Every operation in planned and production orders is divided into operation segments:

• Queue time

• Setup time

• Processing time

• Teardown time

• Wait time

The sum of the setup time, the processing time and the teardown time forms the execution time (see following graphic).

The system calculates dates for all the above operation segments.

The system generates relationships automatically. The system links the operations for every sequence in the order using relationships. It links them in ascending order of operation number. You must explicitly maintain the relationships between the operation sequences.

In planned and production orders the move time represents the duration of the relationships.

The system takes the floats before and after production into account for planned orders and production orders. The float before production is between the order start date and the first operation, the float after production between the finish date of the last operation and the order finish date.
