Queueing Theory

Queueing theory is a field of study that examines the dynamics of queues. In essence, it seeks to understand and analyse all aspects of situations where individuals or entities must wait for service, including wait times, queue lengths, and service capacity.

Understanding Queue Systems

A queue system is a structured framework comprising customers requiring service, service facilities (servers), and rules governing customer arrivals and service order. Simple examples include queues at supermarket checkouts, cinema ticket counters, or vehicles at traffic lights.
