A chain of home health care firms in Louisiana needs to locate a central office from which to conduct internal auditsand other periodic reviews of its facilities. These facilities are scattered throughout the state, as detailed in thefollowing table. Each site, except for Houma, will be visited three times each year by a team of workers, who will drivefrom the central office to the site. Houma will be visited five times a year.CityCovingtonDonaldsonvilleX=HoumaMonroeNatchitochesNew IberiaMap CoordinatesX9.47.17.65.22.85.3Y3.22.5OpelousasRustonFor the location of the new central office, the coordinates should be near:5.23.61.78.16.82.13.38.5y=c.)

The Toys-R-4-U Company has developed two new toys for possible inclusion in its productline for the upcoming Christmas season. Setting up the production facilities to beginproduction would cost $50,000 for toy 1 and $80,000 for toy 2. Once these costs arecovered, the toys would generate a unit profit of $10 for toy 1 and $15 for toy 2. Thecompany has two factories that are capable of producing these toys. However, to avoiddoubling the start-up costs, just one factory would be used, where the choice would bebased on maximizing profit. For administrative reasons, the same factory would be usedfor both new toys if both are produced. Toy 1 can be produced at the rate of 50 per hourin factory 1 and 40 per hour in factory 2. Toy 2 can be produced at the rate of 40 perhour in factory 1 and 25 per hour in factory 2. Factories 1 and 2, respectively, have500 hours and 700 hours of production time available before Christmas that could beused to produce these toys. It is not known whether these…
Mick Karra is the manager of MCZ Drilling products which produces a variety of especially valves for oil field equipment. Recent activity in the oil fields has cause demand to increase drastically, and a decision has been made to open a new manufacturing facility. Three locations are being considered, and the size of the facility would not be the same in each location Thus, overtime might be necessary at times. The folowing table gives the total monthly cost (in 1000s) for each possible location under each demand posibility. The probabilities for the demand levels have been determined to be 20% for low demand, 30% for medium demand, and 50% for high demand Demand is Low Demand is medium Demand is High Ardmore, OK 85 110 150 Sweetwater, TX 90 100 120 Lake Charles, LA 110 120 130 (a) Which location would be selected based on the optimistic criterion?
