Research On Schedule Management Of Ticket Vending Machine Renovation Project For G Metro

In recent years，In the domestic economic environment to promote，urbanisationgrows faster, City population become more and more dense that cause the traffic demandincreases. The Metro as fast, comfortable, punctual, efficient traffic began to receiveattention.The automatic fare collection system is the only device that the passengers directlyinteract with.The service quality of Metro is largely depends on its performance. Thestructure can be divided into the clearing system, five levels of line central computersystem, computer system, the station, the ticket station terminal equipment.As a automaticsystem, renewal of equipment and maintenance occupies a large proportion in the AFCsystem construction and operation. For improvement of field equipment operationstability and security, maintenance and upgrading is the most direct means to reducemaintenance burden and improve the operation qualitySo schedule is necessary for Metroautomatic fare collection system renovation projects management.Take the G subway ticket vending machine reconstruction project as an example, theproject reate on many factors as he site,human, equipment, time.Recently, the waste ofresources awalys happen during the project, low efficiency and difficult to guarantee thequality of project makes plan delay.That bring inconvenience to the station site equipmentmaintenance and operation, the management and the staff can not effectively proceed thesituation.Research of this paper depends on the features and status of the ticket vendingmachine reconstruction project. Find out the problems of schedule management, and putforward reasonable suggestions by using the critical path method to find the key nodesand the key factors, then with PERT time planning methods of data analysis. By the end,providing practical solutions and comprehensive suggestions for better schedulemanagement.
