Modelling and optimisation of a two-server queue with multiple vacations and working breakdowns
TLDR
This paper presents a steady-state analysis of an M/M/2 queue with heterogeneous servers (Server 1 and Server 2) using the matrix geometric method to compute the stationary distribution of system size and presents numerical results showing the effects of various parameters on the approximate optimal service rates.Abstract:
This paper presents a steady-state analysis of an M/M/2 queue with heterogeneous servers (Server 1 and Server 2). Server 1 is reliable and may leave for a vacation when the system becomes empty. Se...read more

Strategic Behavior of Customers and Optimal Control for Batch Service Polling Systems with Priorities
TL;DR: This paper studies a special batch service polling system (the so-called Israeli queue) with priorities and formulate the revenue function of the service provider and presents the Particle Swarm Optimization algorithm to seek the optimal service prices for the high-priority and low-priority customers to maximize the service providers’ revenue under the two levels of information.

Timely Reliability Analysis of Virtual Machines Considering Migration and Recovery in an Edge Server
TL;DR: In this paper, the authors study the influence of failure, migration, and recovery of VMs in an edge server and build a continuous-time Markov chain (CTMC) to obtain the VMs timely reliability and the end-to-end timely reliability (ETR).

Study on Transient Queue-Size Distribution in the Finite-Buffer Model with Batch Arrivals and Multiple Vacation Policy.
Wojciech M. Kempa,Rafał Marjasz +1 more
TL;DR: In this paper, the transient behavior of the finite buffer queueing model with batch arrivals and generally distributed repeated vacations is analyzed, and a compact-form solution for the corresponding system written for Laplace transforms is obtained using an algebraic approach based on Korolyuk's potential method.

The particle swarm - explosion, stability, and convergence in a multidimensional complex space
M. Clerc,James Kennedy +1 more
TL;DR: This paper analyzes a particle's trajectory as it moves in discrete time, then progresses to the view of it in continuous time, leading to a generalized model of the algorithm, containing a set of coefficients to control the system's convergence tendencies.

Queueing systems with vacations—a survey
TL;DR: This survey gives an overview of some general decomposition results and the methodology used to obtain these results for two vacation models and attempts to provide a methodological overview to illustrate how the seemingly diverse mix of problems is closely related in structure and can be understood in a common framework.
