| Research Abstract |
To construct a logistics system based on multi-scale IT service, a method is proposed by fusing with fuzzy theory, decision making theory, and computational intelligence. Specifically, at first the concept of fuzzy neighborhood degree is created to improve the computing cost. By using a small size data of traveling-salesman problem (TSP), appropriate values of fuzzy neighborhood degree and some parameters changing for optimization algorithms are evaluated. Then the validity of the optimization algorithm is confirmed for large-scale data in TSP, and what could be carried out in realistic calculation time is investigated even if the scale becomes big. Furthermore, the proposed method is tested by using real-world data from both oil industry and convenience stores. The results are also presented in international conferences and are published in journal article magazines.
