英文摘要

      In this paper, a multi-objective optimization model is proposed based on the operation rules for the group elevators working in an equal interval mode. Accordingly, an optimized dispatching strategy is established to achieve the shortest average waiting time of passengers, which is also primary optimization target. For such we formulate the dynamic performance evaluation of group elevators’ operation with the indexes such as passengers’ waiting time, taking-on service time, elevator-cars’ full-load-rate and up-down energy consumption. Considering the randomness of elevator passengers’ flow, the rules and algorithm of equal interval dispatching for passengers’ waiting time are developed to implement the dynamic scheduling method of multi-objective optimization of the group elevators. Finally, in simulation and testing experiment, the results show that the proposed method reduces the average waiting time of passengers by 13.1% and improves the performance of group elevator system, which is comparing with the traditional shortest distance scheduling algorithm.
