Reliability design is a kind of modem design method based on probabilistic method and mathematical statistics , whose goal is the reliability of product 可靠性设计是以概率论和数理统计为基础,以产品可靠性为目标的一种现代设计方法。
Markov ' s inequality and four kinds of lovasz local lemma , and give different applications in hypergraphs with these probabilistic methods , we find different conditions for a hypergraph to be 2 - colorable with some kinds of thinkings ) sz局部引理的内容,给出了这几种概率方法在超图上的应用,用几种思路找到了超图存在2 -可染色的不同条件,其中着重对一般形式的lov (
Alike with the convex modeling of uncertainties , the presented method requires less for available information than probabilistic method , thereby , which provided a possible choice for the reliability analysis and design of structures when available information is lack or limited 和不确定性的凸集模型描述一样,所提方法对不确定参量已知数据的要求较低。且直观、简捷。从而为掌握数据信息较少时结构的可靠性评估提供了依据。
Based on the facts in our country , this paper raised that the method of probability should be used in electrical tractor system . and at the same time , the main problems and availableln of this method . based on matlab , the model of probabilistic method and monte carlo simulation in superposition multi - harmonics sources are compared 与此同时,探讨了目前国内外对该问题处理所使用的方法的局限性和缺陷,针对本国的电牵引系统的实际情况,提出了在电牵引系统的多谐波叠加中使用基于中心极限定理的概率分析方法,指出针对高次谐波运用该方法的可靠性和对低次谐波不能有效模拟的原因所在。
The probabilistic method is a nonconstructive method, primarily used in combinatorics and pioneered by Paul Erd?s, for proving the existence of a prescribed kind of mathematical object. It works by showing that if one randomly chooses objects from a specified class, the probability that the result is of the prescribed kind is more than zero.
