To develop a successful product in modern industry, it is necessary to incorporate design performance requirements, manufacturing processes requirements and cost considerations in the early stages of the product design cycle. In this study, a game-theoretic framework for integrated product design is discussed. A minimax game formulation is developed and applied to the design of a simplified automobile door. Results are presented with the design engineer, manufacturing engineer and cost accountant each represented by a player. The minimax game yields a conservative solution and represents the worst-case scenario. This study explores how the game-theoretic approach can be effectively implemented to design a product while satisfying conflicting requirements.
