Abstract
Reconfigurable assembly fixtures are major components of a reconfigurable assembly system. They are precision components which require an intensive design process due to their usage and interaction with other components in the assembly system. Concept selection is a time consuming activity in the engineering design process, because it involves decision making and consideration of multiple factors. A computer aided design approach of four concepts was developed for a reconfigurable assembly fixture, based on functional requirements, cost, and manufacturability. The weighted decision matrix and analytical hierarchy process was used to compare these concepts. The decision criteria and evaluation technique used during this concept selection process is novel thus calling for its application in design of engineering components. The results of the two methods are presented graphically and the variations in the results obtained are used to judge the suitable method among both processes for the optimal design.
