The M/M/c queueing model is a mathematical framework used to analyze systems with multiple servers. In this model, "M" stands for "Markovian," indicating that arrival and service times follow an exponential distribution. The "c" represents the number of servers available to handle incoming requests, making it suitable for environments like call centers or service desks. This model helps predict performance metrics such as average wait time and system utilization. By understanding these metrics, organizations can optimize resource allocation and improve service efficiency, ensuring that customer demands are met effectively while minimizing wait times.
