AN OPTIMAL GREY COMBINATORIAL FORECASTING MODEL FOR CORROSION OF GAS PIPILINES
输气管道腐蚀的最优灰色组合预测模型

Based on the study of unequal interval grey sequence forecasting,an optimal grey combinatorial forecasting model was established for the corrosion of gas pipelines.Firstly two unequal interval grey forecasting models with higher precision were established.Then the optimal combinatorial forecasting model was given by minimization method of error of model in the sense of least square to find the expression of weight of the above mentioned models.This model takes full advantages of effective information of com...
