Solution Method for Multi-Product Two-Stage Logistics Network with Constraints on Delivery Route

The logistics network design is one of the important phases of Supply Chain Management (SCM) and it is a problem that should be optimized for long-term promotion of efficiency of the whole supply chain. Usually a plant produces different types of products. Even if it is a factory of the same company, delivery differs according to the kind of produced product. The restrictions which this model has are deeply concerned with TP in the real world. In this paper, we consider the logistics network design problems with multiple products and constraints for delivery course. To solve the problem, we used a hybrid priority-based genetic algorithm (h-priGA), and we tried comparison experiments with priority-based genetic algorithm (priGA) and h-priGA, and show the effectiveness of h-priGA.
