주요(主要) 수요예측기법(需要豫測技法)에 의한 최적해(最適解)의 비교연구(比較硏究) - 시멘트제품(製品)의 경우(境遇)를 중심(中心)으로 -

The purpose of this paper is to compare several forecasting methods for the case of the cement product by the analysis of the forecasting data and by the study of major forecasting methods, which are the Trend Projection, Exponential Smoothing, and Multiple Regression Analysis. As a result, it is thought that the Multiple Regression Analysis is the optimal model for the case of the cement product. In addition, it is important to consider the future circumstances for forecasting, and to improve the level of the forecasting results through the precise analysis of the collected data.
