基于模板的服务选择方法
Method of Web Service Selection Based on Template
摘要
Abstract
Services arc protean in Web environment. There may be several services which provide the same function,and those services have different quality of service. Selecting a service instance for each service node of the template with optimal QoS under the condition of satisfying the global QoS constraints,is the key of service composition. Based on composition template,proposed a model to solve the problem of QoS global optimal in the process of template selection and service selection. Build the model of template QoS to maximize the probability to select optimal QoS template. The problem of service selection with QoS global optimal is transformed into a multi-objective services composition with QoS constraints. Produce a set of optimal services composition process with constraint principle by means of optimizing various QoS parameters simultaneously. Experimental results show the feasibility and efficiency of this method.关键词
