Research on Schedule Planning Management of Railway Construction Project Based on CAS

Abstract

The CPM and PERT are the most popularly used underlying method of schedule planning of construction project, Problematically, CPM and PERT depend on the experiences of project manager, which is not true in railway construction project. A huge deviation occurs between the actual progress and planned schedule. This leads to unreasonable allocation of resources and cost increment. Referring to the characteristics of schedule planning of railway construction projects, we proposed schedule planning conceptual model of railway construction project based on CAS. The model consists of three parts. They are master schedule, forecasting planning and operational planning. Forecasting planning is produced by master schedule and adjusted by operational planning dynamically. In addition, RBF neutral network is employed to improve the accuracy of master schedule. The paper provides novel viewpoint and idea for project management of railway construction.
