Based On Multi-agent Distributed Train Operation Simulation System

As an important kind of transportation, railway has a great significance to the expansion of our national economy. We should apply stimulation to the train operation system, so that we can use it to put forward the organization plans and modification plans of trains operation, to evaluate the various organization plans of trains operation, and to support the scientific decisions.A train operation system based on a single computer is of low efficiency. And it can not perfectly represent the real system. Simultaneously, Multi-agent framework can well avoid conflict and deadlock and improve the system efficiency. From what I have mentioned above, in the paper, we start the research of distributed train operation simulation system based on multi agents on the ground of the model TGOSOPS.To begin with, we talk over the model TGOSOPS and analyze it. Then, we build six kinds of agents such as: TrainAgent, RequestAgent, ControlAgent, and so on. And we construct a train operation distributed simulation system based on multi-agent. Then we discuss the concrete structure of agents above and all possible methods in the programming of the system. Subsequently, we dwell on the analyzing of all kinds of statistics and the communication situation among the agents. Then in order to analyze the efficiency and security of the system, we introduce the modeling and analyzing method of the collaboration of multi-Agent system based on Petri net. According to it we prove the design of agent collaboration relation is correct and rational.The framework of the distributed train operation simulation system of the paper is clear, frank and easy to be programmed. And it is easy to be transplanted. Consequently we can use it to many other distributing systems such as other modes of transportation, automatic control of industry and mine, and military simulation.
