| 2 | At the end of this summer term a railway controller modelled in SCCharts should exist that is able to //control// the model railway installation. What exactly //control// means is up to you! | ||
| 3 | |||
| 4 | Define your project goals! Therefore... | ||
| 5 | |||
| 6 | * Define the desired capabilities of your controller. | ||
| 7 | * Devide your project in several subprojects. Organize the whole team in subteams and determine who is responsible for what. | ||
| 8 | * Define interfaces between the subteams and/or components the subteams are responsible of. | ||
| 9 | * Create a detailed roadmap with milestones for each subproject. | ||
| 10 | |||
| 11 | You are going to present your plan in a short presentation (latex beamer preferred) in the following week, 13.05. 12:30. The presentation should last 30 min. | ||
| 12 | |||
| 13 | Remember, you are going to present your controller at the end of the summer term! Getting this task done right is a very important step to succeed with your controller and this project! | ||

| 18 | **The following goals were defined:** | ||
| 19 | |||
| 20 | * At least 5 trains can drive on the track at the same time | ||
| 21 | * A "cleanup" function for trains should drive all trains to their original position | ||
| 22 | * Our test scenarios should work (see Test-Scenarios) | ||
| 23 | * The trains slow down before braking | ||
| 24 | * All signals are working correctly | ||
| 25 | * Gates should close, when a train is coming, and open again afterwards | ||
| 26 | |||
| 27 | **Additionally the following optional goals were defined:** | ||
| 28 | |||
| 29 | * Deadlock avoidance: Trains should never run into a deadlock | ||
| 30 | * Cleanup function: All Trains which are still on the track travel to their next destination and afterwards they take the shortest way home | ||
| 31 | * Trains should drive slowly at the points | ||
