A Research On Decision Support System For Agriculture Structure Adjustment At County Level

Contraposing the status of agriculture structure adjustment and information technology.considering the lack of current information technology's research on agriculture structure adjustment,the paper applied decision support system to agriculture structure adjustment at county level,mainly using forecast model and linear programming model to support agriculture structure adjustment,and brought forward a new method of model developing.The paper analyzed agriculture structure adjustment's essentiality.its central problems currently.and the status of agriculture production, introduced decision support system's conception,theory and technlogy,summarized decision support system's research history for agriculture at home and abroad. Simply introduced and compared some technologies applied:Object-Oriented Software Engineering,Unified Modeling Language,Web Application Software Developing,.NET,Decision Support System's Modeling Technology.On the basis of these technologies, it took administrative department of agriculture at county level and common farmers as application objects.completed decision support system's analysis.design and development for agriculture structure adjustment at county level,did a case study in crop cultivation in Hua county of Henan province to validate.analyze and compute the datum.The paper mainly expatiated three key problems and their solutions during the system developing phase:using ADO.NET to access database.implementing graph report forms by ChartDirector,ASP.NET referring to Matlab's COM.Particularly,that ASP.NET referring to Matlab's COM to implement models' development is the paper's focus of innovation.The research referred to multi-subject knowledge including System Science.Ecnomics, Operational Research,Computer Science,Agriculture,etc.Its main outcome was that summarizing agriculture structure adjustment's status, principles,problems in China in theory;implementing a decision support system based on module and Web technically.providing the deep research on agriculture structure adjustment at county level with a prototype frame.Additionally, it brought forward a new method to implement decision support system's model:ASP.NET using Matlab's powerful function by referring to its COM which came true in practice successfully.This method could reduce model development's difficulty and programming's workload efficiently.laying a good technology foundation for decision support system's model development and extension.
