The Evaluation of Intercity Railway Train Operation Plan Based on Multi Index Cosine Decision

Abstract

The evaluation of train operation plan is the important means of optimizing train operation plan. It is also a complex multi index comprehensive evaluation problem. Based on comparison of angle cosine value between line segment in each scheme and ideal line segment in ideal scheme, cosine decisions get the optimal decision scheme. Through the main factor analysis of intercity railway train plan and by combining the entropy weight coefficient method and using the cosine decision method the evaluation of index system of intercity railway train plan is established. Taking the Shanghai-Nanjing intercity railway for example, the results shows that cosine decision is adapt to the actual operation with simple calculation process, easy to use. The evaluation model should provide new ideas and methods for the optimization the train operation plan so as to provide technical support for intercity railway operation.
