Abstract

The invention provides an agricultural product safety evaluation method and system based on risk entropy, and the method comprises the steps: constructing a monitoring matrix, and preprocessing the monitoring matrix to obtain a sample matrix; constructing a judgment matrix, and converting the sample matrix into a risk matrix based on the judgment matrix; splitting the risk matrix into a pluralityof sub-matrixes according to varieties, converting each sub-matrix into a risk entropy vector of each variety according to a risk entropy method, and longitudinally splicing the risk entropy vectors of all the varieties to obtain a risk entropy matrix; calculating the weight of each safety index based on the risk entropy matrix; and calculating a safety evaluation index of each variety based on the risk entropy vector of each variety and the weight of each safety index, thereby performing safety evaluation on the agricultural product based on the safety evaluation index of each variety of theagricultural product. The agricultural product safety risk assessment key technical problems of multi-source risk monitoring data fusion, high sparsity monitoring data conversion and utilization, macroscopic quantitative assessment and risk sorting can be effectively solved.

Description

technical field [0001] This application relates to the technical field of risk assessment of agricultural product quality and safety, in particular to a method and system for evaluating the safety of agricultural products based on risk entropy. Background technique [0002] Safety evaluation is one of the important technical means to ensure the food safety of agricultural products, and its evaluation results are an important scientific basis for risk supervision and decision-making. For a long time, limited by the inconsistency of monitoring data structure obtained by different monitoring work, the high degree of sparsity of monitoring data, etc., the utilization rate of multi-source data fusion is low, the mining and utilization rate of effective information of large-scale monitoring data is not high, and the security evaluation The work has long relied on qualitative evaluation methods such as "pass rate" and "exceeding standard rate". Risk evaluation and its related risk ...
