A simple analysis of a D/GI/1 vacation queue with impatient customers
Assia Boumahdaf
In this paper, we deal with an vacation system with impatient customers. We give a sufficient condition for the existence of a limit distribution of the waiting time and i…
A recursive algorithm for a pipeline maintenance scheduling problem
Assia Boumahdaf, Michel Broniatowski
This paper deals with the problem of preventive maintenance (PM) scheduling of pipelines subject to external corrosion defects. The preventive maintenance strategy involves an insp…
Semiparametric two-component mixture models under L-moments constraints
Diaa Al Mohamad
We propose a structure of a semiparametric two-component mixture model when one component is parametric and the other is defined through L-moments conditions. Estimation of a two-c…
Performance analysis of Markovian queue with impatience and vacation times
Assia Boumahdaf
We consider an queueing system with impatient customers with multiple and single vacations. It is assumed that customers are impatient whenever the state of the server. We…
Modeling and study a general vacation queuing system with impatience customers
Assia Boumahdaf
In this paper we models and studies a general vacation queueing model with impatient customers. We first propose a sufficient condition for the existence of the stationary workload…
Semiparametric two-component mixture models under linear constraints
Diaa Al Mohamad, Assia Boumahdaf
We propose a structure of a semiparametric two-component mixture model when one component is parametric and the other is defined through linear constraints on its distribution func…
