This research discusses and develops the optimization methodologies for product variety design, which means the challenge to simultaneously design multiple products. Following the succeeding reports, this paper proposes a simultaneous optimization method for both module combination and module attributes of multiple products, which is viewed as the third class of product variety optimization in the first report. While it is the most difficult one among the classes, it includes a hierarchical structure on the design optimality, which is composed of commonality and similarity pattern, similarity directions, module attributes, under a systematic understanding of product variety representation. Based on such structure, this paper configures an optimization method for both module combination and module attributes across multiple products. The optimization method hybridizes a genetic algorithm, a mixed-integer programming method with a branch-and-bound technique, and a constrained nonlinear programming method, i.e., a successive quadratic programming method. In its optimization process, the first optimizes the combinatorial pattern, the second optimizes the well-structured directions, and the third optimizes the continuous module attributes under the others. Finally it is applied to the simultaneous design problem of multiple airplanes to demonstrate its validity and effectiveness.
