Järjekorrakäsitlus, often translated as "queueing theory" or "waiting line theory," is a mathematical study of waiting lines or queues. It analyzes systems where entities, such as customers, data packets, or jobs, arrive and wait for a service. The primary goal of queueing theory is to understand and optimize the performance of these systems by studying factors like arrival rates, service rates, the number of servers, and the queue discipline.

The fundamental components of a queueing system include the arrival process, the queue itself, the service mechanism, and the queue discipline. The arrival process describes how entities enter the system, often modeled by probability distributions such as the Poisson distribution. The queue is where entities wait if all servers are busy. The service mechanism refers to how entities are processed, characterized by service times and the number of available servers. Queue discipline determines the order in which waiting entities are selected for service, with common examples being First-Come, First-Served (FCFS) or Last-Come, First-Served (LCFS).

Queueing theory provides tools and models to predict key performance metrics like average waiting time, average queue length, system utilization, and the probability of an entity having to wait. These insights are crucial for resource allocation and system design across various fields. Applications range from managing customer service desks and call centers to optimizing traffic flow, computer network performance, and manufacturing processes. By understanding these dynamics, organizations can make informed decisions to improve efficiency, reduce costs, and enhance customer satisfaction.
