Suppose that there are 2 sources that generate waste and 3 disposal sites. The amount of waste generated at sourceAis 200 and at sourceBis 400.

  1. Suppose that there are 2 sources that generate waste and 3 disposal sites. The amount of waste generated at source A is 200 and at source B is 400. The capacity of disposal sites 1, 2 and 3 are 250, 150 and 100, respectively. The unit shipping costs from waste sourceA to disposal sites 1, 2 and 3 are 35, 15, and 20, respectively. The unit shipping costs from waste source B to disposal sites 1, 2 and 3 are 20, 5, and 15, respectively. Write the formulation for determining the optimal assignment that minimizes transportation costs.
