Field help (PSPTIMPOPS)

Post operation, or post run time is a 'deadline' that occurs after waiting time. It is non-productive time, typically 'transfer time', or a transition period from one work center to the next work center that occurs after a process has been completed on a machine and until the machine can next be used.

 Waiting time is always expressed in hours. It does not use the time unit defined in the routing header (field Time unit). Waiting time is not applied to the work center load.

If operator time is required for an operation during the allowed post run time you should add a new operation to this routing. An operator might be required for example, for the transportation or carriage, or the transition between two work centers. The additional operation must be for the appropriate resource type, such as 'carrier'.

When scheduling time for these resources if, for example, a work center (machine or labor) runs from 08:00-12:00 and 13:00-17:00 with a break for one hour between 12:00-13:00:

• When scheduling post run time a neutral 24 hour calendar for the defined resource is applied. Post run time is not, therefore, interrupted by the one hour break.
• When scheduling time for the additional resource the calendar for the defined resource is applied. Time will be interrupted by the one hour break.

If the operation requires an 'emergency release', a reduction coefficient can be assigned that makes it possible to completely remove any post run time.

 When scheduling time for these resources, if both waiting time and post run (post operation) time has been declared for the operation only the largest of the two values is used.

If you use Production scheduler for detailed planning, if both waiting time and post run (post operation) time has been declared for the operation both values are used in the scheduling.

The 'published plan' (the planner's confirmed schedule) includes both times as part of the scheduled operation and in the reported scheduling data.

 Activity code POPS must be activated to use Production Scheduler for detailed scheduling.
