Evaluation of the node importance for large heat exchanger network based on complex network theory
摘要
Abstract
Because of the complexity of large-scale heat exchanger network,it is important to investigate the importance of heat exchanger nodes in heat exchanger network. It can provide guidance for the control and safe operation of heat exchanger networks,as well as engineering practices. In this paper,the network topology structure of large-scale heat exchanger network was constructed by treating heat exchangers as nodes and treating the transfer of interference between heat exchangers as edges. Based on the complex network theory,the strategies and models for evaluating the node importance of the heat exchanger network were proposed. Firstly,the importance of nodes were evaluated by the multi-attribute decision method based on the degree centrality, betweenness,closeness and eigenvector centralities. Next, considering the direction of case heat exchanger network,PageRank algorithm was used to evaluate the importance of nodes. Considering the results from these two algorithms,the final results were obtained. The case analysis showed that the strategy is effective and it can evaluate the node importance from different views,which will enrich the node importance evaluation theory for heat exchanger network.关键词
