APPLICATION OF FUZZY GOAL PROGRAMMING TO DETERMINE THE OPTIMAL CULTIVATION CROPS MODEL

Purpose of study: According to the role and importance of farm management units, using mathematical programming models have an essential role in determining the optimal cultivation pattern. This study represents the theory and application of a fuzzy goal programming model to determine an optimal cultivation pattern considering different goals. Methodology: Analysis of the fuzzy goal programming model and applying it in the decision of optimal cultivation pattern in the Ferdowsi University farm has been shown in this study. Main Findings: The results indicate that making flexibility in model coefficients - because of deficiency in information- with the fuzzy idea, remove this deficiency extremely, and conditions of cultivation pattern relatively improve, then inputs and sources are applied optimally. Implications: This study expects to help farmers and agriculture officials to decide better agricultural policies and practices. Novelty: This study is done at the research farm of agriculture faculty at Ferdowsi University, and the software WinQsb was used
