Abstract
Design goals are the required functions of the design elements needed to realize the design specifications of a product. In this study, it is assumed that the design goals can be explicitly expressed by the design parameters, and accordingly the mechanical design process is the assignment of proper design goals and their realization through the evolutionary refinement of the design parameters. Thus an integrated design system is proposed to assign the design goals and refine the values of the design parameters. In the design system, a genetic engine that utilizes a genetic algorithm is installed, which leads to an evolutionary design.
