- Abstract
- Under agile and global manufacturing environment, importance of logistics as a core of supply chain management has been acknowledged increasingly. In this study, we provide a practical hybrid method for a hierarchical logistic network optimization belonging to a tactical level. Since the problem is composed of different kinds of NP-hard combinatorial optimization problems, its rigid solution is almost impossible for real world problems. Hence, to cope with the problem in practice, we have developed a three-level method in terms of the modified insertion method for VRP with time windows. It is deployed based on Ton-Kilo (bilinear of load (ton) and distance (km)) evaluation instead of the conventional Kilo base (distance only). It also includes a new mechanism that enables us to engage in multi-objective analysis between economy and quality of delivery. Validity of the developed method is examined through numerical experiments.
