In this work studying of the strategy of preventive maintenance in the station
was conducted and spatial planning combustion chambers inspection (CI) by using
the critical path method which an important tools for the planning of maintenance
work was developed.
In order to have accurate results for calculating early, latest, delay, and slack times, and
determining 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 preventive
maintenance for combustion chambers inspection by two days. Furthermore, two
other days can be saved if the time for some of critical activities was crashed.
