Abstract

Service oriented systems are becoming a major area in software engineering due to promise of low time and cost of development efforts. However, in order to enable full benefit of service oriented architecture, some technical aspects of service-level agreements, also known as Quality of Service (QoS) are important to be evaluated in formal way. Currently evaluation of web service QoS is done mainly as underlying part of a corresponding composition model and many models consider only limited number of QoS attributes. In this paper we present an approach for evaluation of composite web-services, based on analysis of how they meet their QoS, which is applicable at multiple levels of service composition as well as for wide range of QoS attributes. Our approach is based on probability theory and is illustrated with a case-study.
