In this article, we propose a comprehensive approach for Quality of Service (QoS) calculation in service composition. Differing from the existing work on QoS aggregations that represent as single values, discrete values with frequencies, or standard statistical distributions, proposed has capability to handle any type probability distribution. A set formulae and algorithms are developed calculate composite according four identified basic patterns sequential, parallel, conditional, loop. We demonstrate method is much more efficient than simulation methods. It high scalability builds solid foundation real-time analysis prediction Experiment results provided show effectiveness efficiency method.
