| Abstract | ||
| Resource usage by crops pattern optimization is one of appropriate methods for development in agricultural sector. In this study, the objectives of efficiency maximization, costs and cash investments minimization, minimizing water consumption, minimize chemical fertilizer and minimize the use of chemical pesticides are achieved by using the conventional linear programming model (single-objective), definitive goal programming and a fuzzy goal method. The constraints of problem are availability of machines, the workforce, and the availability of monthly water needs of livestock forage. Information required for this study was obtained using a two-stage cluster sampling of 277 by questionnaires from Mahidasht plain villages. The results of this study show that the conventional linear programming model to achieve the goals of the study but there is no definite and fuzzy goal programming model is possible. Comparison results show that the fuzzy model and fuzzy deterministic planning model that will better achieve the more of objectives, as a fuzzy goal programming model, return of the program will increase 1.72% and the current cost, water consumer, chemical fertilizers and pesticides will decline 5, 3.87, 23.65, 11.51 % respectively.
