Reliability-based selective maintenance for redundant systems with dependent performance characteristics of components
نویسندگان
چکیده
The reliability-based selective maintenance (RSM) decision problem of systems with components that have multiple dependent performance characteristics (PCs) reflecting degradation states is addressed in this paper. A vine-Copula-based reliability evaluation method proposed to estimate the system PCs. Specifically, marginal each PC built by using Wiener stochastic process based on PC's mechanism. joint component PCs established connecting D-vine. In addition, two RSM models are developed ensure accomplishes next mission. genetic algorithm (GA) used solve constraint optimization models. numerical example illustrates application method.

Fuzzy Reliability Optimization Models for Redundant Systems
In this paper, a special class of redundancy optimization problem with fuzzy random variables is presented. In this model, fuzzy random lifetimes are considered as basic parameters and the Er-expected of system lifetime is used as a major type of system performance. Then a redundancy optimization problem is formulated as a binary integer programming model. Furthermore, illustrative numerical ex...
متن کاملCondition Based Maintenance for Two-Component Systems with Reliability and Cost Considerations
This paper studies a maintenance policy for a system composed of two components, which are subject to continuous deterioration and consequently stochastic failure. The failure of each component results in the failure of the system. The components are inspected periodically and their deterioration degrees are monitored. The components can be maintained using different maintenance actions (repair...

متن کاملa new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
