Generalized aggregate Quality of Service computation for composite services
Yang, Yong, Dumas, Marlon, García-Bañuelos, Luciano, Polyvyanyy, Artem, & Zhang, Liang (2012) Generalized aggregate Quality of Service computation for composite services. Journal of Systems and Software, 85(8), pp. 1818-1830.
This article addresses the problem of estimating the Quality of Service (QoS) of a composite service given the QoS of the services participating in the composition. Previous solutions to this problem impose restrictions on the topology of the orchestration models, limiting their applicability to well-structured orchestration models for example. This article lifts these restrictions by proposing a method for aggregate QoS computation that deals with more general types of unstructured orchestration models. The applicability and scalability of the proposed method are validated using a collection of models from industrial practice.
