Abstract

Fast food noodle restaurant is one of the restaurant businesses that are very popular with all levels of society. XYZ Restaurant is one of the famous noodle restaurants in Jember Regency.This restaurant has very long customer queues, especially during peak hours. To overcome these problems, it is necessary to evaluate and optimize the queuing system in its services. The purpose of this research was to determine and analyze the queuing system model applied in that restaurant to formulate recommendations for queuing system improvements that can reduce queue length and minimize queuing costs. The method used is a calculation with queuing theory and simulation using ARENA. The results show that the queuing system model in the current condition is Single Channel MultiPhase. The number of facilities at the cashier is 1 facility with 2 employees and the kitchen facility is 1 facility with 6 employees. Queue discipline used is First In First Out (FIFO). The level of the arrival of customers with Poisson distribution and customer service time with Exponential distribution. Based on the results of several improvement scenarios, the most optimal scenario is by adding 1 cashier facility and 1 kitchen employee. Recommended queue models suitable for cashier facilities are (M/M /2); (FIFO/∞/∞) and kitchen facilities are (M/M/1); (FIFO /∞/∞), with a Multi Channel-Multi Phase queuing system. Costs incurred for the addition of facilities based on selected scenarios are Rp249,833,- per hour which is the most minimal cost.
