DEA 建模介紹

撰寫 DEA 各種模型的算法與建模流程的文章，目前包含以下模型：

• CRS(constant return to scale; input-oriented) ：固定規模報酬的模型

• VRS(variable return to scale; input-oriented) ：變動規模報酬的模型

• Network DEA：探討系統內部各階段的效率值

DEA 擴充函式

將 DEA 複雜的建模流程包裝成擴充函式，方便迅速針對問題進行建模與分析。

根據不同的主題，移動/下載對應的 Sub-folder (裡面包含擴充函式原始碼、資料(.csv)、以及範例(Jupyter Notebook Example))，便可以根據說明文章(Documentation)來學習操作。
