Abstract

The real estate industry has been experiencing immense growth, evident from the growing number of tall buildings in cities and urban areas. In buildings, elevators play a vital role in carrying people to their destined floors. However, there is a need to improve the dispatching systems of these elevators that affect waiting and journey times of the users, as well as reliability and sustainability (economic and environmental) of the elevators systems. This paper reviews a number of widely used elevator dispatching systems and their underlying algorithms including Estimated Time to Dispatch (ETD), Destination Control System (DCS), and CompassPlus Destination System (CDS). A qualitative methodology was adopted for this study. From survey of literature, a number performance criterion for elevator systems was used to make a comparison amongst the elevator-dispatching systems. In addition, our study shows that a research into human behavioral aspect and (economic and environmental) sustainability are two other pertinent factors that should be considered whilst modelling dispatching systems for elevators.
