Summary

As technology continues to advance, the deployment of complex engineering systems in extreme environments has become increasingly common. Throughout their service life, these systems face numerous uncertainties that significantly impact their reliability and security. Addressing these challenges has become a research hotspot in engineering design, and the integration of Artificial Intelligence (AI) in complex system modeling and reliability assessment has proven to be a potent tool. This special issue aims to explore and promote the latest developments in the intelligent methods for structural integrity assessment and design optimization, focusing on the utilization of machine learning techniques.

 

The robustness of AI, particularly machine learning, has been demonstrated in various applications such as condition monitoring, safety assessment, reliability modeling, and analysis of mechanical structures. Existing research has played crucial roles in industries like manufacturing, transportation, installation, monitoring, and maintenance. Despite significant progress, there is a pressing need for more research in this domain, given the increasing complexity of mechanical systems. The challenge lies in developing more efficient and accurate modeling methods, as well as reliability and security analysis methods.

    Abstract The traditional first-order reliability method (FORM) often encounters challenges with non-convergence of results or excessive calculation when analyzing complex engineering problems. To improve the global convergence speed of structural reliability analysis, an improved coati optimization algorithm (COA) is proposed in this paper. In this study, the social learning strategy is used to improve the coati optimization algorithm (SL-COA), which improves the convergence speed and robustness of the new heuristic optimization algorithm. Then, the SL-COA is compared with the latest heuristic optimization algorithms such as the original COA, whale optimization algorithm (WOA), and osprey optimization algorithm… More >
