Queue model analysis of airline check-in offices with simulation approach.

Currently, business processes in the community often get complaints about long queues, which also happened at the Batik Air check-in office at Kualanamu International Airport. This study was conducted to evaluate the queuing model at the Batik Air check-in office and to determine whether the model is the optimal model or needs some updating to optimize the queue. The airline's current queuing system is two queue lines with two counters. The average service time is 166.5 seconds, and the average arrival time is 119 seconds. Previous observation data shows that the average service time for counter 1 is 159 seconds, and counter 2 is 174 seconds. This data indicates that there is a long queue at the check-in counter. From the simulation system test, the result of changing two queuing lines to 3 queuing lines with three counters is the most optimal queuing system model. There had been an increase of customers number served by ten people from 34 customers or 29.4%, with the percentage of customers at each counter being 20% for counter 1, 50% for counter 2, 30% for counter 3.
