摘要: 为使工程信息格式相互兼容,需考虑工程软件数据格式之间的转换。建立了一个工程软件数据格式转换加权网络,并采用复杂网络分析方法,从复杂网络的静态特征指标如平均最短路径长度、加权聚类系数、边权分布、节点强度分布、权差异性以及加权相关性等方面对其进行分析。实验证明格式转换加权网络拥有较小的最短路径长度和较大的聚类系数,边权分布及节点强度分布符合指数分布,加权相关性表现出正相关的特性,故该网络为同向匹配的小世界网络。

Abstract: In order to make the format of engineering information compatible,the conversion between data formats of engineering software is considered.A weighted network on data format conversion of engineering software is established.Through the methods of complex networks analysis,the networks’ static characteristic index such as the average path length,the weighted clustering coefficient,edge weight distribution,node strength distribution,weight difference and weighted correlation are analyzed.The experiment results indicate that the weighted network of data format conversion has small average path length and large clustering coefficient,and the edge weight distribution and node strength distribution are consistent with exponential distribution.Besides,the weighted correlation shows positive feature.Therefore,the network is a small world network with positive correlation.
