A Metro Company Train Overhaul Project Schedule Management Research

A metro company line5is use Linear motor train carrier systems. line5train core partslike traction system, braking system, and train bogie adopts foreign advanced technology.Since December26,2009opening, running to2013the total mileage has reached the overhaul,all the main parts of the train need to performance testing and dismantling overhaul andmaintenance, to restore the main performance index of the train, eliminate the train operationrisk, extend the life of the train.Linear motor train imported a lot of the core components ofthe, while Beijing, Guangzhou has used, but because only recent years put into operation.linear motor train overhaul is not much. more not strictly according to the concept of projectmanagement standard to carry out overhaul work precedent, therefore, the line5trainoverhaul project planning, implementation and control. In domestic not have very matureexperience to follow.This article first research train overhaul project process, management type, characteristicand the existing problems, and obtained train overhaul project schedule establishment andoptimization research direction, starting from the process to comb of train overhaul project,according to each working procedure consumption of resources, and A metro companyoverhaul shop can use of resources, use PERT establish train overhaul project preliminaryschedule. Procedure time again by shortening the critical path methods(CPM) and rationalallocation of resources, further optimization the train overhaul project schedule, according tothe project management method to compile the reasonable A subway company trainoverhauling project management schedule. Allow A subway company frame project schedulefrom heaven from889to767days, obvious optimization results were obtained.In order to ensure when the train overhaul project in lag,, through scientific crashing, canin the case of cost savings as far as possible finish the overhaul project in schedule, this paperalso studied the crashing problem in train overhaul project, confirmed the A metro companytrain overhaul project optimum crashing strategy, and established A subway companyoverhaul project progress other management safeguard measures, In case of a reasonableincrease in resources for crashing, and from the767day period can be further shortened to660days.In addition, in order to schedule more effective implementation of the A Metro Inc trainframe repair project, strengthen process management, according to the frame repair projectthe actual situation, starting from the perspective of fine management, the spirit of"professional, scientific quantification" principle, from5aspects,12developed A Metro Inc train frame concrete measures fine management of repair project.In this paper, the research for the future of the linear motor train train overhaul projectsplay a good role and guiding significance to the case.
