基于 QoS 监控的可靠组合服务推荐模型

摘要

企业市场需求与服务信用呈现动态变化，而市场上并未出现一种统一的、可靠的服务体系。针对该问题提出一种基于第三方监督的可靠组合服务推荐模型。首先，引入第三方机制，监督管理服务库的建立，同时监控服务质量的动态变化；而后，建立可靠服务组合平台，进行服务选择、服务组合最优推荐等；以某制造业的加工流程为例，采用基于工作流调度的服务优化组合案例，将采用该模型与不用该模型的成本进行比较，验证所提出的推荐模型的可行性和优越性。%Market demand and service credit are dynamically changing .However, there hasn’t been a unified and reliable serv-ice system.The paper proposes a reliable composite service recommendation model based on third -party supervision .A third-par-ty mechanism is brought in to supervise and administrate the establishment of service library and to monitor the dynamic changes of quality of service;a reliable service composition platform is established to select services , recommend best service composition and perform other functions;taking the process flow of some manufacturing as an example , the paper compares the cost of works using the model and without using the model through a case of service composition optimization based on workflow scheduling , which also verifies the feasibility and superiority of the proposed recommendation model .
