| Abstract | |
| In this paper, we have introduced a practical problem for determining the purchasing quantities and transportation decision simultaneously. We have formulated the problem as a mathematical programming model. Since the objective function of the problem is not convex and has more than one peak, the classical optimisation techniques based packages fail to find the optimal solution for the developed model. We have developed an Evolutionary Algorithm based simple solution approaches for the model. Our approach provides solutions better than the best known methods in the literature and similar to the explicit enumeration method. The computational experiences are reported. | |
