Life cycle cost model for evaluating RAMS requirements for rolling stocks

초록

We need to consider not only service quality but also the purchase and maintenance cost when setting the RAMS requirements for rolling stock. This article suggests one indicator to evaluate the effectiveness of the RAMS requirements which is LCC (Life cycle cost). A new LCC model is suggested which is based on LCC elements affected by RAMS requirements. Acquisition cost, maintenance cost and hazard cost are considered as LCC elements. Numerical studies are performed to investigate the effect of RAMS parameters on LCC.
