The Research Of Agricultural Production Structure Optimization Decision Support System

With the advancement of urbanization, the structure of agriculture production faced new challenges due to the decrease of cultivated land area and the problem of irrational crop production structure. In order to promote the adjustment of agriculture production structure, the macroscopic programming mathematical model and DSS of agricultural production structure optimization were developed based on the theory and technology of decision support system, which could provide support for decision making of agricultural production. The main work of this paper was as follows:1. Investigated the situation of domestic and foreign agriculture decision support system by searching some relevant literature, the problems of agriculture production structure in Hangzhou were analyzed and summarized, and the main objectives of this article were determined.2. Researched on the theoretical basis of agricultural production structure optimization decision support system. The theory of decision support system and the mixed- language programming based on MATLAB and JAVA were discussed in this paper to form a technology roadmap; the forecasting model, input-output analysis model and structural model were used to support the adjustment of agricultural production structure.3. According the characters of Hangzhou crop farming data, an optimized GOM(1,1) had been proposed based on Newton interpolation and compound trapezoid formula, which can fit decreasing sequence in the same direction and eliminate the error brought by the decreasing origin sequence in GM(1,1) model. At last, the proposed model was proved to be better than the original model through example analysis.4. The analysis and design of agricultural production structure optimization DSS. It took administrative department of agriculture and farmers as application objects and made full analysis of the requirement, then the system framework and detailed functions of each module were confirmed. On the basis of these work, a complete agricultural production structure optimization DSS was formed.5. The development and operation of the agricultural production structure optimization DSS. It’s well demonstrated the decision making of the a gricultural production structure optimization DSS by validating, analyzing, computing the system using the agricultural production data of Hangzhou.
