摘要
农产品冷链物流安全是促进农业产业化的关键.通过构建多维度农产品冷链物流安全预警指标体系,选取可拓关联方法对农产品冷链物流安全进行预警分析,建立农产品冷链物流安全物元模型,运用关联函数方法确定各预警指标权重,并结合算例分析进行验证.研究表明,该方法不仅可识别待预警对象所处安全等级及其发展趋势,还能对单指标或子系统进行安全状态分析,具有较强的可操作性.
The safety of agricultural products cold chain logistics is the key to realize agriculture industrialization .Multidimensional agricultural cold chain logistics security early warning index system is constructed in this article ,and the extension correlation method is selected to analyze agricultural cold chain logistics security and early warning .Among them ,the agricultural prod‐ucts cold chain logistics security matter‐element model is the foundation work .Furthermore ,the weights of early warning indicators are calculated by correlation function method .Lastly ,the in‐spection algorithm is practical through empirical analysis .Research show s that the method can not only recognize the object of early warning security level and its development trend but also can carry on the security status of single index or subsystems .Therefore ,the method is proved to have strong operability .
