Analysis of a Semi-Open Queuing Network with a State Dependent Marked Markovian Arrival Process, Customers Retrials and Impatience

Mathematics, 2019
We consider a queuing network with single-server nodes and heterogeneous customers. The number of customers, which can obtain service simultaneously, is restricted.

Two-types of service facilities in interconnected stochastic queueing and queueing-inventory system with marked Markovian arrival process

Ain Shams Engineering Journal
This article explores the performance of interconnected queueing systems and queueing-inventory systems (IQSQIS) in stochastic modeling. IQSQIS features two types of service facilities with dual service stations: one providing non-commodity service with ...

Mathematical Model of Operation of a Cell of a Mobile Communication Network With Adaptive Modulation Schemes and Handover of Mobile Users

IEEE Access, 2021
A model of a cell of a communication network, divided into zones, with the dependence of the users’ service time on the zone, in which they are located, is considered. The arrival flow of users is defined by a marked Markovian process.

MMAP/(PH,PH)/1 Queue with Priority Loss through Feedback

Mathematics, 2021
In this paper, we consider two single server queueing systems to which customers of two distinct priorities (P1 and P2) arrive according to a Marked Markovian arrival process (MMAP). They are served according to two distinct phase type distributions. The

Queueing Inventory System in Transport Problem

Mathematics, 2023
In this paper, we consider the batch arrival of customers to a transport station. Customers belonging to each category is considered as a single entity according to a BMMAP.

Queueing-Inventory with One Essential and m Optional Items with Environment Change Process Forming Correlated Renewal Process (MEP)

Mathematics, 2021
We consider a queueing inventory with one essential and m optional items for sale. The system evolves in environments that change randomly. There are n environments that appear in a random fashion governed by a Marked Markovian Environment change process.

Competitive queueing systems with comparative rating dependent arrivals

Operations Research Perspectives, 2020
We consider the joint operation of two multi-server queueing systems. Both systems provide the same type of service and compete for customers. It is assumed that the first system is controlled by ourselves while the second one is controlled by our ...

Performance Evaluation of the Priority Multi-Server System MMAP/PH/M/N Using Machine Learning Methods

Mathematics, 2021
In this paper, we present the results of a study of a priority multi-server queuing system with heterogeneous customers arriving according to a marked Markovian arrival process (MMAP), phase-type service times (PH), and a queue with finite capacity ...
