Research Field

Social Information Systems.

Research Overview

Studying information infrastructure systems and information control systems.

Research Subjects

  • 1. Information control system operation management.
  • 2. New social infrastructure technology.

Introduction:

We investigate decision making that uses information mathematical principle techniques and information technology for large-scale social infrastructure including water services, traffic, electric power, and information systems.

Flow time and volume in large-scale water distribution networks

Maximization of traveling points by electric vehicles

Trihalomethane (THM) formation is related to the time that chlorine used as a disinfectant in water purification plants is in contact with organic substances (THM precursors) in untreated water. We are developing a solution algorithm for analytically calculating water residence time in water purification plants, which determines the time that chlorine is in contact with organic matter, affecting THM formation.

We are investigating route optimization to maximize the number of points visited by an electric vehicle in a tour beginning and ending at the same point, considering the battery properties and capacity.
