Resumen:
Argentina is the third larger worldwide exporter of soybean. In the year 2003 the country was also the leader in the oil and flour production. The soy industry in Argentina has been systematically growing in the last few years. Despite the size and added value of this industry, soybeans processing plants are mostly operated based of experience and heuristics, without taking advantage of systematic tools for the decision making process in the plants operation. This paper presents the development of a preliminary mathematical model for optimal operation of a soybean processing plant. The plant products are soy oil and high protein soy flour apt for human consumption. The model was developed based on unit?s input-output relationships and efficiencies, specific resource consumptions, etc. It consists in the maximization of the plant annual profit, constrained by the plant mass and energy balances and resource capacities. The model was implemented in the GAMS (Generic Algebraic Modeling System) environment. Results are presented for a typical operation scenario, characterized by raw material and energy costs, product prices, etc. Plant model parameters are also studied to determine their influence on optimal plant oper
