The expected discrimination frequency for two-server queues [PDF]
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).

Approximate analysis of non-stationary loss queues and networks of loss queues with general service time distributions [PDF]
, 2011 A Fixed Point Approximation (FPA) method has recently been suggested for non-stationary analysis of loss queues and networks of loss queues with Exponential service times.

IEEE Access, 2019 We consider the customers' strategic behavior in Markovian queues with negative customers and working breakdowns. when a negative customer arrives, the customer being served is forced to leave the system.

Discussion on the Transient Behaviour of Single Server Markovian Multiple Variant Vacation Queues
Operations Research and Decisions, 2021 We consider an M/M/1 queue where beneficiary visits occur singly. Once the beneficiary level in the system becomes zero, the server takes a vacation at once.

Setting staffing requirements for time-dependent queueing networks: the case of accident and emergency departments [PDF]
, 2012 An incentive scheme aimed at reducing patients’ waiting times in accident and emergency departments was introduced by the UK government in 2000. It requires 98% of patients to be discharged, transferred, or admitted to inpatient care within 4 hours of ...

Modeling the Multi-channel Section in the Supply Chain System using the Multiserver Queue Analogy
Jurnal Teknik Industri, 2021 The industry generally consists of a supply chain system. The main constituents of any supply chain system are suppliers, manufacturers, distribution centers, and retailers.

Coupled queues with customer impatience [PDF]
, 2018 Motivated by assembly processes, we consider a Markovian queueing system with multiple coupled queues and customer impatience. Coupling means that departures from all constituent queues are synchronised and that service is interrupted whenever any of the

Inter-Departure Time Correlations in PH/G/1 Queues
MathematicsIn non-Markovian tandem queueing networks the output process of one site, which is the input process to the next site, is not renewal. Consequently, the correlation analysis of that output processes is essential when studying such networks. A correlation

An innovative modelling proposal for the blood supply chain
Vox Sanguinis, EarlyView.Abstract Whole‐blood donation and apheresis are the only ways to obtain blood components for human use. Tools are being developed to improve the efficiency of blood donation systems by reducing waste, increasing donations and preventing shortages.

Acta Crystallographica Section D, Volume 82, Issue 6, Page 638-645, June 2026.We present a quantitative framework combining cost modelling and queueing theory to estimate hourly access costs, waiting times and congestion levels for shared high‐end scientific equipment. The approach is general, illustrated with cryo‐electron microscopy examples, and implemented in an open‐access online calculator to support evidence‐based ...
