Cooperation and competition to design a point-to-point airline network under regulation for a new entry
Autor: Jinha HIBINO, Shungo KOICHI, Takehiro FURUTA, Mihiro SASAKI
Publikováno v: Journal of Advanced Mechanical Design, Systems, and Manufacturing, Vol 16, Iss 4, Pp JAMDSM0044-JAMDSM0044 (2022)
In this paper, we propose a point-to-point airline network design model where a new company plans to enter a market to maximize its revenue under a regulation. The presented model prevents the entrant company from developing a route that may drastica

Railway flow interception location model: Model development and case study of Tokyo metropolitan railway network
Autor: Ken-ichi Tanaka, Takehiro Furuta, Shigeki Toriumi
Publikováno v: Operations Research Perspectives, Vol 6, Iss , Pp - (2019)
The flow interception location model (FILM) focuses on vehicular traffic in a road network and locates a fixed number of facilities so as to maximize the total flow that can be serviced at facilities along preplanned routes, such as a daily commute t

TDMA scheduling problem avoiding interference in multi-hop wireless sensor networks
Autor: Mihiro SASAKI, Takehiro FURUTA, Takamori UKAI, Fumio ISHIZAKI
Publikováno v: Journal of Advanced Mechanical Design, Systems, and Manufacturing, Vol 10, Iss 3, Pp JAMDSM0047-JAMDSM0047 (2016)
In this paper, we consider a multi-hop sensor network, where the network topology is a tree, TDMA (time division multiple access) is employed as medium access control, and all data generated at sensor nodes are delivered to a sink node (the base stat

Two Approaches to Cooperative Covering Location Problem and Their Application to Ambulance Deployment
Autor: Takehiro Furuta, Hozumi Morohosi
Publikováno v: Operations Research Proceedings ISBN: 9783319429014
OR
This study proposes two approximation methods to define the coverage probability in ambulance location problems based on the model of cooperative covering proposed by Berman et al. (IEE Trans. 40, 232–245, 2010, [1]) as an extension to classical co

MINISUM AND MINIMAX LOCATION MODELS FOR HELICOPTER EMERGENCY MEDICAL SERVICE SYSTEMS
Autor: Ken Ichi Tanaka, Takehiro Furuta
Publikováno v: Journal of the Operations Research Society of Japan. 56:221-242
This paper presents minisum and minimax location problems for helicopter emergency medical service (HEMS) systems. Given demand points (origins) and hospitals (destinations), the locations of rendezvous points and helicopter stations are selected to

A MATHEMATICAL PROGRAMMING APPROACH TO THE MULTI-ROUND TOPOLOGY CONSTRUCTION PROBLEM IN WIRELESS SENSOR NETWORKS
Autor: Atsuo Suzuki, Fumio Ishizaki, Takehiro Furuta, Mihiro Sasaki
Publikováno v: Journal of the Operations Research Society of Japan. 55:199-208
One of the important issues in wireless sensor networks is how to save power consumption and extend the network lifetime. For this purpose, various network topology construction algorithms have been studied. However, most of them are based on a metho
