System Reliability Modelling
A system is a collection of subsystems, assemblies and/or components arranged in a specific design in order to achieve desired functions with acceptable performance and reliability. The types of components, their quantities, their qualities and the manner in which they are arranged within the system have a direct effect on the system's reliability. Therefore, in addition to the reliability of the components, the relationship between these components is also considered and decisions as to the choice of components can be made to improve or optimize the overall system reliability, maintainability and/or availability. This reliability relationship is usually expressed using logic diagrams, such as reliability block diagrams (RBDs) and/or fault trees.
Consulting
Supporting both product design and asset management functions, our Engineers develop and analyse system Reliability Block Diagrams and Fault Trees, usually as part of a Reliability project. These models can be made-up from a variety of sources of data from standards-based libraries, to real-world test/field data or from Supplier’s product technical specification data.
Using exact computations or discrete event simulation, our Engineers use ReliaSoft’s BlockSim software to undertake a wide variety of analyses for both repairable and non-repairable systems. This includes reliability analysis, reliability optimization, and sensitivity studies, exploring the effect of redundancy on improved reliability against increased cost.
