Since the correct selection and adaptation of the tractor to the equipment and vice versa and considering the justifying level of ownership in the agricultural economy and its efficiency and timely performance of agricultural operations play an important role, there is a need for great care and sensitivity in this matter. A farm manager or farmer will achieve complete success in applying mechanization when they achieve the highest degree of agricultural mechanization according to the working time with the minimum number of agricultural machines and the least amount of power. In this research, a decision-making computer system was designed and developed using Visual Basic programming language. This system is able to use effective and overlapping evaluation criteria to select the appropriate crop for the available power source and vice versa according to the crop calendar to perform mechanized operations. Finally, this system was used to measure flexibility and efficiency in a paddy field with an area of 8.6 hectares. The advantages of using the decision-making system developed in the study project include reduced consulting costs, elimination of personal preferences and reliance on technical and real knowledge, increased work efficiency, and prevention of energy loss, capital and over-compaction of farm soil. In addition, this system can be used for management, training and research purposes in the field of agricultural machinery.
