LOGIKA FUZZY METODE MAMDANI DALAM SISTEM KEPUTUSAN FUZZY PRODUKSI MENGGUNAKAN MATLAB

The uncertainty of production system can be caused by stock uncertainty. The uncertainty problems can be solved by fuzzy logic using fuzzy inference system Mamdani method. The algorithm of fuzzy inference system is as follows: analysis of input-output, determining the variables of input-output, fuzzyfication for determining of the fuzzy sets, determining of rules, and defuzzyfication. The algorithm is implemented in Matlab7. The amount of daily production is determined by centroid method. For Wendnesday, by entering the variable demand of 4,000 packaging and packaging inventory number is 300, then resulted the amount of production of 4,200 packaging. The certainty of production system can be obtained from uncertainty amounts of demand and stock by using Fuzzy Logic Mamdani Method.
