Sensitivity Analysis of Bridge Structure Systems’ Reliability

摘要

The sensors used in vehicle can be modelled as Bridge Structure Systems (BSS) which are System with Complex Interconnections (SwCI). Reliability of these systems cannot be simplified to single equivalent components or blocks by a combination of parallel and series reductions. Therefore Reliability Block Diagram (RBD) and Fault Tree Analysis (FTA) methods cannot be applied to determine reliability of the SwCI. The aims of this paper are to apply the True Table Method (TTM) and Linear Sensitivity Model of System Reliability (LSMoSR) to determine reliabilities of Bridge Structure System and to analyze their sensitivities in different cases.
