Real-time scheduling for elevator group systems

The traditional assignment approaches for elevator group systems, which are simple and rough, are only fit for low-rise buildings. Hence, they are not suitable in the high-rise buildings with complex traffic requests. In this article, a so-called Score Index Assignment (SIA) approach is proposed to design the real-time scheduling for elevator group systems. Simulation results are given to show that the SIA approach can improve the total service performance of the elevator group system subjected to uncertainties. The SIA approach can fit in any different traffic request conditions by tuning the control (assignment) parameters in the so-called total service evaluation index function of elevator.
