It is because there is a relationship between the Non-functional properties, such that some of the candidate atoms QoS services may have different values in different scenarios, and therefore, during atoms service composition to fully consider the relationship to form the best combination of service processes.
It is precisely because of the association between the non functional attributes of the service that some candidate atomic services may have different QoS values in different scenarios. Therefore, when composing atomic services, we should fully consider these association relationships to form the optimal composition service process<br>
