This is cool. It looks like this is a program for creating and evaluating a decision matrix:
https://en.wikipedia.org/wiki/Decision_matrix. This got me thinking about an idea for a similar tool, but catered to a specific domain, one that can be populated with data to help make the decision -- e.g., where to live, where to go to dinner, what kind of car to buy, etc. A decision where the options have known important criteria and quantifiable values, e.g. a decision about where to live has criteria like cost of living, crime rate, walk score, etc. Essentially, it would be like criteria filters you commonly see on shopping websites except it would let you rank those filtering criteria as well.
