5.2.2 Equipment occupancy list
As a basic rule an apparatus can at a given time only be involved in the
production of a single batch. BATCH flexible’s batch control manages
equipment allocation in on-line operation in such a way that an apparatus
(identified by the UNIT block) can only be occupied by one batch. The
apparatus is seized by batch control when the recipe starts or while it is in
progress, when the first AF starts with this apparatus. Batch control prevents
duplicate allocations of the apparatus in on-line operation – in other words,
other batches which require the apparatus must wait until the occupying
batch releases the apparatus.
In order to exclude or reduce waiting periods of this type even during the
planning phase, batch planning manages the planned equipment occupancy
times and displays possible conflicts during on-line processing of the batches
as planned multiple allocations (see Chapter 6.5).

Figure 5-4 Equipment occupancy list
The ’Equipment occupancy’ window presents an overview of all of the
apparatuses for which batches have been created. Via the ’View’ menu this
overview is presented as a tree diagram of the batches (in the lefthand pane)
as well as the batch list associated with the selected apparatus.
