摘要

以往發生重大災害事故時，衛生福利部會啟動區域緊急醫療應變中心，採取必要緊急措施。指揮中心在指派救護車後送傷患時，經常依照決策者或指揮官過去經驗所決定，此作法缺乏系統性最佳化分析，且可能造成誤判，導致延誤後送。因此，本研究以系統最佳化觀點，運用網路流動技巧定式救護車輛於時空中流動之情形，並配合數學規劃方法所構建一災後緊急醫療救護車派遣規劃模式。為評估模式正確性，本研究以桃園地區之相關資料及合理假設進行範例測試，並針對不同參數進行敏感度分析和方案分析，結果顯示本研究模式可作為決策者之規劃輔助工具。

When serious disasters occur, Ministry of Health and Welfare will initiate regional emergency medical operation center (REMOC) and take some necessary actions. The command center often assigned ambulances based on the decision maker's or commander's past experiences. However, this approach lacks a systematic optimization analysis. It may also cause delays to evacuate the casualties due to the incorrect judgment. Therefore, in this study, from the perspective of system optimization, we propose a model for dispatching emergency medical ambulances following a disaster. The proposed model is constructed by using the network flow technique, coupled with the mathematical programming method, to formulate the movement of ambulances in the dimensions of time and space. To evaluate the correctness of the model, a case study using the related data of Taoyuan City with reasonable assumptions is performed. A number of sensitivity/scenario analyses are conducted as well in the case study. The results demonstrate that the proposed model could be a planning support tool for the decision maker.
