Since the year of 2003, the overseas plant market has grown by an average of 6% per year. It is because of the increase of oil-money, economic growth of BRICs, and the result of heavy competition among the countries which demands a great amount of resources for the purpose of resource securing. Such a situation is expected to be continued for a while. The procurement is one of critical functions for successful completion of a plant project. For effective procurement, it is required to manage vendor's information efficiently. But most of the vendor management systems deal with simple general information and performance data about vendors. In this sense, this paper proposes a vendor management system which can be used within a decision-making system. The system uses existing DB and makes the close relationship with the vendors. This paper will also reduce risks and difficulties in the process of selecting the proper vendors and will increase efficiency of procurement process in electronic bidding between companies.

The national defense electronic procurement system is an information system supporting DAPA, services (Army, Navy and Air Force), and the procurement companies in the electronic bidding. It has contributed greatly to improving the efficiency of the national defense electronic procurement process by providing various information services based on inter-operation among the related parties. However the national defense electronic procurement system is expected to be upgraded to the next version in accord with rapidly evolving infrastructure based on high technology and increasing various communication channels. This paper investigates the satisfaction level of the system users and proposes directions for the next-generation procurement portal.

In Overseas case, most tunnels in under are or through the river are constructed with shield TBM and the manufacturer orders of related equipment suitable for the project are mode. Accordingly, the client provides the specifications required for the equipment manufacture. In addition, TBM equipment has been operated by those who have completed the expert training program, which for minimizing the risk of equipment operation in construction field corresponding to the mechanized construction. However, in Korea, such a system related to above the program and specifications has not yet been built, which is causing a lot of difficulties in construction field. Therefore, this study investigated the differences in bidding guides provided by mechanized construction in domestic and abroad, and the professional education programs for expert training being conducted from overseas. Futhermore, we will propose the guidelines of essential equipment specification contained in domestic bidding and provide the necessary manual for the professional education program for TBM as the mechanized construction method.

In this research, a case study for cooperative learning practiced in a design class for environmental engineering was presented. Designing a treatment facility for urban diffuse pollution was a main problem given to the participants. Turn-key system for civil works were simulated throughout class works. Twenty five students were grouped into four virtual companies and assigned own position from chairperson to workers. Each group competed throughout establishing design concept regarding order, expense calculation, process distribution, actual calculation. Best design with lowest bidding won the first place. For evaluating class effectiveness, one student from each group were monitored thorough semester. Participants were improved for their understanding about company establishment, turn-key system management, awareness about personal management, and presentation skills. Tension of the class was effectively elevated as well.

Full system of turnkey deliberation committee in 2010 was abolished and permanent Deliberation committee was introduced. So far, ordering organization selected the best method suitable for the design and comprehensive evaluation method in the turnkey bid construction. Comprehensive evaluation method have bid price design score coordination, weighted basis, the best design approach fixed amount, five successful bidder decision method in addition. Design deliberation branch committee in the successful bidder decision way configured and operated branch members of special design consultation committee, But main agent changed from committee deliberation pull system to permanent committee deliberation, as well as and The lobby burden was not improved. This similar to the past at the portion of the design deliberation and the way of the design deliberation in the turnkey bid construction. Therefore it is necessary to improve the design deliberation system. In other words, design score and technology competition should be adapted to determine a successful bid. This study suggested the operating system of the design deliberation, the decision method problems of the successful bidder and ways to improve the design deliberation.

Although the construction industry has been rapidly increased at its size and technologies as a locomotive of the economy development in Korea, most construction companies have not paid their attention on the construction risks seriously. However, they have been experienced a lot of business deterioration and project instability during the IMF crisis and WTO entry, and trying to figure out a way to manage the construction intrinsic risks systematically. Some top ranked construction companies have already developed and been implementing a risk management system for the oversea construction projects applying for the marketing and bidding stage, but not for the domestic construction projects during construction phase yet. This paper proposes a construction risk management system model for the site personnel to understand and manipulate very easily in the construction project.

Since the competitive market environment was introduced into the electric power industry, the structure of the industry has been changing from vertically integrated system to functionally unbundled and decentralized system composed of multiple (decision-making) market participants. So the market participants such as Gencos or LSE (load serving entity) need to forecast the market clearing price and thus build their offer or bidding strategies. Not just these market players but also a market operator is required to perform market analysis and ensure simulation capability to manage and monitor the competitive electricity market. For fulfilling the demand for market simulation, many global venders like GE, Henwood, Drayton Analytics, CRA, etc. have developed and provided electricity market simulators. Most of these simulators are based on the optimization formulation which has been used mainly for the least cost resource planning in the centralized power system planning and operation. From this standpoint, it seems somehow inevitable to face many challenges on modeling competitive market based on the method of traditional market simulators. In this paper, we propose a kind of new method, which is MAS based market simulation. The agent based model has already been introduced in EMCAS, one of commercial market simulators, but there may be various ways of modeling agent. This paper, in particular, seeks to introduce an model for MAS based market simulator.

The BTL project, 4 years since its operation. has benchmarked the PFI Project in Japan and has been introduced. Given the evaluation step to select a preferred bidder, in a technological factor, the basic plans are corrected and complemented, whereas in a price factor, the low price bidding system is being enforced. There is concern that how to select preferred bidders and how to operate project costs during operation and management period may be problematic. Thus, in this study, using the Analytic Hierarchy Process, the method of deciding the priority to select preferred bidders in an early stage of the project and the evaluation model to evaluate the validity of BTL project expenses in process of project enforcement are established. Targeting the group composed of experts who have experiences in the BTL project. Then, the levelling of evaluation factors and grouping have been carried out as following : LCC analysis and disbursement for government including two more detailed factors.

The relationship between suppliers and customers is treated importantly not only in the traditional business-to-business (BtoB) commerce but also in today's Internet environments. On the one hand, most of Internet-based BtoB commerce services like customer-centric e-procurement, supplier-centric e-sales or intermediary-centric e-marketplace focus mainly on the selection of partners according to bidding, auction, etc. This point may result in the problem of overlooking the relationships between suppliers and customers. To overcome this problem in this paper, an intelligent agents-based supply chain operation architecture is proposed and appraised considering the relationship and its adaptation.

Construction Management tends to create a formal procurement resulted from recent legislative procedures system in domestic construction industry. However, the fact that construction Manager(CMr) has been chosen, in practice, under a poor circumstance in selecting and discriminating specialty requires the more optimal procedures. Therefore, in this research, we analyze the existing shortcomings. the various procedures, influence factors, and the criteria to be considered in selecting and evaluating CMr. Also. this study suggests the improved method based on the facts above. To accomplish the construction project successfully, it is one of the advanced schemes to choose an adequate CMr needed to the project through the precision in the formation and application of the procedure as well as the suggested criterion in selecting CM.
