“…The use of interrelated viewpoints is recommended for ODS by the ITU [26] and work on combining viewpoints in this setting has been based on e.g. Object-Z [6,19] and timed automata [5]. Two major differences between these approaches and ours are, first, that they are state-based whereas we prefer to model objects at an early stage by observations and, second, they are synchronous whereas we find asynchronous communication natural for distributed systems.…”

An object-oriented approach to program specification and verification was developed by Ole-Johan Dahl with the long-term Abel project. Essential here was the idea of reasoning about an object in terms of its observable behavior, where the specification of an object's present behavior is given by means of its past interactions with the environment. In this paper, we review some of the ideas behind this approach and show how they can be fruitfully extended for reasoning about black-box components in open object-oriented distributed systems.

“…A rich approach based on the classical foundations of specification and refinement has been developed by Derrick, Boiten, Bowman, e.a., known as the Kent group [6], [28]. In their approach, viewpoint specifications are linked by relations, called correspondences, and consistency is checked for the connected identifiers.…”

Abstract-Nowadays, due to the explosive spreading of networked and highly distributed systems, mastering system complexity becomes a critical issue. Two development and verification paradigms have become more popular: viewpoints and randomisation. The viewpoints offer large freedom and introduce concurrency and compositionality in the development process. Randomisation is now a traditional method for reducing complexity (comparing with deterministic models) and it offers finer analytical analysis tools (quantification over nondeterminism, multi-valued logics, etc). In this paper, we propose a combination of these two paradigms introducing a viewpoint methodology for systems with stochastic behaviours.
