Tutorial Exercise 1.1
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.
Step 1 Creating objects
In order to achieve the solution for the problem, you should create the following objects:
- Create one SourceTrain.
- Create three Rails, then resize Rail2 xvalue to 300. Connect the SourceTrain 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:
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" and a "CreateWagon" activities.
- Create a "MoveTrain" activity.
- Create a "CoupleWagon" activity.
- Create a "MoveTrain" activity.
- Create a Sink.
Your processflow should be looking like this:
To configure your processflow tasks follow the steps:
- On "CreateTrain" activity, point the "Source Train" reference to your SourceTrain, set the "Uncoupled Unloaded" to 8 and set the "Coupled Unloaded" to 4 on the Customize Locomotive Speeds.
- On "CreateWagon" activity, point the "Control Point" reference to the RailControlPoint on Rail3, set wagons quantity to 4 and check "Reverse Create".
- On "MoveTrain" activity, set train reference to "token.train" and destiny to the label "token.wagon".
- On "CoupleWagon" activity, set train reference to "token.train" and wagon reference to "token.wagon".
- On "MoveTrain" activity, set train reference to "token.train" and destiny to Rail1.
With this configuration your model is ready.
