Concurrent multidisciplinary mechanical design based on design task analysis and knowledge sharing

摘要

We have developed a systematic design task planning method based on a design structure matrix(DSM) and a lumped model-based framework for knowledge sharing in a concurrent design environment as key techniques for developing higher quality products in a shorter design time. The DSM facilitates systematic analysis of dependencies among design tasks and optimization of the design process. The framework based on a lumped model description of mechanical systems enables concurrent and cooperative workamong multidisciplinary designers at an early stage of the design process.In this paper, we also discuss the relationships between these techniques and the product development flow from product definition to detailed design.
