Research on Intelligent Compilation of Locomotive Turnover Diagram
The locomotive turnover diagram is a graphical representation of the operation of locomotives in various sections,compiled based on the train operation diagram.In recent years,with the rapid development of informatization,digitization and intelligence,the intelligent compilation of locomotive turnover diagrams has become a hot research topic.The same type of lo-comotive can break its routing restrictions when operating in different sections,and the locomotive can rotate freely between several routes.The problem of compiling locomotive turnover maps is transformed into a multi traveling salesman problem,and the idea of arrays is used to intelligently compile locomotive turnover maps.The train operation diagram is drawn in a ten-grid coordinate system.An Array function is established based on the arrival and departure times of the train,the basic turnover di-agram is outlined,and the complete locomotive turnover diagram can be obtained.The test results show that the locomotive turnover chart compiled using this method has the least number of locomotives used and the utilization of each locomotive is rel-atively balanced,which meets the requirements for the optimality and balance of the locomotive turnover chart.The research results provide theoretical support and application reference for the intelligent compilation of locomotive turnover diagrams.
