Tutorial Exercise 1

Exercise Information

Four wagons are parked 300 meters away from a station, we need to send a locomotive there in order to bring those wagons back to the station. The locomotive has a maximum speed of 8 m/s when uncoupled and a maximum speed of 4 m/s when coupled. The path from the station to the wagons is a straight rail. Create a model that represents this problem.

Creating objects

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

• Create one Source Train.
• Create three Rails, then resize Rail2 xvalue to 300. Connect the Source Train to the Rail1 (using the A key) and then connect Rail1 to Rail2 and Rail2 to Rail3 via proximity.
• Create a RailControlPoint and place it on Rail3. The RailControlPoint should change color if it is connected correctly to the Rail. We recommend the creation of the RailControlPoint in a empty space and, after that, you can place it on the Rail.

Your model should be looking like this:

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 and a CreateWagon.
• Create a MoveTrain.
• Create a CoupleWagon.
• Create a MoveTrain.
• Create a Sink.

Your processflow should be looking like this:

To configure your processflow tasks follow the steps:

• On CreateTrain points the SourceTrain reference to your SourceTrain, set the Locomotive Uncoupled to 8 and set the Locomotive Coupled to 4.
• On CreateWagon points the RailControlPoint reference to the RailControlPoint on Rail3 and set wagons quantity to 4.
• On MoveTrain set train reference to token.train and destiny to the RailControlPoint on Rail3.
• On CoupleWagon set train reference to token.train and wagon reference to token.wagon.
• On MoveTrain set train reference to token.train and destiny to Rail1.

With this configuration your model is ready.
