Facility Layout Model Based On Pedestrian Generalized Travel Cost And Simulation Evaluation For Passenger-Terminal

Passenger-terminal especially comprehensive passenger-terminal is importantpassenger flow collection and distribution center of ban traffic network. Theplanning and operation management effect of them directly affect the serviceefficiency and level of the whole traffic network. The optimal layout of its innerfacilities is one of the important problems for terminal planning and design. Thispaper based on the project of National Natural Science Foundation of China(No.50978115), focus on the problem of inner facilities layout and simulationevaluation for passenger-terminal has important theoretical research value andpractical applicationsignificance.First, through the research status at home and abroad, this paper gives theclassification and size determination method for inner facilities of passenger-terminal. Through the classification and analysis of pedestrian streamline, the paperdetermines the pedestrian flow between facilities and its distribution in terminal,then lays a quantization foundation for the facilities layout model based on thegeneralizedtrip costof pedestrian from theviewpoint of users.Second, this paper chieflyanalyses and measures the generalized travel cost ofpedestrian in terminal,that is thevalue cost of service receivingtime, queueingtime,walkingtime and waitingtime, then puts forward a new layout model of facilitiesinterminal basedon the generalized travel cost of pedestrian. The model minimizes thegeneralized travel cost of pedestrian in terminal, comprehensively considers thescale,position, shape andthe correlation betweenfacilities, whichis innovative.Andthengives the optimal solutionusing geneticalgorithmbased on Matlab.Once more, this paper tests and evaluates the application effect of the layoutmodel of facilities in passenger-terminal by computer simulation technology, givesthe comparative analysis of influence that the existing and after optimization layoutschemes have on the service level of passenger-terminal,and builds the agent modelof pedestrian using the agent-based modeling and simulation method based on thesoftwareof AnyLogic to control the simulation logic of pedestrian, which includes7logic modules of agent simulation, such like PedInSingleService active object sort depicting the queuing discipline of single pedestrian queue, PedInService activeobject sort depicting the selection rules of multiple pedestrian queues,PedCheckService active object sort depicting the ticket entrance open-notice-servicediscipline. Then, builds the simulation model of passenger terminal system by takethe fixed layout schemes as simulation environment. Finally, establishes the indexsystem of comprehensive passenger-terminal service level evaluation, evaluates XXpassenger terminal as example, which is innovative, and gives the suggestion aboutfacilities optimal layout and improving the service level of passenger terminal,provides decision reference foroptimizing facility layout scheme and improvingthelevel of operation management.
