考虑原子服务排列顺序的QoS感知Web组合服务选择
QoS-aware composite service selection considering the logic position of atomic services
摘要
Abstract
Seeing that it is difficult to select a composite service with the lowest actual executing price using the existing methods for QoS-aware composite service selection, this paper proposes a new selection method that considers the logic position of atomic services based on the analysis of the influence of atomic services' logic position on the QoS of composite services. The method regards the composite service as a series of atomic services, and in view of the reliability of each atomic service, regards the price averaged for one time of successful execution of a composite as its actual executing price, and then, selects the atomic services with the aim of minimizing the composite service executing price. The simulation result shows that the proposed method is superior to other methods in executing time and executing price.关键词
