Elements of Scheduled Lead Times

When scheduling production operations, four elements of lead time are used in the calculations:

·     Move.  The time taken to move components from an operation in one workcenter to the next operation in a different workcenter.

·     Queue.  The time taken to move components from one operation to the next in the same workcenter.

·     Setup.  The time to prepare an operation.

·     Run.  The actual elapsed run time for an operation.

The move and queue times are a buffer between consecutive operations.  Move and queue times are mutually exclusive.  They are applied as an offset before the start date of the next operation is calculated.
