Purpose - Product purpose for optimal values solution for synthesize evaluative criteria and optimize product design values. In addition, product designer has to consider the product design to conform to project, laws and regulations, authentication, from the product design stage. Research design, data, methodology - How to use an evaluative criteria model's imprecise market data by evaluative criteria research design; product mapping relationships between design parameters and customer requirements using product predicted value method. An evaluative criteria model and their associated criteria status, product evaluative criteria model of results. Results - Therefore, after the enterprise product design project analysis, effectiveness and the customer degree of satisfaction must be appraised to obtain the maximum value for the benefit on behalf of the implementation goals, the promotion product level and market competition strength. Conclusions - In multi criterion decision making (MCDM), using its searching software capacity to obtain the optimal solution.

Purpose - This study focuses on the use of evaluative criteria software for imprecise market information, and product mapping relationships between design parameters and customer requirements. Research design, data, and methodology - This study involved using the product predicted value method, synthesizing design alternatives through a morphological analysis and plan, realizing the synthesis in multi-criteria decision-making (MCDM), and using its searching software capacity to obtain optimal solutions. Results - The establishment of product designs conforms to the customer demand, and promotes the optimization of several designs. In this study, the construction level analytic method and the simple multi attribute comment, or the quantity analytic method are used. Conclusions - This study provides a solution for enterprise products' multi-goals decision-making, because the product design lacks determinism, complexity, risk, conflict, and so on. In addition, the changeable factor renders the entire decision-making process more difficult. It uses Fuzzy deduction and the correlation technology for appraising the feasible method and multi-goals decision-making, to solve situations of the products' multi-goals and limited resources, and assigns resources for the best product design.

온톨로지 모듈화에 대한 필요성이 증가하고 있으며 이에 따라 다양한 방법으로 온톨로지를 모듈화하려는 시도들이 이루어져 왔다. 그러나 모듈화 과정을 통하여 생성된 온톨로지 모듈의 품질과 모듈화 일치성을 평가할 수 있는 공통된 기준인 평가 메트릭에 대한 연구가 부족한 실정이다. 본 연구에서는 소프트웨어 메트릭 이론을 바탕으로 하여 온톨로지에 적합한 모듈 응집도와 결합도 메트릭을 제안한다. 새로이 제안하는 메트릭은 기존의 온톨로지 메트릭과 상이하게 온톨로지 모듈을 적용 대상으로 하며 모듈의 클래스가 다른 클래스와 형성하는 관계의 유형을 세분화시킴으로써 관계 유형에 따른 영향도를 각각 반영할 수 있도록 하였다. 또한 제안한 메트릭의 검증을 위하여 메트릭 검증 프레임워크를 이용하여 이론적으로 타당성을 검증하고 웹 상의 온톨로지를 모듈화하여 적용하는 실증적 실험을 하였다. 본 연구에서 제안하는 온톨로지 모듈 응집도와 결합도 메트릭은 온톨로지 엔지니어들이 온톨로지 모듈과 모듈화 기법을 선택하여 사용하는 기준으로 활용할 수 있을 것이다.

The purpose of this study is to develop means to apply GIS and remote sensing technology to the analysis of Korean urban open spaces. To achieve this objective, a framework of analysis of urban open spaces was developed, and then the framework was applied for the evaluation of the potential and suitability of open spaces of Ansan City, which is a new town developed to accomodate industries relocation from Seoul, Korea, mainly due to their pollution problems. The software used in this study are IDRISI, a grid-based GIS, and KMIPS, a remote sensing analysis system. Both packages are based on IBM PC/AT computers with Microsoft DOS. Landsat MSS and TM data were used for the land use classification, land use change detection, and analysis of transformed vegetation indices. The size of the geographic data base is 110 rows and 150 columns with the spatial resolution of 100m$\times$100m. The framework of analysis includes both quanititative and qualitative analysis of open spaces. The quantitative analysis includes size and distribution of open spaces, urban develpment of open spaces, and the degree of vegree of vegetation removal of the study area. The qualitative analysis includes evaluative criteria for primary productivity of land, park use potential, major visual resources, and urban environmental control. The findings of this study can be summarized as follows. First, the size of builtup areas increased 18.73km$^2$, while the size of forest land decreased 10.86km$^2$ during last ten years. Agricultural lands maintained its size, but shifted toward outside of the city into forest. Second, the potential of open spaces for park use is limited mainly due to their lack of accessibility and connectivity among open spaces, in spite of ample acreage and good site conditions. Third, major landscape elements and historic sites should be connected to the open space system of the city by new accesses and buffers.
