Abstract. CSP is a well-established formalism for modelling and verification of concurrent reactive systems based on refinement. Consolidated denotational models and an effective t...
Probabilistic I/O automata (PIOA) constitute a model for distributed or concurrent systems that incorporates a notion of probabilistic choice. The PIOA model provides a notion of ...
Based on the FOCUS theory of distributed systems (see [Broy, Stølen 01]) that are composed of interacting components we introduce a formal model of services and layered architectu...
