需求預測(Demand Forecasting)是指通過分析曆史數據、市場趨勢和外部變量,系統性地預估未來某一時期産品或服務需求量的過程。其核心目标是幫助企業優化資源配置、減少庫存成本并制定科學的生産計劃。
從方法論來看,需求預測主要包含三類技術路徑:
在實踐應用中,沃爾瑪通過需求預測系統實現了98.3%的庫存周轉準确率,該系統整合了天氣數據、社交媒體輿情等300+變量(哈佛商業評論案例庫)。制造業領域,豐田汽車的JIT(準時制生産)體系每年節省超2.6億美元倉儲成本,其底層邏輯正是精準的需求預測(MIT斯隆管理學院運營分析報告)。
Demand forecasting(需求預測)是指通過分析曆史數據、市場趨勢和其他相關因素,對未來一段時間内産品或服務需求量的預估過程。它是企業運營和戰略規劃的核心工具,廣泛應用于供應鍊管理、庫存控制、生産計劃等領域。
目的
幫助企業提前預判市場需求,優化資源分配(如原材料采購、人力資源安排),減少庫存積壓或短缺風險,提升客戶滿意度。
主要方法

簡單移動平均法的公式為:
$$
Ft = frac{D{t-1} + D{t-2} + dots + D{t-n}}{n}
$$
其中,( F_t )是第( t )期的預測值,( D )為曆史實際需求,( n )為周期數。
有效的需求預測可降低運營成本約10-30%(部分研究數據),尤其在全球化供應鍊中,精準預測能顯著增強企業抗風險能力。
