Application of Critica! Chain Project Scheduling Theory in Power Plant Electrical Equipment Maintenance

摘要

The critical chain project management theory(CCPM) combining the critical chain technology and resource-constrained project scheduling problem (RCPSP) is an important innovation of project control methods, and it's widely used to optimize the project duration recently. In this paper the theory presented is applied to the maintenance period arrangements of power plant electrical equipment, and a mathematical model of optimizing the maintenance period is established. Then an improved heuristic algorithm is designed and used to establish equipment maintenance precedence network. On this basis, a new identification method of maintenance network based on critical chain is proposed. Finally, it's verified with a numerical example that the method proposed can effectively shorten the maintenance period of power plant electrical equipment.
