为了能够更好地满足用户对服务组合的需要,文中首先给出了多层次组合Web服务的筛选模型,并将多层次组合Web服务筛选模型分为五个步骤。在此基础上将Web服务的属性分为功能属性和非功能属性(即QoS属性)。通过划分服务类对功能属性进行描述,并按照服务类以QoS属性的类型进行服务组合。最后给出了多目标方案筛选方法及其实验。
In order to be able to better meet the needs of users for service composition, the article first gives a screening model of multi-level combination of Web services, and multi-level combination of Web service filtering model is divided into five steps. On this basis, the attributes of Web services are divided into functional attributes and non-functional attributes (ie QoS attributes). Describe the functional attributes by classifying the service classes and make service composition according to the service classes with the type of QoS attributes. Finally, the multi-objective scheme screening method and its experiment are given.
