NuSMV is a well-known tool for system verification that permits to verify both CTL and LTL properties. Although the tool is very powerful, it offers a minimal support for the editing and validation (e.g., by simulation) of models and of requirements specified as temporal properties. In this paper, we propose NuSeen, a framework that assists a designer during the modeling and V&V activities when...
The MAPE-K (Monitor-Analyze-Plan-Execute over a shared Knowledge) feedback loop is the most influential reference control model for autonomic and self-adaptive systems. This paper presents a conceptual and methodological framework for formal modeling, validating, and verifying distributed self-adaptive systems. We show how MAPE-K loops for self adaptation can be naturally specified in an abstract...
In case of under specified or not fully predictable systems, models specifying system behaviors are no deterministic. No determinism poses several challenges for the validation and verification activities, including the problem of inconclusive tests in model-based testing with model checker. It is a validation technique that uses model checker counterexamples as test cases. In this paper, we tackle...
