MM1n

MM1n is a designation that can refer to several different things depending on the context, most commonly within telecommunications and queueing theory.

In the context of queueing theory, MM1n represents a specific type of queuing system. The 'M' signifies a Markovian arrival process, meaning customer arrivals follow a Poisson distribution. The second 'M' indicates a Markovian service process, where service times are exponentially distributed. The '1' denotes that there is a single server in the system. The 'n' typically refers to a finite queue capacity, meaning there is a maximum number of customers that can wait in the system (including those being served). This finite capacity is a key characteristic differentiating it from infinite queue models. Analyzing MM1n systems involves understanding probabilities of system states, average waiting times, and queue lengths, particularly how the finite capacity impacts these metrics compared to unlimited queues.

Alternatively, MM1n might be used in a more general sense within a specific company or project as an internal identifier for a particular model, product, or component. Without further context, it is difficult to ascertain the exact meaning if it diverges from the established queueing theory definition. Its usage in such cases would be specific to the organization or domain where it is employed.
