  • 供應商管理庫存模式(Vendor-Managed Inventory, VMI)提供賣方一套可快速迎合客戶需求並大幅縮短供貨前置時間的解決方案,但亦使得賣方承擔比以往更多的庫存成本與風險,賣方若能採用一套適用於供應商管理庫存模式之補貨策略,將能幫助賣方降低存貨壓力並提高補貨績效。本研究以賣方角度出發,使用Excel VBA建構一符合供應商管理庫存情境之模擬模式,以離散事件模擬與實驗設計分析方法,考量需求型態與變異、預測偏差、訂單凍結以及配送前置時間長度等環境因素,並以具Trade-off特性之平均存貨量與服務水準作為績效指標,探討在一單買方、單賣方的流線序列式供應鏈結構下,再訂購點(ROP)模式、物料需求規劃(MRP)與預測向前補貨策略(FFR)應用於供應商管理庫存模式之適用性與績效表現,並進一步針對績效表現較佳的預測向前補貨策略進行因子顯著性分析,最後以實務歷史需求數據驗證在供應商管理庫存模式下,預測向前補貨策略(FFR)確實比物料需求規劃(MRP)及再訂購點模式(ROP)有較佳的績效表現。
