Reliability modeling for automatic operation mode of FSWO&FSWB system

This paper applies FMEA and FTA approach which has been proved to be acceptable and widely applied in many applications of modeling and methods supporting the production system and the safety and/or maintenance manager to identify how subsystems and components could fail and what are the corresponding effects on the whole system, and to quantify the reliability parameters for complex systems. A case study represents that the automatic operation mode from the primary fuel switch to secondary fuel called FSWO (Fuel Switch Over) procedure, which is the process of switching fuels from natural gas to oil fuel. For FSWB (Fuel Switch Back), this is process of switching from oil fuel to natural gas. The numerical illustrations and results substantiate that the model approach capable of pointing out and quantifying the importance of each component in the system.
