Basic Queueing - First Arrival Previous Next
We initiate the simulation run with the first arrival (A) having just occurred at time 0, as indicated in the above time line. Since both tellers (servers) are free, this customer immediately begins to receive service from one of them. To determine when the next event (an arrival or a service completion) will occur, we use the inverse transformation method (described in your textbook) to
  1. randomly generate an interarrival time = 0.92653,
  2. randomly generate a service time = 1.76284,
Adding these times to Current Time (0 now) gives
  1. time of next arrival = 0.92653,
  2. time of next service completion for S1 = 1.76284.
