On the potential advantages of exploiting behavioural information for contract-based service discovery and composition

Antonio Brogi
2011 The Journal of Logic and Algebraic Programming  
On such ground, we also discuss the potential suitability of some well-known modelling approaches to become the de facto standard to represent service behaviour in contracts, also in view of contextual  ...  In this paper we discuss the potentially huge advantages of exploiting behavioural information for service discovery and composition, and relate them to the cost of generating such information and to the  ...  The importance of Quality of Service (QoS) properties has also been recognised since the very birth of Web services (e.g., see [21, 42] ).  ...

Run-time Composition and Adaptation of Mismatching Behavioural Transactions

Javier Camara, Gwen Salaun, Carlos Canal
2007 Fifth IEEE International Conference on Software Engineering and Formal Methods (SEFM 2007)  
Reuse of software entities such as components or Web services raise composition issues since, most of the time, they present mismatches in their interfaces.  ...  These mismatches may appear at different interoperability levels: signature, behaviour, quality of service and semantics.  ...  They are also grateful to the anonymous referees who helped to improve the contents and quality of this article.  ...

Compositional schedulability analysis of real-time actor-based systems

Mohammad Mahdi Jaghoori, Frank de Boer, Delphine Longuet, Tom Chothia, Marjan Sirjani
2016 Acta Informatica  
To check schedulability, we introduce a compositional automata-theoretic approach, based on maximal use of model checking combined with testing.  ...  We show that the analyses are decidable and automate the process using the Uppaal model checker.  ...  At the detailed level, an actor consists of its methods, scheduler and queue. This specification is given in timed automata [7] in order to support automated analysis techniques.  ...
