Understanding customer retrials in call centers: preferences for service quality and service speed

open access: yes, 2021
Problem definition: Customers are likely to initiate retrial calls when their previous contact with a call center fails to deliver a satisfactory resolution.

Waiting Time Distribution and Some Characteristics in Finite Queueing Systems with Retrials [PDF]

open access: yesThe Egyptian Statistical Journal, 2001
A retrial queueing system consists of a primary service facility of finite capacity and an orbit. Customers arrive from outside the system according to Poisson process, or from the orbit according to a rate that depends upon the number of customers in ...

Resource Orchestration Strategies With Retrials for Latency-Sensitive Network Slicing Over Distributed Telco Clouds

open access: yesIEEE Access, 2021
The new radio technologies (i.e. 5G and beyond) will allow a new generation of innovative services operated by vertical industries (e.g. robotic cloud, autonomous vehicles, etc.) with more stringent QoS requirements, especially in terms of end-to-end ...

Modified Erlang Loss System for Cognitive Wireless Networks

open access: yesMathematics, 2022
This paper considers a modified Erlang loss system for cognitive wireless networks and related applications. A primary user has pre-emptive priority over secondary users, and the primary customer is lost if upon arrival all the channels are used by other

Retrial BMAP/PH/N Queueing System with a Threshold-Dependent Inter-Retrial Time Distribution

open access: yesMathematics, 2022
In this paper, we study a multi-server queueing system with retrials and an infinite orbit. The arrival of primary customers is described by a batch Markovian arrival process (BMAP), and the service times have a phase-type (PH) distribution.

the procédure of retrial

open access: gold, 2015
La cohabitation entre la révision en matière pénale et l’autorité de la chose jugée constitue la pierre angulaire de notre réflexion. En effet, en autorisant la remise en cause d’une décision définitive, la révision déroge au principe cardinal de l’immutabilité des décisions de justice une fois celles-ci revêtues de l’autorité de la chose jugée.

Heavy traffic analysis of a polling model with retrials and glue periods [PDF]

open access: yes, 2017
We present a heavy traffic analysis of a single-server polling model, with the special features of retrials and glue periods. The combination of these features in a polling model typically occurs in certain optical networking models, and in models where ...
