Title: Development of Concepts for Hazard Analysis and Traceability in Product Lines
Subject: Computer Science
Level: Advanced
Description: Job Description
We are looking for a student (m/f) for a Master Thesis within the Functional Safety group at the E/E Architecture Department at Volvo Construction Equipment in Eskilstuna Sweden.

Each new generation of cars or construction machinery that is rolled out onto the market is characterized by an increasing amount of functionality being realized by software. Software is the key-enabler for new technologies and hence the main innovation driver in the automotive domain. Both the number of Electronic Control Units (ECU) and the complexity of the applied interacting software functionality in the Electrical/Electronic (E/E) Systems are increasing. Being cost-conscious as well, due to strict time-to-market requirements, the automotive industry has been more and more looking at component-based development and product line engineering.
The highly dynamic operational environment of these vehicles, where many different types of users are involved, causes even small failures in their E/E systems to probably result in accidents with fatal consequences.
In order to avoid those failures, functional safety standards like ISO 15998, IEC 61508 and ISO 26262 have been developed and introduced in different domains.

Within the past years Volvo Construction Equipment and the Functional Safety Group have been developing applicable methods and processes for complying with the different relevant functional safety standards.
Managing functional safety in the context of product lines is challenging and currently one of the focuses of the Functional Safety Group.

Hazard Analysis techniques are well established both in standards and in industry. In this thesis we are investigating how hazard analysis concepts can be applied in a product line context. Several approaches have been proposed in literature, the most prominent one is of Robyn Lutz [4][5][6]. This needs to be set into the context of ISO 26262 [3] and the procedures at Volvo Construction Equipment.

Tasks
The target of the thesis is to analyze and evaluate different ways of Hazard Analysis concepts and understand how industry is using these concepts.

Fields to be looked at:
• Analyzing the needs and requirements at Volvo Construction Equipment
• Identification of different hazard analysis techniques
• Understanding the context of product lines
• Developing a concept using one or several hazard analysis concepts in the context of product lines.
• Evaluating the concepts in a use case
• Investigate possible extensions to meet the needs
