The Use of Numerical Methods to Evaluate the Performance of Up Peak Group Control Algorithms

摘要

Incoming traffic group control algorithms are an important aspect of elevator traffic management. In order to allow an objective repeatable comparison of different up peak traffic group control algorithms, it is necessary to have an evaluation mechanism of their effectiveness. The use of equations in evaluating elevator group control algorithms has been very limited. Simulation has traditionally been the tool that is used to assess and compare elevator group control algorithms. However, simulation suffers from a number of disadvantages such as lack of repeatability, reproducibility and transparency. Numerical methods are very effective in providing a mechanism for objectively assessing and comparing elevator group control algorithms. This paper provides an overview of the use of such numerical methods in assessing the efficacy of different group control algorithms. It shows how the method can be used to expose the group controller to different scenarios, and then finding an optimum solution.
