Presenting a one-objective optimization model to determine the reliability of the components of a coherent system [PDF]
تصمیم گیری و تحقیق در عملیات, 2023 Purpose: In this paper, the amount required to increase the reliability of the components of a coherent system is determined so that the cost of this increase is minimized and the reliability of the whole system is not less than the predetermined value ...

On the Uncertainty Properties of the Conditional Distribution of the Past Life Time
Entropy, 2023 For a given system observed at time t, the past entropy serves as an uncertainty measure about the past life-time of the distribution. We consider a coherent system in which there are n components that have all failed at time t.

Fractional Survival Functional Entropy of Engineering Systems
Entropy, 2022 An alternate measure of uncertainty, termed the fractional generalized cumulative residual entropy, has been introduced in the literature. In this paper, we first investigate some variability properties this measure has and then establish its connection ...

Tsallis Entropy of a Used Reliability System at the System Level
Entropy, 2023 Measuring the uncertainty of the lifetime of technical systems has become increasingly important in recent years. This criterion is useful to measure the predictability of a system over its lifetime.

Cumulative Entropy of Past Lifetime for Coherent Systems at the System Level
Axioms, 2023 This paper explores the cumulative entropy of the lifetime of an n-component coherent system, given the precondition that all system components have experienced failure at time t. This investigation utilizes the system signature to compute the cumulative

Tsallis Entropy for the Past Lifetime Distribution with Application
Axioms, 2023 A fundamental factor in relevant applications is the predictability of the life cycle of a coherent system consisting of more than one component. In this context, we examine how entropy can be applied to evaluate the degree of predictability.

Further Properties of Tsallis Entropy and Its Application
Entropy, 2023 The entropy of Tsallis is a different measure of uncertainty for the Shannon entropy. The present work aims to study some additional properties of this measure and then initiate its connection with the usual stochastic order. Some other properties of the

Cumulative Residual Entropy of the Residual Lifetime of a Mixed System at the System Level
Entropy, 2023 Recently, there has been growing interest in alternative measures of uncertainty, including cumulative residual entropy. In this paper, we consider a mixed system consisting of n components, assuming that all components are operational at time t.
