چکیده

We present a concise overview of imprecise reliability, particularly focussing on reliability theory with uncertainty quantified via lower and upper probabilities. We discuss the main approaches and opportunities of the theory, we include references to guide further study, and we briefly discuss some research challenges.

Imprecise reliability: An introductory overview

The main aim of this paper is to define what imprecise reliability is, and discuss a variety of problems that can be solved by means of a framework of imprecise probabilities. From this point of view, various branches of reliability analysis are considered, including analysis of monotone systems, repairable systems, multi-state systems, structural reliability, software reliability, human reliab...

Imprecise Reliability Models for the General Lifetime Distribution Classes

To develop a general reliability theory taking into account various sources of information and a lack of satisfactory data on which estimates of system parameters can be based, the theory of imprecise probabilities can be used. The purpose of the paper is to study structural reliability based on the imprecise probability models taking into account the ageing aspect of the lifetime distributions...

Imprecise reliability by evidential networks

This article deals with an implementation of probist reliability problems in evidential networks to propagate imprecise probabilities expressed as fuzzy numbers. First, the problem of imprecise knowledge in reliability problems is described concerning system and data reprsentation. Then, the basics of the evidence theory and its use in a directed acyclic graph approach are given. The imprecise ...

Interval assessments in structural reliability using the imprecise Dirichlet model

A new approach to structural reliability analysis under incomplete information about the stress and strength in the form of intervals provided by experts or obtained as a result of imprecise measurements is proposed in the paper. The approach takes into account the possible fact that the number of judgments or observations may be rather small. It is shown that interval-valued information about ...

Reducing Uncertainty by Imprecise Judgements on Probability Distributions: Application to System Reliability

In this paper the judgement consisting in choosing a function that is believed to dominate the true probability distribution of a continuous random variable is explored. This kind of judgement can significantly increase precision in constructed imprecise previsions of interest, which of great importance for applications. New formulae for computing system reliability are derived on the basis of ...
