| Research Abstract |
This research presents a monitoring and locational decision support system for retail activity. This system uses point-based customer densities as a set of data instead of area-based densities which have been used in most of the previous studies. Bicubic spline gridding and interpolation methods are applied to convert sample data to grid data and grid data to grid data, respectively. Retail trade areas are represented as a 3D surface in color-graphics to monitor the small changes. This system can also search for an optimal loca-tion for an intended store and assess its spatial impacts upon the existing stores using a spatial interaction model with bicubic splines.
