“…The system fails if there are r consecutive subsystems in which at least k subsystems fail, and the system reliability was analyzed using the Markov processes and finite Markov chain imbedding approach. Huang et al [12] considered a k-out-of-n: F load-sharing system with a protective device that is operating in a shock environment. In the system model, the hazard rate of the system is affected by random shocks that is classified into two types: invalid and valid shocks.…”

This paper considers a circular k-out-of-n: G balanced system equipped with homogeneous and stationary units. Such a system consists of n identical and circularly arranged units where the system is considered as reliable if at least k units are non-failed while maintaining a specific balance condition. Building on the previous two research studies which proposed two such balance conditions based on symmetry and proportionality concepts, this paper introduces a new balance definition that incorporates the concept of the center of gravity. According to the proposed balance definition, a circular k-out-of-n: G balanced system is considered balanced if its center of gravity formed by the operating units is located at the geometric origin of the system. This new balance condition is not only simple but also advantageous as it covers the previously introduced two balance conditions. To evaluate the system's reliability, we consider the minimum tie-sets, and extensive numerical studies verified the improvement of system reliability resulting from the proposed balance definition.

“…The k-out-of-n structure is widely used in both industrial and military systems [5]. An n-component system is said to be a k-out-of-n system, 1 ≤ 𝑘 ≤ 𝑛, if it operates as long as at least k components out of n operate [6], [7].…”

As an important aspect of reliability theory, availability has now been considered a very meaningful design criterion of repairable system. This paper investigates the availability evaluation and design optimization of the multi-state k-out-of-n: G system considering random weight threshold. The system availability is evaluated by extending the recursive algorithm (RA) and universal generating function (UGF) technique. Based on the traditional recursive algorithm, the total probability theorem is used to solve the discrete random weight threshold. Another better UGF method combines a new stochastic joint operator, which is suitable for both continuous and discrete random weight thresholds. Furthermore, we constructed two system design optimization models under availability or cost constraint respectively, and genetic algorithm (GA) programming can be applied to obtain the optimal state probability distribution and weight distribution of multi-state components of the suggested system. Finally, through numerical examples, the flexibility and effectiveness of the proposed methods for design optimization are demonstrated. In addition, two evaluation methods are compared to show that the customized UGF method features higher generality than RA in the case of continuous stochastic weight threshold, and higher operational efficiency in the case of increasing component quantity and state. The results can be helpful for engineers to optimize the design of complex systems.
