Hybrid reliability model to enhance the efficiency of composite web services

In this paper, a service-oriented reliability model that calculates the reliability of composite web services is designed. This model is based on the real-time reliabilities of the atomic web services of the composition. This manuscript contradicts the fact that the reliability of system is based on the exponential function of error arrival rate. The Reliability rate of composite web services is inversely proportional to the workload of the servers. After obtaining the server workload, we dispatch the services into Idle and Active State using doubly stochastic model. This model assumes a Single Composite Service and the atomicity of the services are dispatched in both serial and parallel configurations. A Broker Architecture based on Bounded set technique is designed to deduce the error in the active state by calculating accessibility, availability and error rate. These factors are represented in terms of MTTE, MTBF, MEAR which in turn used to dispatch the services into the server which provides high reliability.
