The average flow time in the registration process of a busy motor vehicles office facing a variable customer arrival rate = 15 min/customer. Therefore, the average process flow rate would be equal to 4 customers/hour. Is that likely?
a. There's a 50/50 chance that the average process flow rate would be equal to, or not equal to, 4 customers/hour
b. Yes, but only if a maximum of 2 customers are allowed to be in the process at a time.
c. Yes, but only if they are served one at a time, that is, the next customer cannot enter the process until the customer currently in the process has exited the process.
d. likely, as long as there are multiple customers in the process at a time.
