An Example Fuzzy Expert System

The problem this expert system addresses is supplemental feeding for range cows. The example is extremely simple and needs additional knowledge incorporated before it would be useful for developing actual range cow supplementation plans. However this example does demonstrate the mechanics of developing a fuzzy expert system. A mathematica notebook for the example is available.

Step 1 -- Define Fuzzy Sets

Step 2 -- Relate Observations to Fuzzy Sets

Step 3 -- Define Fuzzy Rules

Step 4 -- Evaluate Each Case for all Fuzzy Rules

Step 5 -- Combine Information from Rules

Step 6 -- Defuzzify Results
