Generalized Net Representations of the Causal Structure of a Queuing System

Queuing systems are an important part of virtually all service networks. The problem of determining how the Quality of Service (QoS) of a queuing system depends on the qualities of the buffer and the server is not well studied. Two causal decompositions of the services in a queuing system are considered which use the elements of Service Systems Theory. For each of them, a Generalized Net (GN) representation is proposed. The GN models can be used in the study of the QoS composition in overall telecommunication networks.
