The Research of Train Operation Plan of Aggregate Transport on the Special Requirement

The aggregate rail transport on the special requirement(ARTSR) has a great volume of traffic with a great urgency,which may easily cause the traffic tension of the area,the disruption of working in some periods and the decline of transport efficiency.The paper proposed a method of composing a train operation plan before transport,which can program traffic capacity overall and can make the transport working in order,so it may solve the problem well.By analyzing the requirement of composing a train operation plan,the paper designed a model of the ARTSR.The paper showed a way combining KBS(Knowledge Based System) and CBR(Case Based Ratiocination) to choose the transport routes,and proposed a programmed algorithm based on a method of the fixed train path by the regular characteristic of ARTSR,which could arrange the train schedule on the chosen transport routes.The paper gave an adjusting method to the emergency too.By the model and the algorithm of ARTSR,we had developed a software for it.The paper gave an example to verify the software,and the result showed that the composed train operation plan was reasonable and it could adjust flexibly due to the emergency,so it can give effectively decision support for ARTSR.
