Computer simulation of processes of changing the reliability characteristics of systems with recoverable and non-recoverable elements based on the Simulink Dynamic Simulation Package

Abstract

The paper presents a methodology and software package of mathematical and computer simulation of changes in the reliability characteristics and integrated indicators of system reliability during operation using Simulink. The software package is an application (Toolbox) to the standard Simulink package. The theoretical basis of the proposed algorithms is the method of analyzing structural diagrams of system reliability. The author proposes an original diagram of building a mathematical model of reliability with both non-recoverable and recoverable elements. The diagram involves a broad interpretation of the concepts of a “recoverable element” and a “recoverable element failure”. This approach found reflection in the wide range of proposed simulation tools. The advantage of the proposed products is the unification and relative ease of building models of systems of a sufficiently high level of complexity, and a wide range of intermediate simulation results available for analysis. The methodology and software package can be used during the system design stage to predict their reliability performance. The paper presents some simulation results.
