摘　　要：为满足对云服务组合的个性化需求,对一类含有物流服务的服务组合QoS评价方法进行研究,建立了含有物流服务的云服务描述模型,在此基础上计算云服务的相关QoS指标.为对指标值进行科学的综合评价,提出了一种基于历史数据的主客观结合QoS指标权值设定方法.最后用一个汽车零件加工过程的实例进行验证,验证结果表明提出的含物流服务的服务组合QoS评价方法可行及有效.To meet the individual needs of cloud services composition, the QoS evaluation method of the service composition considering logistics services was researched, and a cloud service description model was constructed. On this basis, related QoS metrics of cloud service were calculated. To make a comprehensive evaluation of the index value, a historical data based subjective and objective QoS metrics weights setting method was given. Finally, an auto parts process instance was used to verify, and the case study illustrates the feasibility and effectiveness of the method to evaluate QoS of service composition containing logistics services.
