行動代理者 (Mobile agent) 是可在一異質網路系統 (Heterogeneous network system) 內從一主機 (Host) 遷移 (Migrate) 至另一主機併和其他代理者及分散資源系統(Distributed resources) 溝通及交互作用(Interact)之軟體程式。它們特別適合用來發展分散式及網路上的應用系統。而行動計算 (Mobile computing)在近年來漸漸得到更多的重視，因為更多的專業人仕發覺了使用行動平台 (Mobile platform)、如行動電腦 (Mobile computer) 及個人資料擷取器 (PDA) 以無線網路連接上有線網路後，可隨時隨地、了無限制擷取廣大而分散在各處的資訊的好處。
當行動代理者在網路上漫遊、運算並收集資料，經過一些服務站(Service stations)執行後，可能會攜帶龐大的中間結果(intermediate results)在網路上漫遊，而這些中間結果可能只在行動代理者的最後目的地或漫遊過程中的某一服務站才會用到，但卻因此造成在每一代理者服務站上都需花費大量的資源來處理行動代理者所攜帶的龐大中間結果。另外、行動代理者攜帶大量資料在網路上漫遊，也增添了行動代理者資料安全上的問題，故本論文提出一物流系統 (Logistic System) 架構，並將其與MACE系統整合起來解決上述發生的問題。此物流系統將幫助行動代理者來處理、寄送其中間的資料結果到預定的目的地，使行動代理者無須攜帶大量的中間結果資料在網路中移動。

Mobile agents are software program that can move from host to host and interact with other agents and distributed resources in a heterogeneous network. They are therefore particularly effective for developing distributed application. Mobile computing is also gaining more and more popularity in the recent years as professionals discover the benefits of being able to connect to the vast of distributed information resource at all time without any spatial constraints.
When mobile agents are serviced by some service stations, they maybe migrate with an amount of intermediate results that just be needed in mobile agent’s destination or some of the service stations. And in each service station that mobile agents have migrated must cost a large time and resources to process mobile agents in receiving and interpreting agent’s content. Therefore, this paper presents a Logistic System (LS) Architecture and integrates with MACE (Mobile Agent Carrier Environment) to resolve the above problems.
