Assessing the Operational Safety of New Energy Truck Platoons Under Information Uncertainty and Longitudinal Slope

Journal of Advanced Transportation, Volume 2026, Issue 1, 2026.
Autonomous truck platooning represents a transformative advancement in modern highway logistics, offering substantial benefits in fuel efficiency and traffic throughput. However, the practical deployment of such systems is frequently compromised by sensing limitations and environmental factors, particularly localization uncertainty and varying ...

Preemptive Priority Markovian Queue Subject to Server Breakdown with Imperfect Coverage and Working Vacation Interruption

Computation, 2023
This work considers a preemptive priority queueing system with vacation, where the single server may break down with imperfect coverage. Various combinations of server vacation priority queueing models have been studied by many scholars.

Exponential bounds for queues with Markovian arrivals

Queueing Systems, 1994
The main results of the paper deal with the bounds of the queue length distribution. Particularly, for the case of Markovian arrivals the exponential upper bounds are derived. These results are commented in the framework of several examples.

A Pincherle‐Type Convergence Theorem for Generalized Continued Fractions in Banach Algebras

Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.
This contribution is dedicated to the interdependence of higher order linear difference equations and generalized continued fractions in Banach algebras. It turns out that the computation of certain subdominant solutions of a higher order linear difference equation can be done more efficiently by considering its adjoint equation.

Construction and Optimization of a Cost Function in a Single‐Server Multiphase Queueing System With Hypoexponential‐k Customer Service Time

Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.
In this paper, a new generalized cost function construction for a single‐server multiphase queueing system with a Poisson input stream, hypoexponential‐k customer service time, and FIFO discipline is presented. A proposed relationship between service parameters in k phases is based on a geometric progression with rate α, 0 < α < 1.

ANFIS computing and cost optimization of an M/M/c/M queue with feedback and balking customers under a hybrid hiatus policy

Croatian Operational Research Review
The present investigation studies a hybrid hiatus policy for a finite-space Markovian queue, incorporating realistic features such as Bernoulli feedback, multiple servers, and balking customers. A hybrid hiatus policy combines both a working hiatus and a

Analysis of Switching the Purchase Option in a Two‐Commodity Perishable Inventory System

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This research examines a queueing‐inventory model that includes two perishable commodities, each having a distinct lifetime, service duration, lead time, and individual (s, Q) ordering policy. The system consists of two finite‐capacity waiting zones for two distinct types of clients, with arrivals governed by independent Poisson processes.

Splitting for a non-Markovian tandem queue

, 2021
In this talk, we consider a non-Markovian tandem queue and we use splitting in order to estimate the probability that the total number of customers in this tandem queue reaches some high level N during a busy cycle of the system.

Probabilistic analysis of buffer starvation in Markovian queues [PDF]

2012 Proceedings IEEE INFOCOM, 2012
Our purpose in this paper is to obtain the \emph{exact distribution} of the number of buffer starvations within a sequence of $N$ consecutive packet arrivals. The buffer is modeled as an M/M/1 queue. When the buffer is empty, the service restarts after a certain amount of packets are \emph{prefetched}.

Navigating the Waves: The Global Pandemic's Impact on Container Shipping and Freight Rates Across Different Policy Scenarios

Naval Research Logistics (NRL), Volume 72, Issue 7, Page 975-993, October 2025.
ABSTRACT The COVID‐19 pandemic has reverberated across global industries, including the international container shipping industry, where freight rates have become highly volatile. However, shipping lines appeared to thrive, particularly during the pandemic's initial 2 years.
