The automatic generation of witness and counterexample is considered as the key advantage of model checking. It provides a useful source of diagnostic information and a basis for automated test generation. However, some of the witness traces may be unreasonably long and highly redundant that makes achieving test purpose even for small systems inefficient. This paper presents a technique for automated...
Probabilistic real-time systems have a difficult controlling management, because of their random behaviors and quantitative operations. So, the procedure of system behavior will changed any time. Adding a probable factor can effect on some systematic problems such as fairness, deadlock and starvation in a probabilistic real-time system. In this paper, we study on a new probable decision making approach...
The analysis of probabilistic schedulability explores all possible combinations of the probabilities of task attributes, which can easily lead to exponential computation time [24]. In this paper, we present a flexible schedulability analysis framework for periodic and sporadic tasks having probabilistic attributes where the computation time scales linearly in the size of analyzed systems. The framework...
Analysis and verification of safety critical systems is inevitable to assure functional and temporal correctness. For checking temporal system behaviour, real-time scheduling analysis has been proved to be an efficient method. As an analytical method, real-time scheduling relies on rather simple task network models mostly ignoring functional behaviour in order to remain computable and efficient. Functional...
