A self-service car wash has 3 individual car wash stalls. Customers wait in a single line before choosing the next available stall. 33 customers enter the car wash per hour and it take 5 minutes for each customer to wash their car. Customer arrivals and service times follow an exponential distribution. What type of queuing model is this process?

single-channel, multi -phase

Step-by-step explanation:

The concept known as '' Queuing'' is not only important in the mathematical aspect alone but it is also useful in economic matters as signifies the abundance of resources that is when we have queues it means the reason for it is that the available resources is not enough.

From the question above we have that there are 3 individual car wash stalls, it is also given that the customers wait in a single line before choosing the next available stall. This means that there is only a single-channel.

Then, we have that from the single line initially, the queues then moves to multi -phase that is to  3 individual car wash stalls.
