Outline of Final Research Achievements |
We proposed dynamic facility location models that seek locations and opening hours of multiple facilities so as to maximize the volumes of commuter flows that can be accessible to facility services, and applied the models to Tokyo metropolitan railway network using commuter flow data. Concretely, we constructed the following models: (1) a model where multiple coverage levels are considered depending on the arrival time to a destination, (2) a model in which there is a minimum required time for commuters to enjoy the service, and (3) a model where opening hours of facilities are decision variables rather than a fixed constant. In addition, we focused various situations where the temporal dimension is a critical factor, and constructed mathematical models to evaluate the effects of shuttle bus system on visitors' traffic flow to the Tokyo Bay zone during the 2020 Tokyo Olympics, and problems for designing network infrastructures by considering the time horizon.
