Expert System Based on Fuzzy Logic to Define the Production Process in the Coffee Industry

摘要

Coffee is the 7th largest agricultural crop in Mexico and occupies the 12th place as value generator. Cherry coffee production reaches about 1.3 million tons. This production equivalent to about 250 thousand tons of benefited coffee. Mexican exports reaches an average of 175 thousand tons, of which 90% are in grain and the rest are derivatives. The production process of coffee has not changed significantly over the years. In Mexico is common to select the type of process that coffee will be subject based on expert judgment, which causes problems in the absence of one. An expert system based on a fuzzy logic model was develop to support decision making on the type of production process considering variables such as weight, pellets, green aspect and the percentage of minor and major defects, all this information obtained from organoleptic analysis. A simulation model was used to test the validity of this expert system.
