Now days, the marketing environment is rapidly changed. Therefore, a lot of companies try to reduce production cost. Especially, Design is a important activities in new product development. While the concepts of design for manufacturable and concurrent engineering have made significant advances in integrating the design function with other areas in the firm. There are still major gaps in timely and accurate costing information available to designers. Inappropriate design could result in high redesign cost and delay in product relation. The generation of design and improvement is a time-consuming and mentally exhaustion process. It involves combining design features to generate as many potential design as possible. As not all features combinations are feasible, decision-makers have to narrow down the potential solutions and subsequently select appropriate design for further development. This new study is composed of 3 steps aiming at the Low Cost Design of the product. The three steps are consisted that setting up the target Cost, estimating the current functional cost, the design of a unit's reviewing according to the priority of the difference between the target cost and the functional cost.

This study compares the reasons why targe and Small companies are adopting electronic commerce(e-commerce) based on an assumption of difference between two groups of companies. We collected data for contemporaneous analysis by classification with two groups of companies in Korea and developed an integrated model from the empirical studies and made Question papers for inspection of created hypothesis. Hypothesis is composed with nine factors ; Customers, Suppliers, Pertner Firms, Competitors, Relative Advantage, Cost Compatibility, CEO's Innovativeness and CEO's Involvement. The research shows Large company is influenced significantly by Customers, Relative Advantage, Cost, CEO's Innovativeness and Small company is by Competitors, CEO's Involvement.

The Systems Engineering, as a methodology for engineering and management of today's ever-growing complex system, is a comprehensive and iterative problem-solving process. The process centers on the analysis and management of the stakeholders'needs throughout the entire Life-cycle of a system and searches for an optimized system architecture. There are many essential needs and requirements to be met when a system development task is carried out. Systems Engineering Management PLan(SEMP), as a specification for system development process, must be established to satisfy constraints and requirements of stakeholders successfully and to prevent cost overrun and schedule delay. The paper suggests a systematic SEMP development process and demonstrates a data model and schema for computer-aided systems engineering software, RDD-100, for use in the development and management of SEMP These are being applied to the systems engineering technology development task for the next-generation high-speed railway systems in progress.

본 논문에서는 대규모 네트워크에서의 부하분산을 고려한 QoS 라우팅을 제안한다. 이를 위해 경로설정을 위한 비용 산정 방식을 선계산 방식의 경로계산에서 제안하고 선계산된 다중경로들 중에서 경로를 선택하는 방안을 제안한다. 제안한 비용산정 방식은 도메인으로 분할된 대규모 네트워크의 QoS 라우팅에서 선계산 방식으로 경로를 설정하고, 이들 경로들의 예약 가능성을 높이기 위해 자원 예약 측면에서 가장 좋은 K개의 경로들을 부하분산을 고려하여 계산한다. 또한 이러한 다중 경로들 중에서 비용산정에 근거한 경로선택확률 에 따라 경로를 선택한다. 그리고 제안한 QoS 라우팅 방식을 transit traffic과 intra traffic에 모두 적용하여 도메인간 라우팅과 도메인내 라우팅을 무리 없이 연계하면서 transit traffic을 우선으로 하는 방식 을 제안한다. 따라서 본 논문에서 제안한 부하분산 QoS 라우팅은 전체 네트워크 자원의 최적사용 뿐만 아니라 자원의 부하 분산을 가능하게 할 것으로 기대된다.
