The development of an FMEA methodology for rolling stock remanufacture and refurbishment

摘要

This paper discusses the remanufacture of equipment within the railway industry and definitions are given. A systematic method to the planning and execution of equipment remanufacture is proposed based on a Failure Mode and Effect Analysis (FMEA), which enables critical systems to be identified, robust remanufacturing processes established and appropriate NDT methods selected. For optimal decision making in regard to remanufacture, cost has to be considered. An iterative approach is suggested which will link cost models, particularly life cycle costing (LCC) with the risk assessment from the FMEA. This will allow optimal strategies to be evaluated in terms of the market demands. A case study of an air-conditioning unit from a DMU is presented to illustrate the initial section of the method.
