In respond to the demand of an open, fair, transparent, and efficient environment for procurement, many governments have incorporated the use of internet in their procurement systems with online procurement (e-procurement). Given the different policies and laws which have to be complied with, the practice of government e-procurement system varies from one country to another. Thus, experiences in running e-procurement will vary as well. The achievements and obstacles of one country's experience will be a constructive reference for other countries in establishing e-procurement system. In this regard, government e-procurement system practices in two Southeast Asia countries i.e., Thailand and Indonesia particularly in public works are consecutively presented and finally compared in this paper. The government of Thailand has applied Online Auctions (e-Auctions) as the national procurement practice since 2005 and performed the e-Auctions in two types: Reverse Auction and Sealed Bid Auction. Contrary to the common practice of e-procurement, the Thai government, with some rationales, runs the bid documents obtaining manually as well as qualification and technical documents submission and holding the e-Auctions at bidding office. Whereas Indonesian government runs Online Sealed Bid Bidding (e-Procurement) and most of the bidding stages are performed electronically except bid evaluation for both technical and financial. The advantages and drawbacks of these two e-procurement practices are discussed as well as improvements that have to be made for successful of e-procurement.

It is very necessary to find how to develop international government procurement by analyzing functions and roles of information providing circumstance and existing total international government procurement information system. In addition, it would require to draw up a way of improving current international government procurement information system based on the problems of existing system. In this study, we analyze the current status of Korean international government procurement information system and give an idea of mutual cooperating with DGMARKET, a good example of international government procurement information system. As a practical method, cooperating with DGMARKET by building each countries' gateway will be very helpful in cost saving and providing information. It will also complement the limitation of Korean system's one way service. But supplying only international government procurement information is insufficient in realization of e-trade in international goverment procurement market. To settle these problems, treating international government procurement as a same field of trade and giving political support and incentive to company which hopes to participate international goverment procurement are absolutely needed.

The purpose of this study would like to investigate the critical success factors of the e-procurement which means on-line purchase of goods and services for organizations. This action represents one of the largest expense items in a firm's cost structure. In order to draw CSFs of e-procurement system, we have surveyed questionnaire to the related firms. The basic variables used in this survey are taken from many precedent researches in relation to the e-procurement. On the other hand, the research data is collected from companies which had used the MRO e-marketplace. Through factor analysis of those data, four-factor resulted as follows: (1) factor one suggests the rationalization of the firm's management of its suppliers; (2) factor two calls for redesigning affected business processes and influencing end-user/employee procurement-related behaviors; (3) factor three refers to carefully orchestrating an e-procurement technology planning process with one's suppliers and using intelligence in designing the software and mining the data it produces; and (4) factor four relates to selecting an e-procurement solution and/or simultaneously participating in a number of electronic environments supporting e-procurement. In conclusion, these four factors are regarded as critical success factors for the application of e-procurement system and then suppliers should take care the effective planning of e-procurement structure.

Nowadays many enterprises build e-procurement systems. An e-procurement is a Web-based procurement process and its functionalities are considered important in the B2B e-commerce. Buyers should select competent suppliers for a successful e-procurement. Therefore, this study proposes a method using the analytic hierarchy process(AHP) for building a Web-based supplier selection system. In detail, the purpose of this study is (1) to review methods previously used when buyers selecting suppliers and to extract important selection criteria： (2) to explain extended AHP method adopted by this study among supplier selection methods： (3) to describe the supplier selection steps using extended AHP ： and (4) to propose a decision support system embedding the methodology described above. The proposed system comprises of three phase： first phase is to evaluate suppliers on enterprise level： second phase to evaluate them on each transaction level： third phase to post-evaluate them.

본 논문은 국내 자동차산업을 대상으로 개발된 응용시스템으로, UML(Unified Modeling Language)을 이용한 XML(eXtensible Markup Language)기반의 안전한 전자조달(E-Procurement) 시스템을 제안하고 있다. 컴포넌트 개발기법인 UML 방법론의 활용으로 자동차산업의 구매업무 Workflow가 분석되었으며, XML 기반의 EDI(Electronic Data Interchange)와 전자서명 기능을 구현함으로써 기업간 구매업무를 자동화하는 효율적인 E-Procurement 시스템 프로토타입이 구현되었다. 또한 본 논문은 기존 정보공학방법론에서 한계로 지적되던 S/W의 재사용성과 Life Cycle의 위험을 줄인 컴포넌트 개발기법을 활용하고, 기업내 Legacy 시스템인 ERP와의 연동을 가능하게 하였다. 본 시스템은 기존 시스템이 제공하지 못하는 워크플로우(workflow)분석 및 설계, 컴포넌트 개발, 기업내부 시스템과의 연동, 그리고 전자문서의 무결성과 인증을 위한 XML 전자서명을 적용하는 해법을 제안하고 있다.

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.

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.

본 연구의 목적은 전자구매시스템의 도입을 통해 구매성과기대에 미치는 영향을 파악하고자 하는 것이다. 선행연구의 고찰을 통해 다음의 가설이 설정되었다. H1 : 근무호텔의 특성(호텔등급, 객실 수, 경영형태, 직원 수)에 따라 전자구매시스템도입에 대한 필요성지각에는 차이가 있을 것이다; H2 : 전자구매 시스템 도입에 대한 필요성 지각은 식자재, 음자재, 객실소모성 및 청소용품, 시설 관련 일반자재 구매에 대한 성과 기대에 유의한 영향을 미칠 것이다; H2-1, H2-1, H2-3, H2-4 : 전자구매 시스템 도입에 대한 필요성 지각이 식자재, 음자재, 객실소모성 및 청소용품, 시설 관련 일반자재 구매성과기대에 미치는 영향에 있어서 직급과 직무는 조절변수역할을 할 것이다. 결과적으로 전자구매시스템도입에 대한 필요성 지각은 구매기대성과에 비례하는 것으로 나타났으며, 직급과 직무의 조절변수역할에 대한 검증은 부분채택 되었다.

국내 공공전자조달은 국내외에 우수성을 인정받고 있다. 하지만 수요기관이 발주 시 조달업체가 관련 공고를 일일이 확인하거나, 전체 조달공고현황을 한눈에 파악하기에는 어려움이 있다. 그에 따라 본 논문에서는 효과적인 전자조달시스템의 활용을 위해 빅데이터 기술인 HDFS와 아파치 스파크 기술, 협업필터링 기술을 이용하여, 조달공고 추천서비스와 조달공고 계약 트렌드 분석 서비스 구현을 통한 전자조달공고 분석지원 시스템을 개발하였다. 조달공고 추천서비스는 조달업체의 특성과 성격에 맞는 공고를 추천함에 따라 조달업체가 일일이 공고를 검색하는 수고를 덜어 줄 수 있으며, 조달 공고 계약 트렌드 분석 서비스는 조달 공고/계약 정보를 시각화하여 조달업체와 수요기관에게 전자조달의 분석정보를 한눈에 확인할 수 있도록 구현하였다.
