基于排队论的电梯交通系统阈值控制方式

目的寻找电梯交通系统最佳调度控制策略.方法将排队论理论应用到电梯群控系统中,对电梯上升高峰期间运行参数进行分析,讨论电梯乘客人数与平均候梯时间、乘客到达率等变量之间的关系,提出一种基于M/Mr/1排队系统模型的阈值策略控制方法.结果借助计算机在不同情况下对所提出方法进行了仿真试验,并以真实建筑物的电梯数据为例,采用不同的调度控制方法对不同的性能指标进行了对比分析,验证了排队论阈值方法在电梯群控系统中应用的可行性.结论试验结果表明,基于排队论的阈值方法是一种在电梯上升高峰期间理论合理、实施性较强的调度控制方法.

Elevator Traffic System Threshold Control Mode Based on the Queue Theory

In order to find out the optimal control strategy of elevator traffic system,the fastigium running parameters are analyzed,and the relationship between elevator passenger number,the average awaiting time,and the arrival ratio are discussed.A new threshold strategy control method based on the M/Mr/1 queue model is presented and applied in the elevator group control system.The real observation data are used for simulation tests.The new method combines the advantages of the two methods so that it could well meet the needs for elevator running.And the application of this method to the elevator group dispatch is studied in detail.The simulation results show that the threshold method has good performance.It proves that the method is a better control strategy in elevator fastigium.
