Abstract: Aiming at the module organization structure optimization of modular product manufacturing enterprise,a module evolution method was proposed to improve the production stability.Product module network model was established by using complex network theory to analyze the topological feature of network deeply.On the basis of analyzing vulnerability and robustness of the network,the product module network's brittleness risk estimate function was established by considering factors such as arrival rate,completion rate,and use rate to evaluate the uncertainty of network stability.According to brittleness risk source,module evolution strategy was proposed to improve network's stability.To guide the network change caused by module evolution and to achieve the purpose of dynamic control of product module network's vulnerability,the dynamic evolution model was built.A series of special vehicles was introduced to verify the presented method,and the results confirmed the effectiveness and rationality of the method.

Key words: module evolution, product module network, brittleness, stability

摘要： 针对模块化产品的模块组织结构优化问题,提出一种基于模块演化以提高模块组织结构稳定性的方法。使用复杂网络理论构建了产品模块网络,并深入分析了网络的拓扑特性。在分析产品模块网络的脆弱性和鲁棒性的基础上,综合考虑到货率、完成率和使用率等因素,建立了产品模块网络的脆性风险熵函数,作为产品模块网络稳定性的不确定性表征。考虑脆性风险来源,提出模块演化方法以提高产品模块网络稳定性。建立了产品模块网络的动态演化模型,指导模块演化带来的产品模块网络变化,从而达到动态确定产品模块网络脆性风险的目的。以某系列特种车辆的模块组织结构为例进行实验,证明了所提方法的有效性和合理性。
