Optimum Dispatching of Elevator Banks for Elevator Traffic System Based on Bi-level Programming Model

Optimum dispatching of elevator banks is essential to elevator traffic system.Based on up peak traffic condition,an optimization multiple-objective mathematical mode of elevator banking in the high-rise is proposed.A new method employing bi-level programming model is presented to deal with a specific multiple-objective question.The objective function is optimized by optimizing the weight vector,and the appropriate decision variables are obtained.This approach overcome the drawback of the conventional method of determining weight value by preference in dealing with linear combination weighted method,meanwhile,the optimal solution is achieved by analyzing the cost concerning building layout for the optimal solution.The research is of great applied significance both in the elevator vertical traffic system design of the high-rise,and in the implementation of elevator group control systems.Simulation results show the validity of the proposed method.
