Tutorial Exercise 3.1

Exercise Information

A train needs to fill up at a fuel station. The train can hold a maximum of 150L of fuel, it is currently holding 10L and using 5L/Km and the fuel station is full with 100L. After that, the train needs to couple a wagon, go to a crane that will load a flow item, which is in a 7x4 queue and is 4x3 in size, onto the train and travel to another crane and finally unload the flow item into a 7x4 queue.

Note: Place 1 unit per flow item at the fuel station.

Step 1 Creating objects

In order to achieve the solution for the problem, you should create the following objects:

Create 7 Rails.
Create a RailControlPoint and put on the middle of Rail1.
Create a Fuel Station and connect (using S key) to the RailControlPoint on Rail1.
On fuel station, Max and Start Weight to 100. Unit per item: 1.
Create a SourceTrain.
Connect the SourceTrain (using A key) to Rail2.
Create a RailControlPoint and put on middle of Rail3.
Create a RailControlPoint and put on middle of Rail4.
Create a RailCrane.
Create a Queue, changing the xsize to 7 and ysize to 4.
On Queue, set the "On Entry" trigger with Visual > Set Location, Rotation or Size. The values are: For "Set" enter Size, "Object" enter Item, "X Size" enter 4, "Y Size" enter 2 and "Z Size" enter 1.
Create a RailCrane.
Create a Queue 7x4.
Create a RailControlPoint and put on middle of Rail5.
Create a RailControlPoint and put on middle of Rail6.
RailSystem: Check the option "Fuel Usage".

Step 2 Processflow Configuration

In order to achieve the solution for the problem, you should create the following processflow tasks:

Create a Schedule Source.
Create a "CreateTrain" activity.
Create a "CreateWagon" activity.
Create a "Create Object" activity.
Create a "MoveTrain" activity.
Create a "FuelTrain" activity.
Create a "MoveTrain" activity.
Create a "CoupleWagon" activity.
Create a "MoveTrain" activity.
Create a "CraneLoad" activity.
Create a "MoveTrain" activity.
Create a "CraneUnload" activity.
Create a "MoveTrain" activity.
Create a "DestroyTrain" activity.
Create a Sink.

Your processflow should be looking like this:

Exercise4PF

To configure your processflow tasks follow the steps:

Create a Schedule Source.
On "CreateTrain" activity, point the "SourceTrain" reference to your Source Train object. Set "Max Fuel" and "Current Fuel" to 150 and the "Fuel Usage" to 5.
On "CreateWagon" activity, point the "Control Point" reference to the RailControlPoint on Rail2 and set wagons quantity to 1.
On "Create Object" activity, check "Create In" and reference to the Queue1.
On "MoveTrain" activity, set train reference to "token.train" and destiny to the RailControlPoint on Rail1.
On "FuelTrain" activity, point the "Control Point" reference to the RailControlPoint on Rail1.
On the second "MoveTrain" activity, set train reference to "token.train" and destiny to the RailControlPoint on Rail3.
On "CoupleWagon" activity, set train reference to "token.train" and wagon reference to "token.wagon".
On the third "MoveTrain" activity, set train reference to "token.train" and destiny to the RailControlPoint on Rail4.
On "CraneLoad" activity, set "Crane" reference to RailCrane1.
On the fourth "MoveTrain" activity, set train reference to "token.train" and destiny to the RailControlPoint on Rail6.
On "CraneUnload" activity, set "Crane" reference to RailCrane2 and "Destination" reference to Queue2.
On the fifth "MoveTrain" activity, set train reference to "token.train" and destiny to Rail1.
On "DestroyTrain" activity, set train reference to "token.train" and "Sink" reference to the Sink next to Rail7.

With this configuration your model is ready.
