This thesis is to introduce time series analysis to forecast the delivery time of the pregnant women for the decision support system of the Hospital Information System. The pregnant woman is special forecast object, because it has so much obvious biologic periodicity and some uncertain factor.

本文在现代医院信息系统的决策支持层中引入时间序列分析方法对孕妇分娩时间进行预测,但是孕妇这一特殊的预测对象自身有着非常明显的生物周期性而且具有不确定性。

Finally, the empirical result of the single systemic factor model showed that the common factor Z had periodicity existed; that is to say, if Z was negative in average within the first quarter, then that meant the overall economic situation in that quarter was not good, and affected every enterprises credit ratings declining.

最后,单一因子模型的实证发现,共同因子存在一个周期性,即每年的第一季Z均为负,表示该季总体经济状况不好,使得平均每一家企业的信用评等均下降,每年的二四季Z均为正,表示这三季的总体经济状况良好,使得平均每一家企业的信用评等提升。

The results show that a the variation of annual mean runoff of Huayuankou section exist an intrinsic dynamic mechanism, which is the results of joint action of affecting factor of periodicity and non-periodicity, having obvious chaos characteristic; b the correlation dimension of attractor of phase space is 5.09 and saturation inserted dimension is 14. It shows that to establish a mathematical model of the annual mean runoff system of Huayuankou at least requires 6 independent variables and the required saturation inserted dimension for rebuilding phase space is 14; c the steady estimate of Kolmogorov entropy is 0.14, showing the average predictable time of the annual mean runoff variation of Huayuankou is about 7 years and; d using nonlinear deterministic chaos model is more suitable to describe the variation of annual mean runoff of Huayuankou.

结果表明:①花园口年平均径流量变化存在着内在动力学机制,是由周期性和非周期性影响因子共同作用的结果,具有明显的混沌特性;②相空间吸引子的关联维为5.09,饱和嵌入维数为14,这说明要建立花园口年平均径流系统的数学模型,至少需要6个独立变量,重构相空间所需要的饱和嵌入维数为14;③Kolmogorov熵的稳定估计为0.14,说明花园口年平均径流量变化的平均可预报时间大约为7年;④用非线性确定性的混沌模型比完全的随机模型更适于描述黄河花园口年平均径流量的变化。
