Abstract：In the supermarket cashier service system, the customer\'s strategy of counter selection affects the service quality and customer experience of the supermarket.Two counter selection strategies are designed and modeled.A multi-server queueing model is established to evaluate the performance measures of the strategies in form of average queue length and average waiting time. Through simulation and numerical results, the performance is better when the customer chooses the shortest queue. The improvement becomes greater when the variance of serve rate of each counter increases. In conclusion, the choosing-short-queue strategy outperforms random strategy under the simulated sircumstances. That is to say, choosing a better queuing method has a greater impact on the average waiting time of the average captain and the average customer.According to this research, the manager of supermarkets could guide the customer to make better counter selection to improve the service quality and customer experience of supermarkets.
