Facility location model considering various behavior of users in time–space plane

In this paper, we discuss facility location considering various behavior of users in time and space plane using a model. First, we exhibit a location model in time–space plane. Second, we compare three location patterns of facilities in time–space plane: (1) grid; (2) random; (3) (t,m,s)-net, based on average traveling, waiting cost of users and covering percentage of services. Then, we show that (t,m,s)-net, which is a regularly scattered pattern in time–space plane, is the best location among the three patterns. Finally, we apply the model to the library and book mobile service in Kobe city.
