Application of Fuzzy Multi-objective Linear Programming Model for Determining Optimal Cultivation Pattern of Different Varieties of Rice in Paddies Babolsar

In this paper important quantitative and qualitative indices for determining cultivation pattern of different varieties of rice including Khazar, Binaam, Tarom as well as 10 basic indices of rice farming have been considered. To do this, the opinion and experience of both farmers and experts have been used. The indices are scaled (weighted) through Fuzzy analytic hierarchy process in-Extent Analysis Method (EA) of Chang- in which the numbers used are Fuzzy triangular. Ranking weights entered linear programming model in order to get the best cultivation pattern of city paddies Babolsar in 1390. The main constraints were land, labor, capital, water, chemical fertilizer, tractor and pesticide. The results of LP model suggest cultivation of both Binaam (10200 hectare) and Tarom varieties (4200 hectare) while the mixture of Fuzzy analytic hierarchy and linear programming model recommends the cultivation of Khazar -10200 hectare-instead of Binaam variety besides Tarom variety in cultivation pattern which has higher benefit.
