VisionEval is a programming framework for disaggregate strategic planning models. Background information is available on the project Website, including the System Design. This site is focused on management of the collaborative effort.
Start with the Getting Started page, the description of the VE Models, and the VERPAT Tutorial, VERSPM Tutorial, and the VERSPM Training. Model developers should also review the Developer Orientation page.
When considering contributing to VisionEval, start by reviewing the Goals and Objectives page and the Contribution Review Criteria. In addition, the Working Together page describes how we use version control and our test system, and the Automated Testing describes our test setup in more detail. Our Development Roadmap should also be reviewed.
Contributions are currently being reviewed by the Pilot Review Team.
Modules & Packages
Modules perform individual tasks and are the fundamental building blocks of VisionEval code (e.g., create households). They perform single or multiple (sub-module) functions. Packages are logically related combinations of one or more modules organized into libraries, as a way to distribute the VisionEval code (e.g. HH synthesis including location, income, age, etc.). Each module is assigned to a package.
Models consist of a set sequence of modules called in a run script. A model is further customized for a local community by the set of data used from the datastore.
Graphical User Interface and Scenario Viewer
A GUI and scenario viewer (outputs visualizer) that works for the VE models has also been developed. The GUI and scenario viewer support setting up, running, and viewing multiple scenarios.
