Multi-car multi-shaft elevator system design problem and a solution method based on CPN tools

Abstract

In this paper, we tackle a problem that designs multi-car multi-shaft elevator systems. We first formalize the problem as a multi-objective optimization problem. Then to solve the problem, we propose a method utilizing a high-level Petri net tool, CPN Tools. We apply the proposed method to 24 instances of the problem, and then discuss those results.
