Stochastic model checking is using the verification method of model checking to quantitative verification system model with stochastic behaviours. In recent years, stochastic model checking make a great advancement. In this paper, the high level system model PPN is extended with label, and is used to as the formal model for system with stochastic behaviours; PCTL∗ is selected to as the property specification,...
Model checking has established as an effective method for automatic system analysis and verification. It is making its way into many domains and methodologies. Applying model checking techniques to a new domain (which probably has its own dedicated modeling language) is, however, far from trivial. Translation-based approach works by translating domain specific languages into input languages of a model...
Linearizability is an important correctness criterion for implementations of concurrent objects. Automatic checking of linearizability is challenging because it requires checking that: 1) All executions of concurrent operations are serializable, and 2) the serialized executions are correct with respect to the sequential semantics. In this work, we describe a method to automatically check linearizability...
Modeling and verifying complex real-time systems, involving timing delays, are notoriously difficult problems. Checking the correctness of a system for one particular value for each delay does not give any information for other values. It is hence interesting to reason parametrically, by considering that the delays are parameters (unknown constants) and synthesize a constraint guaranteeing a correct...
In recent years, many Web service composition languages have been proposed. Web service choreography describes collaboration protocols of cooperating Web service participants from a global view. Web service orchestration describes collaboration of the Web services in predefined patterns based on local decision about their interactions with one another at the message/execution level. In this work,...
UML has become the dominant modeling language in software engineering arena. In order to reduce cost induced by design issues, it is crucial to detect model-level errors in the initial phase of software development. In this paper, we focus on the formal verification of dynamic behavior of UML diagrams. We present an approach to automatically verifying models composed of UML state machines. Our approach...
