The aim of this work is to analyze the Italian emergency system, particularly the Italian radio communication system 118 for the region Campania, and to investigate the effects of the management of different users having different gravity codes for the required services. The real system under consideration can be modelled with a tandem queueing network. The first node describes the calls of users, and can be seen as an exponential queueing system. The second node describes the assistance means communication apparatus with the headquarters of 118 and, in the actual real system, works in such way that it can be modeled as a M/M/c/infinity queue, where c are the couple of frequencies. We propose a radio communication system modelled as a M4/M4/c/infinity queueing system with priority service discipline. For the computation of analytical results, we reduce the number of gravity codes, modeling the second node with a M2/M/c/infinity queueing system with priorities.

Abstract

The aim of this work is to analyze the Italian emergency system, particularly the Italian radio communication system 118 for the region Campania, and to investigate the effects of the management of different users having different gravity codes for the required services. The real system under consideration can be modelled with a tandem queueing network. The first node describes the calls of users, and can be seen as an exponential queueing system. The second node describes the assistance means communication apparatus with the headquarters of 118 and, in the actual real system, works in such way that it can be modeled as a M/M/c/infinity queue, where c are the couple of frequencies. We propose a radio communication system modelled as a M4/M4/c/infinity queueing system with priority service discipline. For the computation of analytical results, we reduce the number of gravity codes, modeling the second node with a M2/M/c/infinity queueing system with priorities.
