RT Journal Article T1 On the impact of customer balking, impatience and retrials in telecommunication systems A1 Artalejo Rodríguez, Jesús Manuel A1 Pla, V. AB This paper deals with a Markovian multiserver model, where the simultaneous effect of customerbalking, impatience and retrials is evaluated. The study of systems incorporating these features is motivated by the observation of real service systems where these queueing phenomena interact. Simple approximations based on truncation and generalized truncation are provided. These approximations are compared according to different criteria for several selected scenarios. Finally, our results are used to evaluate the optimal ratio between the number of available channels and the number of waiting positions in an application to call center management.
