Special Issue Information

Dear Colleagues,

Modern industries are becoming highly integrated and developing overwhelming complexities, which simultaneously entails benefits and potential risks with catastrophic consequences. Reliability engineering, as an engineering discipline, develops rapidly throughout the whole lifecycle management of industrial systems, covering system analysis, system design, operation and maintenance, etc.

This Special Issue aims to report cutting-edge methods and techniques in reliability-related fields by highlighting research on these key issues.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Reliability modelling and analysis of complex systems;
  • Reliability-based design optimization (RBDO) methods;
  • Risk analysis and reliability assessment for large-scale complex systems;
  • Predictive maintenance schemes and decision-making optimization;
  • Statistical methods for degradation modelling;
  • Machine learning techniques and applications in reliability engineering;
  • Uncertainty quantification and analysis for safety-critical systems;
  • Bayesian methods for reliability analysis. 

We look forward to receiving your contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Axioms is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs).

Abstract
This paper proposes a system made up of four subsystems connected in sequence. The first and third subsystems each have one unit, the second has two, and the fourth has three. Every subsystem operates in parallel and is governed by the K-Out-of-n:G rule. [...] Read more.
This paper proposes a system made up of four subsystems connected in sequence. The first and third subsystems each have one unit, the second has two, and the fourth has three. Every subsystem operates in parallel and is governed by the K-Out-of-n:G rule. Nonetheless, each subsystem needs at least one operational unit in order for the system to work. While a unit’s failure has an exponential distribution, repair is simulated using a general distribution and a distribution from the Gumbel–Hougaard family of copula. This study’s primary objective is to assess and contrast the system performance while our system is running under these two different repair policies. The problem is solved by combining the supplementary variable technique with Laplace transforms. We use reliability metrics to assess system performance. The second objective of this study is to present a reduction approach plan aimed at improving the overall reliability metrics of our system. Full article
