面向不确定数据的农产品追溯方法

针对现有追溯模型无法对可追溯单元的混合过程进行定量表示的缺陷,将不确定数据引入到追溯系统中,搭建了不确定数据追溯模型,提出了一个新的面向不确定数据追溯的查询方法,利用不确定数据的基本表示和查询方法,解决了多源追溯问题.基于模型,实现了追溯模型中的简单查询、节点评价和单节点异常推断功能.并且给出了多节点异常的求解方法.

Agricultural Products Traceability Method Using Uncertain Data

For the existing traceability model could not express the mixing process quantitatively, the uncertain data were brought into traceability system and the model based on these uncertain data was built up. A traceability inquiry method using uncertain data was proposed. The multi-source tracing problem was solved by using basic representation and inquiry method of uncertain data. The functions of simple inquiry, node evaluation and single node abnormal deduction were achieved based on the proposed model and the solving method of multi-node abnormal deduction was presented.
