目的 探讨验证灰色模型在尘肺患病人数预测的应用效果。方法 利用该煤矿1996～1986年尘肺患病人数进行建模,并建立了数学模型X(I)=583e0.038(T-1)-452,作外推预测验证。结果该灰色预测模型的拟合程度较高,取得了较好的效果。结论灰色模型可应用于尘肺患病人数的预测。
Objective To explore the application of the gray model in predicting the number of pneumoconiosis patients. Methods The number of pneumoconiosis patients from 1996 to 1986 in the coal mine was modeled and the mathematical model X (I) = 583e0.038 (T-1) -452 was established for extrapolation. Results The gray prediction model has a higher fitting degree and achieved good results. Conclusion Gray model can be applied to predict the number of pneumoconiosis patients.
