Let us presume that a product is made at two of our factories which we wish to ship to three of our warehouses. We produce 18 at factory A and 22 at factory B; we want 10 in warehouse 1, 20 in warehouse 2, and 10 in warehouse 3. Per unit transportation costs are A to 1, $4; A to 2, $2; A to 3, $3; B to 1, $3; B to 2, $2; B to 3, $1. Construct the appropriate costs and requirements tables to indicates the (a) (b) Solve the initial problem using Northwest Corner Approach. above transportation problem. (c) Calculate the initial solution using VAM method.
