Matteucci I., Santini F. Decomposing Global Quantitative Properties into Local Ones. In: 11th International Workshop, DPM 2016 and 5th International Workshop, QASA 2016 (Heraklion, Crete, 26-09 2016). Proceedings, pp. 34 - 50. (Lecture Notes in Computer Science, vol. 9963). Springer, 2016.
In this paper we address the problem of identifying what local properties the sub-components of a system have to satisfy in order to guarantee a (security) property on the behaviour of the whole system.We associate each action with a value. Hence, we end up with quantitative properties on them, which are specified through a modal logic equipped with a parametric algebraic structure (i.e., a c-semiring). The aim is to have a value related to the satisfaction of a formula. Startingfrom the behaviour of a general distributed system (or context ), we propose a formal approach to decompose a global quantitative property intothe local quantitative properties to be satisfied by its sub-contexts.
