The Design And Research Of Emergency Disposal Simulation For Fully Automatic Operation System Based On MAS

Fully automatic operation system is a new generation of urban rail transiting system,which is based on the purpose of improving the service level through modern information technology.It has been considered as one of the main developing direction in the international environment.The application of high level automation system will make the man-machine function be redistributed,especially when there is an emergency in its operation,the emergency disposal which is used by operating unit is different from the traditional one,therefore,it is necessary to study the emergency response strategy that is suitable for FAO.Emergency disposal is an important part in the process of rail transit operation,the disposal strategy usually requires the joint development of the professional experience.However,because of the complexity of urban rail transit,it is difficult to drill in the real emergency scene,so we need to construct particular simulation environment to verify the strategies.According to this requirement,this paper will choose suitable methods so as to build the simulation platform for emergency disposal on the basis of the characteristic in emergency disposal of fully automatic operation system,in order to finish the design of emergency response simulation platform and giving a scientific evaluation system,achieving the verification analysis in emergency strategies.The research work of this paper listed as follows:(1)According to the structural features of fully automatic operation system,analyzing the changes in system device and organizational workers.Understanding the operating process of rail transit under the condition of fully automatic operation system,deeply refining the emergency scene which has simulation significance and to make the contents as well as needs clearly.(2)Researching on the modeling method of Multi-Agent System(MAS),taking the participating objects in emergency disposal abstracted into six Agents:central scheduling,passenger,train,site supervisor and line.At the same time,constructing three layers of MAS emergency disposal simulation architecture with center,bus station and train.According to relevant basic principle,defining the attribute,decision-making and action of every Agent,so as to determine the interaction and contents between Agent.Finally,finish the construction in simulation model of full automatic operation system.(3)Based on the MAS model and the data of Beijing Yanfang line,using the Anylogic simulation tools to exploit emergency response simulation platform for fully automatic operation system.The platform has good man-machine interface,it can achieve several functions:controlling emergency process,tracking interactive information dynamically,showing response process by 3D display and critical data management function.(4)Combining with the output results of simulation platform,defining and quantizing the index in concrete way,using analytic hierarchy process to construct the emergency strategy evaluation system in fully automatic operation system.Taking the rescue situation as an example,analyzing emergency strategy and combining the evaluation results to put forward decision support and advice for this operation.
