We present an approach to the specification of concurrent systems, by means of a deductive database management system. The approach is based on the synthesis of logic formulas: starting from a temporal logic formula, that represents the requirements of a system, a general model for such formula, is derived. From this model, all the concurrent systems satisfying the formula can be generated. A graphical...
We present a logical framework that is able to deal with variability in product family descriptions. The temporal logic MHML is based on the classical Hennessy–Milner logic with Until and we interpret it over Modal Transition Systems (MTSs). MTSs extend the classical notion of Labelled Transition Systems by distinguishing possible (may) and required (must) transitions: these two types of transitions...
We propose a model-checking tool for on-the-fly verification of properties expressed in a branching-time temporal logic based on a deontic interpretation of classical modal and temporal operators over modal transition systems. We apply this tool to the analysis of variability in behavioural descriptions of families of services.
We illustrate how to manage variability in a single logical framework consisting of a Modal Transition System (MTS) and an associated set of formulae expressed in the branching-time temporal logic MHML interpreted in a deontic way over such MTSs. We discuss the commonalities and differences with the framework of Classen et al. based on Featured Transition Systems and Linear-time Temporal Logic.
This paper describes a research activity carried on in the frame of a collaboration among ISTI-CNR, leader of the 'Representation and Communication of Data and Metadata' Workpackage in the European Project MUSCLE-NoE ('Multimedia Understanding through Semantics, Computation and Learning Network of Excellence') and the Dept. of Electronics, A.I. & Telecommunications of the Polytechnic University...
