For me it is the fact that our blood contains iron. I earlier used to believe the word stood for some ‘organic element’ since I couldn’t accept we had metal flowing through our supposed carbon-based bodies, till I realized that is where the taste and smell of blood comes from.

    Queuing theory can have some fun surprises.

    Suppose a small bank has only one teller. Customers take an average of 10 minutes to serve and they arrive at the rate of 5.8 per hour. With only one teller, customers will have to wait nearly five hours on average before they are served. If you add a second teller the average wait becomes 3 minutes.

      Can you elaborate on the math here? (I believe you, I just want to understand the simulation parameters better).

          Also, in this simulation are the customers arriving in equally spaced intervals or is random arrival time within the bounds assumed?

          Aren’t they arriving slightly slower than can be served, according to these numbers:

          If one customer takes 10 minutes to serve, you can serve 6 customers in an hour

          and you get 5.8 customers every hour, which is less than 6

          So you serve 6 customers, meaning you have a leftover capacity of 0.2 per hour or 1 extra customer every 5 hours

          Maybe the numbers are switched over or I am misunderstanding something

          Thanks! This article really clears up a lot of the details that help the simulation make sense.

        Intuitive way to see why is that 6.1 customers per hour would mean infinite waiting time (when it reaches a steady state)
