摘要:
在大小交路一定的情况下，对西安地铁3号线行车组织进行了优化。以最小化乘客等待时间、最大化车辆平均满载率及最小化车辆运行总距离为目标，以发车频率及列车编组为决策变量，构建大小交路列车开行方案多目标优化模型。选用Matlab软件中fminimax函数求解该多目标非线性约束优化问题。优化后,早高峰小时内，乘客的总等待时间基本保持不变，车辆的平均满载率增加17%，列车运行总距离减少 1 305 km，节约牵引能耗约3 027 kWh。
Abstracts:
Based on the given full-length and short-turn routing condition, the traffic organization of Xi′an metro Line 3 is optimized. Aiming at the minimum passenger waiting time, the maximum average full-load rate of trains and the minimum vehicle total running distance, taking the departure frequency and train marshalling as the decision variables, a multi-objective optimization model of train plan is formed. The fminimax function in MATLAB software is used to solve the multi-objective nonlinear constrained optimization problems. The total passenger waiting time of during the morning rush hours remains unchanged, but the average full-load rate of trains is increased by 17%, and the total running distance of trains is reduced by 1 305 kilometers, resulting in the reduction of traction energy consumption by 3 027.6 kWh.
