In batch processing sytem, baggage enters the system in batches. System scheduler determines the state of the gates. Opening the gate between an input and the collecting conveyor releases the batch into the conveyor. A batch processing type BHS resembles a railroad system where a batch corresponds to a train. There are some advantages to grouping baggage in batches.
Baggage is processed in groups rather then individually.
This reduces the amount of information processed. For example, groups of baggage, instead of individual items, are tracked. Routing is simpler because groups are fewer than items. A simple system made of gates between the collecting and the output conveyor can manage the routing. Gates control eliminates traffic control for the incoming items.
