Review Models and Methods for Determining and Predicting the Reliability of Technical Systems and Transport

Abstract

Modern power and transportation systems are subject to high requirements for reliability and performance in performing their specified functions. At the same time, these requirements are constantly increasing with the increasing complexity of technology and the introduction of electronics and computer technology into its structure. This is fully applicable to energy and transportation infrastructure, including electric vehicles. The complexity of the systems and increasing requirements for them have led to the fact that the problem of increasing their operational reliability has acquired great importance. The article presents a review of methods and justification of ensuring a high level of reliability and serviceability of technical systems as one of the most important tasks in the creation and operation of complex systems, such as modern energy and transportation systems. It is shown that a significant reserve in solving the problem of increasing the reliability and performance of technical systems is the information on failures and malfunctions of these systems obtained from the field of operation. The methodology of collection and processing of statistical information on failures of vehicles described by different distribution laws is outlined.

Longevity, Chronic Conditions and Ageing Dynamics: A Mathematical Reliability Perspective. Review

“…In response to these challenges, studies have advocated for adapting engineering concepts to biological systems, addressing the complexities of living organisms, and integrating mathematical and theoretical frameworks to enhance our understanding of the ageing phenomenon. Martyushev et al (2022) explore models and methods for assessing the reliability of technical systems and transportation, indirectly highlighting the significance of reliability theory in ageing research, which can elucidate the factors influencing the reliability of biological systems [13]. Gavrilov and Gavrilova (2001) introduce the Reliability Theory of Ageing and Longevity, providing a theoretical framework grounded in engineering principles to explain the ageing process [12].…”

“…This potent framework has found extensive application in assessing and comprehending the longevity and dependability of complex systems, processes, and components over time [12]. Mathematical reliability theory offers a systematic and rigorous avenue for comprehending how systems endure and function over extended periods [13]. Building upon this theoretical foundation, this review elucidates the foundational concepts essential for evaluating and predicting the dynamics of ageing in systems, encompassing both the human and non-human spheres.…”

“…Building upon this theoretical foundation, this review elucidates the foundational concepts essential for evaluating and predicting the dynamics of ageing in systems, encompassing both the human and non-human spheres. Ageing, at its core, is a complicated phenomenon, shaped by an interplay of biological, psychological, and sociological forces, and is influenced by an array of genetic, environmental, and lifestyle factors [13]. Below is a table outlining the theories of ageing, their pre-existing definitions, and their relationships to lifestyle diseases and chronic conditions.…”

Reliability by Using Weibull Distribution Based on Vibration Fatigue Damage

“…That description can be performed by using a probabilistic approach [5]. Then, for mechanical components or systems, according to their application and data complexity, an accurate method must be selected to determine an effective level of service life reliability [6]. Now, since data from fatigue damage are affected by significant scatter, and damage is provoked as a response to random forces, gathering fatigue damage data is generally a difficult activity [7].…”

Multi-Mode Lithium-Ion Battery Balancing Circuit Based on Forward Converter with Resonant Reset

“…Consequently, its diagnostic results always depend on highly reliable mathematical models and analysis methods. The mathematical models and analytical methods proposed in [8][9][10] can be applied to SOH to improve the reliability and accuracy of its diagnostic results. For healthy lithium-ion batteries, battery balancing techniques are usually employed to address the inconsistency of cells in the battery pack [11,12].…”
