[92] Optimal Location of Hierarchical Regional Centers
Analyzed by Simultaneous Optimization Model of Facility Location and Transportation Network Design
Keywords:facility location, inclusive hierarchical facilities, network design, urban structure, optimization
In this study, we construct a mathematical model that simultaneously minimizes the operating costs of regional centers and network, as well as the traveling cost of center users. In recent years, the spread of videoconferencing and related services enables people to receive higher level services at the lower-level center near their residences without going to the higher-level center. The model was used to calculate the optimal center locations and network structure in the case of a decrease of demand and an increase in the demand capture rate at the lower centers, and clarified that it is important to appropriately change the location and network structure according to the changes expected in the future, from the viewpoint of efficiency.
