AHP and ExpertChoice

I propose to discuss, share ideas, etc. on using Analytical Hierarchy Process(AHP) and AHP-tools like Expert Choice or Decision Lens.

Here is an an example of an AHP evaluation:

 There is a decision to be made - Where to go for vacation?.
 There are criteria for making that decision - Scenery and Nightlife
 There are options available - Las Vegas and Yellowstone Park
 We can compare the importance of the criteria
   Scenery is more important than Nightlife
 Each option can be compared relative to each criteria
   With regard to Scenery, Yellowstone is better than Las Vegas
   With regard to Nightlife, Yellowstone is worse than Las Vegas
 We can then organize the comparisons of the criteria and comparisons of the options
 relative to the criteria to make a decision.
   Yellowstone Park is the better option by the logic that Yellowstone Park did 
   did better at one criteria and Las Vegas did better at the other but Yellowstone Park
   did better at the criteria that is more important.
