Determining the influence variables in the pork price, based on expert systems

Abstract

The meat industry is the most important economic activity in the agro-food sector. Globally, the pork meat is the most consumed, beating the poultry. The price of raw materials of natural type is based on reference quotes made from wholesale source products, and those are general prices. The contract wholesales publishes a price every week of the year. In this paper we studied the elements or circumstances, which we have named variables, that influence the price of pork and the quantification of each one’s weight (degree of influence) has on the price quoted. This study is based in fuzzy logic through the use of the theory of expertons developed by Kaufmann (1987) and Kaufmann and Gil Aluja (1993).
