Effective Reliability, Availability, Maintainability (RAM) and Safety (S), Principles and Guidelines for Large Subsurface Metro and Main Line Projects

摘要

This paper offers support and guidance on a major infrastructure subsurface railway project, to select and undertake an effective reliability, availability and maintainability and safety (RAMS) strategy. RAMS which forms part of systems engineering is an essential discipline and integrated in most railway undertakings. How projects choose to undertake this discipline is subjective, and can be different from project to project. The principle of the paper covers Crossrail methods primarily in the central area of the project. The paper is intended for railway operators (RO) and delivery organisation (DO) which includes the supply chain and RAMS practitioners of such work.
