Abstract: The coupling change of parameters is inevitable in product change design. In order to complete decoupling and improve the efficiency of design change, an optimization method of parameter coupling change propagation path based on elite backtracking - simulated annealing hybrid algorithm is proposed. To begin with, a complex network model of product parameters with parts as communities is constructed with product parameters and design formulas between parameters as nodes. Then, the basic model of change propagation is established through the analysis of parameter associations in the model. The eigenvector centrality algorithm is improved to calculate the propagation index of parameter changes, combining the associated propagation strength and cost coefficients to quantify the propagation cost of parameter changes. On this basis, a decoupling model of product parameter coupling change is developed, taking into account the variability of the coupling situation in the process of parameter changes. Then, the problem of parameter coupling changes is solved by the attenuating effect of potentially decoupled parameter nodes on the coupling. Besides, the elite backtracking algorithm is mixed with the simulated annealing algorithm. Other potential propagation parameters are accepted with some probability as alternative parameter nodes, and the propagation path with the lowest change propagation cost is optimized by changing backtracking and path reconstruction. Finally, the effectiveness of the method is verified with an example of coupling change of a model of overhead crane trolley parameters.
