An issue of globalized and competitive business environment is a transformation of manufacturing strategy for rapidly product development. To copy with these trends, building up a market from various product is becoming conspicuous the core strategy of manufacture. Therefore, it is increasing of necessity for the environment of collaborative product development. As a part of corresponding for these demands, we propose the method that allows easy and rapid integration of legacy resources within the company and between departments. The proposed framework can easily construct a distributed environment for collaborative design between departments in the companies. It was implemented using CO/sup TM/ based on DOME (Distributed Object-based Modeling Environment) that is knowledge based engineering solution.

Due to the widespread availability of the internet, large-scale and dynamic distributed projects in industry are becoming popular. We present a distributed, collaborative, and adaptive control approach for decentralized multiple projects, which is one of representative project environments in modern e-enterprises. In this paper we deal with short term scheduling and rescheduling of resources, which are shared by multiple projects. We in specific, address the dynamic nature of the situation. We model this as a dynamic economy, where the multiple local markets are established and cleared over time trading resource time slots(goods). Local markets are modeled using a combinatorial auction mechanism. Due to the dynamic and distributed nature of economy, through our approach we can achieve higher levels of flexibility, scalability and adaptability.

본 연구에서는 비교적 적은 양의 시장자료를 이용하여 장기적 안정성을 갖춘 예측치를 도출할 수 있는 것으로 알려진 확산 모형을 중심으로 기존의 신상품 시장예측 방법론에 대하여 고찰하고, 과거 시장자료가 거의 존재하지 않는 정보통신 관련 품목에 대한 국내시장 예측 모형 개발 방법론을 제안하였다. 본 연구에서 제시된 방법론에 의거하여 개발될 예측 모형은 기존의 정보통신분야 전략품목 이외의 여타 관련 품목, 나아가 향후 등장하게 될 새로운 품목에 대한 예측 작업에도 적용이 가능하며, 해외 기관이 제공하는 국내시장 자료에 대한 검증 툴로서의 역할 역시 제공할 것으로 기대된다.

The objectives of the study are to build a structural model of intra-organizational diffusion of information technology and to test this model. Data were collected from senior managers of the purchasing department through questionnaires and statistically analyzed using the structural equation modeling. The questionnaires were concerning firm's database system adoption. Key findings of the study are as follows. First, buying center dynamics (i.e., buying center decision centrality, participation in buying center, and top-management support) are substantially related to the intra-organizational diffusion. Second, environmental characteristics (i.e., market turbulence, technological turbulence, and competitive intensity) indirectly affect on intra-organizational diffusion via buying center dynamics.

This paper presents a new approach to HVDC system control for damping subsynchronous oscillation (SSO) involving HVDC converters and turbine generator shaft systems. This requires a novel eigenvalue analysis (NEA) program, derivation of HVDC system modeling considering steady-state conditions and dynamic conditions in the combined AC/DC system, and an appropriate control scheme. The method suggested makes possible the design of a subsynchronous oscillation damping controller (SODC) to provide positive damping torque for the range of torsional modes in combined AC/DC systems. There are three steps involved in the design of a SODC； first the worst torsional mode is determined using the NEA program, next the SODC parameters are designed for the range of that torsional mode, and then finally an off-line simultaneous time domain program such as PSCAD/EMTDC is used to verify the parameters of the SODC. The suggested SODC design method is applied to two AC/DC systems, and its practicality is verified using the PSCAD/EMTDC simulation program.

In this paper, we explore the ubiquitous system that provides new business opportunities in the context of digital convergence. Exploiting the value network of the proposed ubiquitous system, we analyze strategic market drivers that define the speed and direction of the evolution path for ubiquitous industries. Motivated by the dynamic growth of ubiquitous industry, we design a set of ubiquitous business models that pave the way for firms to identify profitable business cases. In addition, we analyze the evolution path of the proposed business model such that the model can be implemented in the life-cycle of ubiquitous industry. Futhermore, we develop a modeling framework for selecting a suitable business model and for evaluating the performance of the selected business model.

본 논문은 B2B(Business To Business)전자상거래상의 거래기업에 대한 신뢰도 및 경제동향에 따른 거래기업의 변동율을 예측 분석하는 모형을 제시한다. 거래기업의 자금흐름은 거래기업의 은행으로부터 움직이게 되고, 따라서 거래하고자 하는 신뢰도는 그 거래대상 기업의 성장성이나 자금흐름 등과 같은 기본적인 재무비율 보다는, 거래기업은행에서 바라 보는 거래기업의 신뢰성이라는 측면에 비중이 더 실린다. 본 논문에서는 이러한 모형에 대한 알고리즘 설계 및 인터페이스 관한 설계를 하고, UML(Unified Modeling Language)을 이용하여 Component 로 구현을 한다.

As the overseas direct purchase market grows rapidly, firms are setting up various strategic directions to attract consumers. However, many previous researches on this issue have focused on consumption behavior based on consumers' motivation and demographic factors, so there is a certain limit to suggest practical implications for firms. Therefore, this study proposed modeling to understand how firm's strategic direction influences consumers' acceptance behavior in order to overcome these limitations. For this purpose, this study conducted a survey on 357 domestic consumers and conducted empirical analysis through structural equation model analysis. As a result, the effort expectancy of overseas direct purchase site has a strong influence on consumer intention as much as performance expectancy. We also found that product variety had the strongest impact on performance expectancy and that web site reputation directly affected consumers' behavioral intention as well as purchasing behavior.

Purpose: The purpose of this study was to investigate sales managers' strategic focus on customer acquisition, specifically its effect on salespeople's performance. In addition, this study aimed to determine how salespeople's interpersonal skills, salesmanship skills, and technical knowledge affect the relationship between customer-acquisition management and salespeople's performance. Research design, data, and methodology: This study conducted a survey of 310 salespeople working at pharmaceutical companies. A structural equation modeling approach was applied to test the main effects and interaction effects using AMOS. Results: The results indicated that both managers' customer-acquisition orientation and salespeople's salesmanship skills and technical knowledge positively affected the latter's performance. Further, it was found that the higher the technical knowledge of the salesperson, the greater the effect of the customer-acquisition orientation on sales performance. Conclusions: Sales managers should enable salespeople to quickly acquire technical knowledge with respect to the market, products, competitors, and company policy so that they can bring greater synergy to the customer-acquisition orientation.
