Outline Activities
Most decision problems in the real world require multi-stage decisions, where successive decisions need to be made while taking into account changes in the situation that have been caused by previous decisions. For instance, a baseball team manager must give appropriate instructions to players while considering how the game will proceed as well as other possible uncertainties. I have been researching the theory and application of dynamic programming, which is an optimization method to efficiently solve these kinds of problems.
I am also interested in solving actual problems in society, and have carried out collaborative researches on Rich Vehicle Routing Problems with companies. The Vehicle Routing Problem (VRP) is a collective term for problems that design optimal delivery or collection routes from one or several depot(s) to a number of geographically scattered customers. Examples include the delivery of products to retail stores, or determining the paths that garbage trucks follow. As a practical application, I am working on developing a solver that provides a schedule for restoration crews to restore as soon as possible lifeline networks that are disrupted during a disaster.

Social
Professional and Outreach Activities
I am engaged in research on social mathematics, which uses mathematical techniques to design fair and highly convincing systems and measures to address social issues. My co-researchers and I have developed technology in collaboration with real world sites of social issues such as (a) efforts to improve passenger satisfaction at Fukuoka Airport, (b) system design for Japanese nursery school matching with siblings, (c) disaster restoration scheduling for lifeline networks, (d) optimization of the pallet sharing system as a logistics infrastructure, (e) shipper collaboration matching system in logistics..
