Middleware and shift generation

The MES middleware that is currently handling maintenance services will generate shifts for entities based on the shift patterns to which the entities are assigned or inherit from a parent entity.

Each shift pattern includes one or more shifts that make up a shift schedule. Shift patterns and schedules are defined in MES Client. This allows the start and end time of each shift to be determined independently for any set of entities. Note that shifts in MES are not directly associated with personnel.
