EYDeluxe River Cruises operates a fleet of river vessels. The fleet has two types of vessels: a type A, x, vessei has 60 deluxe cabins and 160 standard cabins, whereas a type B vessel, y, has 80 deluxecabins and 120 standard cabins. Under a charter agreement with the Odyssey Travel Agency, Deluxe River Cruises is to provide Odyssey with a minimum of 360 deluxe and 680 standard cabins for their15-day cruise in May. It costs $58,000 to operate a type A vessel and $54,000 to operate a type B vessel for that period.(a) How many of each type of vessel should be used to keep the operating costs C to a minimum?The minimum is C =(b) Suppose C = cx + 54,000y. Find the range of values that the cost of operating a type A vessel, the coefficient c of x, can assume without changing the optimal solution.≤CM(c) Find the range of values that Requirement 1 for deluxe cabins can assume.

A bus system needs to be set up from Village of Westmont to Hinsdale (2.5 miles), then continues to Berwyn (8.5 miles), and finally terminates its run to Cicero (1 mile). The operating time is 55 minutes, the policy headway is 30 minutes, and the minimum terminal time is 19 minutes (including 6 minutes terminal time at each location of Clarendon Hills and Berwyn, and 7 minutes at Cicero). It has been established that the peak-hour demand is 500 passengers per hour and 50-seater buses are available, which can safely accommodate 25 standees. Assume the load factor is 0.8. Design the bus system
SkyChefs, Incorporated, prepares in-flight meals for a number of major airlines. One of the company's products is grilled salmon with new potatoes and mixed vegetables. During the most recent week, the company prepared 4,000 of these meals using 960 direct labor- hours. The company paid its direct labor workers a total of $19,200 for this work, or $20.00 per hour. According to the standard cost card for this meal, it should require 0.25 direct labor-hours at a cost of $19.75 per hour. Required: 1. What is the standard labor-hours allowed (SH) to prepare 4,000 meals? 2. What is the standard labor cost allowed (SH x SR) to prepare 4,000 meals? 3. What is the labor spending variance? 4. What is the labor rate variance and the labor efficiency variance?
Agan Interior Design provides home and office decorating assistance to its customers. In normal operation, an average of 2.4 customers arrive each hour. One design consultant is available to answer customer questions and make product recommendations. The consultant averages 10 minutes with each customer. Agan's management would like to evaluate two alternatives: 1. Use one consultant with an average service time of 7 minutes per customer. 2. Expand to two consultants, each of whom has an average service time of 10 minutes per customer. If the consultants are paid $17 per hour and the customer waiting time is valued at $28 per hour, should Agan expand to the two-consultant system? Explain. (Express the total cost per hour in dollars. Round your answers to the nearest cent.) The total service cost per hour, i.e. the time value of consultant and customer together, is $[ x for scenario 1, and $ for scenario 2. The business should implement the lower total cost scenario, which is scenario…
For his classes, Professor Wright gives three types of quizzes, objective, recall, and recall-plus. To keep his students on their toes, he has decided to give at least 20 quizzes next quarter. The three types, objective, recall, and recall-plus quizzes, require the students to spend, respectively, 10 minutes, 30 minutes, and 60 minutes for preparation, and Professor Wright would like them to spend at least 12 hours(720 minutes) preparing for these quizzes above and beyond the normal study time. An average score on an objective quiz is 5, on a recall type 6, and on a recall-plus 7, and Dr. Wright would like the students to score at least 130 points on all quizzes. It takes the professor one minute to grade an objective quiz, 2 minutes to grade a recall type quiz, and 3 minutes to grade a recall-plus quiz. How many of each type should he give in order to minimize his grading time?

An automobile company produces cars in Los Angeles and Detroit and has a warehouse in Atlanta.The company supplies cars to customers in Houston and Tampa. The costs of shipping a car betweenvarious points are listed in the table below, where a blank means that a shipment is not allowed. LosAngeles can produce up to 1100 cars, and Detroit can produce up to 2900 cars. Houston must receive2400 cars, and Tampa must receive 1500 cars. (Include your formulations to receive credit. Thinkcarefully about the transhipment locations.) (a) Determine how to minimize the cost of meeting demands in Houston and Tampa. (b) Modify the answer to part (a) if shipments between Los Angeles and Detroit are not allowed. (c) Modify the answer to part (a) if shipments between Houston and Tampa are allowed at a cost of$5 per car.
A famine relief effort is being mounted and there are three types of food bundles that can be flown out during each delivery. Bundle 1 has 4 kg. of flour, 4 kg. of sugar and 12 litres of water. Bundle 2 has 12 kg. of flour, 4 kg. of sugar and 4 litres of water and Bundle 3 has 8 kg. of flour, 8 kg. of sugar and 8 litres of water. The relief agency has 5200 kg. of flour, 3792 kg. of sugar and 6000 litres of water for each shipment. Bundle 1 can provide for 10 people between deliveries, Bundle 2 for 8 people and Bundle 3 for 11 people. How many bundles of each type should the relief agency send on each flight in order to maximize the number of people being fed. Do this problem by setting up a linear programming problem and determining the vertices of the feasibility set. Enter the number of bundles of types 1, 2, and 3 (in that order) into the answer box below, separated with commas.
