基于EJB的农业宏观决策支持系统研究

The Research of EJB_based Macro Agriculture Decision Support System

针对传统农业宏观决策支持系统的局限性,构筑了一个基于分布式组件技术下的农业宏观决策支持系统环境,提出了通过EJB组件建立农业宏观决策支持系统中评价模型的研究方案,实现了多个评价模型之间的协作和交互;提出了利用EJB组件建立集中式和分布式评价平台的方法,解决了地区性决策支持和全国性决策支持之间的矛盾;提出了利用EJB组件把评价模型发布Web Service的方法,从而为评价模型和数据共享问题提供了一种可行方案。

In the light of the limitation of traditional macro agriculture decision system, the pager constructs the environment of macro agriculture decision system based on and distribute component technique, it develops a project for evaluation model by EJBs in macro agriculture decision system, realizing the collaboration and interoperation; it develops a method of centralized and distributed platform based on EJBs , settling the conflict of decision for region and all; it develops a method of launching WebService of evaluation model. thus, it can be realized the evaluation model and share data.
