48716 由于设计与材料的缺陷以及制造过程中的不稳定性,通常在一批产品的生产过程中会产生一定比例具有较高突发失效率的缺陷产品。 Due to the defects of its design and materials and the instability in the process of manufacturing, usually in a batch of products will produce a certain proportion in the production process has high failure rate of defective product.
48717 为了尽量剔除缺陷产品,提高整批产品的实际使用可靠度并减少寿命周期费用,需要进行老练筛选并确定最优的老练时间。 As far as possible in order to eliminate defective products, and improve the reliability and reduce the actual use of the whole batch of products life cycle cost, the need for sophisticated screening and determine the optimal tact time.
48718 在假设突发失效时间服从指数分布、性能退化轨道以Wiener过程描述的基础上,针对同时包含突发失效和退化失效的产品,本文首先建立了包含退化失效的混合竞争失效模型; In sudden failure time are assumed to be exponential distribution, performance degradation orbit to Wiener process, on the basis of describing to contain both sudden failure and degradation products, this paper established the include degradation failure of mixed competition model;
48719 然后以平均剩余寿命(mean residual life,MRL)为目标函数建立了老练试验优化模型的有效性,并给出了数值求解方法;最后通过数值实例验证了所提出的老练试验优化模型的有效性,并对模型参数进行了灵敏度分析。 Then the average remaining life (mean residual life, called simply MRL) as the objective function to establish the validity of the optimization model of sophisticated test, and presents a numerical method;Finally, numerical examples verify the effectiveness of the proposed optimization model of sophisticated test, sensitivity analysis and the parameters of the model.
48720 针对随机恒速运动目标条件下已知的目标初始位置分布密度和速度分布密度,建立了时变的运动目标分布密度模型和在离散时间点上实施有限区域探测后的目标分布密度模型。 For random known target under the condition of constant speed moving targets in the initial position distribution density and velocity distribution density, the establishment of a time-varying moving target distribution density model and the implementation of limited area at discrete time point after detection of the target distribution density model.
48721 以此为基础,提出了依次探测的单次探测发现概率最大的最优搜索准则,计算在该准则下的离散时间点上有限探测域的最优探测位置。 On this basis, put forward, in turn, detection of single found the optimal search criteria, with the highest probability calculation under the guidelines of discrete time point limited detection domain of optimal position.
48722 最后,给出了一个二维空间搜索算例。 Finally, a two-dimensional space search example is given.
48723 根据装备维修保障力量特点,以优化维修保障力量配置为目标,结合粗集(rough sets,RS)和多属性群决策理论,引入直觉模糊集(intuitionist fuzzy sets,IFS)处理复合型决策数据,建立基于IFS多属性粗集群决策的知识系统,用诱导集结算子融合群组信息,定义基于交叉熵的得分函数,并基于其评估结果构建粗集决策系统。 According to characteristics of the power equipment maintenance support, maintenance support power configuration as the goal, to optimize the combination of rough set, rough sets, RS) and multiple attribute group decision making theory, the introduction of intuitionistic fuzzy sets (intuitionist fuzzy sets, the IFS) processing complex decision-making data, based on IFS multi-attribute cluster decision knowledge system, with the induction group messaging rally operator fusion, define the score function based on cross entropy, and based on the evaluation results to construct a system of rough set decision-making.
48724 采用综合的粗集信息熵属性重要度及粗集权重方法确定属性权重,通过对象的综合评价值判断其优劣,对装备维修保障力量进行优选排序。 Adopt the integrated rough set entropy and centralization of attribute importance weight method to determine the attribute weights, through object the value judgment of its advantages and disadvantages, optimization of equipment maintenance support forces.
48725 实例分析结果符合实际,最优排序结果为决策者提供技术支持。 In line with the actual example analysis results, the optimal sorting results provide the technical support for decision makers.
