A Single Server Retrial Queue with Different Types of Server Interruptions
Tewfik Kernane
We consider a single server retrial queue with the server subject to interruptions and classical retrial policy for the access from the orbit to the server. We analyze the equilibr…
Fixed Point Iteration for Estimating The Parameters of Extreme Value Distributions
Tewfik Kernane, Zohrh A. Raizah
Maximum likelihood estimations for the parameters of extreme value distributions are discussed in this paper using fixed point iteration. The commonly used numerical approach for a…
A Unified Approach of Parameter Estimation
Ahmed Guellil, Tewfik Kernane
We introduce a new distance and we use it to parameter estimation purposes. We observe how it operates and we use in its place the usual methods of estimation which we call the met…
Conditions for stability and instability of retrial queueing systems with general retrial times
Tewfik Kernane
We study the stability of single server retrial queues under general distribution for retrial times and stationary ergodic service times, for three main retrial policies studied in…
A New Approach of Point Estimation from Truncated or Grouped and Censored Data
Ahmed Guellil, Tewfik Kernane
We propose a new approach for estimating the parameters of a probability distribution. It consists on combining two new methods of estimation. The first is based on the definition…
