Cyber-Physical Systems (CPS) are known to be highly complex systems which can be applied to a variety of different environments, covering both civil and military application domains. As CPS are typically complex systems, its design process requires strong guarantees that the specified functional and non-functional properties are satisfied on the designed application. Model-Driven Engineering (MDE)...
With the rapid advancement of autonomous driving and vehicular communication technology, intelligent intersection management has shown great promise in improving transportation efficiency. In a typical intelligent intersection, an intersection manager communicates with autonomous vehicles wirelessly and schedules their crossing of the intersection. Previous system designs, however, do not address...
In this paper, we consider a binary parallel composition of FSMs (that are probably partial) and discuss how to check whether this composition is safe or not, i.e. in fact, we check whether there are no deadlocks and livelocks in the composition. We propose a technique for checking this property step-by-step: at the first step we analyze the components separately, at the second step we build the global...
We elaborate on our former work for the safety control of infinite reactive synchronous systems modeled by arithmetic symbolic transition systems. By using abstract interpretation techniques involving disjunctive polyhedral over-approximations, we provide effective symbolic algorithms allowing to solve the deadlock-free safety control problem while overcoming previous limitations regarding the non-convexity...
This paper is focused on understanding techniques used to formally verify behaviour of business processes developed using WS-BPEL standard. The first part of the paper gives an overview of WS-BPEL control-flow constructs. We analyze offered constructs and try to derive control-flow scenarios that can be built out of them. Derived complex control-flow scenarios are further discussed. Possible execution...
