The ix modeling platform

Key features of the ix modeling platform [2]

The ix modeling platform (ixmp) is a data warehouse for high-powered numerical scenario analysis. It is designed to provide an effective framework for integrated and cross-cutting analysis (hence the abbreviation ix).

The platform allows an efficient workflow between original input data sources and implementations of mathematical models, via application programming interfaces (API) with the scientific programming languages Python and R. The platform also includes an API with the mathematical programming software GAMS.

For the scientific reference, see Huppmann et al. (2019) [2].
