4 • THE ADVANCED PROCESS PANEL PROMPTS Prompt Name Type Queue Name Starting Value Ending Value Search Condition Description Unique module identifier displayed on the module shape. Determination of what will be searched. Search options include entities in a queue, entities within a group (batch) or some expression(s). Name of the queue that will be searched. Applies only when the Type is Search a Queue. Starting rank in the queue or group or starting value for J in an expression. Ending rank in the queue or group or ending value for J in an expression. Condition containing the index J for searching expressions or containing an attribute name(s) for searching queues or batches. Signal module DESCRIPTION The Signal module sends a signal value to each Hold module in the model set to Wait for Signal and releases the maximum specified number of entities. When an entity arrives at a Signal module, the signal is evaluated and the signal code is sent. At this time, entities at Hold modules that are waiting for the same signal are removed from their queues. The entity sending the signal continues processing until it encounters a delay, enters a queue, or is disposed. TYPICAL USES • Analyzing traffic patterns at an intersection (signal when the light turns green) • Signaling an operator to complete an order that was waiting for a component part PROMPTS Prompt Name Signal Value Limit Description Unique module identifier displayed on the module shape. Value of the signal to be sent to entities in Hold modules. Maximum number of entities that are to be released from any Hold modules when the signal is received. 65

GETTING STARTED WITH ARENA Store module DESCRIPTION The Store module adds an entity to storage. The Unstore module may then be used to remove the entity from the storage. When an entity arrives at the Store module, the storage specified is incremented, and the entity immediately moves to the next module in the model. Storages are useful for displaying entity animation while an entity undergoes processing in other modules. Additionally, statistics may be kept on the number of entities in storage. TYPICAL USES • Animating a part through a number of delay operations (load, setup, process, unload) • Tracking the number of customers within a grocery store (place in storage upon entry) PROMPTS Prompt Name Type Storage Name Set Name Set Index Attribute Expression Description Unique module identifier displayed on the module shape. Method of specifying the storage name as a Storage, Set, Attribute, or Expression. Name of the storage to which the entity will be added. Applies only when the Type is Storage. Name of the storage set from which the storage is to be selected. Applies only when the Type is Set. Index into the defined storage set that contains the desired storage name. Applies only when the Type is Set. Name of the attribute whose value contains the storage. Applies only when the Type is Attribute. Expression that is evaluated to the storage into which the entity is placed. Applies only when the Type is Expression. 66
