摘要 ：
控制棒驱动机构钩爪组件是核反应堆中重要的运动部件,其可靠性直接影响反应堆的正常运行。基于ANSYS workbench软件,对承载工况下的钩爪组件进行了静力学仿真,在仿真的基础上,赋予了输入变量的分散性,对钩爪的应力应变进行不确定性分析,并对其进行可靠性分析。分析计算结果显示,承载工况下的钩爪组件应力最大值出现在钩爪齿,3根销轴中钩爪轴所受应力最大;当前钩爪齿的强度可靠性较高,可以安全可靠的工作,后期需要重点关注钩爪齿的疲劳失效状态。

摘要 ：
With the progression of technology, models of linear multistate consecutively-connected systems (LMCCSs) have been applied more widely, such as in telecommunication systems and the Internet of Things, among other applications. LMCCSs contain a series of linearly arranged nodes, and any disconnection between nodes will lead to the failure of the entire system. Thus, the reliability of a linear multistate system is affected by many factors, such as the positioning of elements. To be able to incorporate different types of complicated practical factors, researchers have proposed various extensions for the LMCCS model. Moreover, models have been proposed to study the optimal system configurations of such systems while considering reliability and some other objectives or constraints. Due to the amount of existing research on LMCCSs, this paper aims to review the related literature, classify these works, and elicit some future research directions. © 2021 Bentham Science Publishers.

摘要 ：
In this paper, we consider a repairable circular consecutive-k-out-of-n: F retrial system, which can be used to simulate the intelligent closed recurring water cooling automation system in industrial production. We assume that the working time and retrial time of each component obey exponential distributions, and the repair time obeys a general distribution. Based on the generalized transition probability and the key component priority repair rule of the retrial system, the availability and reliability indices of the general repairable circular consecutive-k-out-of-n: F retrial system are derived by using the methods of supplementary variable and Laplace transform. Furthermore, we calculate the explicit expressions of the above indices when n and k are fixed at definite values in the system. The repair time is assumed to follow a Weibull distribution in examples demonstration, and the influence of various parameters on system reliability, steady-state availability and other indices are obtained. The sensitivity and relative sensitivity analysis of the steady-state availability, steady-state failure frequency and mean time to first failure (MTTFF) of the system are also performed.

摘要 ：
The reliability of a system that shares a single type of resource with others has been studied in the literature. In reality, a system may require different types of resources. For example, a building service system may be powered by electricity (for lighting) and gas (for heating). However, in the literature, research in this area is scarce. This paper therefore investigates the reliability of a system with multiple nodes. Each node has demand requirement for two types of resources, which can be shared among the system nodes subject to their bandwidths, respectively. In addition, the resources may be able to substitute each other. This paper considers both unidirectional and bidirectional substitutions. The system is said failed if either resource supply in a node is smaller than its demand even after performance substitution and sharing. A universal generating function technique is proposed to evaluate the system reliability. Numerical examples are presented to illustrate the applicability of the model. The influences of bandwidths and substitution rates on system reliability are also discussed. © 2021 Elsevier Ltd

摘要 ：
In practical engineering, the presence of dependent evidence is not rare due to various imperfections. Misuse of such information in reliability analysis will lead to conflicting or even erroneous results. In this paper, we propose a Bayesian reliability approach for complex systems with dependent life metrics. Notions such as explicit evidence and implicit evidence are established based on an identification of different roles of multiple dependent evidence in the likelihood construction. A likelihood decomposition method is developed to convert the overall likelihood into a product of Explicit Evidence-based Likelihood (EEL) function and Implicit Evidence-based Likelihood (IEL) function. An inferential diagram is developed to intuitively generate the required implicit evidence taking both outer-source information and the system configuration into consideration. An algorithm is then presented for implementation. The contribution of our work is a systematic investigation of the role of dependent evidence in system reliability evaluation and a full Bayesian approach that is applied to various system reliability models. Extensive numerical cases and a practical engineering case are demonstrated for validation and to illustrate the benefits of our approach. © 2021 Elsevier Ltd
