Concept explainers
Suppose that a new company has five employees: Zamora. Agraharam. Smith, Chou, and Macintyre. Each employee will assume one of six responsibilities: planning, publicity, sales, marketing, development, and industry relations. Each employee is capable of doing one or more of these jobs: Zamora could do planning, sales, marketing, or industry relations; Agraharam could do planning or development; Smith could do publicity, sales, or industry relations; Chou could do planning, sales, or industry relations; and Macintyre could do planning, publicity, sales, or industry relations.
a) Model the capabilities of these employees using a bipartite graph.
b) Find an assignment of responsibilities such that each employee is assigned one responsibility.
c) Is the matching of responsibilities you found in part (b) a complete matching? Is it a maximum matching?

- MISSION IMPOSSIBLE 1. 2. There are five hunting cabins on a lake. Each cabin is a different color, and is inhabited by a man of a different nationality, each drinking a different kind of soft drink, firing a different kind of shotgun shell and shooting a different duck. The cabins are in the following order from left to right: yellow, blue, red, brown and green. 3. The Englishman lives in the red cabin. 4. The Canadian shoots only Bluebill ducks. 5. Pepsi is drink of choice in the green cabin. 6. The American drinks Coke. 7. The hunter who uses Winchester shells shoots Mallard ducks. 8. Remington shells are shot by the man in the yellow cabin. 9. The drink of choice in the middle cabin is Dr. Pepper. 10. The Norwegian lives in the first cabin on the left. 11. The man who buys Federal shells lives in the cabin next to the cabin of the man who shoots Redhead ducks. 12. Remington shells are used in the cabin next to the cabin where the man lives who shoots Canvasback ducks. The Problem:…arrow_forwardThe Phony TV company makes two different types of television sets, OLED and LED, which are assembled by two different assembly lines. When Line One operates it assembles 30 units of the OLED model and 50 units of the LED model per hour. Line Two assembles 40 units of the OLED model and 40 units of the LED model per hour. Let x be the number of hours that Line One operates and y the number of hours Line Two operates. Phony needs to produce at least 3000 units of the OLED model and 4000 units of the LED model to fill an order. (a) Write down the inequalities that describe the assembly constraints. (b) Graph the feasible region determined by these constraints.arrow_forwardOne of your duties is the selection and disposal of boxes of obsolete files.

- A manufacturer of table saws has three models-Deluxe, Premium, and Ultimate-that must be painted, assembled, and packaged for shipping. The table gives the number of hours required for each of these operations for each type of table saw. If the manufacturer has 104.1 hours available for painting, 360 hours for assembling, and 123.2 hours for packaging, how many of each type of saw can be produced each day? Deluxe 1.2 Painting Assembling 3 Packaging 0.4 Premium Ultimate 2 2.3 7 8 0.9 3 The manufacturer can produce deluxe saws, premium saws, and ultimate saws.arrow_forwardA manufacturer of downhill and cross-country skis reports that manufacturing time is 1 hours and 4 hours, respectively, per ski and that finishing time is 3 hours for each downhill and 4 hours for each cross-crountry ski. There are only 16 hours per week available for the manufacturing process and 24 hours for the finishing process. The average profit is $62 for downhill ski and $92 for cross-country ski. The manufacturer wants to know how many of each type of ski should be made to maximize the weekly profit. Corner points of the feasible region: If there is more than one corner point, type the points separated by a comma (i.e. (1,2).(3,4)). Maximum profit is: $ when and downhill skis cross country skis are produced.arrow_forwardA 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.

The bank has up to P80,000,000 available to open new branches, and has decided to limit the new branches to a maximum of 20 and to hire at most 120 employees. How many branches of each type should the bank open in order to maximize the average daily revenue? REQUIREMENTS: 1. Formulate the LP Model; 2. Identify the decision variables used in the model; and 3. Determine the optimal solution.arrow_forward
