Determination of cultivation optimum pattern in farms with attention to risk and uncertainly conditions (An approach: interval linear programming)

For taking advantage of Mathematical Programming models in determination of cultivation optimum pattern in farms with attention to risk and uncertainly conditions and despite indefinite and indistinct information, new techniques of Fuzzy and Interval Programming can be used. In this research, with the use of Interval Linear Programming technique and with attention to statistics of previous tillage periods (1378- 1384), cultivation optimum pattern of farmable crops are being determined under risk condition and with the aid of indistinct data and Interval Logic. The case study in this research is a farm with 85 hectare area and chosen crops are: wheat, barley, corn, sun flower, sugar beet and potato. Results indicate that Interval Programming model recommends cultivation optimum pattern of wheat, barley and potato with attention to risk condition and constraints of production, also with endure more risk, land under cultivation of barley and potato show a decrease and an increase respectively and fanners will earn more profit consequently. The results of Mentioned model as well are nearer to real world conditions.
