Abstract (English): To compensate for the limitations of previous studies, a complex network-based method is developed for determining importance measures, which combines the functional roles of the components of a mechatronic system and their topological positions. First, the dependencies among the components are well-represented and well-calculated. Second, a mechatronic system is modeled as a weighted and directional functional dependency network ( FDN), in which the node weights are determined by the functional roles of components in the system and their topological positions in the complex network whereas the edge weights are represented by dependency strengths. Third, given that the PageRank algorithm cannot calculate the dependency strengths among components, an improved PageRank importance measure ( IPIM) algorithm is proposed, which combines the node weights and edge weights of complex networks. IPIM also considers the importance of neighboring components. Finally, a case study is conducted to investigate the accuracy of the proposed method. Results show that the method can effectively determine the importance measures of components. [ABSTRACT FROM AUTHOR]
Abstract (Chinese): 针对当前已有重要性度量研究的局限性,提出一种基于复杂网络和依赖关系的机电系统中零部件重 要性度量方法,该方法结合了机电系统零部件在系统中的功能角色及其在复杂网络中的拓扑位置.首先,探 索了机电系统中零部件之间的依赖关系的表示和计算方法.其次,将机电系统中的零部件建模为有向加权 依赖复杂网络(FDN),其中,点权由零部件在系统中的功能角色及其在复杂网络中的拓扑位置共同确定,而 边权由零部件之间的依赖强度表示.考虑到 PageRank算法无法计算零部件之间的依赖强度,在 PageRank 算法的基础上提出一种 IPIM 算法,该方法结合复杂网络的点权和边权,并考虑了机电系统中邻居零部件的 重要性.最后,通过实例验证了所提方法的准确性,该方法能够有效地确定机电系统中零部件的重要性.
