摘要:

为解决具有混合服务质量(QoS)和多决策者的服务组合难题,基于多属性群决策理论,提出了混合QoS感知的web服务组合群决策(GDMA_HQoS)算法,该算法支持多决策者和具有混合QoS信息(实数、区间数、三角模糊数、直觉模糊数)的服务组合.给出了新QoS指标描述方法和QoS聚合算法.实验结果表明,该算法能较好地应用在混合QoS和多决策者的服务组合中,同时也具有较高的执行效率.

关键词: web服务, 服务组合, 服务质量, 多决策者

Abstract:

For solving the difficulties of web service composition with hybrid quality of service (QoS) and multiple decision makers, based on multi-attribute group decision making theory, hybrid QoS-aware web service composition (GDMA_HQoS) algorithm was presented. GDMA_HQoS can support multiple decision-makers and hybrid QoS information expressed by real numbers, interval numbers, triangular fuzzy numbers, intuitionistic fuzzy numbers (I). Other contributions included a novel QoS model, an algorithm of aggregating QoS. Experimental results show the proposed algorithm can be better applied in service composition with hybrid QoS and multiple decision makers.

Key words: web service, service composition, quality of service, multiple decision maker
