Abstract :
Wide Area Network (WAN), which is one of the widest geographic computer
networks that can cover between countries and between continents. Along with
the very rapid development of technology, the difficulty in diagnosing WAN
network damage and it takes a long time now the field of communication
networks has used technology to help diagnose problems that appear on the WAN
network. Of course, the purpose of this research is to produce a website-based
expert system that is able to diagnose damage to the WAN network where the
damage can only be solved by an expert or expert in the field. The resulting
program is able to provide high accuracy results by using several methods and
an algorithm, the method and algorithm used in this research are the Pairwise
Comparison method to determine the weight of each existing criterion, the
similarity algorithm to calculate the similarity between training data with testing
data, and the Rule Based Reasoning method to solve problems based on
previously resolved problems, thus the resulting program is able to provide high
and precise results or accuracy based on data obtained from experts or expert
technicians in their fields which are stored on the basis knowledge system built.
