MDH research will create safer products through more efficient and effective testing

Nov 15, 2018 | Research/Cooperation

In order to develop safer and cheaper technical products in the transport, manufacturing and telecommunications industry, testing of these products needs to be more efficient and effective. Within the research project XIVT - eXcellence in Variant Testing, researchers at MDH are trying to build the next generation of software testing that is addressing this challenge.

– A big part of today's testing process is done manually, takes time and is costly for companies. We want to develop methods and tools that improves the testing process and makes it more cost effective, which ultimately leads to better, safer and cheaper products, says Eduard Enoiu, project manager for the research project at MDH.

In the next three years, researchers will develop a new way of testing computer systems used in cars, trains, applications in industry and telephones. The computer systems in these products control different functions of the product. For example, in a car there is a braking system, an airbag system, a reversing camera system, etc. These systems need to be able to communicate with one another so that they work together. Each time a car is produced, all the systems in the car are tested to make sure that they can communicate and work together. Since the systems can be combined in thousands of variations, the testing process takes very long time. 

– By developing methods and tools that can detect faults as early as possible in the process and enable testing of many variants to be done automatically, the development process can be more efficient and thus less expensive for the companies. Our aim is to develop a tool that will make the test process 50 percent more efficient compared to today, says Eduard Enoiu.

The research project XIVT is a collaborative project between universities, research institutes, companies within industry and technology suppliers from five different countries. The project has been granted just over SEK 126 million and is financed by the companies involved in the project and research funding, where Vinnova finances the project by just over SEK 16 million. In addition to MDH, four Swedish companies are involved in the project; ABB Process Automation, Addiva, Bombardier Transportation, Percepio and the Rise Research Institutes of Sweden.

– If we can develop methods and tools that detects faults in the system early in the process, by using the variability between different products in a product family, the defects in the final product will decrease. Which means that the products will be better and safer for the user, says Eduard Enoiu.
