摘　　要：根据基于云计算的SaaS(Software as a Service)软件的集成性、可配置性和定制性(简称IIC)所面临的问题.提出一种基于云计算的SaaS组装和质量方法:首先建立一种SaaS寻址方法和组装中断方法,以保证SaaS组装连续性和确定性;并根据寻址和中断情况建一种适合SaaS的相似度计算方法,以满足整个SaaS组装流程的精确性.其次根据SaaS的寻址组装和中断的情况,从Web服务质量、地址数量和分布、可用性、资源共享度、互操作性和ICC等角度建立SaaS组装质量模型,即QoSaaS(Quality of SaaS).第三,在寻址中断支持和QoSaaS驱动下,构建一种SaaS组装算法.最后在Amazon下以一个SaaS销售软件生成为例进行分析,并给出一组数据验证表明该方法的可行性和有效性.SaaS software based on Cloud Computing refers to the following problems： integratability, configurability and customization. Therefore, we propose a composition approach of SaaS based on cloud computing. Firsdy, an approach of services addressing and interrupt are established, both are aimed to guarantee continuity and certainty of SaaS composition, in addition, a similarity calculating method is designed to achieve Sans composition. Secondly, according to SaaS addressing and SaaS composition interrupt and then from the perspectives of QoSaaS （Quality of Software as a Service） , namely, QoS （Quality of Service） , the quantity and the distribution of address, availability of interrupt, expandability, resource sharing, interoperability, and ICC （ integratability, configurability and customization）, quality of SaaS composition are evaluated and their description models are designed so as to strengthen commonality of QoSaaS. Thirdly, SaaS composition approach＇s algorithm based on could computing has been built; Finally, we employ a SaaS online sale software to analyze the approach in the Amazon cloud computing, which could approve that the approach is feasible and availability.
