Aiming at the reliability of suspension subsystem and power subsystem , fault tree analysis is adopted to solve it . importance degrees to various parts in these two subsystems are studied , and some requirements for the reliability of key parts are put forward 针对悬浮系统和电源系统的可靠性问题，本文采用故障树分析法对其进行了失效分析，研究了各部件在系统中的重要度，并对关键部件的可靠性程度提出了要求。
Considering the above facts , through studying the existing reliability indexes and finding the shortcoming of them , i propose a new reliability index of importance degree . the importance degree index is used both for the isn in condition of war and natural failures 在对现有可靠性指标的研究基础之上，针对现有网络可靠性指标对于评价保障网络可靠性的不足之处，提出了新的评价保障网络可靠性的指标，即重要度。
First , all topological features in the original mesh model are stored , then sort all the edges according to the importance of vertex , finally delete the edges which lead to sliver triangle and which lead to the discontinuity of triangle normal vectors 该算法首先保存原始网格模型中所有顶点的拓扑特征,然后根据顶点的重要度对所有的边进行排序,通过检查是否产生狭长三角形和三角片的法矢是否连续来判断边是否被删除。
This paper also discussed the caculating of index weight the thesis adopted reformative ahp and fuzzy clustering method to calculate relatively important degree weight of index . through specialist ' s grade , this article use principle of collecting value counts to calculate reliable degree weights 应用改进ahp法与模糊聚类相结合的方法确定了指标相对重要度权重，通过专家打分，运用集值统计原理计算出指标可靠度权重。
Combined with gqfd method and development of e - gov . system , collection of comprehensive evaluation indexes including collecting , optimizing , and determining of importance is realized . in the end of this paper , the author applies the innovative model to cases to testify its correctness and validity 当进行事前、事中、事后三种评价时,由于重要度不一样,各个阶段的权重不一样,评价的结果也会不同,这样三个阶段的指标体系就动态地联系起来。
By using the method of fault tree analysis , this paper analyses the causes of fire and explosion of catalying & cracking reactor and regeneration , draws the fault trees of fire and explosion accidents of catalyzing & cracking reactor and regeneration respectively , calculates the structure importance , makes the structure importance arrangement according to the structure importance and the least path set , puts forward the prevention measures , and provides the reliable theoretical basis for the safety control of enterprises 摘要应用故障树分析方法，对催化裂化反应器和催化裂化再生器发生火灾（爆炸）事故的原因进行分析，分别画出催化裂化反应器和催化裂化再生器发生火灾（爆炸）事故的故障树，得出最小径集合，并计算其结构重要度，根据得出的最小径集合及其结构重要度进行排序，提出预防措施，为企业的安全管理提供了可靠的理论依据。
The concepts of planned improved increment , actual improved increment and possibility factor of competitive seating arrangement on the customer requirements were introduced as an exact measurement of the enterprise ' s desire to improve product competitiveness , and then the formulas of calculating the correct factor of the fundamental importance ratings were developed 通过引进顾客需求竞争位次的计划改进增量、实际改进增量和可能性因子等概念来表征企业改进产品竞争力的意愿，进而提出了基本重要度的修正因子计算公式。
In accordance with this problem , this paper applied highway network and pavement performance to study the evaluation of highway technique . using fuzzy mathematics method and functional degree of importance method etc in the course of research , and establishes the evaluation of the highway technique method system , and apply this evaluation system in the evaluation research of highway construction and highway network development condition of meishan of sichuan province , good evaluation efficiency has been obtained 针对这一问题，本课题从公路网和公路的使用性能两方面对公路技术评价进行了深入系统的研究。在研究过程中，采用模糊评判法、功能重要度系数法等数值分析方法，建立公路技术评价体系，并将此评价体系应用到四川省眉山市公路建设和公路网发展状况的评价研究中，取得了良好的评价效果。
For the quantification risks , the " geometric mean " is selected as the tool to rate the risk level ; for the qualification risks , the ahp approach was used to illustrate the different risk level . 4 、 the ahp method was proposed to determine risk response plan . by this approach , the various risks knowledge dispersed within the risk management organization such as the managers " experience and project history data can be used for the project risk management 为了解决风险因素特性的难于量化问题，本文还另外给出了风险重要度的定性整合ahp方法； 4 、提出了风险响应措施拟定与选择的ahp方法；该方法可以有效地利用分散于项目管理机构中的风险信息（经验、数据） ，选择出最适宜的风险响应措施； 5 、提出了工程项目风险管理的循环周期概念，通过该周期的循环体现项目风险管理的面向过程性和动态性；将周期性风险管理与项目本身的生命周期有机地结合，提出了一个面向过程的项目风险动态管理框架体系。
