---+ Editing Batch Modules

_Batch_ modules can be added to the flowchart view via dragging and dropping (see [[EditingCreateModules][Editing Create Modules]] for a demonstration) and edited by double clicking on the module.

Batch modules are the grouping mechanism for Arena simulation models. The _Type_ of batch must be specified as either =permentant= or =temporary=. Temporary batches must later be split using a _Separate_ module. The _Size_ is the number of entities to be matched together. The _Rule_ refers to whether entities may be matched together in order of arrival or based on an specified attribute. Entities arriving at the _Batch_ module are placed in a queue until the required number of entities has accumulated. Once accumulated, a new _Representative Entity_ is created.

A good example of a Batch module is collecting a number of parcels before embarking on a courier delivery run (see the flash movie titled "Adding Deliveries to Courier Model " in the [[CourierServiceModel][Courier Service Model]] ). A printscreen of the _Batch_ module used in this example is shown below.
