Designing of expert system for troubleshooting diagnosis on Gas Chromatography GC-2010 by means of inference method

Gas Chromatography (GC) is used to analyze various products of volatile materials such natural gas, oils, pharmaceuticals, and foods. It is needed to control the quality of products till fulfill its requirements to be marketable. Therefore, maintenance is required to maintain the GC system running well. The expert system software for watering down the troubleshooting diagnosis on GC-2010 had been done by means of inference method. Based on the result of analysis, the probability of damage which often occurred are fluctuating pressure and high noise. The result of simulation show that the total time effectiveness using expert system software is 51.3% and the average step effectiveness to solve a problem in GC system is 21.5%.
