Evaluation Methods in Various Fields

The identification of key nodes is conducive to improving the accuracy of network performance analysis. The topology of the Chengdu Metro Network (CMN) is analyzed based on complex network theory, a node importance evaluation index system including regional prosperity and node accessibility is constructed. Multi-comprehensive evaluation methods such as Relational Analysis, TOPSIS, Principal Components Analysis, Entropy Weight Method, etc., were used to rank 136 nodes. It is identified that 30 key nodes headed by East Chengdu Railway Station (56). At the same time, some starting, ending and intermediate stations with low degree or betweenness are equally important in urban rail transit network. Key precautions and maintenance are needed to ensure the normal operation of the CMN.
