Question

At BCD car wash, when a customer arrives, he or she first checks in with a receptionist and then leaves the car to one of several car washers. While the customer is waiting for the car to be washed, he or she proceeds to pay at the cash register. After the payment, the customer returns to his/her car when it is done and then leaves. On average, reception takes 3 minutes. Car wash takes 5 minutes. Paying at the cash register takes 4 minutes. Returning to car and leaving requires 2 minutes. Currently, the car wash employs 1 receptionist, 2 cash registers and 3 car washers. What is the theoretical flow time (in minutes) of the process?

Answer 1

Answer:

10 minutes

Explanation:

Data provided in the question

Reception taking time = 3 minutes

Car wash taking time = 5 minutes

Paying the cash register taking time = 4 minutes

Returning to car and leaving taking time = 2 minutes

So, the theoretical flow time in minutes is

= Reception taking time + maximum time of car wash and paying the cash register + returning to car and leaving taking time

= 3 minutes + 5 minutes + 2 minutes

= 10 minutes
