• RECENT DEVELOPMENTS IN QUEUEING MODELS UNDER N-POLICY: A SHORT SURVEY

Abstract

Queueing system under N-Policy have been studied extensively since the late 1963’s. A considerable number of works in this area were completed in the early 90’s. As an extension for the classical queueing system, the N-policy (ie., a server is turned on when the number of customers in the queue size reaches a certain number N and turned him off when the system is empty) makes the model more applicable in a variety of system including optimal management policy, computer processing, manufacturing and transportation system. Motivated by these applications more studies on queueing models under N-Policy have been done during the late 90’s and 2000’s. This paper intends to provide a brief summary of the most recent research works on queueing models under N-Policy in the past 15 years.
