摘要: 产品变更设计过程中参数的耦合变更不可避免,为顺利完成解耦,提高变更设计效率,提出一种基于精英回溯-模拟退火混合算法的参数耦合变更路径优选方法。首先,以产品参数及参数间的设计公式为节点,构建以零件为社区的产品参数复杂网络模型,通过对模型中参数关联的分析,建立变更传播基本模型;对特征向量中心性算法进行改进,以计算参数变更传播指数,进而结合关联传播强度及成本系数量化参数变更传播代价。在此基础上,考虑参数变更过程中耦合情况的差异性,建立产品参数耦合变更的解耦模型,通过潜在解耦参数节点对耦合的衰减作用,解决参数耦合变更问题。然后,将精英回溯算法同模拟退火算法进行混合,以一定的概率接受其他潜在传播参数作为备选参数,通过变更回溯及路径重构优选变更传播代价最小的传播路径。最后,以某型号桥式起重机小车参数耦合变更为例验证了该方法的有效性。

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.

Key words: parameter coupling change path optimization, change decoupling model, cost of change propagation, elite backtracking- simulated annealing hybrid algorithm
