Modelling of palm oil production using fuzzy expert system

The product ion of crude palm oil and palm kernel is a complex problem due to the inf luence of processing variables and environmental factors. These processing variables inf luence the amount of crude palm oil and palm kernel losses during processing. Instead of mathematical model, fuzzy logic approach provides a simpler and easier mechanism to describe the relat ionships between the processing variables and the amount of crude palm oil and palm kernel losses. In this study, four fuzzy expert system models were developed for each palm oil processing stat ion. An approximat ion of centre of gravity method for defuzzif icat ion is also proposed to enable the development of the model using Microsoft_Excel. For comparison purpose, the models were also developed using MATLAB_. Results obtained from the Excel model are found to be very close to the results f rom MATLAB.
