Computational Intelligence in Reliability and Maintainability Engineering

by Platilha Salgado, Marica De Fatima; Carminhas, Walmir Matos; Rodrigues de Menezes, Benjamin

In this paper the basics of reliability and maintainability modeling, prediction and optimization problems using stochastic models are briefly reviewed (for non-repairable and repairable systems)..

Step Stress Accelerated Life Testing Data Analysis for Repairable System Using Proportional Intensity Model

by Luo, Min; Jiang, Tongmin

In this paper, a “minimal repairing” approach for the repairable system is assumed. The Paw Law Process (PLP) is modeled to describe the reliability change process of the repairable system...

On Determining Sample Size and Testing Duration of Repairable System Test

by Guo, Huairui; Pan, Rong

This paper develops a theoretical method, based on pivotal quantities and a confidence bound requirement for the reliability metrics of interest, to help test planners to determine the minimal sample sizes and test duration..

Changes in Items’ Failure Pattern during Maintenance: An Investigation of the Perfect Repair Assumption

by Block, Jan; Soderholm, Peter; Tyrberg, Tommy

It is clear that the simple ‘perfect repair’ assumption is not immediately applicable to any of the studied types of hardware, i.e. Cooling Turbine, High-Voltage Generator, Hydraulic Accumulator, and Radar Transmitter..
