1110 A Study of Knowledge Representation Model for Welding Activity Evaluation

Abstract

To improve the quality of product design, it is important to evaluate productivity at an early phase. We have studied productivity evaluation methods using Design Parameter Check (DPC) functions and their rule representation model in product design process. Therefore, high visibility and generality are indispensable to the rule representation model. Our proposed model called "iSmartModel" describes the rules as simple scripts using part structure and relationship between parameters of part attributes. This paper focused on welding activity as a productivity evaluation. We enhanced our model to represent welding structures, and implemented a prototype system coupled CAD systems for welding activity evaluation. It enables user to evaluate work clearance and work posture in piping design.
