This paper deals with the Design Process Simulator which can examine the influences of the differences of design processes on the performance of the designed product, quantitatively. In order to realize this, ship design is divided into two problems, i.e.design process planning and product design, and a new design support system has been developed in which product information is automatically generated by using the optimization method based on the design process information given by the designer. The characteristics of the proposed system are following points: 1) The design process is described in the system by combining the components which are the base units of the information processing to generate output data based on the input. 2) Optimization problem is automatically defined based on the design process expressed with the chain of components, and optimum product information is generated by executing the optimization. 3) During the optimization described in above 2), not only the optimum solution but the solutions in the middle of the optimization processes are also managed in the system. Robustness of the design process is evaluated by the use of these data in addition to the performance of the product. 4) In order to realize above 2) and 3), design process manager is defined. 5) Re-design and feedbacks of the design are also achieved in the system by describing the conditions of feedbacks into the design process manager.Based on the above discussions, the prototype system of the Design Process Simulator has been developed. Moreover,examples of the design process simulations intended to the ship initial design stage are shown in the paper. Thereby, the validities of the proposed method are shown.
