A STUDY ON THE OPTIMIZATION OF SHIP DESIGN PROCESS'USING WILDCARD GA

摘要

The performance of the product and the design time are influenced by the design process. Therefore, it is very important to advance the design in an appropriate design process. However, the design process is generally relies on the experiences of the designer and it is difficult to examine their characteristics. In this study, design process of ship principal particular is optimized by using the optimization technique. Moreover, the features of the optimized design processes are examined. Characteristics of this paper are following points; 1. The best design process is generated by using the Wildcard Genetic Algorithm which can deal with the uncertainty of product information, i.e. what design variable should be fixed and what should not be fixed. 2. By executing the optimization, two kinds of design processes are generated i.e. performance valuing process and feasibility valuing process. 3. Characteristics of the optimized design processes are analyzed by using our design support system in which dependency of the information and changes in the range of constraints and objective functions according to the progress of the design are visualized. In this paper, optimization method of design process and the results of the optimization are shown. Moreover, overview of our design support system and features of the optimized design process are shown. As a result, effectiveness of our optimization method and design support system is shown.
