Abstract

Most of researchers believe that GOAL PROGRAMMING and model making options are better techniques than LINEAR PROGRAMMING. That's why in this research the LINEAR PROGRAMMING model have been optimized and the comparison between them with attention to constraints and objectives of farmer have been done. The needed information for this research have been gathered from 120 farmers in Jahrom City through two stage cluster sampling randomly in the year 1385 (2006). The results well reveal that presenting common LINEAR PROGRAMMING model can only be useful about 12.81 percent in obtaining the goal. In almost optimized model, because of high yield due to consumption of production factors in spite of high fluctuation in their yield tomato and corn are still in the model and that's why most of farmers focus on composition change of four products including barley, melon, cotton and water melon. In addition, the results obtained from GOAL PROGRAMMING model show that in the time when goals have the same importance for managers and in the time when they do not have the same importance from gross profit point of view, the model is different. unde in the cases when the manager cat egorizes his goals based on priority, the yield of program is slightly higher as compared to when the goals have the same importance.
