Non resort Operating Parameter Model for Technical Station's Train Formation Plan with Locomotive Extended Routing

LIN Bo liang (School of Traffic and Transportation, Northern Jiaotong University, Beijing 100044, China)  
Based on the analysis of the yard cost parameter which is a time cost saved by every car for passing through a technical station without reclassification, a drawback is discovered about yard cost parameter. Considering the fact that trains are not technically inspected at every yard on their trip from origin to destination, we establish a relation between trains connect and total non reclassification operating time cost because of technical inspection and change of locomotives. The traditional yard cost parameter is replaced by non resort operating cost and the fixed delay suffered by cars in the yard due to operations: classification, make up. As a result, a mathematical model of the train formation plan with non resort operating parameter time cost has been developed for railroad operating problem with locomotive extended routing (NTFP). It is obviously that the NTFP model is more suitable to incorporate the characteristics of real life applications.
