Corrected phase-type approximations of heavy-tailed queueing models in a Markovian environment
Eleni Vatamidou, Ivo J. B. F. Adan, Maria Vlasiou +1
We develop accurate approximations of the delay distribution of the MArP/G/1 queue that cap- ture the exact tail behavior and provide bounded relative errors. Motivated by statisti…
Corrected phase-type approximations of heavy-tailed queueing models in a Markovian environment
Eleni Vatamidou, Ivo J. B. F. Adan, Maria Vlasiou +1
Significant correlations between arrivals of load-generating events make the numerical evaluation of the workload of a system a challenging problem. In this paper, we construct hig…
Corrected phase-type approximations of heavy-tailed risk models using perturbation analysis
Eleni Vatamidou, Ivo J. B. F. Adan, Maria Vlasiou +1
Numerical evaluation of performance measures in heavy-tailed risk models is an important and challenging problem. In this paper, we construct very accurate approximations of such p…
A Lindley-type equation arising from a carousel problem
Maria Vlasiou, Ivo J. B. F. Adan, Jaap Wessels
In this paper we consider a system with two carousels operated by one picker. The items to be picked are randomly located on the carousels and the pick times follow a phase-type di…
