| Research Abstract |
For discrete optimization problem, appearing in a variety of applications, it is hard to obtain an optimum solution efficiently in many cases. The aim of this research is to develop high-accuracy information-rich inventory management systems by using the theory of discrete convex analysis. Demonstration software for inventory system and discrete convex solvers are released. Also, this research revealed the relationship between convex extensibility and discrete Hessian matrices, which was not fully understood in general and some vague or imprecise statements had been made in the literature.
