铁路货物列车编组计划的半定量分析及满意度

A Semi-Quantitative and Satisfactory-Oriented Method on Train Formation Plan

对铁路货物列车编组计划系统的特征进行了分析,对方案的优选从车小时计算拓宽到 多方位控制;将开行直达列车的3个条件应用到对整个方案进行分析,给出了新的概念,从而界 定了满意解集合;将方案的优化从求“最优解”转换为求“满意解”,并提出了满意度的评价公式及方案的稳定性分析.

Based on the analysis to the characteristics of freight train formation plan system, the paper advances an optimal procedure on criteria, alternative control and through train scheme, a set of satisfactory solutions has thus been defined that makes the target to be a process to search a satisfactory solution instead of the optimal one as in other tranditional methods. It also analyzes the stability of targets and practical solutions.
