Introduction

Queueing theory is a branch of applied probability and operations research that studies waiting lines, service processes, and system performance. Mathematical queueing models help researchers understand congestion, estimate waiting times, evaluate server utilization, and assess operating costs. These models can be applied to communication networks, cloud services, manufacturing, healthcare, and other environments where demand competes for limited service capacity.

Visakan’s publication record addresses several variations of retrial queues, including feedback, working vacations, breakdowns, and customer impatience. These topics extend classical queueing models to represent service conditions that are closer to real operational systems. (1)

Research Profile

His documented research interests include queueing theory and heuristic optimization. Research in these areas combines probabilistic analysis, mathematical modelling, and numerical optimization to study complex service systems. His academic profile identifies Joy University as his current institutional affiliation and records publications in mathematics and operations research journals. (1) His ORCID record provides a persistent identifier for connecting his research identity with scholarly outputs. (3)

Research Contributions

Visakan’s research explores analytical and computational approaches to queueing systems with repeated service attempts, changing server availability, and cost constraints. One study develops a mathematical model for a double orbital queue with recurrent customers under a working-vacation policy and examines optimal control using the whale optimization algorithm. (4) Another publication investigates retrial queues with hybrid vacation policies and fault correction, applying metaheuristic methods to cost optimization. (5)

Such studies contribute to the mathematical understanding of service systems by combining steady-state analysis, performance measures, and optimization. Their potential applications include improving resource allocation, reducing congestion, and balancing operating costs against service quality.
