模糊推理在系统预测中的应用

将模糊推理应用于系统预测,使用正态分布原理对变量进行区分,并用模糊聚类中的相关系数法选择特征因子,建立了模糊推理预测模型。并将其应用于能源消费量的预测。     

优序法在管理成果评价中的应用

在对管理成果进行评价时 ,首先要建立指标体系 ,而在这些指标当中有的可以定量描述 ,有的只能定性来描述 ,所以在评价时应当将定性和定量指标进行综合考虑。优序法就是通过对多目标决策问题进行两两相对比较 ,最后给出全部方案的优序排序。此方法应用简单 ,既能处理定量问题 ,又能处理定性问题。在建立管理成果指标体系的基础上 ,利用优序法 ,给出了管理成果评价方法。     

库存导弹定期检测模型的数字仿真研究

储存可使用率是衡量导弹战斗性能的重要指标 ,也是衡量其定期检测有效性的重要参数。本文提出了三种定期检测模型 ,并用效能 /费用评估法分析了这三种模型对导弹的储存可使用率的影响 ,用数值仿真法分析了各模型性能的优缺点 ,为导弹检测部门制定一套最佳的定检方案提供了理论依据。     

SOME DISCUSSION ON THE CONDITIONS OF COMPLETE CONVERGENCE FOR SUMS OF B-VALUED RANDOM ELEMENTSS

1. Introduction and Main ResultsSince the definition on complete convergence of real random variables was introduced by Hsuand Robbins[1], there have been extensive literature on the complete convergence of i.i.d. realvalued random variables, see Baum and Katz ([2]), Bat and Su ([3]). In 1989, Yul4] extendedsome results in Bat and Su ([3]) to real valued independent but not necessarily identicallydistributed case. The main purpose of this paper is to extend the results of Yu[4] to B-value…     

THE DOMAIN DECOMPOSITION TECHNIQUES FOR THE FINITE ELEMENT PROBABILITY COMPUTATIONAL METHODS

1. IntroductionWe have discussed probability computational methods of finite element methods in [1,2,3,4].Probability computational methods have many advalltages. The advantages are more obviousin three dimensions for finite element problems. In probability model, the time that the particlemoves from one place to the boundary of the domain and is absorbed by the boundary (whichis called the time of running up to the boundary for short) is only dependent on the averagedistance between the start…
