物流中心績效評估： 以印尼港口集箱貨運站為例

Abstract

本論文以印尼港口集箱货運站為案利，探討物流中心的績效評估。基於案例現況特性和需求，我們探討在「最近可存放位置」(closest open location，COL)的存放策略下單一貨品存取任務所耗的平均加權移動距離，此加權移動距離同時考量在不同走道和作業下的移動特性，可做為物流中心的動態績效估計模型。同時我們就空間規劃(layout)現況加以改進，提出新的規劃方案;所提出的方案能有效改進物流中心的平均加權移動距離。

Warehouse function within Container freight station (CFS) in general can be described as freight forwarding facility. The basic processes that occur in the warehouse are receiving, put-away, picking, and delivery the cargo. Closest open location rule used for storing the cargo into the racking system. One way to estimate the performance of warehouse is by calculating the expected travelling time (distance) from the layout. In this study, we use the uniform approximation to obtain the value of probabilities and use weighted distance as a measure to determine the motion distance for each storage location. Further, the proposed layout will compare its performance based on these value.
