This study is a first approach to the Preliminary Engineering Analysis of a Light Rail Transit (LRT) System. The study is divided into four interrelated parts. The first one consists on a presentation of the RAM Discipline, by a development of its theoretical foundations and the four Key Performance Indicators used through all the study. The methodology employed during the analysis and actual methods used for RAM analysis are also described in this section. Then, it has been developed a Failure Mode and Effects Criticality Analysis (FMECA) with a subsequent Sensitive Analysis to ensure that the results are binary in terms of probability. With that, a consequent Fault Tree Analysis (FTA) has been carried out. After that, the third part of the study provides the LRT RAM Requirements Apportionment and last, but not least, Preventive/Corrective Actions have been proposed.
The TFG title mentioned consists on a RAM Study of a Light Rail Transit (LRT) System. Its aim lies in achieving a defined level of service in a given time, by demonstrating quantitatively and qualitatively the availability of the system. The Quality of the Service has to be guaranteed by the application of engineering concepts, methods, techniques and tools, such as ITEM Toolkit.
