【 摘 要 】

Adjustment of train disintegrating and classifying schemes in the marshalling station is the key of wagon-flow allocating optimization. The train disintegration and classification sequence is subjected to the priority of time departure. Under above-mentioned arrangement, the priority of time departure scheme is difficult to ensure the full-load of each departure train. On the basis of analyzing for interval time of departure train, waiting departure time and the relation among each time parameter, several concepts will be given. Using the method of single machine scheduling problem is to minimize the influence for classification and disintegration sequence adjustment. The necessary conditions of adjustment can be obtained and the influence after adjustment is shown by graphic deduction. Finally, the conception of time pass theory is provided. The rationality of this method has been proved by a case study. This method lays a foundation for adjustment of train classification and disintegration sequences.
