QUEUE RANKING, BALKING AND VARIABLE DISPLAYS AND HISTOGRAMS. Objective: Introducing the concepts of Queue ranking, Balking, variable displays and generating histograms. Things to do: Model: Build a single server model for a banking system where the customers arrive at a bank for teller services. The model should calculate the average time spent by the customer in the bank. The details are given below.

Interarrival time Service time Run length Base time units Radio: Exp (10) min. Normal (15,2) 250 Customers Minutes Part A: Change the default ranking of the queues from FIFO to LIFO, LowestAttribute Value and Highest Attribute Value options and compare the results for time in the system. From the Simon Report write the value for time in system for all the rankings given

Ranking FIFO LIFO LAV HAV Time in System Part B: The customer enters the queue only if a customer finds the teller queue length to be less than 10, else he leaves the system. This is called balking. Add a DECIDE module and give this condition selecting the 2-way-by-condition option. Obtain the average time between balking using RECORD module. From the Simon Report write the value for time in system and time between balking.

Statistic Time in System Time Between Balking Result

Using HISTOGRAM option from animation bar, place histograms for time in the system for the customers served and time between balking for the customers leaving the system without service.

Part C: Using VARIABLE option from animation bar, place variables to display the number of customers leaving the system with service and without service. Place a variable that shows the current number of customers in the teller queue. Part D: Using HISTOGRAM option from animation bar, place histograms for time in the system for the customers served and time between balking for the customers leaving the system without service.
