摘要: 针对当前基于QoS的Web服务组合研究仅限于QoS生命周期的某一环节,提出了一个支持QoS生命周期管理的Web服务框架,基于该框架研究了服务组合在线优化的方法,提出了自动修正判断矩阵的层次分析法来实现基于QoS的在线局部优化策略。该方法针对因各种原因用户只能提供各QoS属性之间的相对重要性,而不能提供全局的QoS需求的应用场景,提供了一种在线局部优化解决方案。

Abstract: Currently,most researches only focus on some phase of QoS lifecycle management,this paper proposes a frame that supports the management of whole QoS lifecycle.Based on this frame,an AHP approach with automatically modifying judgement matrix is proposed to implement online strategy of local QoS optimization.Traditionally,consumer can only provide relative importance of QoS properties,but cannot describe the global QoS requirement.Aiming at this scenario,this approach provides an online local optimization solution.
