Description

The railway signaling system plays an important role to achieve the safety and the reliability. The income of the railway company is assumed to decrease by the low birthrate and aging. So the railway company is required a reduction of life cycle cost of equipment. In this paper, we propose a new life cycle cost model that considered “the economic loss cost of the passengers who have encountered with the equipment fault” in a life cycle cost model. And we performed various case studies that considered economic loss cost, and confirmed that reduction of the life cycle cost was possible.
