The author was a CIA analyst who evidently collected various decision tools over his career at the CIA. With weighted ranking, there was a reason that it used the exponential weighting, but I can’t remember any reasons for that. Probably someone with statistical background could point out the reason quickly. I learned the method with exponential weighting from an ACM meeting that dealt with software estimation and decision making, long time ago.
Hope that the blog helps.

I just did a weighted ranking spreadsheet for a CMMI Decision Analysis Resolution concerning choosing new products for our software version control and issue tracking. Someone else had set up our first DAR, and I questioned the validity of the method from the beginning. No analysis was done to validate the method, and no precidence could be cited. I doubt that better methods will ultimately change the outcome, but I’m going to try to understand better what you have presented here and at least check it against our result.
