Journal of Engineering, Volume 2026, Issue 1, 2026.Global supply chains are increasingly vulnerable to fraud, counterfeiting, and inefficient data management, leading to significant financial losses and operational disruptions. This paper presents a conceptual framework that leverages blockchain technology, radio‐frequency identification (RFID), and decentralized storage (IPFS) to enhance traceability,

Analysis of a Retrial Queue With Two-Type Breakdowns and Delayed Repairs
IEEE Access, 2020 This article studies an M/G/1 retrial queue with two types of breakdowns. When the server is idle, it is subject to breakdowns according to a Poisson process with rate δ and it cannot be repaired immediately.

Analysis of Switching the Purchase Option in a Two‐Commodity Perishable Inventory System
Journal of Mathematics, Volume 2026, Issue 1, 2026.This research examines a queueing‐inventory model that includes two perishable commodities, each having a distinct lifetime, service duration, lead time, and individual (s, Q) ordering policy. The system consists of two finite‐capacity waiting zones for two distinct types of clients, with arrivals governed by independent Poisson processes.

, 2014 We are concerned with the problem of characterizing the distribution of the maximum number Z(t(0)) of customers during a fixed time interval [0, t(0)] in the M/M/c retrial queue, which is shown to have a matrix exponential form.

Analysis of classical retrial queue with differentiated vacation and state dependent arrival rate.
Ratio Mathematica, 2021 In present paper we have introduced the concept of differentiated vacations in a retrial queueing model with state dependent arrival rates of customers. The arrival rate of customers is different in various states of the server.

Simulating a Quantum Switch With Concurrent Demands
Concurrency and Computation: Practice and Experience, Volume 37, Issue 27-28, 25 December 2025.ABSTRACT Quantum networks rely on entanglement distribution to enable secure communication and distributed quantum computation. Most analytical models address idealized, single‐flow scenarios and overlook the impact of concurrent entanglement requests, limiting their applicability to realistic network conditions.

Discrete-time retrial queue with Bernoulli vacation, preemptive resume and feedback customers
Journal of Industrial Engineering and Management, 2015 Purpose: We consider a discrete-time Geo/G/1 retrial queue where the retrial time follows a general distribution, the server subject to Bernoulli vacation policy and the customer has preemptive resume priority, Bernoulli feedback strategy.

Mathematics, 2022 The use of a Markovian inventory system is a critical part of inventory management. The purpose of this study is to examine the demand for two commodities in a Markovian inventory system, one of which is designated as a major item (Commodity-I) and the ...
