We built an EPICS-based radiation therapy machine control program and are using it to treat patients at our hospital. To help ensure safety, the control program uses a restricted subset of EPICS constructs and programming techniques, and we developed several new automated formal verification tools for this subset. To check our control program, we built a Symbolic Interpeter that finds errors in...

Runtime assertion checking provides a powerful, highly automatizable technique to detect violations of specified program properties. This paper provides a lesson on runtime assertion checking with Frama-C, a publicly available toolset for analysis of C programs. We illustrate how a C program can be specified in executable specification language e-acsl and how this specification can be automatic...

Answer Set Programming (ASP) is a successful method for solving range of real-world applications. Despite the availability fast ASP solvers, computing answer sets demands very large computational power, since problem tackled in second level polynomial hierarchy. A speed-up set computation may be attained, if program can split into two disjoint parts, bottom and top. Thus, part evaluated indepen...

This tutorial deals with runtime enforcement and advocates its use as an extension of runtime verification. While research efforts in runtime verification have been mainly concerned with detection of misbehaviors and acknowledgement of desired behaviors, runtime enforcement aims mainly to circumvent misbehaviors of systems and to guarantee desired behaviors. First, we propose a comparison betwe...

Many advanced business applications, collaborations, and virtual organizations are based on distributed business process management. As, in such scenarios, competition, fluctuation and dynamism increase continuously, the distribution and execution of individual process instances should become as flexible as possible in order to allow for an ad-hoc adaptation to changing conditions at runtime. H...
