3. A corporation has decided to produce three new products. Five branch plants now have excess product capacity. The unit manufacturing cost of the first product would be $31, $29, $32, $28, and $29, in plants 1, 2,3, 4, and 5, respectively. The unit manufacturing cost of the second product would be $45, $41, $46, $42, and $43 in Plants 1, 2, 3, 4, and 5, respectively. The unit manufacturing cost of the third product would be $38, $35, and $40 in Plants 1, 2, and 3, respectively, and Plants 4 and 5 do not have the capability for producing this product. Sales forecasts indicate that 600 1000, and 800 units of products 1, 2, and 3, respectively, should be produced per da Plants 1, 2, 3, 4, and 5 have the capacity to produce 400, 600, 400, 600, and 1000 units daily, respectively, regardless of the product or combinations of products involved Assume that any plant having the capability and capacity to produce them can produce any combination of the products in any quantity Management wishes to know how to allocate the new products to the plants to minimize the total manufacturing cost Formulate this problem as a transportation problem by constructing the appropriate cost and requirements table.
