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.

Non-identifiability of the two state Markovian Arrival process [PDF]
In this paper we consider the problem of identifiability of the two-state Markovian Arrival process (MAP2). In particular, we show that the MAP2 is not identifiable and conditions are given under which two different sets of parameters, induce identical ...

Bulk Queue Model With Optional Service and Service Interruption
Journal of Mathematics, Volume 2026, Issue 1, 2026.In the present article, we investigate a queuing system in which units arrive in random batch sizes according to a Poisson process, while service is provided to individual units on a one‐by‐one basis. The service mechanism comprises a mandatory service phase followed by an optional service phase, undertaken according to the unit’s requirements.

On identifiability of MAP processes [PDF]
Two types of transitions can be found in the Markovian Arrival process or MAP: with and without arrivals. In transient transitions the chain jumps from one state to another with no arrival; in effective transitions, a single arrival occurs.

Stability criteria for controlled queueing networks [PDF]
, 2006 We give criteria for the stability of a very general queueing model under different levels of control. A complete classification of stability (or positive recurrence), transience and null-recurrence is presented for the two queue model. The stability and

Naval Research Logistics (NRL), Volume 72, Issue 7, Page 975-993, October 2025.ABSTRACT The COVID‐19 pandemic has reverberated across global industries, including the international container shipping industry, where freight rates have become highly volatile. However, shipping lines appeared to thrive, particularly during the pandemic's initial 2 years.

Applied SciencesHeterogeneous systems of limited capacity have general applications in manufacturing, but also in logistic or service systems due to the differences in server or workstation performance or work assignment; this is in close relationship with system ...

A Finite Buffer Fluid Queue Driven by a Markovian Queue [PDF]
, 2000 We consider a finite buffer fluid queue receiving its input from the output of a Markovian queue with finite or infinite waiting room. The input flow into the fluid queue is thus characterized by a Markov modulated input rate process and we derive, for a
