Towards Integrated Correctness Analysis and Performance Evaluation of Software Systems (Doctoral Forum Paper)

Abstract

In recent times, the involvement of computer systems in our lives has been drastically increasing, as has the need of improving the resilience of these systems, e.g. so they can withstand errors and changes in their environment. Techniques such as testing and simulation are often used to ensure this, but in the case of complex, real-time systems, these techniques can only provide coverage for a limited set of possible system behaviours. Software model checking and stochastic verification are alternative techniques that formally and exhaustively verify whether software meets its functional requirements and establish the performance and dependability properties of software, respectively. The two formal techniques are often used in isolation, yet software must simultaneously ensure a combination of functional and non-functional requirements. The doctoral project described in this paper aims to bring these two areas of software verification together by enabling the joint analysis of functional and non-functional properties of software systems.
