摘要


TFT-LCD ( Thin Film Transistor-Liquid Crystal Display;TFT-LCD)產業為台灣兩兆雙星之ㄧ,在2007~2009年因金融風暴因素造成消費大幅迅速衰退,到2010年因各國政府採取擴張的貨幣政策使得景氣緩步回升,而TFT-LCD的需求也深受擴張政策影響,尤其是中國政府的補助政策影響大尺寸銷售最大,所以在全球化狀況下,產品銷售不只是受到國內環境因素,也受到國外各國的環境因素之影響,目前國內TFT-LCD銷售預測模型,大多以國內環境因素及生產產值為考量,而較少針對國外主要外銷及消費國環境因素。 本研究以國內知名跨國際的TFT-LCD製造公司大尺寸銷售量為例,共分四部份;首先針對消費及終端產品生產國的景氣領先指標綜合指數,及國內景氣領先指標、消費相關指標蒐集因子資料並分類;第二部份以分類之全因子,進行迴歸分析變數關聯性及簡化變數;第三以倒傳遞類神經網路為主體,進行各種因子變數分類對銷售量之預測,並與傳統多元迴歸分析對比;最後,將上述各種組合預測結果,進行平均絕對百分比誤差法(MAPE)、誤差均方根差(RMSE)與平均絕對偏差(MAD)之衡量指標比較,並輔以迴歸分析確認組合性變數的關聯。透過本研究整理結果作為跨國際公司的銷售預測應考量的環境因子及時間因素建議。

並列摘要


TFT-LCD (Thin Film Transistor-Liquid Crystal Display) industry is the Two Trillion Twin Stars of Taiwan.The global financial crisis has made consumption to decline from 2007 to 2009.The economy slowly recovered as countries have expansionary monetary policy in 2010.The demand affected by the policy of expansion for TFT-LCD.In particular, the subsidy policy of the Chinese government was the greatest impact.In the globalization,the productions sale not to be affected the domestic environmental factor,also receives overseas various countries' influence of the environmental factor.At present, TFT-LCD sales mostly take into domestic environment and production value factors in the prediction model.It less take into the sale main export and consumption of the country of environmental factor. The research is divided into three major phases based on the data collected from a famous TFT-LCD manufacturer in Taiwan.(1) To collect booming leading index for expenses’ country and domestic booming leading target.(2) The complete factor combination carry on the regression analysis variable relatedness and the simplified variable. (3)These factors will input the BPN(Back-Propagation Neural Network) and Multiple Regression model to analysis.Finally, MAPE, MAD and RMSE are used to compare models.The results indicate which the model has the best prediction ability compared to others.It is recommended the cross international company for business to apply in sales forecasting.
