城市轨道交通人工作业日的夜间施工线路封锁方案优化

Optimization of Metro Line Blocking Scheme at Night on the Manual Day for Rail Transit Staff

介绍了目前城市轨道交通使用的线路封锁方案,并指出其缺陷。根据人工作业日给定的施工需求,制定以封锁次数最少为目标、施工按时执行为约束条件的线路封锁方案模型,通过分析封锁区域、封锁时间与封锁次数的关系得到优化算法。以上海轨道交通8号线人工作业日为例进行算法验证,结果表明该算法弥补了目前线路封锁方案的缺陷,达到"以机替人"的智能管控效果。

In this paper, the current urban rail transit line blocking scheme is introduced, the defects of which are pointed out. According to the given construction requirements on the manual day, a line blocking scheme model is established, which takes the least blocking time as the target, the construction on time as the constraint condition. Based on an analysis of the relationship between blockade region, blocking time and blockade number, an optimized algorithm is built up. At last, Shanghai metro Line 8 is taken as an example to verify the algorithm, the result shows that the algorithm could achieve the effect of intelligent management by making up the defects in current line blocking schemes.
