Whole Life-Cycle Cost Study Model of Urban Rail Transit

On the basis of whole life-cycle cost analysis theory, this article establishes the whole life-cycle cost analysis mathematical model for urban rail transit. Based on lots of investigation materials and through the method of statistical analysis, the cost components of urban rail transit was obtained, and this achievement has high reference value for the cities with new rail transit and the new rail transit engineering. This article selected the ventilation air-condition system as the object of whole life-cycle cost analysis and conducted numerical examples analysis. This is a beneficial attempt for the whole life-cycle cost theory utilized in urban rail transit cost analysis.
