Production Order Planning of Generic Items

The generic routing for configurable job shop items differs from the normal routing. Which operations are used in the routing, depends on the configuration.

If the configurable item is configured using the:

Example

Two operations might be exclusive: either operation 10 is selected, or operation 20. As a result, a sequence of operations is not required.

Therefore, the operation of a generic routing has several parameters for planning:

  • Planned Production Time
  • Planning Percentage
  • Lead Time Offset

For the lead time, the planning percentage is taken into account.

Operation lead time = planned production time * planning percentage

The lead time offset is used to determine the start of the operation sequence.

Offsetting production schedules

Offsetting for production schedules is based on the item production model. The following production model data is used in lead time planning:

  • The work cell where the item is produced
  • The order plan lead time
  • The order plan lead time unit (hours or days)
  • The order plan quantity
lead time in hours or days = Order Plan Lead Time * Order Quantity/Order Plan Quantity

The calculated lead time is planned backwards starting with the finish date, using the work cell calendar.
