摘要: 提出一种基于有向加权网络模型的复杂产品多源设计变更路径优化方法。首先,以零部件为节点,零部件之间的物理连接关系为边构建复杂产品结构的有向网络模型。采用Linkrank算法计算零部件连接重要度,考虑节点出度和入度定义变更传播指数,进而结合设计任务执行时间及变更传播概率计算变更传播强度(Change propagation intensity,CPI),并以此作为边的权重,建立变更分析网络模型。其次,选取多个零件作为多个变更源,通过改进的蚁群算法对复杂产品多源设计变更搜索累积变更传播强度最小的最优传播路径。最后,以某型号直流电钻行星轮齿轮箱多源设计变更为例验证了方法的可行性和有效性。

Abstract: A multi-source design change propagation routing approach for complex product is proposed based on the weighted and directed network model. First, the directed network model for the structure of complex product is constructed through mapping the parts and the relations among them into the vertices and edges, respectively. The importance degree of connections among parts is calculated by using Linkrank algorithm. The change propagation index is defined considering the out-degree and in-degree of vertices. Then the change propagation intensity is calculated incorporating the lead-time of design task, the change propagation likelihood and the pre-defined two parameters. Take change propagation intensity as the weight of the edges, the change analysis network model is constructed. Second, more than one parts are selected as the multi-source of design change, then the optimal propagation path with the minimal accumulated change propagation intensity is searched by employing a modified ant colony optimization algorithm. Finally, the multi-source design change propagation path searching of DC Drill Planetary Gearbox is established to elaborate the feasibility and effectiveness of the proposed approach.

Key words: change propagation intensity, complex product, multi-source design change, path optimization
