【摘要】:在滿足功能需求的前提下,Web服務(wù)能否贏得市場(chǎng),主要取決于其服務(wù)質(zhì)量(Quality of Services,QoS)。采用概率模型檢驗(yàn)的方法判斷Web服務(wù)計(jì)算組合流程的服務(wù)質(zhì)量是否滿足系統(tǒng)質(zhì)量需求。依據(jù)用戶訪問(wèn)Web服務(wù)產(chǎn)生的訪問(wèn)日志,采用聚類的方法,構(gòu)建面向用戶群組的Web服務(wù)流程的使用行為QoS模型。采用QoS擴(kuò)展的狀態(tài)圖描述Web服務(wù)流程的QoS需求。然后,利用概率模型驗(yàn)證工具PRISM判斷Web服務(wù)流程的QoS是否滿足系統(tǒng)質(zhì)量需求。驗(yàn)證面向用戶群組的Web服務(wù)流程的使用行為質(zhì)量模型是否滿足系統(tǒng)質(zhì)量需求,為服務(wù)流程結(jié)構(gòu)的調(diào)整提供了依據(jù)。
[Abstract]:On the premise of meeting the functional requirements, whether Web service can win the market depends mainly on its quality of service (Quality of Services,QoS). The probabilistic model checking method is used to judge whether the service quality of the Web service computing composition process meets the system quality requirements. Based on the access logs generated by user access to Web services, a QoS model of user group-oriented usage behavior of Web services process is constructed by using clustering method. The state diagram extended by QoS is used to describe the QoS requirements of the Web service process. Then, the probabilistic model verification tool PRISM is used to determine whether the QoS of the Web service process meets the system quality requirements. This paper verifies whether the user group-oriented Web service process usage behavior quality model meets the system quality requirements and provides a basis for the adjustment of service process structure.
