1) choose a random integer between 1 and 4 to determine the minute at which the first customer arrives.

2) At the first customer’s arrival time:

Determine customer’s service time (random integer from 1 to 4);

Begin servicing the customer;

Schedule arrival time of next customer (random integer 1 to 4 added to the current time).

3) For each minute of the day;

If the next customer arrives,

Say so,

Enqueue the customer;

Schedule the arrival time of the next customer;

If service was completed for the last customer;

Say so

Dequeue next customer to be serviced

Determine customer’s service completion time( random integer from 1 to 4 added to the current time).

Now run your simulation for 720 minutes and answer each of the following:

a) What’s the maximum number of customers in the queue at any time?

b) What’s the longest wait any one customer experiences?

c) What happens if the arrival interval is changed from 1-4 minutes to 1-3 minutes?
