Assignment 4: Discrete Event Simulation At a doctors office, a patient arrives on average once every 20 minutes. Patients first have to go to a unique check-in desk staffed by a medical assistant, providing their name and insurance data. This process takes from 30 seconds and 2 minutes. After that, patients have to sit in the waiting room, until the doctor is available. The doctor calls the patients in the same order they arrived. The check-up time with the doctor take on average 15 minutes, with a standard deviation of 3 minutes. After the check-up, about half of the patients need a prescription, the doctor writes the prescription in 1 minute, on average. Both prescription and non-prescription patients go to the check-out desk to pay the fee and schedule the next appointment. This typically takes 45 seconds. The same medical assistant is staffing the check-in and the check-out desks. Model the doctors office in Arena and simulate this model for 10 replications of 8 hours. On average, what is the total time spent in the office by a patient? What is the maximum waiting time in the waiting room? The doctor is considering to hire a second medical assistant to have an assistant specifically assigned to the check-in and check-out processes. Implement this change in the model. Is this a good idea? Submit the Arena models for question 1 and 4. Submit a text file with your answers to questions 2 and 3. Mention what part of the report you retrieved the answer from.
