Modeling and Simulation Hand Simulation Exercises 5th February 2023 Question 1 A scenario for H & A Optical Centre is provided below. Arrival time refers to the time a patient arrives and consultation time is the time the patient spends time in the consultation room and does not involve the waiting time. It is assumed that the departure time of previous customer is the starting time of the next customer i.e. no time delay. Customer Number Arrival Consultation Time Time (min) 1 0.00 3.00 2 2.00 2.50 3 3.00 3.00 4 3.80 4.50 5 4.20 4.50 6 8.00 4.00 7 10.30 2.00 8 13.50 2.50 9 16.00 5.00 10 20.00 2.50 Perform a hand simulation and stop the simulation when all the patients have been served. Calculate the following and determine whether there is need to hire another consultant . i) Average waiting time of the patients before they are served. ii) What is the maximum waiting time before being served. iii) Average time between arrivals
