Question 1
One subway station in Toronto has 6 turnstiles, each of which can be controlled by the station manager to be used for either entrance or exit control – but never for both. The manager must decide at different times of the day just how many turnstiles to use for entering passengers and how many to be set up to allow exiting passengers.
Suppose that passengers enter the station at a rate of about 84 per minute between the hours of 7 and 9 A.M. Passengers exiting trains at the stop reach the exit turnstile area at a rate of about 48 per minute during the same morning rush hours. Each turnstile can allow an average of 30 passengers per minute to enter or exit. Arrival and service times have been thought to follow Poisson and exponential distributions, respectively. Assume riders form a common queue at both entry and exit turnstile areas and proceed to the first empty turnstile.
The station manager does not want the average passenger at his station to have to wait in the turnstile line for more than 6 seconds, nor does he want more than 8 people in any queue at any average time.
a) How many turnstiles should be opened in each direction every morning?
b) Discuss the assumptions underlying the solution of this problem using queuing theory.
