This would be most useful for automatic "level-of-detail" generation, but this kind of solution is not commonly used as it lacks artist control. There are a number of simplification programs that run in the context of various art tools that might be more robust.

The robust solution is to use something like the SimplyGon product to simplify the model within the context of an art tool: http://www.donyalabs.com/
