Based On Critical Chain Schedule Management Research Of Technology Of A Highway Maintenance Engineering

Since the reform and opening up, China's highway construction has been vigorous development. Because use fixed number of year expiration, traffic volume and weight rapid growth and other causes of pavement damage, at present, there are a large number of countries gradually into the overhaul period. " Twelfth Five-Year Plan" period, the state will continue to increase the traffic infrastructure investment. For the upcoming National Highway overhaul peak, to follow the implementation of the project to provide reference, plans to combine the Luoding segment of National Highway 324 on highway overhaul overhaul project project management carries on the discussion and the research.Because the traditional project schedule planning method to float float zero or minimal work package as a key chain, considering only the time constraints, therefore, in practical application is easy to cause the project schedule delay. Critical chain method in the theory of constraints ( TOC ) on the basis of the system, it pays attention to the project, considering the project staff's psychological factors and the project schedule the resource restriction in the development of a project schedule management method, using the buffer on the project schedule optimization and monitoring.In this paper, a review of related literature under the premise, can go abroad 324 lines Luo ding paragraph overhaul project schedule management problems, analysis of the Luo ding section of NO 324 National Highway overhaul project status. Thus introducing critical chain method, can solve the time more uncertain factors, process the complicated relationship between the national highway overhaul project schedule management. At last establishes associated buffer management mechanism, to solve the overhaul project management problems, and through the mechanism of project schedule management. Practice shows that, the critical chain technology, in heavy repair of highway project and program management has a very good application prospect. Finally, summed up the critical chain technique to other overhaul project management aspects of the enlightenment.
