Shut down management - Plant Maintenance

The process of project management is generally applied to a maintenance shutdown in coal handling plant of thermal power stations. The critical path method (CPM) or sometimes a Gantt charts is used for planning shut down. But it is observed that existing method is not sufficient and foolproof for such type of work. This paper covers a new
