Logistics is by no means a new subject area. The concept of logistics goes way become more complex as technology advances, and logistics requirements have increased accordingly. In 1964, when ILS philosophy formally came into being, ILS was defined in general terms and did not describe what actions an ILS program should accomplish. ILS philosophy have been developed from 1964 through 1980. In 1982, United States Department of Defense formulated a new concept, CALS. CALS is the strategy that the US defense development to management the transition to integration and automated interchange in defense system engineering, manufacturing, and logistic support. Its goal is to use the inherent features of digitized data to revolutionize the function of data -gathering, data storage and data - transfer techologies associared with the development of defense systems. The Result will be systems that are cheaper, more reliable, and easier to maintain. To define CALS's character, the purpose of this papers compare two concepts - CALS and ILS. The elements of CALS consist of standads and EDI. The elements of ILS include LCC(Life Cycle Cost), LSA(Logistics Support Analysis), LSAR(Logistics Support Analysis Rcord), Aquisition Cycle.

본 논문에서는 싸이클론 청소기들의 성능 및 환경성 평가를 실시하고, 결과를 분석하여 환경에 대한 영향을 최소화하기 위한 개선방안에 대하여 연구하였다. 환경성 평가에는 제품의 원재료 취득, 제조, 운송, 사용 및 폐기 과정에 대해서 제품이 환경에 미치는 영향을 정량적으로 평가하는 전과정 평가(life cycle assessment, LCA)를 간략한 형태로 이용하였다. 2가지의 싸이클론 청소기의 성능을 각 제품의 전력량, 흡입력, 소음, 온도를 관련 규정에 따라 측정하여 비교하였으며, 환경성 평가를 통해 전과정 중 사용단계의 에너지 소모가 가장 많다는 결과를 얻었다. 이를 바탕으로 사용단계의 에너지 소모를 줄이기 위해 싸이클론 청소기 내부에 배플(baffle)을 설치하고, 유지/소모품인 필터의 교환 주기를 늘려 사용단계의 에너지를 감소시키는 개선 방안을 제안하였다. 또한, 싸이클론 청소기의 불필요한 원료 물질 및 부품을 제거하고 상대적으로 재활용률이 높은 원재료 물질로 대체하는 방안을 고려하여 청소기의 중량은 줄이고, 재활용률은 높여 전과정에 대한 에너지 소비를 낮춘 친환경 청소기에 관하여 연구하였다.

기존의 대기전력차단시스템의 단점을 극복하고자 최근 지능형 대기전력 제어시스템이 개발되기에 이르렀다. 하지만 기존의 시스템 보다 투자금액이 높은 문제로 도입에 대한 타당성 검토가 필요하다. 이에 본 연구에서는 LCCA 및 LCA를 이용하여 경제적 측면 및 환경적 측면을 종합적으로 분석하여 도입의 타당성을 검토하였다. 또한 결과의 신뢰성을 확보하기 위하여 민감도 분석을 실시하였다.

Today the tastes of consumers change rapidly and the kinds of the products become diverse. There- fore the product life cycle becomes shorter and shorter. Moreover the save of resources and the recycling for the environmental preservation are the essential theme. On this the necessary information for the product development increases enormously. For the right use of the information the design process should be supported by the proper design tool. For this the 'design catalogue system for recycling' is suggested here. This system consists of four parts. that is, 'the existing automobile system database', 'welting principle database', 'Assessment system of the ease of disassembly' and 'one's own product development ratabase'. By the use of this system the product development period could be reduced about 30% drastically.

The terminology such as ecology, environment problems, ecosystems, ecofactory, and others related to environmental problems have been recently used in manufacturing systems, since the modern industries have to consider a global ecological crisis. The indifference of recent environmental problems which may be faced now has been paid attention to all engineering areas. In this paper, manufacturing functional requirements such as disassembly, disposal, disposal, or recycling are considered in the integrated product design development, which have not been considered well in the preliminary design stage. Those functions will contribute to reduce the waste and to long the product life cycle, which also satisfies the business benefits and customer requirements. The concurrent design concepts should be applied to integrate all possible factors. Therefore, few practical concurrent engineering tools are presented in here. The objective of this paper is to develop a called green manufacturing systems for integrated product design development by concurrent design concept which can give the desirable result in product design.

With the recent trends of electronic commerce moving from B2C to B2B, Collaborative Product Commerce (CPC) is widely adopted as a part of B2B in the virtual collaborative environment. This paper proposes an integrated CPC framework supporting collaborative works between businesses by sharing product data and collaborative process between global enterprises and their customers, who are related to product life cycle, and integrating application systems in order to realize a true B2B electronic commerce. To integrate into a loosely coupled structure, various web service technologies such as XML, SOAP, WSDL and UDDI are utilized as its fundamentals and on that basis, a CPC integration framework is implemented through the Internet to support real-time operation providing interoperability among all the different applications operated on various platforms which have been developed using different languages and adopted by different companies.

This paper introduces an approach to ontology-based framework for knowledge management in a product development domain. The participants in a product life cycle want to share the product knowledge without any heterogeneity. However, previous knowledge management systems do not have any conceptual specifications of their knowledge. We suggest the three levels of knowledge framework. First level is an axiom, which specifies the semantics of concepts and relations. Second level is a product development knowledge map. It defines the common domain knowledge which domain experts agree with. Third level is a specialized knowledge for domain, which includes three knowledge types; expert knowledge, engineering function and data-analysis-based knowledge. We propose an ontology-based knowledge framework based on the three levels of knowledge. The framework has a uniform representation; first order logic to increase integrity of the framework. We implement the framework using prolog and test example queries to show the effectiveness of the framework.

To achieve rapid developments and cost savings in manufacturing industries including automotive die shops, new paradigm and its supporting systems of information managements through total product life cycle are needed for concurrent and collaborative engineering. For manufacturing of automotive press dies, integrated and efficient managements of PPR information including product, manufacturing process and resource are essential. In this paper, we introduce a PLM approach to achieve engineering collaborations in product development and production of automotive dies. To prove concepts and benefits of PPR information managements, we implement new business workflow and detail procedures, PPR information management system and other related applications. By PPR information managements in PLM, improvements in quality of engineering results and savings in time from design to production of dies are possible.

This system consists of four parts, that is, 'the existing automobile system database', 'working principle database', 'assessment system of the ease of disassembly' and 'one's own product development database'. By the use of this system the product development period could be reduced about $30\%$ drastically.
