The table below gives supply and demand of the revised textbook example for the Pear Disk Drive Corporation. (all numbers below are in thousands) Plant Production Warehouse Requirement Sunnyvale 60 Amarillo 100 Dublin 150 Teaneck 84 Bangkok 125 Chicago 82 Sioux Falls 69 The unit shipping cost from each plant to each warehouse is: TO Amarillo Teaneck Chicago Sioux falls FROM Sunnyvale 250 420 380 280 Dublin 1280 990 1440 1520 Bangkok 1550 1420 1660 1730 (a) Using the Greedy Heuristic method to minimize the shipping cost, fill in the table below with your results. (10 pts) (b) Let X denote the number of products shipped from plant i to warehouse (i - 1,2,3; J - 1,2,3,4; assign indices to plants / warehouses in the order as they appear in the first table). If a linear programming method is used to find out the optimal shipping arrangements, write out the two linear constraints that are related with X24 (i.e., product amount shipped from Dublin to Sioux Falls). (5 pts) (c) If the demand in Teaneck is increased to 94 (all other remain unchanged), we will have an unbalanced problem. In this case, write out again the two linear constraints that are related with X24.
