Q134. Consider a system for a flu vaccine clinic. People arrive at some random or fixed rate and queue up. Our first station (F) has to get them to fill out a form, sign some papers, etc. After this they get in the line for the actual shots (at station V). We have a fixed number of staff whom we will divide between the two stations, depending on the size of the queues. Draw the stock and flow diagram for the system and write the equations for Q1, Q2, F and V.
