The Mathematic ModeL of ELevator Group ControL and the InteLLigence Group ControL Technique

Elevator transport system is a type of discrete-event dynamic system. In order to improve service quality, tc increase transportation capacity, and to decrease energy consumption of the system, elevator group control technology is adopted. Various heuristic optimization methods based on AI technology have been used to optimize the performance indexes, such as the average response time of hall calls, the average waiting time, the long waiting time percentage, and average riding time, etc. Controlling elevator group is in nature a multi-objective scheduling problem. The mathematic model of the elevator group control problem is represented, and the characteristics and the performance indexes to be optimized of the problem are analyzed. The state-of-the-art of applying AI to solve elevator group control problem is reviewed, and prospective research issues in the near future are proposed.
