The Particle Swarm Optimization Based Calculation Research on Agricultural Mechanization Contribution Rate

摘要

Firstly, the paper introduced the basic principles of Particle Swarm Optimization. Secondly, researched on agricultural mechanization contribution rate theory, established the calculation model of agricultural mechanization contribution rate. Given the solving-process of the model and took Particle Swarm Optimization to solve the unknown parameters in the model. Finally, used agricultural machinery input, agricultural labor force, and cultivated land area, effective irrigation area, chemical fertilizer as input and agricultural production as output and estimated agricultural mechanization contribution rate of Shandong Province, and achieved good results. From the calculated result can be proved that the model is scientific and feasible.
