Modelos de Bloqueio para Ambientes Competitivos

The classical Erlang models are related to a situation in which a single operator supplies channels to a user population. Accordingly, they assume a monopolistic business model. In this work, we extend the Erlang-B model to a situation in which channels are supplied by two operators in a competitive business environment. The analysis is based on Game Theory and shows that, in the presence of cost asymmetries, the operators game tends to restore a competitive monopoly, although at a more favorable service level (blocking probability) than in a statutory monopoly.
