Railway Fixed Facilities Coordination Evaluation Research Based On Amendatory Entropy Weights-Grey Correlation Model

Railway fixed facilities play an important part of railway. In order to improve transport capability and quality, coordination and elements of all kinds of railway fixed facilities were analysed. Then, the paper put forward railway fixed facilities coordination evaluation index and evaluation model. So as to further optimize transport capability resources of railway.Firstly, the paper introduced content of railway fixed facilities. As the same time, present situation and coordination of rail marshalling yard, rail freight yard and railway line were analysed as important. And railway fixed facilities coordination evaluation index was set up. Secondly, the paper put forward the amendatory entropy weight-grey correlation degree evaluate model. At last, freight station coordination of18railway bureau, rail marshalling yard coordination, and dotted line coordination were calculated.This essay mainly focused on railway fixed facilities coordination evaluation index and evaluation model. In the part of railway fixed facirities coordination evaluation index.The paper set up railway fixed facirities coordination evaluation index based on capability coordination analysis and technology standard coordination analysis of rail marshalling yard, rail freight yard and railway line. In the part of railway fixed facirities coordination evaluation index model. At first, grey correlation degree model was established by all kinds of evaluate models were analysed. Second, entropy weight evaluate method was established as main method to establish index weight. And the Delphi method was applied to revise it. At last, improved entropy weight-grey correlation degree evaluate model was established. With help of Matlab calculation, the result of evaluate model is consistent with objective law. And it basically proved the utility and practicality of the model.
