2.) Customers arrive at a candy shop every 8 minutes on average. What is the arrival rate? (Give the number only.)

3.) In a single-server queuing system, 10 customers arrive per hour, and 20 customers are served per hour. What is the arrival rate?

Homework Answers

Answer #1

1,) 12 customers/ hour

In this question, service rate is asked , in order to find it in hours (specifically asked) we will simply divide 60 by 5 minutes which is nothing but conversion.

service rate = 60/5 =12 customers/hour

which means in one hour 12 customers took service.

2.) 7 customers/ hour (approx.)

In this question, arrival rate is asked , in order to find it in hours (specifically asked) we will simply divide 60 by 8 minutes which is nothing but conversion.

service rate = 60/8 =7.5 customers/hour , we can not quantify human beings in fraction therefore here we will take 7 or 8.

which means in one hour 7 0r 8 customers arrive..

likewise in 3.)

3.) 6 customers / hour

A hamburger shop has three competitors. Since people do not like to wait in long lines for hamburger, the arrival rate to the shop depends on the number of people in the shop. While n <= 4 customers are present in the shop, customers arrive at a rate of (20-5n) customers per hour. If more than 4 people are in the shop, the arrival rate is zero. For each customer, revenues less raw material costs are 50 cent. Each server...

A fast-food franchise is considering operating a drive-up window food-service operation. Assume that customer arrivals follow a Poisson probability distribution, with an arrival rate of 24 cars per hour, and that service times follow an exponential probability distribution. Arriving customers place orders at an intercom station at the back of the parking lot and then drive to the service window to pay for and receive their orders. The following three service alternatives are being considered: System A: A single-server operation...

During lunch hour, customers arrive at a fast-food restaurant at the rate of 120 customers per hour. The restaurant has one line, with three workers taking food orders at independent service stations. Each worker takes an exponentially distributed amount of time–on average 1 minute–to service a customer. Let Xt denote the number of customers in the restaurant (in line and being serviced) at time t. The process (Xt)t≥0 is a continuous-time Markov chain. Exhibit the generator matrix.

Customers arrive at a two-server system according to a Poisson process having rate λ = 5. An arrival finding server 1 free will begin service with that server. An arrival finding server 1 busy and server 2 free will enter service with server 2. An arrival finding both servers busy goes away. Once a customer is served by either server, he departs the system. The service times at server i are exponential with rates µi, where µ1 = 4, µ2...
