RAM refers to the reliability (The probability that an item will perform a required function for a stated period of time),availability(The proportion of time that an item is capable of operating to specification within a large time interval),maintanability(The probability that a failed product will be restored to operational effectiveness within a given period of time when the repair action is performed in accordance with prescribed procedures).
Intellex Consulting Services (UK) Ltd ensures that all RAM activities are strictly practiced as per the CENELEC standards to ensure world-class quality .
Objective of RAM Engineering
To ensure that the assets delivered into the railway do perform as designed reliably which ensure safety to passengers/staff as well as provide economical returns for the investment.The main objective of RAM is to reduce the overall lifecycle cost(that includes maintenance cost,operation cost,production cost etc.) and increase the system productivity.
Intellex provide a web-based tool called Asset Optima-"Project FRACAS" to support RAMS demonstration during Defect liability period -Post commissioning of a project.
Asset Optima identify and resolve systematic failures as well as mitigate wear-in failures which enables an accelerated reliability growth of the delivered system to achieve steady state RAMS performance complying to the RAMS targets.
Asset Optima enterprise version (under development) would support reliability Centre Maintenance activities to maximise design life of the assets minimising whole life costs.
System reliability depends on avoidance of single point failures by redundant configuration of assets, asset population, asset reliability, low common cause failures and software reliability.
The RAM process includes performing RAM analysis of design and production of RAM deliverables in accordance with EN50126 during the design phase, Reliability Growth testing and trials supported by a robust failure root cause analysis and corrective action process called FRACAS (Failure Reporting Analysis and Corrective Action System)
