![]() The global interaction behavior in such systems can be specifi ed as a conversation protocol: A fi nite-state machine specifying acceptable sequences of messages exchanged by a group of peers. We focus on analyzing interactions among a set of peers that use message-based communication. The results are extended to address choreographies that employ behavioural rules based on data. A compositional approach to choreography engineering, enabled by the synchronous semantics of Protocol Modelling, is explored and results established concerning sufficient conditions for choreography realizability. In this application Protocol Modelling is used as a medium to describe choreographies for asynchronous multiparty collaborations. TYPESTATUS IOS 9.3.3 SOFTWAREThis is compared with more traditional forms of software contract in the generalization of the notion of contractual obligation as a mechanism for software specification. This proposes the use of protocol models as a medium for expressing formal behavioural contracts. Protocol Modelling is compared with other object modelling techniques in particular by contrasting its compositional style with traditional hierarchical inheritance. This explores the use of Protocol Modelling as a medium for object modelling, and the facility to execute protocol models is described. The second half of the thesis explores three applications of Protocol Modelling: Object Modelling. Comparison is made with other process algebras and an approach to unification of different formulations of the semantics of process composition is proposed. The formal semantics is extended to cover instantiation of objects. A formal denotational semantics for protocol machines is developed and used to establish various properties in particular that composition is closed and preserves type safety. The first half of the thesis focuses on describing and defining the Protocol Modelling technique. Protocol Modelling can be viewed as a hybrid of object orientation, as it supports ideas of data encapsulation and object instantiation and process algebra, as it supports a formally defined idea of process and process composition. 88 17.This thesis develops and explores a technique called Protocol Modelling, a mathematics for the description of orderings.
