cumulative sample
cumulative sample 双语例句
It draws grey hierarchical evaluation method into anti-helicopter intelligent mine warhead's overall efficiency. In fixing sample matrix, it presents the method which effect function value of all the performance index take the place of decision-maker's mark and takes sample matrix to have reliability and science. Problems of overall efficiency evaluation of anti-helicopter smart mine Warheads are discussed, where techniques on artificial neural networks are used. The evaluation model and algorithm of neural network have keen given out. By comparing the evaluation result on method of hierarchical TOPSIS with the evaluation result on method of neural network, the evaluation results show the evaluation result based on neural network has less dependence on the subjectivity of decision-maker. The paper makes use of the theory of Grey system forecast to resolve the problem of ammunition and rocket system development cost evaluation, establishing the GM model of Grey systems and cumulative residual error model, then correcting the GM forecast model.
给出了反直升机智能雷战斗部总体效能的评价体系，对各种评价方法进行了分析，在TOPSIS方法中引入层次结构的概念，提出了适用于智能雷战斗部总体效能评价的层次TOPSIS评价方法，采用效用函数法进行指标值的统一量化，并给出了权向量的计算方法；引入了灰色层次评估法对反直升机智能雷战斗部总体效能进行评估，在确定样本矩阵方面，本文提出了用性能指标的效用函数值取代由评估者评分的方法，使得样本矩阵更具有可靠性和科学性；应用人工神经网络技术解决反直升机智能雷战斗部系统总体效能评价问题进行了探讨，给出了神经网络评价模型和算法，对层次TOPSIS法评价结果与神经网络评价结果进行比较，结果表明神经网络的评价结果受决策者的主观性影响较小。
