Covert queueing problem with a Markovian statistic [PDF]
2021 IEEE Information Theory Workshop (ITW), 2021 Based on the covert communication framework, we consider a covert queueing problem that has a Markovian statistic. Willie jobs arrive according to a Poisson process and require service from server Bob. Bob does not have a queue for jobs to wait and hence when the server is busy, arriving Willie jobs are lost. Willie and Bob enter a contract under which

The Queueing Model MAP|PH|1|N with Feedback Operating in a Markovian Random Environment
Austrian Journal of Statistics, 2016 Queueing systems with feedback are well suited for the description of message transmission and manufacturing processes where a repeated service is required. In the present paper we investigate a rather general single server queue with a Markovian Arrival

Optimizing Cardiac Inpatient Flow and Resource Allocation in Low-Resource Settings Using Queuing Theory: Insights From a Tertiary Hospital in Bangladesh. [PDF]
Public Health ChallThis study applies queuing theory models (M/M/c/c and M/M/c/K) to optimize inpatient flow and resource allocation in the cardiology department of Sylhet MAG Osmani Medical College Hospital, Bangladesh. Using data from 6,277 patients in 2023, it identifies bottlenecks in CCU and PCCU, highlights bed shortages and overcrowding, and proposes reallocating ...

Queueing System with Potential for Recruiting Secondary Servers
Mathematics, 2023 In this paper, we consider a single server queueing system in which the arrivals occur according to a Markovian arrival process (MAP). The served customers may be recruited (or opted from those customers’ point of view) to act as secondary servers to ...

On Probability Characteristics for a Class of Queueing Models with Impatient Customers
Mathematics, 2020 In this paper, a class of queueing models with impatient customers is considered. It deals with the probability characteristics of an individual customer in a non-stationary Markovian queue with impatient customers, the stationary analogue of which was ...

Multi-server Markovian heterogeneous arrivals queue with two kinds of working vacations and impatient customers [PDF]
Yugoslav Journal of Operations Research, 2023 This paper deals with multi-server queueing system with two kinds of Working Vacations (WVs) and impatient customers. A random timer is started whenever a customer comes into the system. The customer may abandon the system if the service is not completed

The expected discrimination frequency for two-server queues
Operations Research Perspectives, 2018 Fairness measures for queues were introduced for measuring the individual satisfaction of human customers with respect to the waiting experience. The measure which performs best in some sense is the expected discrimination frequency (DF).

Large Deviations for Hawkes Processes with Randomized Baseline Intensity
Mathematics, 2023 The Hawkes process, which is generally defined for the continuous-time setting, can be described as a self-exciting simple point process with a clustering effect, whose jump rate depends on its entire history.

AN \(M^{[X]}/G/1\) QUEUE WITH OPTIONAL SERVICE AND WORKING BREAKDOWN
Ural Mathematical Journal, 2023 In this study, a batch arrival single service queue with two stages of service (second stage is optional)Â and working breakdown is investigated. When the system is in operation, it may breakdown at any time.
