Abstract: Aiming to the coupling analysis for heterogeneous module combination design, a comprehensive dependency matrix (CDM) that can not only present the direct dependency but also the indirect dependency simultaneously is proposed. A coupling analysis method based on evolutionary strategy is presented, for which the fitness function and algorithm operator used in coupling analysis are also given. The coupling analysis based on CDM will contribute to getting the inside of the dependency between the design functions and variables. The change propagation analysis of the combination design that is integrated in the construction progress of CDM is also performed. The analysis result can descript the coupling relationship between the heterogeneous module more comprehensively and clearly, and provide a effective and efficient method for the coupling analysis of heterogeneous module.
