不要急，我来帮帮你，但是有可能不是很准确，因为我的能力也有限，仅做参考吧？This paper provides the dynamic web combined method supporting service quality restraint based on service chain, which selects all involved service as alternative service collection by data stream analysis according to the real time requirements provided by users, taking reversal structure service chain based on above to meet users' meets after combination. In the process of combination, supports of service quality have been considered, invocation dependence of service in usage recorded,the used service and topological structure of combination will be output after running, so the dynamic combination of web service with service quality restraint is realized. This method can make sure the feasible and optimal solution be found, and also can handle with the combination structure of branch ,polymerization and recycle very well. Simulation and model test verify the method mentioned in this paper.
