本研究依進口貨物於航空貨物集散站之作業及資訊流程，建立航空貨物進口作業流程網路，以解析性方法計算各航機貨物之作業時間，並構建貨物於各流程之延滯及擴散模式。另本研究擬訂依貨物價值安排作業順序、增加作業容量及改善作業方式三種延滯控制策略，以降低作業延滯時間及延滯成本。最後，以實際案例進行模式驗證及分析。結果顯示，愈接近空側之作業，受前一航班貨物所造成之推擠性延誤愈明顯，而愈接近下游之作業，受同航機貨物之推擠延誤愈嚴重。此研究結果可作為航空貨物集散站改善進口作業流程及擬訂控制策略之參考依據。

This study develops a network of cargo import process and information flows at an air cargo terminal and explores the causes and characteristics of delays in cargo processing. Using analytical methods, this research also constructs a process-delay and delay-propagation model and derives a process time evaluation algorithm. Delay-controlled strategies include changes in job sequencing and increases in process capacity at bottleneck operation zones, and process improvements are proposed for minimizing delays so as to achieve reductions in inventory costs. An example is employed to demonstrate the application and feasibility of the developed model and algorithm. Results of this study reveal that operations closer to the air side of the air cargo terminal have greater knock-on delays than start delays, while those in greater proximity to the land side have greater start delays than knock-on delays. Results of this study can serve as references for cargo terminal operators in improving cargo processing.
