Mathematics, 2022 The purpose of this article is to examine the server activation policy (SAP) in a multi-server queuing-inventory system (MQIS). The queue has a total of c number of multi-threshold stages as well as c-homogeneous servers.

Mathematics, 2022 A multi-server queueing system with two types of requests and preemptive priority of one type is considered as a model of a cell of a cognitive radio system under practical suggestions about the arrival flows. A hysteresis type strategy for server reservation is suggested to mitigate the effect of interruption of service of low priority requests. Under

On a batch arrival queuing system equipped with a stand-by server during vacation periods or the repairs times of the main server [PDF]
, 2011 We study a queuing system which is equipped with a stand-by server in addition to the main server. The stand-by server provides service to customers only during the period of absence of the main server when either the main server is on a vacation or it ...

IET Generation, Transmission &Distribution, Volume 17, Issue 20, Page 4554-4573, October 2023., 2023 This paper provides an industrial internet of things (IoT) infrastructure solution based on a newly designed low‐cost microcontroller‐based IoT RTU to integrate new, old, and conventional sites of existing grids with smart grids. The IoT RTU supports Wi‐Fi communication and includes digital/analog inputs and outputs besides the advantage of serial data

Mathematical Methods in the Applied Sciences, Volume 46, Issue 6, Page 6756-6766, April 2023., 2023 This paper is concerned with level‐dependent quasi‐birth‐death (LD‐QBD) processes, i.e., multi‐variate Markov chains with a block‐tridiagonal q$$ q $$‐matrix, and a more general class of block‐structured Markov chains, which can be seen as LD‐QBD processes with total catastrophes.

Analysis of Interconnected Arrivals on Queueing-Inventory System with Two Multi-Server Service Channels and One Retrial Facility [PDF]
Electronics, 2021 Present-day queuing inventory systems (QIS) do not utilize two multi-server service channels. We proposed two multi-server service channels referred to as T1S (Type 1 n-identical multi-server) and T2S (Type 2 m-identical multi-server). It includes an optional interconnected service connection between T1S and T2S, which has a finite queue of size N.

Performance analysis of single server non-markovian retrial queue with working vacation and constant retrial policy [PDF]
, 2014 This paper analyses an M/G/1 retrial queue with working vacation and constant retrial policy. As soon as the system becomes empty, the server begins a working vacation. The server works with different service rates rather than completely stopping service

Multiserver Retrial Queue with Two-Way Communication and Synchronous Working Vacation
MathematicsThis work investigates a two-way communication retrial queue with synchronous working vacation and a constant retrial policy. During the idle time, a server makes an outgoing call after a random length.

International journal of Computer Networks & Communications, 2023 This study presents the usage of retrial queues with cloud computing systems in which the operating unit (the server) and the storing unit (buffer) are independently considered. In fact, the tasks cannot occupy the server to the system. Instead, they are stored in the buffer and sent back to the server after a random time.
