Queuing theory is important as a statistical technique for solving problems, analyzing systems, and reducing the adverse effects of waiting. The present research has been done to solve the problem of overcrowding congestion during the distribution of subsidy goods in the Refah chain stores. The purpose of the research is to analyze the queuing system and provide a solution to overcome the crowds in the Refah stores. In this research, a way of providing customer service was reviewed, then customer arrival times, waiting times in queues and customer service were measured. The type of time distribution was followed by Minitab software. Then, the Arena software and the obtained distributions used to simulate the queue system of the store. And the simulation results were used to analyze the queuing system. The results showed that during the distribution of subsidy goods, to fix the queue congestion, 40% of customers should beat the 2nd fund and the rest should equally be divided between the 5th and 6th funds. The implementation of the run-queue system, before the customer enters the funds, is the innovation of this research.
