CHDS programmer and PhD student Zach Ward launches the development of an open source decision analytic modeling framework. Called Amua, from the Swahili word for “decide” or “solve”, the software is designed to be transparent, flexible, and accessible. The graphical user interface provides an intuitive way to develop and document models. Amua can also export models to other programming languages, allowing conceptual models to be separated from any particular implementation. As free software Amua can be used as a teaching tool, or by researchers around the world. Zach plans to begin alpha testing the software with CHDS colleagues in the next few months before publishing the first stable release.
