Dynamic dispatching of elevators in elevator group control system with time-based floor preference

Abstract

Elevator Group Control System (EGCS) has a significant role in the transportation system of buildings. This study presents an elevator group dynamic even and odd floor preference approach based on the real-time passenger traffic to overcome the difficulty of using elevators in the up peak and down-peak traffic mode. The proposed system framework divides building floors as even and odd based on the floor number, some lifts allocated for even numbered floors and some for odd floors. Even numbered lifts are responsible for serving calls of even floors, and odd number lifts are responsible for serving calls of odd floors. Proposed study uses time-based floor preference logic for dynamic allocation of elevators. The primary motive of the proposed research study is to reduce the passengers traveling time, average-waiting time and improve overall system performance in up-peak traffic and down-peak traffic conditions. The time-based floor preference logic used for dynamic allocation of elevators significantly minimizes the waiting time and traveling time of passengers.
