摘要
论文在基于统计方法的基础上提出了一种根据数据集合本身的统计特性确定决策系统故障预测控制上限的计算方法。该算法利用决策系统故障状态的影响因素的观测数据本身的统计特性对数据进行分析,在对原始数据进行归一化处理之后,通过误差平方和的计算给出了决策系统故障预测控制上限的计算模型和故障预测的流程图设计。该模型充分考虑了系统本身的运行情况,极大的改善了控制上限给定的客观性。分析表明,这种模型是有效的。
According to statistics characteristic of the data sets a Calculational Method of Control Upper - boundary for Fault Prediction of Decision Systems, is presented by statistic way. First of all, the algorithm analyzes the data using statistic measures of observation data of the influencing factors for Fault Prediction of Decision Systems. Secondary, we deal with the initial data using unitary principle. Finally, the calculational model of CUBFPDS is given by the error square sum. It considers adequately the running state of Systems and greatly improyes the objectivity of given CUB. The analysis indicates that the model is effective.
