| Abstract: | A dynamic programming model was developed to design multi-stage logistics networks using a genetic algorithm GA. This article describes the structural model, the decision-making methods, and the transport planning methods. The results show that transport planning provides a flexible, effective method to design small logistics networks. The combined genetic algorithm improves the accuracy and efficiency for large networks. Therefore, dynamic programming can be used to design multi-stage logistics networks. The paper also presents a nonlinear expression for the storage and transport costs for optimizing the logistics economics which is successfully applied to a multi-stage logistics network design. |
| Keywords: | dynamic programming logistics networks logistics expense genetic algorithms |
