Constructor Detail

RestockProcessMT

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

Constructs a RestockProcessMT which restocks a client Stock after a fixed time period up to a maximum inventory level. 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 RestockProcessMT is associated to

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

mil - long : The maximum inventory level the Stock will be filled up to 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 RestockProcessMT in trace-files. Set it to true if RestockProcessMT should show up in trace. Set it to false if RestockProcessMT should not be shown in trace.

RestockProcessMT

public RestockProcessMT(Model owner,
                        java.lang.String name,
                        long mil,
                        TimeSpan t,
                        Stock client,
                        boolean showInTrace)

Constructs a RestockProcessMT which restocks a client Stock after a fixed time period up to a maximum inventory level. The lead time is zero.

Parameters:

owner - Model : The model this RestockProcessMT is associated to

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

mil - long : The maximum inventory level the Stock will be filled up to 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 RestockProcessMT in trace-files. Set it to true if RestockProcessMT should show up in trace. Set it to false if RestockProcessMT should not be shown in trace.

Method Detail

getActualOrderQuantity

public long getActualOrderQuantity()

Returns the quantity (number of units) to be stored in the Stock. Changes every time a new order is placed!

Returns:

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

getLeadTime

public NumericalDist<?> getLeadTime()

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

Returns:

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

getMaxInventoryLevel

public long getMaxInventoryLevel()

Returns the maximum inventory level to which the Stock will be refilled in every cycle.

Returns:

long : The maximum inventory level to which the Stock will be refilled in every cycle.

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 SuspendExecution

The RestockProcessMT replenishes the associated Stock up to the maximum (M) inventory level every period (T).

Specified by:

lifeCycle in class SimProcess

Throws:

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.NumericalDist : The new real random number distribution determining the lead time.

setMaxInventoryLevel

public void setMaxInventoryLevel(long newMaxInventoryLevel)

Sets the maximum inventory level to a new value. Make sure it is greater than zero and less than the capacity of the Stock.

Parameters:

newMaxInventoryLevel - long : The new maximum inventory level. Make sure it is greater than zero and less than the capacity of the Stock.

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.
