Abstract: | Concurrent product and process design (CPPD) can be handled by developing a computerized team approach. In the team approach, CPPD at the top-level abstraction is treated as a two-objective optimization problem with a view to two teams: design and manufacture. The design team aims to optimize the overall product functionality (or performance) and the manufacture team to minimize the total manufacturing cost. Satisfaction metrics are used to characterize the degree of how each team prefers a design in seeking the most favorite that best fulfills the goal of a team. Using min and geometric mean operators as a baseline, the satisfaction levels of two teams can be aggregated with respect to strategic team paradigms derived from game theory. With satisfaction metrics, three dual-team based CPPD models are developed, along with the computational algorithms, in an attempt to reveal team activities in the context of design. The procedures to simulate and implement various team design models are demonstrated through a design example. |
