Discrimination in Railway Facilities

Locating mobile facilities in railway construction management ¬リニ

The location problem with mobile facilities is motivated by a real-life railway construction project. In railway construction, (im)mobile concrete batching facilities are located to build viaducts and tunnels on a line over a planning horizon. The problem is to determine the number and types of facilities to be located, to schedule the movement of mobile facilities, and to make concrete product...

Calculation of lateral velocity estimation and error discrimination for railway wheelset to avoid sliding

Lateral velocity has very backbone position in the railway vehicle wheelset dynamics as it usually becomes cause of derailment by sliding due to insufficient adhesion ratio. This impropriate balance is pretext owing to contamination and weather procures the disturbances. This perturbation makes hindrances in proper running of wheelset on track. To analyze the noise, Kalman filter is used based ...

Input third-degree price discrimination by congestible facilities

This paper studies third-degree price discrimination by transport facilities, such as airports and seaports, which sell access to the infrastructure as a necessary input for downstream production. These facilities are prone to congestion –which makes downstream markets interrelated– and their ownership structure is diverse, varying from public (domestic welfare maximizing) to private (profit ma...

Methods for Analysis of Odor-related Volatile Compounds in Railway Facilities

Attention to hygienic environments in public spaces is increasing, and we believe that it is important to understand and evaluate this aspect of railways in their role as a means of public transportation. Previously, we carried out investigation regarding types and amounts of airborne microbes (mainly fungi) floating in station precincts as well as evaluating railway passengers’ perception of h...
