Testing: Certainty Factor Calculation CF(A) = CF(G(25)) + CF(G(26))) * [1-CF(G(25))] = 0,5 + 0,6* [1 – 0,5] = 0,8 (4.1) CF(B) = CF(G(2)) + CF(A) * [1-CF(G(2))])] = 0,6+ 0,8 * [1 – 0,6] = 0,92 (4.2) CF(C) = CF(G(3)) + CF(B) * [1-CF(G(3))])] = 0,8+ 0,92 * [1 – 0,8] = 0,984 (4.3) CF(D) = CF(G(5)) + CF(C) * [1-CF(G(5))])] = 0,8+ 0,984 * [1 – 0,8] = 0,9968 (4.4) (4.4) * 100 = 99,68% (4.5)
Testing: User Acceptance Test No. Category Total Average Score Satisfaction Level 1. Interface 3.40 Very Good 2. Functionality 3.07 Very Good 3. User Friendly 3.15 Very Good Level of satisfaction: 3.1 – 4.0 = Very Good 2.1 – 3.0 = Good 1.1 – 2.0 = Fair 0.1 – 1.0 = Poor
Conclusion Expert System application is : • success to be provided and presented the full article and the curriculum steps for parents, and parents can do consultation on the application with fees are relatively inexpensive and do not require long time • success to provide value to the accuracy of the diagnosis in accordance to calculation certainty factor method. • success to be built with the PHP programming language and to be hosted in the www.esdas.windyaz.com website.
