Type: conference-paper
Abstract: Using probabilities in the formal-methods-based development of safety-critical software has quickened\ninterests in academia and industry. We address this area by our model-driven engineering\nmethod for reactive systems SPACE and its tool-set Reactive Blocks that provide an extension to\nsupport the modeling and verification of real-time behaviors. The approach facilitates the composition\nof system models from reusable building blocks as well as the verification of functional and\nreal-time properties and the automatic generation of Java code.\nIn this paper, we describe the extension of the tool-set to enable the modeling and verification\nof probabilistic real-time system behavior with the focus on spatial properties that ensure system\nsafety. In particular, we incorporate descriptions of probabilistic behavior into our Reactive Blocks\nmodels and integrate the model checker PRISM which allows to verify that a real-time system satisfies\ncertain safety properties with a given probability. Moreover, we consider the spatial implication\nof probabilistic system specifications by integrating the spatial verification tool BeSpaceD and give\nan automatic approach to translate system specifications to the input languages of PRISM and Be-\nSpaceD. The approach is highlighted by an example.
