gray
    The rationality of predicting city fire based on gray system theory is given. Founding on common gray theory model of GM(1,1), the original data is treated and transformed. Using the above method, fire occurrence of some city is analyzed according to different period of time.
    提出利用灰色系统理论对城市火灾进行预测的合理性 ,在一般灰色系统模型 GM(1 ,1 )的基础上 ,通过利用等维灰色递补动态预测模型为基础对原始数据预处理及变换后 ,结合对城市火灾按不同分时段进行预测比较 ,最后以某市近年来的火灾状况为例进行了预测 ,结果表明基于灰色系统理论进行分时段预测城市火灾发生时结果更精确 .
    According to gray theory, the gray GM(1,1) model for predicting the outflow of min is established in the paper, at the same time the established GM(1,1) model is modified with the residual sequence.
    应用灰色系统理论,建立了预测矿井瓦斯涌出量的灰色系统GM(1, 1 )模型,并用残差序列对预测模型进行了修正。

    基于灰色聚类评价法、BP神经网络原理和掘进面瓦斯爆炸的特点,设计了BP神经网络掘进面瓦斯爆炸危险源安全评价过程图。
    Gray prediction is suitable for such kinds of system objects with few data,short time and little fluctuation,and Markov chain theory is just suitable for forecasting stochastic fluctuating dynamic process.
    灰色预测适合于时间短、数据量少和波动不大的系统对象,而马尔可夫链理论适用于预测随机波动大的动态过程.
    By combining the advantages of both gray prediction and Markov chain theory,a new gray Markov SCGM(1,1)_C model is proposed.
    结合灰色预测和马尔可夫链理论的优点,提出了一种灰色马尔可夫SCGM(1,1)C模型.
    The single gene system cloud gray SCGM(1,1)_C model is applied to imitate the development tendency of the forecast system while Markov prediction is used to forecast the fluctuation along the tendency.
    用单因子系统云灰色SCGM(1,1)C模型拟合系统的发展变化趋势,并以此为基础进行了马尔可夫预测.
