Reliability Enhancement Through Performance Sharing in Circularly Balanced System

This study examines a circularly balanced performance sharing system incorporating a circular common bus. A new type of balance is proposed to address real‐world problems, where system balance is linked to its symmetry. The system consists of four subsystems, each containing components. The system is considered balanced if all four subsystems maintain symmetry with respect to each other within a defined balance threshold . System failure occurs if this symmetry is disrupted, resulting in imbalance, or if any subsystem has fewer than working components. A subsystem with fewer than working components is referred to as a failed subsystem. In existing studies, circularly balanced systems have not incorporated a common bus. Consequently, balance restoration relied on deactivating and reactivating components, leading to performance losses. To mitigate this issue, a novel approach is proposed that restores system balance by transferring surplus performance to deficit performance components through the circular common bus. Recognizing the significance of the surplus performance and the transmission capacity of the common bus, two algorithms are introduced. Algorithm 1 identifies performance deficit components that require the minimal surplus performance needed to restore system balance. Algorithm 2 focuses on identifying performance deficit components that require the least surplus performance to restore the working status of all subsystems while maintaining overall system balance. The universal generating function technique‐based method is used to evaluate the reliability of the system. A numerical example of a solar‐powered unmanned aerial vehicle (SUAV) illustrates the proposed method, offering valuable insights into system's reliability.
