Horizontal Web Service Composition using Service Supervision

服务计算技术使我们能够通过将各种服务分配给相同的业务逻辑来配置组合服务的属性。然而，当没有足够的服务可用时，任何服务组合都不能满足给定的需求。为此，我们提出了一个实现服务选择和运行时自适应的综合流程。作为约束满足问题（CSP）的扩展，提出了一种识别服务选择所需服务的有效算法。

Services computing technologies enable us to configure properties of a composite service by assigning various services to the same business logic. When enough services are not available, however, any combination of services cannot satisfy given requirements. Therefore we proposed a comprehensive process which realizes service selection and runtime adaptation. We also showed an efficient algorithm which identifies services to be required by the service selection as an extension of CSP (Constraint Satisfaction Problem).
