On two-queue Markovian polling systems with exhaustive service [PDF]

, 2014
We consider a class of two-queue polling systems with exhaustive service, where the order in which the server visits the queues is governed by a discrete-time Markov chain.

Semi‐Markovian planning to coordinate aerial and maritime medical evacuation platforms

AI Magazine, Volume 46, Issue 3, Fall 2025.
Abstract The transfer of patients between two aircraft using an underway watercraft increases medical evacuation reach and flexibility in maritime environments. The selection of any one of multiple underway watercraft for patient exchange is complicated by participating aircraft utilization histories and participating watercraft positions and ...

Two-types of service facilities in interconnected stochastic queueing and queueing-inventory system with marked Markovian arrival process

Ain Shams Engineering Journal
This article explores the performance of interconnected queueing systems and queueing-inventory systems (IQSQIS) in stochastic modeling. IQSQIS features two types of service facilities with dual service stations: one providing non-commodity service with ...

Conditional Aalen–Johansen estimation

Scandinavian Journal of Statistics, Volume 52, Issue 2, Page 873-902, June 2025.
Abstract The conditional Aalen–Johansen estimator, a general‐purpose nonparametric estimator of conditional state occupation probabilities, is introduced. The estimator is applicable for any finite‐state jump process and supports conditioning on external as well as internal covariate information.

A Comparative Analysis of (s, Q) and (s, S) Ordering Policies in a Queuing-Inventory System with Stock-Dependent Arrival and queue-dependent service process [PDF]

Operations Research and Decisions, 2023
This article deals with a Markovian queuing-inventory system (MQIS) under the stochastic modeling technique. The arrival stream of this system is dependent on the present stock level at an instant.

Resilience assessment of urban rail transit stations considering disturbance and time‐varying passenger flow

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 12, Page 1627-1651, 9 May 2025.
Abstract Unlike most urban rail transit (URT) resilience studies on URT lines or networks under major disturbances, this paper focuses on the resilience assessment of URT stations under high‐frequency daily disturbances with minor impacts. A resilience assessment metric with different resilience levels is proposed, which is calculated based on multiple
