通过把信任度作为组合服务实现调度和绑定的依据,可以使得组合服务的执行和调度更好地围绕服务的信任度展开,有利于信任度高的成员服务加入到服务组合的过程中来,进而提高组合服务的可信性.把信任引入到服务组合中,研究了信任增强的服务组合的调度问题,建立了调度问题的数学模型,设计了基于蚁群系统的调度算法.通过实验结果分析,表明设计的信任增强的服务组合调度算法具有较好的寻优性能.
Composite service can be scheduled and executed around trust degree of services through introducing trust degree as the accord of service scheduling and execution.Higher trust degree services can join into service composition and the trustiness of composite service can be improved.Trust is introduced into service composition and trust enhanced service composition schedule problem is discussed.The mathematic model of scheduling problem is proposed and the ant colony system based scheduling algorithm is designed.The scheduling algorithm has good performance through analysis of experimental results.
