Revised Design Calculations of Lift Systems

Abstract

For sufficient transportation capacity and passengers comfort and convenience, it is very important to design the suitable lift systems (e. g., the appropriate number of cages, velocity, capacity etc.) using a model which describes real elevator movements.
The procedure used in conventional design calculations for office buildings is to determine the transportation capacity for the up-peak traffic situation using a, simple passengers arrival model.
This paper presents a new design calculations using balanced traffic model, which can deal with the elevetor movements considering passengers arrival rate. As some performance indexes to evaluate the quality of service can be calculated by using this model, lift system designers can determine the appropriate lift facilities as to satisfy their goals. The validity of the propsed model is also shown by comparing with the measured data in real lift systems.
