Product design and evaluation require a broad and varied set of information and analysis tools, and effective design and evaluation of a product during its design phase is critical if production costs are to be minimized. A system is described that integrates product design specifications with material and process databases, and a simulation-based analysis module. The system allows product design specifications to be evaluated in terms of economic and technical criteria. The system will serve as a training tool in the computer-integrated manufacturing courses in our undergraduate curriculum. It allows students to investigate ways to design better products through integration of design and manufacturing, and to explore trade-offs between design and manufacturing
