Q. The neighborhood kids set up an outdoor lemonade stand in Maryland in June. They find that their average customer arrival rate is 14 per hour even though they are capable of serving 1 customer every 2 minutes. What is the average time a customer spends waiting in line to be served? Please provide your answer in seconds. What is the probability that the kids will have MORE THAN 2 customers in the queueing system?
Please answer using stochastic
operations principles
Cars arrive at a rate of 10 per hour in a single-server drive-in restaurant. Assume that the teller serves vehicles with a rate exponentially distributed with a mean of 4 minutes per car (ie, a rate of 1 car every 4 minutes). Answer the following questions: (a) What is the probability that the teller is idle? (b) What is the average number of cars waiting in line for the teller? (A car that is...
Assume that for a gas and car wash station one car can be serviced at a time. The arrivals follow a Poisson probability distribution, with an arrival rate of 1 car every 10 minutes and the service times follow an exponential probability distribution, with a service rate of 8 cars per hour. What is the probability that the station will be idle? What is the average number of cars that will be waiting for service? What is the average time...
In Java, complete the following: During the lunch hour, the ATM machine in a large office complex is in heavy demand. Customers complain that the waiting time is much too long. The local bank considering the addition of a second ATM machine. But first, the bank needs a few statistics to justify the cost of adding a second ATM machine. Using a Queue, simulate a waiting line at the ATM machine for a period of one hour. Make the following...
56) One employee is in charge of the following activities at a refreshment stand: Activity Greet customer Take order Process order Print receipt Activity Time per Customer 5 seconds 25 seconds 1.5 minutes 30 seconds If demand rate is 20 customers per hour, what are the flow rate (in customers per hour), utilization, and cycle time (in minutes per customer)? A) 20, 0.83, 0.05 B) 24, 1, 0.04 c)20,0.83, 3 D) 24, 1,25 57) Patients are arriving at a clinic...
A local Walmart is adopting its new Corporate customer drive-through order pick-up program. Based on its serving region and demographics (households with smart phones, internet access, on-line shopping habits, etc.), it estimates that once launched, customers will arrive randomly according to a Poisson process with a mean hourly arrival rate of 100 cars per hour. This randomness will occur despite the fact that customers schedule a time window for their arrival. During their order pick up, some customers trust that...
1. A new shopping mall is considering setting up a car wash manned by six employees. From past data, Regal Car Wash estimates that dirty cars arrive at the rate of 10 per hour all day Saturday. With a crew working the wash line, Regal figures that cars can be cleaned at the rate of one every 5 minutes. One car at a time is cleaned in this example of a single-channel waiting line. It is assumed that arrivals are...
QUESTION 1 Customers arrive at a hair salon according to a Poisson process with an average of 16 customers per hour. Which of the following is most likely true, based on this information: a. The hair salon serves customers on a walk-in basis (rather than by appointment times) b. If 10 customers arrive in the first hour, it is likely that 22 customers will arrive in the next hour. c. If the salon can serve an average of 20 customers...

Problem 1 REGIONAL AIRLINES Regional Airlines is establishing a new telephone system for handling flight reservations. During the 10:00 A.M. to 11:00 A.M. time period, calls to the reservation agent occur ran- domly at an average of one call every 3.75 minutes. Historical service time data show that a reservation agent spends an average of 3 minutes with each customer. The waiting line model assumptions of Poisson arrivals and exponential service times appear reasonable for the telephone reservation system. Regional...
