“…A methodology for estimating the dependability of offshore wind turbine blades with high availability and cost-effectiveness was presented by Zhang et al (2023) [112] by integrating the direct probability integral method (DPIM) with transfer learning (TL). Based on the Physics-of-Failure (PoF) theory, Mulenga et al (2022) [113] presented a methodology for forecasting the emergence of a fracture in corroded structures. Gu et al (2023) [114] introduced a new framework for creep-fatigue reliability assessment of hightemperature components, in which the engineering damage mechanics technique is used to integrate the physics of failure and monitoring data into the natural degradation process.…”

PLCs, or programmable logic controllers, are essential parts of contemporary industrial automation systems and are responsible for managing and keeping an eye on a variety of operations. PLC reliability is critical to maintaining industrial systems' continuous and secure operation. A wide range of reliability strategies were used to improve the reliability of Programmable Logic Controllers, and this article methodically looks at them all. The evaluation classified PLC reliability techniques into Root Cause Analysis (RCA), Reliability Centered Maintenance (RCM), Hazard analysis (HA), Reliability block diagram (RBD), Fault tree analysis (FTA), Physics of failure (PoF) and FMEA/FMECA, after thoroughly reviewing the body of literature. The proportion of reviewed papers using either RCA, RCM, FMEA/FMECA, FTA, RBD, RCM, PoF, or Hazard analysis to increase the reliability of PLCs showed that RCA, which makes up 20% of the publications reviewed, has been used the most to increase the reliability of the PLC, followed by HA, RCM, RBD, FTA, and PoF, which account for 17%, 16%, 16%,13%, 10%, and 8% of the articles reviewed, respectively. The paper discusses new developments and trends in PLC reliability, such as the application of machine learning (ML) and artificial intelligence (AI) to fault detection and predictive maintenance.

This paper describes a machine visual recognition method for the surface rust recognition of metals. The corrosion images of iron-based metals (HT200, Q345B, 45 steel and 304) under the specific conditions can be accurately recognized by the proposed method. Based on the rust recognition method, the corrosion area percentage (CAP) of each metal block is calculated. The CAP results indicate that HT200, Q345B and 45 steel are rapidly corroded (CAP over 86 % after 192 hours), but 304 is slightly corroded (CAP: 1.7 % after 192 hours) under the periodic immersion condition. The correlation analysis between CAP values and actual weigh loss values is carried out to evaluate the proposed method. The results show that there is a high correlation between CAP values and actual weight loss values of each metal block. Therefore, CAP values calculated from the rust recognition method can quantitatively identify the corrosion degree of the metal blocks. No matter what type of the iron-based materials is, the corrosion degree of metals can be assessed by the rust recognition method. Even the serious corroded metal blocks, the corrosion degree can be determined through the surface rust recognition.

“…Furthermore, reliability theory has been employed to establish maintenance strategies for pipelines and compressors. Mulenga constructs a time-dependent failure probability assessment model for corroded pipelines to determine the optimal maintenance strategy for corroded pipelines [9]. Safiyullah developed a compressor degradation model using genetic programming to provide support for compressor maintenance strategy.…”

As an essential part of the natural gas supply chain, the safe and reliable operation of the natural gas pipeline system is vital to energy supply security. When accidents occur in the natural gas pipeline system, determining the maximum allowable repair time of the failed unit is a crucial factor in balancing maintenance resources against risks of gas shortage. Therefore, this paper proposes a methodology to determine the maximum allowable repair time for critical units of natural gas pipeline systems using gas supply reliability theory, considering system uncertainties as well as the line-pack effect. The methodology is composed of three parts. Firstly, the supply reliability indicators are proposed from the perspective of gas shortage. Secondly, the gas supply reliability evaluation model for the natural gas pipeline system is developed considering system uncertainties and the line-pack effect. Finally, the maximum allowable repair time is determined based on gas supply reliability and target reliability. Furthermore, a real natural gas pipeline system located in China is applied to confirm the feasibility of the methodology. The results demonstrate that the proposed methodology can serve as part of a Reliability Centered on Maintenance (RCM) analysis and provide guidance to support maintenance managers in making data-driven decisions.
