Modeling and scheduling elevator group control system based on MAS and negotiation mechanism of agents

Distributed elevator group control system (EGCS) based on multi-agent system can overcome the computing bottleneck existed in collective EGCS. The distributed EGCS is composed of C-agent, HC-agent and M-agent, which corresponds to elevator car, group controller, and a virtual management unit respectively. The architecture of a reticulate distributed EGCS is proposed. The quoting algorithms of C-agent based on market-like model and the evaluation algorithm of HC-agent are described in detail, and the overall optimization mechanism of distributed EGCS is discussed.
