This repository contains Python code replicating theDynamic DEA Slack-Based Model proposed by Tone & Tsutsui's (2010). The Dynamics SBM DEA is a DEA model widely used for analyzing the evolving structure of dynamic networks. This project aims to provide an open-source implementation for researchers and practitioners interested in understanding and applying the Dynamic SBM.

A brief summary of the Dynamic DEA Slack-Based model (Tone & Tsutsui's, 2010):

The SBM model is non-radial and can deal with inputs/outputs individually, contrary to the radial approaches that assume proportional changes in inputs/outputs. Furthermore, according to the characteristics of carry-overs, we classify them into four categories, i.e. desirable, undesirable, free and fixed. Desirable carry-overs correspond, for example, to profit carried forward and net earned surplus carried to the next term, while undesirable carry-overs include, for example, loss carried forward, bad debt and dead stock. Free and fixed carry-overs indicate, respectively, discretionary and non-discretionary ones.
