Elevator Group Control with Destination Hall Call Registration

A Comparison between Immediate and Nonimmediate Allocation Guidance Systems

Abstract

In this paper we consider the group control problem of a multiple-car elevator system with destination hall call registration. The destination hall call registration system is such a system that passengers can register their destination floors directly at elevator halls. We treat this problem as dynamic optimization problems, where two types of guidance systems are considered; immediate and nonimmediate allocation guidance systems. By computational experiments, we show that the operation efficiency of the multiple-car elevator system can be improved by destination hall call registration and that the nonimmediate allocation guidance system yields better results than immediate one.
