The multi-agent modeling and calculated analysis of shop logistics scheduling in the manufacturing enterprises

In this paper, the multi-agent model about shop logistics is set up. This model has 8 agents: raw materials stock agent, process agent, testing agent, transition agent, production information agent, scheduling agent, process agent and stock agent. The scheduling agent has three subagents: manager agent (MA), resource agent (RA) and part agent (PA). MA, PA and RA are communicating equally that guarantees agility of the whole MAS system. The part tasks pass between MA, RA and PA as an integer, which can guarantee the consistency of the data. We use a detailed example about shop logistics scheduling in a semiconductor company to explain the principle. In this example, we use two scheduling strategies: FCFS and SPT. The result data indicates that the average flow time and lingering ratio are changed using different strategy. It is proms that the multi-agent scheduling is useful.
