Reliability monitoring methods for complicated engineering systems

Abstract

The reliability prediction model of complicated engineering system (CES) was analyzed on different stage of its life-cycle: designing, testing and exploitation. The analytical model was suggested for parameters estimation of maintenance work (MW). It helps obtain a different character of reliability changing. The failure rate growth inside testing cycle leads to the rule of senescent type, which corresponds to exploitation stage. The failure rate decreasing leads to the “burnout” failure model, which corresponds to a testing stage. The numerical evaluation method of maintenance work model parameters was suggested according to the results of full-scale test. The presented algorithm allows to forecast maintenance work parameters for different applications in wide range of given data. The effectiveness increase procedures of maintenance work operation inspection was given with a view to ensuring high index of reliability and safety in complicated engineering system exploitation.
