Solve the following problem using excel and evaluate the result. A Refrigerator Manufacturing Company (RMC) is considering expansion and evaluating where to locate a new manufacturing plant. The RMC will handle 900 items of its production to a main customer at coordinates (5,10) and 600 items to a second major customer at (13,10). Six plant locations are under consideration: A (16,13) B (12,18) C (15,21) D (13,22) E (16,23) F(18,14) If we use rectilinear distance, which location will minimize total load-distance for RMC? Moreover, on the second sheet of excel file (in same file), add three more plant locations G(15,17), H(24,18), and I(13,22). Evaluate and determine best location again.
