public class DemandProcess extends SimProcess
Entrepot where the products to be sold are stored, the random
number distribution to determine the quantity of demanded products, the rate
(frequenzy) also a random number distribution, at which the demand occurs.
Once the DemandProcess has obtained the products, they are consumed and will
leave the simulated system for ever. Actually they will be destroyed as the
the garbage collector will get them. Internally CustomerProcesss
es are set up and initialized, which are the ones actually fetching the
products from the Entrepot. But this is done automatically,
so the user does not have to care about it.| Constructor and Description |

getDemandInterval()
Returns the random number distribution determining the intervals in which
the demand occurs.

lifeCycle()
The DemandProcess is fetching in certain intervals a certain quantity of
products from the given
Entrepot and destroys them. |

setDemandInterval(NumericalDist<?> newDemandInterval)
Sets the intervals in which the demand occurs to the new given random
number distribution.
|
void |
setDemandQuantity(NumericalDist<java.lang.Long> newDemandQuantity)
Sets the demand (quantity) to the new given random number distribution.

serves as a drain for the finished products. To prevent this process from
being blocked waiting in the queue of the Entrepot, it
will instantiate CustomerProcess es which will actually
