- Abstract:
-
With the increased scale and complexity of real-time concurrent software systems, ensuringtheir correctness and reliability has become a matter of urgency. Current model-checking technology uses an automated demonstration algorithm to judgesystem properties, which must include the traversal in the system model and graph-based analysis techniques as well asextensive numerical computations. In this paper, we consider the timed concurrency model as an extension of the concurrent game model (CGS) and addprobability and time properties to propose a new probabilistic timed concurrent game structure (PTCGS). We also propose a new logic language called probabilistic timed strategy logic (PTSL), which uses strategy as the object in the first-order logic to specify the nonzero-sum attributes in a simple and natural way. Lastly, we give an example usingthe ZeroConf protocol to demonstrate the correctness of the PTSL model checking method.
