Summary Introduction

To determine: The number of tellers that the bank should hire.

Introduction: In order to predict the waiting time and length of the queue, queueing model will be framed. Queueing theory is the mathematical model that can be used for the decision-making process regarding the resources required to provide a service.

A small bank is trying to determine how many tellers toemploy. The total cost of employing a teller is $100 per day,and a teller can serve an average of 60 customers per day.An average of 50 customers per day arrive at the bank, andboth service times and interarrival times are exponential. Ifthe delay cost per customer-day is $100, how many tellersshould the bank hire?
Using an M/M/1 queuing system as an example demonstrate how the event list in a simulation model would evolve over 5 discrete steps if the first part will arrive at time zero, the time between the next four arrivals are 3, 5, 6, and 4 minutes and that the machining times for the first five parts are 6, 4, 3, 5, and 4 minutes. The performance metrics of interest are the average queue length and the number of items processed.
A crew of mechanics at the Transylvania Department of Motor Vehicles garage make minor repairs to snowplows during the winter.  The snowplows break down at an average rate of  4 vehicles per day and breakdowns are distributed according to the Poisson distribution. The mechanic can service an average of 7 vehicles per day with a repair time distribution that approximates a negative exponential distribution.  Assume an 8 hour day. Approximately how many vehicles are in the garage, waiting for or being repaired?
