| Research Abstract |
1. The recommendation of environmentally-friendly business logistics system models
We surveyed current actions of environmentally-friendly business logistics system models in several Japanese logistics companies, and recommend environmentally-friendly business logistics system models
2. The development of approximate solution methods for the supply chain network design problem with arc capacity constraints
We developed the fastest approximate solution method for the network design problem with arc capacity constraints. The strong disaggregated forcing constraints are used for our formulation and the column generation method and the capacity scaling method are combined for our method. We show that our approximate solution method is the best method among other developed approximate methods.
3. The development of an approximate solution method for the supply chain network design problem with real transportation costs
We developed a fast approximate solution method for the network design proble

m with real transportation costs, which have piecewise linear functions. These piecewise linear functions correspond to the cost functions of door-to-door parcel, Less-than-Truck-Load and Truck-Load services. We show that our approximate solution method is better than other approximate methods.
4. The development of integrated geographical information systems for the vehicle routing / facility supply chain network design models
We developed the analyzing systems for the vehicle routing / facility network design models using annealing or dual ascent methods. By linking this analyzing system and geographical information systems, we developed the integrated geographical information systems for the vehicle routing / facility network design models.
5. The development of a product-to-plant allocation/reallocation model and its approximate solution method
For a corporate realignment of a Japanese company, we developed a large scale product-to-plant allocation/reallocation model to reduce transportation costs, and its approximate solution method by a tabu search method. Less
