A cafeteria serving line has a coffee urn from which customers serve themselves. Arrivals at the urn follow a Poisson distribution at the rate of 4.0 per minute. In serving themselves, customers take about 12 seconds, exponentially distributed. a. How many customers would you expect to see on the average at the coffee urn? (Do not round intermediate calculations. Round your answer to 2 decimal places.) Average no of customers b. How long would you expect it to take...
Problem 10-10 A cafeteria serving line has a coffee urn from which customers serve themselves. Arrivals at the urn follow a Poisson distribution at the rate of 4.0 per minute. In serving themselves, customers take about 8 seconds, exponentially distributed. a. How many customers would you expect to see on the average at the coffee urn? (Do not round intermediate calculations. Round your answer to 2 decimal places.) Average no of customers ____ b. How long would you expect it...
Customers enter the camera department of a store at an average rate of five per hour. The department is staffed by one employee, who takes an average of 8.0 minutes to serve each arrival. Assume this is a simple Poisson arrival, exponentially distributed service time situation. (Use the Excel spreadsheet Queue Models.) a-1. As a casual observer, how many people would you expect to see in the camera department (excluding the clerk)? (Round your answer to 2 decimal places.) a-2....
Some restaurants have an average of six men per hour, an average of 12 women per hour, and 12 children per hour. What is the probability of at least two customers coming in five minutes, regardless of age or sex? What are the basic assumptions for calculating this probability?
On a normal weekday, a local Philz Coffee Shop has 12 customers waiting in line on average. If it takes 13 minutes for a customer to get his/her coffee served on average, the coffee shop is serving customers per hour. Type in the answer rounded up to 2-decimal places. Throughput Time = Average WIP / Throughput Rate
A vending machine dispenses hot chocolate or coffee. Service time is 30 seconds per cup and is constant. Customers arrive at a mean rate of 61 per hour, and this rate is Poisson-distributed. a. Determine the average number of customers waiting in line. (Round your answer to 2 decimal places.) Average number of customer b. Determine the average time customers spend in the system. (Do not round intermediate calculations. Round your answer to 2 decimal places.) Average time minutes ...
The Zagat Restaurant Survey provides food, decor, and service ratings for some of the top restaurants across the United States. For 27 restaurants located in a certain city, the average price of a dinner, including one drink and tip, was $48.60. You are leaving on a business trip to this city and will eat dinner at three of these restaurants. Your company will reimburse you for a maximum of $50 per dinner. Business associates familiar with these restaurants have told...
The number of customers that enter a bank follows a Poisson distribution with an average of 30 customers per hour. What is the probability that exactly 3 customers would arrive during a 12 minute period?
Problem 15-9 (Algorithmic) Marty's Barber Shop has one barber. Customers have an arrival rate of 2.3 customers per hour, and haircuts are given with a service rate of 4 per hour. Use the Poisson arrivals and exponential service times model to answer the following questions: What is the probability that no units are in the system? If required, round your answer to four decimal places. P0 = What is the probability that one customer is receiving a haircut and no...
Assume the number of cars that drive through the Mooncents Coffee Shop drive-through window follows a Poisson probability process with a known average of 6 cars per hour (per 60 minutes). a. Find the expected number of cars driving though in a 23 minutes period. (Round your final answer to 1 decimal place.) Expected number of cars b. Find the probability of at least 2 cars driving through in a given 23 minutes period. (Round your answer to 4...
