Foreplot is a 100% open source decision making platform using multi-criteria decision analysis (MCDA) methods. Foreplot can help you in ranking, prioritizing or choosing from among alternatives. It will help you structure multiple criteria or attributes into a hierarchy of decision criteria.

Foreplot currently implements 3 comparison methods:

• Analytic Hierachy Process (AHP) Wikipedia article on AHP
• Multi-attribute global inference of quality (MAGIQ) Wikipedia article on MAGIQ
• Direct / Simple Multi-Attribute Rating Technique (SMART) method

Demo site

Demo site is hosted on Heroku:

Built With

Back end:

• Ruby on Rails — This project is a Rails app.
• PostgreSQL — The main data store is in Postgres.

Front end:

• D3.js — Visualization charts.
• jQuery and jQuery UI — User interface

This project v. Foreplot.com (now defunct)

This open source project is a rewrite of the old Foreplot.com website. Although the user-interface is almost the same. The original Foreplot.com used MongoDB as a NoSQL data store, while this project uses PostgreSQL database. This alone requires fundamental change in model design. Only 3 comparison methods are implemented, and proprietary analysis methods are not implemented.

Currently, this project only does not implement group decision, only single decision maker is supported.

Note to old Foreplot.com users:

If you have old archives of articles, there is no feature to import it since the underlying database and formats are entirely different. You should be able to key in the input data (only 1 decision maker is supported), and only using the supported comparison methods.

Development

• I consider this an alpha version. There are still issues with the current release.
• Planned features include group decision making process, more visualization and analysis methods.

Contributing

Foreplot is 100% free and open source. I'm hoping that it will attract people to contribute to the development of this project. I accepts contribution from the public – including you!
