The initial capacity of capacity resources is indicated by the value of the Startup capacity resource attribute. If this attribute has not been specified, 0 is added for the Current capacity attribute as soon as the simulation is started. The capacity of a capacity resource can be changed in three ways. It can be permanently increased, permanently reduced, or temporarily reduced while the function is being carried out.
Permanent increase of the capacity of capacity resources
The capacity of a capacity resource is increased if it is linked to a function via a produces connection and the function is carried out. You can control the quantity by which it is increased using the Quantity connection attribute of the Simulation attribute type group. If the Quantity attribute has not been specified, the capacity of the resource is not increased when the function is carried out. The function is not carried out if this causes the capacity of the resource to increase above the value specified in the Maximum capacity attribute.
Permanent reduction of the capacity of capacity resources
The capacity of a capacity resource is reduced if it is linked to a function via the is consumed by connection and the function is carried out. You can control the quantity by which it is reduced using the Quantity connection attribute of the Simulation attribute type group. If the Quantity attribute has not been specified, the capacity of the resource is not reduced when the function is carried out. The function is not carried out if this causes the capacity of the resource to fall below the value specified in the Minimum capacity attribute.
Temporary reduction of the capacity of capacity resources
The capacity of a capacity resource is temporarily reduced if it is linked to a function via the is used by connection. You can control the quantity by which it is reduced using the Quantity connection attribute of the Simulation attribute type group. This reduction is only effective while the function is being carried out. Once the execution of the function is complete, the original capacity quantity is available again. The function is not carried out if this causes the capacity of the resource to fall below the value specified in the Minimum capacity attribute.
