Abstract: The purposes, principles and bases of developing an IMOPM of agricultural production and agricultural engineering development in Inner Mongolia are discussed. Then, the IMOPM is developed on the basis of various separated industry zone divisions and plannings. The comparison of characteristics and limitations of LP (Linear Programming) and MOP (Multiple Objective Programming) application in agricultural production, and the decomposition-optimization technology of large LP agricultural production model are also studied. The discussed method can be used as reference for similar planning work in other regions and provinces.
