Operations Research PerspectivesThe superposition of arrival processes is a fundamental yet analytically intractable operation in queueing networks when inputs are general non-renewal streams.

Ratings design and barriers to entry
Theoretical Economics, Volume 21, Issue 3, Page 775-809, July 2026.I study the impact of consumer reviews on the incentives for firms to participate in the market. I develop a model of endogenous entry in which firms produce goods of heterogeneous, unknown quality. Consumers engage in directed search, and prices are exogenously fixed.

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 ...

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].

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 (

Transient bayesian inference for short and long-tailed GI/G/1 queueing systems [PDF]
, 2005 In this paper, we describe how to make Bayesian inference for the transient behaviour and busy period in a single server system with general and unknown distribution for the service and interarrival time.

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}.

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.

Departure processes from MAP/PH/1 queues [PDF]
, 1999 A MAP/PH/1 queue is a queue having a Markov arrival process (MAP), and a single server with phase-type (PH -type) distributed service time. This thesis considers the departure process from these type of queues.
