  1. Based on the historical space forecast data and corresponding actual data provided by a global semiconductor assembly and test company, the uncertainty of space planning was defined. during this analysis process, linear regression, grey prediction, neural network back propagation algorithm and confidence interval were applied, respectively, to define the uncertainty. compared with those methods, the confidence interval of historical space forecast error, calculated by mathematical statistics, was the reasonable method to define the space forecasting uncertainty

    本文從半導體工廠長期生產能力計劃的頂層即廠房生產面積的計劃展開,對一跨國半導體封裝測試公司提供的廠房生產面積的長期歷史預測數據以及對應的真實數據進行分析,採用線性回歸,灰預測,神經網路bp演算法,基於數理統計的置信區間的求解等方法分別定義廠房生產面積預測的不確定度,經多種方法的比較得出,基於數理統計方法求解出的生產面積歷史預測誤差置信區間能直觀清楚地標定不確定度。
