Abstract: Aiming at the internal structure's strong coupling and configuration solution's low efficiency and accuracy of complex products, the optimization technology for complex product configuration model based on Coupling Intensity Design Structure Matrix(CIDSM)was proposed. The Product Configuration Structural Body(PCSB)was defined, and the coupling analysis for configuration model and quantitative study for PCSB coupling relationship were achieved according to the parent child and constraint relationship between PCSB. Coupling intensity design structure matrix of configuration model was obtained by mapping, and the ploymeric set of PCSB was formed by decomposing CIDSM and determining the polymeric degree index function. To tear the ploymeric set based on pure supply degree decoupling algorithm, PCSB sequences was reorganized and configuration model was optimized. This technology was applied to practical use in the configuration design of CNC machine tools, and the efficiency and accuracy of configuration were improved remarkably.
