物联网环境下农产品供应链风险源结构模型

Risk sources structure model of Agriproduct supply chain on internet of things

为分析物联网技术条件下农产品供应链风险状况,依据现有的物联网层次结构辨识农产品供应链的风险源,建立以感知层风险、传输层风险、应用层风险和其它风险为准则的物联网环境下农产品供应链的风险源层次结构模型。针对物联网环境下农产品供应链风险数据不足和风险因素的模糊性,采用三角模糊数描述专家判断语义信息,提出一种基于三角模糊数的物联网技术条件下农产品供应链的风险层次结构分析方法。进而通过一个算例对所提出的方法进行验证,结果表明,该方法可以用于物联网环境下农产品供应链风险源分析。

This paper aimed at analyzing the risk of agricultural supply chain with the Internet of Things（ IOT）technology.Based on the existing IOT technology hierarchical structure that was used to identify the risks of agricultural supply chain,a risks hierarchical structure model of IOT- enabled agricultural supply chain was set up.The model included the principle of the risks of perception layer,the risks of transmission layer,the risks of application layer and some other risks.Because of the deficient of the IOT- enabled agricultural risk data and risk factor ambiguity,triangular fuzzy number was used to describe expert judgment- semantic information,and then a hierarchical structure method proposed for the risks of IOT- enabled agricultural supply chain layer relaying on triangular fuzzy number.Finally,an example was used to verify the proposed method,and the result indicates the effectiveness of the method to analyze the risks of IOT- enabled agricultural supply chain. It showed that the method proposed can used to analyze risk of agricultural supply chain on internet of things.
