S7.20. An army division in Iraq has five troop encampments in thedesert, and the division leaders want to determine the best locationfor a supply depot to serve the camps. The (x, y) coordinates (in miles)of the camps, A, B, C, D, and E, and the daily amount of supplies (intons) required at each camp are as follows:S.CCoordinatesCampyDaily tonnage (1000s)11012085703001105203507530045060E400600100m uoya. Determine the best site for the supply depot using the cen-ter-of-gravity technique.b. Suppose the division commanders are limited to three possi-ble sites for the supply depot because of airfield locations andenemy troop concentrations. The coordinates (in miles) of thesethree potential sites are site 1 (400, 250), site 2 (100, 200), and site3 (200, 500). Using the load-distance technique, determine thebest site for the supply depot.antsA,B.

Wiebe Trucking, Inc., is planning a new warehouse to serve the western United States. Denver, Santa Fe, and Salt Lake City are under consideration. For each location, annual fixed costs (rent, equipment, and insurance) and average variable costs per shipment (labor, transportation, and utilities) are listed in the following table. Sales projections range from 550,000 to 600,000 shipments per year. Location Annual fixed cost Variable Costs per Shipment Denver $5,000,000 $4.65 Santa Fe $4,200,000 $6.25 Salt Lake City $3,500,000 $7.25 a.

7. The BD restaurant chain purchases materials from four different food suppliers. The company wants to construct a new central distribution center to process and package the materials before shipping them to their various restaurants. The suppliers transport items in 40-foot truck trailers, each with a capacity of 38,000 lbs. The locations of the four suppliers and the annual number of trailer loads that will be transported to the distribution center are shown in the following table (distance in miles). Using the center-of-gravity method, determine a possible location for the distribution center.

Then, the best site for Daniel Tracy will be C with a total weighted score of 197. (Enter your response as an…
Task 1: An oil refining company ships the following gasoline volumes from its refining plant in Long beach to its major distributors: Coordinates (x, y) 400, 150 450, 350 350, 400 25, 450 Distributor Gallons (in millions) Anaheim 150 LaHabra 350 Glendale 250 Thousand Oaks 450 The location coordinates of the refining plant in Long Beach are: (325, 75). Under a new proposed distribution setting, the company wants to setup an intermediate holding facility, such that gasoline will first get transported to this holding facility, and then, from there, to the distributors. What will be the ideal location (coordinates) for the intermediate holding facility? (Round to 2 decimal places.)
