply chain that a manufacturing company and a contractor are connected through the information system. The real time information about inventory and production processing becomes available through this information system. We raise two issues related to the collaborative procurement process. First, we propose a VMI(Vendor-Managed Inventory) type of the procurement policy which focuses on the cost minimization for the total supply chain rather than individual companies. Second, based on the simulation study, we demonstrate that a collaborative procurement process is more cost-effective over classical procurement processes such as (Q, r). The result obtained in this paper can be applied to the quantitative evaluation of the cost saving effect when companies build the information sharing based, collaborative procurement system.

Because XML is a W3C standard and has characteristics like platform-independent, it has a critical role in e-commerce. Business rules and procedures should be standardized for efficient B2B integration. But a lot of companies has its own XML documents instead of standard documents. Therefore many organizations try to make standards for e-commerce based on framework. In this paper, n messaging system is designed and implemented. Client request service in a XML and server return response in XML in this system. So we can more easily and efficiently build e-Procurement system based on this XML messaging system.

The objective of this study is to show how much it could impact improvement expectation by adopting E-procurement system. Based on literature review, the following hypotheses were proposed: H1; The level of perception for adopting E-procurement system will be different by hotel's grade, the number of hotel rooms, types of Management, the number of employees. H2; Perception for adopting E-procurement system will influence improvement expectation of food material purchasing, beverage material purchasing, Room guest supplies & cleaning supplies, general material purchasing. H2-1, H2-2, H2-3, H2-4; Perception for adopting E-procurement system will differently influence improvement expectation of food material purchasing, beverage material purchasing, Room guest supplies & cleaning supplies, general material purchasing by job level and job performance. As a result, perception for adopting E-procurement system is in proportion to improvement expectation of purchasing and hypotheses related with job level and job performance which are moderating variables were accepted partially.

The researches on the factors of the procurement path choices have been increased since e-procurement, a new procurement fashion, is introduced. The previous researches have not much been interested in off-line procurement paths nor the domestic small and medium enterprises (SME). In this paper, the factors of the e-procurement and off-line procurement in the domestic SME are investigated. Some independent factors are derived based on the previous works, and among them the factors are discriminated by multinomial logit analysis.

The purpose of this study is how to apply to e-Commerce of parts procurement system in the Japanese Automobile Industry and examine the influence of that through the case studies of automobile makers. In the Japanese automobile industry, B2B e-Commerce of parts procurement system have a shifted from closed circuits through VAN to opened IP-VPN and eventually to the JNX of internet environment. The Japanese automobile industry depends mainly on IP-VPN and JNX, especially EDI on a one to one basis with parts procurement suppliers. As to the future direction of B2B e-Commerce of parts procurement in the Japanese automobile industry, many of commodity parts will be traded among established participants on internet websites owned by automobile maker groups. Finally, for improvement of B2B e-Commerce of parts procurement in the Japanese automobile industry I suggested that there are 'revitalize of e-Marketplace', 'improvement of IT and business process', 'extension of B2B e-Commerce among small and medium sized suppliers'.

This paper tried to find how the characteristics of purchasing items would have influence on the relational e-procurement. The characteristics of purchasing items include the importance and the complexity of purchasing items. In order to define these characteristics, this paper reviewed various literatures about purchasing strategies. The empirical analysis through the multi-nominal logistic regression shows that the importance of items has influence on relational e-procurement, while the complexity of purchasing process has little influence. And also, the relational e-procurement through EDI as a long term buying relationship is being converted toward the exchange through purchasing sites.
