Service Time Distributions

Service time distributions describe the variability in how long it takes to complete a particular service or task. Instead of assuming a fixed time, they acknowledge that service durations can vary due to different factors. These distributions help analyze and predict system performance, such as waiting times and queue lengths, by providing a probabilistic understanding of how long services might take. Common types include exponential, normal, or uniform distributions, each characterizing different patterns of variation. Using these models enables better planning, resource allocation, and management of service systems like customer support, manufacturing, or healthcare.
