A queueing model with server breakdowns, repairs, vacations, and backup server
Operations Research Perspectives, 2020 Queueing models wherein having a backup server during the absences (caused by vacations and breakdowns) of the main server have found many applications in practice.

Computational Analysis of a Multi-Server Bulk Arrival with Two Modes Server Breakdown [PDF]
Mathematical and Computational Applications, 2005 An extensive Monte Carlo study is performed to analyze a multi-server, bulk arrival (M [x]M/C; C-1/FCFS) queuing system. The system breakdown limits the system to serve with either C or (C-1) servers. The server breakdown has equal chance over all servers in the system while the arrival process is a Poisson process and the distribution of the bulk size

Mathematics, 2018 In this paper, we discuss a non-Markovian batch arrival general bulk service single-server queueing system with server breakdown and repair, a stand-by server, multiple vacation and re-service.

AEJ - Alexandria Engineering Journal, 2018 In this paper, we consider a single server feedback retrial queueing system with multiple working vacations and vacation interruption. An arriving customer may balk the system at some particular times.

Computational Analysis of a Multi-Server Bulk Arrival with Two Modes Server Breakdown [PDF]
The Egyptian Statistical Journal, 2003 A Monte Carlo study is performed to analyze a multi-server, bulk arrival (M(x)/M/C; C-1/FCFS) queuing system. The system breakdown limits the system to serve with either C or (C-1) servers.

Steady-State Analysis of a Flexible Markovian Queue with Server Breakdowns [PDF]
Entropy, 2019 A flexible single-server queueing system is considered in this paper. The server adapts to the system size by using a strategy where the service provided can be either single or bulk depending on some threshold level c.

Analysis of heterogeneous two server queueing system with multiple working vacations and server breakdowns [PDF]
Yugoslav Journal of Operations ResearchA generalized fuzzy number (GFN), whose height is not necessarily 1, is used in situations when expert opinions are not completely reliable. This subnormality complicates operations based on the extension principle.

Cost Optimization using Genetic Algorithm in Customers Intolerance Markovian Model with Working Vacation and Multiple Working Breakdowns [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2022 In this paper, we consider a single server queueing model with working vacation and multiple working breakdowns. When on vacation, the server works at a different pace. Disturbances occur in the server due to multiple breakdowns.

Performance analysis of an M/G/1 retrial G-queue with feedback under working breakdown services [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2020 In this paper, we investigate a new type of retrial queueing model with feedback and working breakdown services. The regular busy server may become defective by disasters (negative customers) at any point of time.
