摘要: 求故障函数不相交积之和的表达式是定量分析大型复杂系统可靠性的关键步骤.对此本 文提出三种新算法:原始Sharp法、递归Sharp法和直接Sharp法,后两种更适合大型复杂 系统的近似计算.Abstract: It is well known that fault tree is one of the important models for reliability analysis of large and complex systems. To obtain disjoint S. O. P. expression of failure function is the key to quantitative analysis of system reliability. Three new algorithms named primary sharp method, recursive sharp method and direct sharp method are proposed in this paper. The last two methods are more suitable for approximate calculation of large and complex systems.
