运用可靠性工程理论及不交型积之和定律 ,在大型网络系统可靠度计算的基础上 ,提出了矿井通风网络系统最大线性无关最小独立路集予以真子集涤除的不交化可靠度计算的实现方法 .根据不交化可靠度计算法 ,当最小独立路集按所含网络分支的多少进行升序排列时 ,还可进一步减少中间过程的计算量 ,从而达到最佳不交化简化计算的效果 .实例分析表明 :采用升序排列的最小独立路集并按不交型积之和定理予以真子集涤除的不交化处理后 ,不仅计算值等同于一般网络分析中用全概率公式计算的矿井通风网络系统可靠度 ,而且 ,计算工作量大为简化 .
Based on the reliability theory of large-scale network system and the reliability engineering theory and the law of sum of non-product-type products, this paper presents the calculation of the disjunction reliability of the maximal linear independence independent minimum path set in mine ventilation network system According to the disjunction reliability calculation method, when the minimum independent route set is sorted in ascending order according to the number of network branches, the calculation amount of the intermediate process can be further reduced so as to achieve the best effect of not simplifying the calculation. The case study shows that not only the minimum independent path set in ascending order but not the sum of subsets of products and the non-intersecting treatment of true subset removal, not only the calculated value is equal to the mine ventilation calculated by the total probability formula in the general network analysis Network system reliability, but also greatly simplify the calculation workload.
