摘　　要：为提升铁路技术站管理水平,本文对于技术作业环节进行量化排序,将技术站作业流程分类为25个环节。以灰色关联和解释结构模型对作业环节的效率、作业安全和人身安全进行关联度分析,加入作业安全和人身安全虚拟网络节点,创建效率-作业-人身复合网络。利用信息熵模型,计算网络中弧的权重,提出改进含权K-壳模型。最后利用SIR(susceptible-infective-removal)模型对各方法排序进行验证。结果表明:改进含权K-壳模型与度中心性等7种排序方法对比,在小型网络中具有较好的扩散性能。通过独立2000次模拟SIR扩散过程,原始点位数量与模型性能呈正比,改进含权K-壳模型与度中心性、特征向量中心性、含权K-壳在节点影响度值方面具有较强的正相关性。In order to improve the management of the railroad technical stations,the technical operation links are quantified and ranked,and the technical station operation process is classified into 25 links.The gray correlation and interpretive structure model is applied to analyze the correlation degree of the operation links'efficiency,operational safety and personal safety,and the virtual network nodes of operational and personal safety are added to create the efficiency-operational-personal composite network.The information entropy model is utilized to calculate the weights of arcs in the network,and an improved weighted K-shell model is proposed.Finally,the SIR(susceptible-infective-removal)model is utilized to validate each method ranking.The results show that the improved weighted K-shell model has better diffusion performance in small networks in comparison with seven ranking methods such as degree centrality.By independently simulating the SIR diffusion process 2000 times,the original number of points is positively correlated with the model performance.The improved weighted K-shell model has a strong positive correlation with degree centrality,eigenvector centrality,and weighted k-shell in terms of nodal influence degree values.
