public abstract class Transporter
extends SimProcess

A Transporter represents any kind of vehicle or conveyor belt which carries goods (products) around in a manufacturing system. It has a certain capacity (maximum number of goods which can be carried around at once) and a minimum load (minimum number of goods which will be carried). Transporter is derived from SimProcess. Its lifeCycle() must be implemented by the user in order to specify the behavior of the Transporter.

Constructor Detail

Transporter

public Transporter(Model owner,
                   java.lang.String name,
                   int minLoad,
                   int capac,
                   boolean showInTrace)

Constructs a Transporter which will carry around goods in a manufacturing system. Implement its lifeCycle() method to specify its behavior. A Transporter has a capacity (maximum number of goods which can be transported) and a mimimum load ( a minimum number of goods it will carry). Both must not be zero or negative. Their default value is one.

Parameters:

owner - desmoj.Model : The model this Transporter is associated to.

name - java.lang.String : The name of this Transporter.

minLoad - int : The minimum number of goods this Transporter will carry around.

capac - int : The maximum number of goods this Transporter can carry around.

showInTrace - boolean : Flag, if this Transporter should produce a trace output or not.

Transporter

public Transporter(Model owner,
                   java.lang.String name,
                   int capac,
                   boolean showInTrace)

Constructs a Transporter which will carry around goods in a manufacturing system. Implement its lifeCycle() method to specify its behavior. A Transporter has a capacity (maximum number of goods which can be transported) and a mimimum load (a minimum number of goods it will carry). Use this constructor to construct a Transporter with a specified capacity and a minimum load of one.

Parameters:

owner - desmoj.Model : The model this Transporter is associated to.

name - java.lang.String : The name of this Transporter.

capac - int : The maximum number of goods this Transporter can carry around.

showInTrace - boolean : Flag, if this Transporter should produce a trace output or not.

Method Detail

getCapacity

public int getCapacity()

Returns the capacity of this Transporter. That is the maximum number of goods it can carry around the manufacturing system.

Returns:

int : The capacity of this Transporter.

getMinLoad

public int getMinLoad()

Returns the minimum load of this Transporter. That is the minimum number of goods which must be loaded on this Transporter before it starts carrying them to their destination.

Returns:

int : The minimum load of this Transporter

lifeCycle

public abstract void lifeCycle()
                        throws SuspendExecution

Override this method in a subclass of Transporter to implement the Transporters specific behaviour. It will at least contain something to let this Transporter wait in a TransportJunction for goods to carry around, like
TransportJunctionXY.cooperate(transportation);
This method starts after a Transporter has been created and activated by the scheduler. It describes the behavior of this special Transporter when he is acting alone. All action taking place when this Transporter (as a master) acts together with other SimProcess es (as slaves) in some process cooperation is described in that special cooperation method of the class Transportation.

Specified by:

lifeCycle in class SimProcess

Throws:

SuspendExecution

setCapacity

public void setCapacity(int newCapacity)

Sets the capacity of this Transporter to a new value. The new value must not be zero or negative.

Parameters:

newCapacity - int : The new capacity of this Transporter.

setMinLoad

public void setMinLoad(int newMinLoad)

Sets the minimum load of this Transporter to a new value. The new value must not be negative.

Parameters:

newMinLoad - int : The new minimum load of this Transporter.
