30 credits – Signal dependency visualization and status propagation tracking i Sodertalje

Scania is now undergoing a transformation from being a supplier of trucks, buses and engines to a supplier of complete and sustainable transport solutions.

Ingress:
Thesis project at Scania is an excellent way of making contacts for your future working life. Many of our current employees started their career with a thesis project.

Background:
Engine management systems involve complex software architectures with highly configurable modules. Modules dependencies are created through signal that are used to communicate. These signals have a number of properties, including a status indicating the quality of the signal. A degraded signal has impact on the quality of downstream signals. Therefore, understanding the signal dependencies is critical to understanding the overall software behavior.

Target:
Map signal status propagation between modules and degradation actions into an inhibit matrix.

Assignment:
What should be investigated in the thesis project

Use known signal dependencies and create a labelled property graph of signal flow. Add signal status propagation information to the signal flow. Generate an adjacency matrix for with module degradations and signal status.

Education:
Master of Science in Computer Science or Engineering.

Knowledge of programming (C, C++ or Java) and knowledge of graphs.
Number of students: 1-2
Start date: 2019
Estimated time needed: 20 weeks
