M/M/c queue

An M/M/c queue is a mathematical model used to describe systems where customers arrive randomly, are served by multiple servers simultaneously, and experience waiting times if servers are busy. "M/M/c" stands for "Markovian arrivals," "Markovian service times," and "c" servers. It assumes customer arrivals and service times follow exponential distributions, meaning they are memoryless. This model helps analyze system performance, such as average waiting time and utilization, crucial for optimizing service facilities like call centers, banks, or hospitals with multiple service points.
