Scheduling equipment for regular maintenance so that it is unavailable for use during certain periods. (If maintenance is done during off hours, it can be safely ignored in the model.)
Suggested Technique
1. Assign a shift to the resource to indicate scheduled downtime (for maintenance or other purposes). For information on creating and assigning shifts, see Defining & Editing Shift & Break Blocks.
Whenever possible, use the shift schedule for scheduled interruptions.
