摘　　要：合理的区段管内车流组织是提高铁路车流组织水平、设施运用效率和区间通过能力等的重要保证。通过分析影响车流组织的因素 ,合理地描述了区段管内车流组织的费用 ,建立了以集结车小时、停留车小时和停站次数最小化的优化模型 ,并给出一种优化求解算法。实际运用表明 ,优化模型优化运算效率高 ,求解的列车开行方案令人满意。Rational organization of location wagon flow with district is an importation guarantee of improving railway organization and operation efficiency. The factor affecting organization of wagon flow was analyzed, and the cost of organization of local wagon flow with district was rationally described. An optimization model was established based on minimization of assembly wagon-hours, stopping wagon-hours and quantities of stopping. An optimized algorithm was presented to solve the model. The practical application shows the calculation operates efficiently, and the wagon flow organization project is rational. 9 refs.
