 # Statement of need
 
+Although the ARIO model has been used in multiple studies, and several extensions
+exists, only a few implementation of the model or similar ones are openly available.
+We found the following existing implementations:
+- A python implementation of MRIA is available on the [personal GitHub
+repository of E. Koks](https://github.com/ElcoK/MRIA) (from [@koks-2016-multir-impac]).
+- [C. Colon repository](https://github.com/ccolon/disrupt-supply-chain-model/) holds
+a python implementation of Disrupt Supply Chain in [@colon-2020-critic-analy].
+- A C++ implementation of the Acclimate model from [@otto-2017-model-loss]
+is available [here](https://github.com/acclimate/acclimate).
+- A Matlab implementation of C. Shughrue's model developed in

+are both available on [D. Wang personal repository](https://github.com/DaopingW/)
+
+None of these implementation offers a comprehensive documentation, and most are
+specific to the case study there were used for. The purpose of `BoARIO` is to fill
+this gap of an "generic, documented, easy to use and extend" indirect impact
+assessment model.
