Use of Critical path method inmaintenance planning of an electric power station


In this work studying of the strategy of preventive maintenance in the stationwas conducted and spatial planning combustion chambers inspection (CI) by usingthe critical path method which an important tools for the planning of maintenancework was developed.In order to have accurate results for calculating early, latest, delay, and slack times, anddetermining the critical path time (WINQSB) Software which contain(CPM-BERT) programs has been used..The most important results of this study is in reducing the time of preventivemaintenance for combustion chambers inspection by two days. Furthermore, twoother days can be saved if the time for some of critical activities was crashed.
