Abstract: “In a large - scale high - rise building, elevator systems with multiple elevator cars supports m obility of users. Since current elevator controller system s o nly achieve user’s requirements as the existence of requests of mobility directions in each flo or, it is difficult for multiple elevator cars to stop at the same floor simultaneously even if there exist unevenly distributed requests in some specific flo ors. This results in low service ratio causing numbers of bumped passengers and in longer waiting time duration of the users. This pa per proposes a novel method for registrations of user’s requests through a smartphone application. Due to achievement of mo bili ty request of each user through his/her personal device, the elevator controller system acquires numbers and distribution of i ndividual mobility requests and detailed control of elevator cars including simultaneous stops of multiple elevator cars at th e same floor is realized. Simulation experiments show the proposed m”
