At a taxi-stop on a busy street, the inter-arrival times of taxis dropping off passengers (and then being ready for the pick up) have a mean 5 minutes with a standard deviation 1 minute. The taxis are not allowed to wait for customers at the stop. Customers arrive at the stop in a Poisson process once every 6 minutes on the average.

(a) Determine the expected number of customers waiting, when a taxi leaves the stop.

(b)What is the probability that there would be no waiting customer, when a taxi leaves the stop?

(c) Determine the mean waiting time of a customer.

1.1 (M/M/1) model - use the qtsPlus or other software to answer the questions. In a grocery store, there is one cashier. Customers arrive at the cashier counter according to a Poisson process. The arrival rate is 18 customers per an hour. Customers are served in order of arrival (FCFS: first come first service). The service time (i.e. the time needed for scanning the items and processing payment) is exponentially distributed. The mean service time is 3 minutes. A) Once...

To manage their rental counter, Too Late can add a computerized check-in option. Upon arrival, customers will first go to the check-in machine, enter their reference number, (electronically) sign a waiver, and make a payment. After this step is complete, the customer will go to the attendant on duty to receive the vehicle’s keys and directions to its parking location. If a customer arrives at the check-in station and finds that it is being used by another customer, the incoming...
