Excursion theory for Markov processes indexed by Lévy trees

Proceedings of the London Mathematical Society, Volume 132, Issue 5, May 2026.
Abstract We develop an excursion theory that describes the evolution of a Markov process indexed by a Lévy tree away from a regular and instantaneous point x$x$ of the state space. The theory builds upon a notion of local time at x$x$ that was recently introduced in the companion paper [Probab. Theory Related Fields. 189 (2024), 1–99].

Reliability assessment of cyber physical distribution systems including sequential scenario simulation correction and recovery resource decisions

Energy Conversion and Economics, Volume 7, Issue 1, Page 37-49, February 2026.
Abstract With the deepening of research on smart grids, the distribution system has gradually evolved into a cyber‐physical distribution system (CPDS). The refined reliability modelling and assessment methods for CPDS are of great significance. This paper proposes an integrated reliability assessment framework combining distribution information system (

Priority Auctions and Queue Disciplines that Depend on Processing Time [PDF]

, 2004
Lecture on the first SFB/TR 15 meeting, Gummersbach, July, 18 - 20, 2004We analyze the allocation of priority in queues via simple bidding mechanisms. In our model, the stochastically arriving customers are privately informed about their own processing ...

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.

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}.

Flexible Scheduling for Large‐Scale Autonomous Driving Trucks in Open‐Pit Mining With Reinforcement Learning‐Assisted Evolutionary Programming

IET Cyber-Systems and Robotics, Volume 8, Issue 1, January/December 2026.
ABSTRACT Deployment of autonomous driving trucks (ADTs) in open‐pit mining enables more flexible transport operations than human‐driven trucks; but this flexibility significantly expands the scheduling search space and makes it more difficult to find near‐optimal solutions on large scales.

Stochastic Monotonicity of Markovian Multiclass Queueing Networks [PDF]

Stochastic Systems, 2019
Multiclass queueing networks (McQNs) extend the classical concept of the Jackson network by allowing jobs of different classes to visit the same server. Although such a generalization seems rather natural, from a structural perspective, there is a significant gap between the two concepts. Nice analytical features of Jackson networks, such as stability

Fuzzy States to Enhance Train Delay Prediction of Markov Chains

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This study introduces Markov chains with fuzzy delay states with triangular membership functions for the first time to model train delay predictions. It is shown that the prediction errors can be reduced by the fuzzification adoption. ABSTRACT Markov chains provide distinctive advantages and practical applicability in modeling of train delays.

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

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.
