With the number of facility service as many as 2 people, the discipline used is the customer who comes first will be served first (first come first serve). The queue model used is (M/M/2):(FCFS/~/~), meaning the number of arrivals uses Poisson distribution and the service time uses exponential distribution. This simulation is run for 6 hours with 10-time replication, verified and is then validated. Considering that, an analysis of the queues at the payment counters using pro model software application is made to anticipate the long queues. It is also caused by some factors such as a small number of cash registers, with only 2 counters functioned irregularly and less extensive queue lines. The problem found in this study is a long queue at the payment counter resulting from numerous customers who come to POS Company. Simulation is a process of imitation of a tangible thing and its surroundings.
