Modification of Certainty Factor Method In Solving Expert System Problems

Abstract

The Certainty Factor method is used as a method of resolving the problem of certainty by calculating every possible value. The Certainty Factor method calculates the probable value of all the factors involved in a problem. The result of a certainty factor calculation is the result of a combination of the calculation of each factor. The combination stage of the certainty method is standard so that the calculation results will be greatly affected by the calculation of the first-factor value calculated. The certainty factor method is also known as the expert system solution method that has been used in many studies in diagnosing a problem. The influence of probability value of the first factor greatly influence the diagnosis result, therefore needed a research which discusses modifies at combination stage of method certainty factor.
