Analysis Of Queuing Models Of Fast Food Restaurant with Simulation Approach

Abstract

Queues in the cashier area in food purchases is one of the problems that often occurs in business processes in the community. Queues occur because of an imbalance between those served and their services. In fast food restaurants like XYZ, queues generally occur during lunch breaks or at dinner time. The purpose of this study is to determine the queuing model that occurs in the XYZ cashier area and analyze whether the queuing model is appropriate and efficient by comparing the previous model with the simulation results that have been carried out with the help of Anylogic software. The restaurant queue system is 3 queue lines and 3 counters. The average length of service and the interval of arrival of workers is 125.1 seconds and 67.5 seconds. Preliminary observational data show the average service time counters 1, 2 and 3 are 111, 136, 138 seconds. This fact shows that there is a long queue, the number of customers served at relatively low time units and work imbalances between operators. The results of the best queue simulation are proven to have shorter queues and the highest number of customers served per unit time. Based on the simulation results obtained by replacing 3 queue lines into 1 queue line and increasing the number of customers served is 74 people from 129 customers with the percentage of customers at each counter that is 28.38% for counter 1, 27.03% for counters 2 and 44, 59% for counter 3.
