Assume the waiting lines at the receptionist, the nurse clinician, and the doctor are managed independently with a FCFS priority. Model this system using ServiceModel to determine the utilization of each resource (receptionist, nurse clinician, and physician) and the distribution of time in the system for an arriving patient. Begin by selecting the Build menu – Background Graphic – Behind Grid. Then select the Edit menu – Import Graphic – Pracmod. This will give you an office floor plan on which you can arrange furniture.
