Storage Tab

Capacity The maximum number of entities that can be in the storage at one time. Use the keyword “Infinite” for an unlimited amount of storage.
Entity Choose the name of the entity that will be stored at the storage shape. If you have multiple storage shapes stacked into a storage block, each shape must have a unique entity.
Initial Level Enter the number of entities that will be in the storage when the simulation starts. If the Initial Level is less than the reorder quantity then an initial order will be automatically triggered at the beginning of the simulation.

The trigger controls when more entities will be ordered according to the Order options

By Level When the trigger is defined By Level, an entity order will occur when the quantity of entities at the storage shape drops below the level defined.
By Time An order will occur according to the simulation clock and not the quantity of entities at the storage.

Level (available when By Type is Level) When the quantity of entities at the storage drops to this value or less, an order will occur.
First Time (available when By Type is Time) The first order will occur when the simulation clock reaches this time. If this field is left blank then the first occurrence will be based upon the time in the Frequency field.
Frequency (available when By Type is Time) Defines how often orders will occur after the first time.

An order causes entities to arrive with an Ordered Arrival or route with a Send Routing to a storage or activity when the order is triggered.

Entity Select the entity to be ordered. This does not need to be the same entity that is in the storage. However, the entity must become the storage entity somewhere in the process prior to arriving at the storage in order to be allowed into the storage without error. This can be accomplished, for example, by renaming the entity or attaching the ordered entity to another entity with the proper name.
Qty/Up-to Qty If the By Type is defined as Level, then this is the quantity of entities that are reordered when the total inventory drops below the trigger level. If the By Type is defined as Time, then the quantity entities that are reordered is determined by subtracting the total inventory from the Up-to quantity defined..
Source Select where entities are to be ordered to. Entities do not need to be ordered to the storage shape where the order is defined, but rather an order can be performed at any ordered arrival or send routing.
