A module design aims to develop product architecture that consists physically detachable units such as module. To develop the system of module design, this paper suggests the methodology of part grouping, evaluation of modularization of a product for improving modularization. To determine modules, module concept is proposed to satisfy the objectives of a modular design. Therefore, there are functional, structural, and process modularizations in a modular concept. Module grouping can be accomplished by using an optimization model that maximizes the sum of the weighting. The present study proposes the p-median model and the direct clustering technique. The optimal clustering solution can be obtained by comparing two clustering techniques. To find the best solution among part groups, evaluation of modularization is performed based on the concept of module design. For the evaluation of modularization, evaluation criteria of modularization are used in the matrix table.

The purpose of this study is to construct technology product concept a deployment model on seeds type R&D projects. For this purpose, we have peformed the following studies : First, technology opportunities and market opportunities through ${\ulcorner}$perception analysis${\lrcorner}$ are captured by perceptional structure of technology experts and customers on the existing technologies and products. Second, the optimal technology product concept deployed by ${\ulcorner}$SAT(System Alternatives Tree)${\lrcorner}$ has been constructed by the ${\ulcorner}$PWBS(Project work Breakdown structure)${\lrcorner}$.

Today's product development requires simultaneous satisfaction of low cost, high quality and fast time to market. It is, however, difficult for product designers and engineers to achieve this goal due to too many requirements. This study shows integrated Computer Aided Engineering (CAE) approach can help to achieve such goal. CAE can not only support designers when decision needs to be made during concept design period but also provide evaluation of the designed parts and guidance to the best design of products during detail design period. Furthermore, integration with virtual prototyping concept can reduce number of actual prototyping and consequently reduce product development cost and time considerably. In order to demonstrate its possibility, example of washing machine development using CAE and its results are presented in this study.

The Korean navy has made many efforts to apply the concepts of PLM (Product Lifecycle Management) and M&S to its naval design and production. However, most of the efforts that have being applied to some acquisition processes, focused only on the element technologies without information models and data frameworks. This study discusses an information model of naval ships for advanced naval acquisitions. We introduce a naval ship product model, and it refers to the DPD (Distributed Product Description) concept of SBA (Simulation-Based Acquisition). To realize the product model concept, we design a data architecture and develop a Product Model Management System (PMMS) based on a PDM System. It is validated through the case study of building the product model of the battle ship that the PMMS has the applicability to effectively manage the naval ship acquisition data on the basis of a 3D product model.

Navigation Software for the various weapon systems has common functionalities which give the possibility of common use among them. SPL(Software Product Line) framework of the navigation software for weapon system refers to developing a standardized navigation software platform from common functionalities of navigation software, managing the standardized navigation software platform, and developing weapon system navigation software such as navigation software for missile, UAV(Unmanned Air Vehicle), submarine, and etc. from the standardized navigation software platform. In this paper, we propose SPL based navigation software development process, Integrated Development Environment and operational concept of SPL framework. The operational concept will be defined by specifying the role of every stake holders and their activity scenario. The Operational concept would be referenced to implement SPL for other domain through using with detail implementation guide.

In the present society where aesthetic designs would have product value, designs must be the ones that add flexible sensation as well as the energy of counteraction which escapes from and destroys existing concept. The 'creative expression' to reach such design objectives is one of the most important abilities which designers must possess and is an overall concept in problem solving of designing which participates in formative approach or image development as well as product concepts such as function or performance . In this research, the definition of creativity, environmental change of designing, conditions designers must possess followed by these things and creative design expressions researched in the past, etc are examined and by presenting design method for creative designing concept targeting mobile phones, it will attempt to contribute in the importance of creativity and improve creative value of designers.
