【摘要】：为防范复杂产品设计变更过程中易产生的雪崩效应,将复杂网络理论应用于复杂产品结构建模中,以零部件为节点,以零部件之间的物理链接关系为边,定义了功能负载值为边的权重,建立了有向加权的复杂产品零部件网络模型。对网络模型的度、度分布等核心参数进行统计分析,确定了网络类型。从零部件自身属性、网络拓扑属性、变更影响属性等方面定义了零部件重要度评价指标体系,并采用熵权模糊评价法评价零部件重要度。选取重要零部件,采用BBV无标度网络演化模型对复杂产品设计变更传播影响进行定量化评估。以某型号履带起重机设计变更传播影响评估为例验证了该方法的可行性和有效性。
[Abstract]:In order to prevent the avalanche effect in the process of complex product design change, the complex network theory is applied to the modeling of complex product structure. This paper defines the weight of the function load value as the edge, establishes the network model of the complex product parts with directional weighting, makes statistical analysis of the core parameters such as the degree and degree distribution of the network model, and determines the network type. The evaluation index system of component importance is defined in the aspects of network topology attribute and change influence attribute, and the entropy weight fuzzy evaluation method is used to evaluate component importance. The BBV scale-free network evolution model is used to quantitatively evaluate the influence of complex product design change propagation. The feasibility and effectiveness of this method are verified by a design change propagation impact assessment of a certain type of crawler crane.
