Constructor Detail

RestockProcessQT

public RestockProcessQT(Model owner,
                        java.lang.String name,
                        long q,
                        TimeSpan t,
                        Stock client,
                        NumericalDist<?> lt,
                        boolean showInTrace)

Constructs a RestockProcessQT which restocks a client Stock after a fixed time period with a fixed quantity of units. The lead time (time gap between placement and receipt of an order) will be given as a real random number distribution.

Parameters:

owner - Model : The model this RestockProcessQT is associated to

name - java.lang.String : The name of the RestockProcessQT

q - long : The quantity supplied to the Stock with every order.

t - TimeSpan : The time period between the inventory reviews (in this case also the placements of the orders).

client - Stock : The Stock which will replenished.

lt - NumericalDist : The lead time random number distribution to determine the time between placement and receipt of an order. If null the lead time is zero.

showInTrace - boolean : Flag for showing the RestockProcessQT in trace-files. Set it to true if RestockProcessQT should show up in trace. Set it to false if RestockProcessQT should not be shown in trace.

                        TimeSpan t,
                        Stock client,
                        boolean showInTrace)

Constructs a RestockProcessQT which restocks a client Stock after a fixed time period with a fixed quantity of units. The lead time is zero.

Parameters:

owner - Model : The model this RestockProcessQT is associated to

name - java.lang.String : The name of the RestockProcessQT

q - long : The quantity supplied to the Stock with every order.

t - TimeSpan : The time period between the inventory reviews (in this case also the placements of the orders).

client - Stock : The Stock which will replenished.

showInTrace - boolean : Flag for showing the RestockProcessQT in trace-files. Set it to true if RestockProcessQT should show up in trace. Set it to false if RestockProcessQT should not be shown in trace.

Method Detail

getLeadTime

public NumericalDist<?> getLeadTime()

Returns the random number distribution for the lead time (time between placement and receipt of an order).

Returns:

NumericalDist : The random number distribution for the lead time (time between placement and receipt of an order).

getOrderQuantity

public long getOrderQuantity()

Returns the quantity (number of units) to be stored in the Stock.

Returns:

long : The Stock will be replenished with this number of units.

getReviewSpan

public TimeSpan getReviewSpan()

Returns the time span between every replenishment of the Stock.

Returns:

TimeSpan : The time (as a SimTime object) between every replenishment of the Stock.

lifeCycle

public void lifeCycle()
               throws DelayedInterruptException,
                      InterruptException,
                      SuspendExecution

The RestockProcessQT replenishes the associated Stock with the given quantity (Q) every period (T).

Specified by:

lifeCycle in class SimProcess

Throws:

DelayedInterruptException

InterruptException

SuspendExecution

setLeadTime

public void setLeadTime(NumericalDist<java.lang.Double> newLeadTime)

Set the lead time to a new real random number distribution. If set to null the lead time is zero.

Parameters:

newLeadTime - desmoj.dist.RealDist : The new real random number distribution determining the lead time.

setOrderQuantity

public void setOrderQuantity(long newOrderQuantity)

Sets the order quantity to a new value. Zero or negative values will be rejected.

Parameters:

newOrderQuantity - long : Choose a postitive value greater than zero as new order quantity.

setReviewSpan

public void setReviewSpan(TimeSpan newReviewSpan)

Sets the review period to a new value.

Parameters:

newReviewPeriod - desmoj.SimTime : The new value for the review period. null will be rejected.
