A composite service selection algorithm based on structural model

Most research on the problem of execution path selection and component service selection is based on DAG model and few based on structural model. The problem of execution path selection and component service selection is discussed based on structural model of composite service and graph presentation of structural model is established. Using ant colony system as optimizing tool, the problem of execution path selection and component service selection is translated to a hierarchy optimizing problem, and the optimizing algorithm is designed. The optimizing algorithm has good performance through analysis of experimental results.
