Based on the levels of inter-organizational information flow and the degrees of suppliers' power, this study aims to develop a framework useful for classifying four types of the buyer's e-commerce strategies in manufacturing firms: e-marketplace, e-partnership, e-procurement and supplier's e-marketplace (e-distribution). We adopted a multi-methodological approach by mixing both qualitative and quantitative methods. After developing a framework, through the cases of Cisco, JAL, Toyota Motor, KIST, AMP, and 3M, this paper aims to confirm the actual existence of the four forms of e-commerce. The results from the cases supported the four types of e-commerce strategies in manufacturing firms. With the empirical data, we also demonstrated the configuration of the framework and the four types of e-commerce strategies, and identified the characteristics (i.e., size, age, actual adoption rate of the each type of e-commerce, and supply-chain performance) of the organizations employing each strategy.

This study performed an economic analysis and tested the viability of a public computerization project to create a comprehensive information system for public e-procurement for small and medium-sized businesses (SMBs). The study found that the estimated costs of the project included 4.3 billion won to build the system and 710 million won per year to maintain the system once it is built. The project's estimated total benefits amounted to 6.66 billion won per year, including 5.871 billion won per year in increased convenience for SMBs that use the system, 406 million won per year in benefits for public institutions, and 383 million won per year in benefits for the institution "A" to adopt the system. We used the contingent valuation method (CVM) to estimate the benefits to SMBs, which would be the main participants of the project. The survey found that the SMBs were willing to pay an average fee of 170,136 won. we conducted an economic analysis by applying a 5.5% social discount rate over an analysis period of 10 years and found a benefit-cost ratio of 5.02 and a net present value of 40.201 billion won, which indicated a very high economic viability of the project. The results of this study can be an important reference when deciding whether to pursue computerization projects in the public sector.

Supply chain management issues faced by a manufacturing company are considered in this paper. The supply chain consists of a manufacturing company and its suppliers. The manufacturer produces multiple products with inputs (e.g., raw materials) from the suppliers, but each product needs a different mix of these inputs. The market demand for the products is uncertain. We develop a mathematical model and algorithm, which can help the manufacturer to solve its procurement decision problem: how much of raw material to order from which supplier. The model incorporates such factors as market demand uncertainty, product's input requirement, supplier's as well as manufacturer's capacity, plus other costs comparable with those in a typical newsboy problem. Numerical examples are presented to see the interacting effects among critical parameters and variables.

The purpose of this study is to propose a new process model for architects and suppliers in AEC(Architectural, Engineering and Construction) industry, which comes from its utilization of a distributed database. Information used by participants of this process is not held in one singular application sewer, but in tile databases of multiple participants. This study addresses the problem of coping with dynamic information changes that architects face when designing with increasingly time-sensitive product information from multiple suppliers. It also describes the new distributed architecture for design representation, and outlines a corresponding process model to address the needs architectural designers during design and procurement phases. The feasibility of the process was tested in a prototype system that combines existing technologies, which allows for an objects transfer from the Web to the CAD application.

Information management of products and services in every industries is gaining importance for resource planning and maintenance. In this paper, we analyzed the information classification systems for railway industry. International and domestic classification systems, such as HS, UNSPSC, eCl@ss and ISIC, are reviewed; as a result this paper presents the findings and the various issues. We proposed to-be images in adopting and utilizing the classification systems. Using the integrative information classification systems could make efficient electronic procurement, supply chain management and e-Business of railway services.

사무자동화(OA)로부터 발전되어온 워크플로우의 기술은 현재는 e-비즈니스를 위한 인프라로서, 프로세스를 기반으로 다른 정보기술과 통합되고 나아가서는 기업통합을 가능하게 하는 비즈니스운영체제(BOS)로서 정보시스템에 있어서 그 역할이 매우 중요하다. 차세대 워크플로우 기술은 주요정보기술중의 하나인 웹 서비스 및 비즈니스프로세스관리(BPM) 기술 분야와 접목되고 기업응용통합(EAI) 기술과 융합되어 전자정부(e-Government), 전자상거래(e-Commerce), 전자병참(e-Logistics), 전자공급망관리(e-SCM), 전자구매시스템(e-Procurement) 등을 가능하게 하는 기업간 워크플로우 형태가 될 것이다.

Among EC areas. the B2B EC market is being spotlighted as an important interesting research area considering its size and the potential impact on companeies and the whole society. In comparison with private consumers in B2C EC. business buyers in B2B EC have to precisely keep track of the purchase records. and integrate them with the buyer's e-procurement system, which might have been implemented as a part of integrated ERP (Enterprise Resource Planning) systems. There are three approaches for such integration between ERP and e-marketplace in B2B EC; Two previous approaches are Inside-Out approach and Outside-In approach. And a newly, one is b-cart approach. In this paper, we try to survey these three approaches and make a comparison analysis. From this research. we identify that the b-cart approach is the most efficient framework in integrating ERP with e-marketplace in B2B EC.

국내 공공건설사업에서 건설기술용역 발주 및 입·낙찰 과정은 공정성과 투명성이 강조되어 계량적 항목 위주로 업체를 선정하는 방법을 주로 적용하여왔다. 이로 인해 업체의 기술경쟁력을 강화하고자 하는 동기부여가 미흡하였고, 기술력을 기반으로 하는 업체선정방식의 필요성은 지속적으로 제기되어 왔다. 본 연구에서는 미국 공공건설사업에서의 건설기술용역 서비스 발주 및 입·낙찰 관련 미국 정부의 방침, 제반 절차 및 규정 등을 관련법 및 관련시스템을 통해 분석하고, 국내 공공건설공사에서의 건설기술용역 발주 및 입·낙찰 및 나아가 계약관리 및 사후관리에 있어서 공정하고 효율적인 건설기술용역 관리에 시사 하는 바를 도출하였다. 주요 시사점으로는 자격요건 및 역량 기반의 업체 선정, 제출 서류의 단순화, 발주자의 역할 및 책임 강조, 중소업체에 대한 배려, 탈락자에 대한 배려, 사후평가 등의 측면에서 국내 건설기술용역 발주 및 입·낙찰에 고려될 수 있을 것으로 기대된다.

E-commerce represents the acquisition and sale, or the transmission of funds or data through an electronic platform. E-commerce is a paradigm shift that influences marketers and customers to improve current market processes. The significant challenges in e-commerce are the accuracy and performance factors during a business transaction, which has been substantially enhanced using Cloud Computing Techniques (CCT). The growth of e-commerce management has been increased due to massive internet penetration, and particularly small and emerging companies are increasingly using this alternative as a differentiated business model. E-commerce has significant environmental impacts and highly utilized in today's market scenario. Further, the replacement has not been thoroughly explored. Current research has been carried out to describe the e-commerce scenario to analyze market trends. This study further discusses the essential variables to the performance of market models for e-commerce. For example, e-procurement of products/services, electronic supply chain management, e-distribution and selling support (supplier connections, e-fulfilment) and online e-auctions (transactional) can represent important e-commerce capabilities, which can contribute to marketing strategy implementation effectiveness, resulting in higher export performance.
