摘要:

研究多元状态复杂系统的可靠性重要度,有助于分析并确定系统设计的潜在技术薄弱环节,对于实现系统状态性能的精细化管理意义重大。通过引入改进生成函数模型,并构建面向特定“状态可达门限”的系统层级生成函数,给出一类能够适应“多元”状态复杂任务功能系统的可靠性重要度通用化封闭解算体系与高精度分析算法。工程案例验证结果表明:新算法适用范围广、可靠性重要度分辨精度高,更便于实现复杂系统可靠状态的精细化管理;新算法程式化运算资源要求低,可规避大维度复杂系统状态微分解算的技术瓶颈,工程应用价值更突出。研究结果可拓展应用于多元状态复杂系统其他通用质量特性的重要度分析与精细化管理,对于科学筹措配套保障资源、合理规划预防性维修工作具有重要技术指导作用。

Abstract:

Study on the reliability importance of multi-state complex system can help analyze and identify the potential technical weaknesses in system design, and is of great significance for achieving the refined management of system state performance. By introducing an improved generating function model and constructing a system-level generating function for specific state reachable threshold, a generalized closed solution system and a high-precision analysis algorithm for reliability importance that can adapt to complex task functional systems with multiple states are proposed. Engineering case verification shows that the proposed algorithm has a high accuracy in distinguishing reliability importance, and is more conducive to achieving the refined management of reliable states in complex system. Meanwhile, the proposed algorithm has low requirements for programmatic computing resources and can avoid the technical bottleneck of state differential calculation in high-dimensional complex system. Its engineering application value is more prominent. The research results can be used for the importance analysis and refined management of other general quality characteristics in multi-state complex system, and have important technical guidance for scientifically allocating support resources and reasonably planning preventive maintenance work.
