Subject: Computer Science
Level: Advanced
Description: Volvo Construction Equipment:
Volvo Construction Equipment, a business area within the Volvo
Group, is one of the world’s leading manufacturers of construction
equipment such as wheel loaders, excavators, articulated haulers,
road development equipment and compact equipment. Production
facilities are located in Europe, Asia, North America and Latin
America. Please read more about us at our homepage (

Position Description:
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
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.

Description of thesis work:
The target of the thesis is to identify and evaluate appropriate ways of modeling of product lines for safety-critical products at Volvo Construction Equipment.

Fields to be looked at:
· Analyzing the needs and requirements with Product Lines at
Volvo Construction Equipment
· Identification of modeling techniques for different levels of
product lines (UML, Feature Tree,…)
· Evaluation of appropriate tools
· Developing evaluation criteria for modeling product lines at
Volvo Construction Equipment
· Comparison between different techniques
· Development of concept for Product lines for developing safety critical products
