Fuzzy Comprehensive Evaluation Method for the Train Working Diagrams Based on Rough Set Theory

Firstly, the necessity of comprehensive evaluation for train working diagram of line is analyzed, a comprehensive evaluation index system of train working diagrams is established, the comprehensive fuzzy evaluation model for the quality evaluation of train working diagrams is founded by using the comprehensive two-level fuzzy evaluation method. Then, introduces the basis idea of the rough set, the decision table was established by the rough set theory and makes some redundancy Indicators Simplified and determine the relevant evaluating indexes by establishing decision-making table. Finally, Comprehensive evaluation for the index system of train working diagrams is made. The instance appliance approved that this evaluation system avoiding the simplification and subjectivisation of the evaluation process, was more feasible and practical. What's more, it conquered the difficulties of the comparison between quantitative and qualitative indexes of the train operation diagram, evaluation system will be important for studying deeply method and improving quality of train working diagram.
