Example in Section 10.1 The transportation

Example in Section 10.1 The transportation

Example in Section 10.1 The transportation

Example in Section 10.1 The transportation problem is balanced because the total supply = total demand Total supply = 5000 + 6000 + 2500 = 13500 units Total demand = 6000 + 4000 + 2000 + 1500 = 13500 units Decision variables: Xij = number of units shipped from plant i to distribution center i where i = 1, 2, and 3 and j = 1, 2, 3, and 4. Following Figure 10.1, plant 1 is located in Cleveland, plant 2 is located in Bedford, and plant 3 is located in York. Similarly, distribution center 1 is located in Boston, etc. There are 12 (or 3*4) decision variables because there are 12 distribution routes (arcs). Objective function: Minimize the total transportation cost where the total transportation cost = (3)X11 + (2)x12 + .....+ (4)X33+ (5)X34 Supply constraints: The total number of units sent from Cleveland plant must be less than or equal to the plant capacity in Cleveland. Thus, X11+X12 + X13 + X14 = 0; i = 1, 2, 3; j = 1, 2, 3, 4
