摘要：

At present, most of the work has focused on Web services composition from the QoS side, little work being done on investigating how to implement service selection based on transactional and QoS requirements. In complicated network environment, composite services need transactional support for correct and reliable execution. Therefore, How to design a composite service to ensure not only correct and reliable execution but also optimal QoS is a challenging issue. This paper addresses the problem of selecting services by aggregating the transactional and QoS requirements. First, we presented global optimization selection algorithms based on two selection models of composite service with transactional requirements. Then, a heuristic selection algorithm is presented to select an approximately optimal transactional composite service within a reasonable time. Lastly, experiments are conducted to analyze the performance of our proposed algorithms. © 2012 Binary Information Press.
