一、基于R-GRA模型的指标体系量化优选

1. Quantitative Optimization of Indicator System Based on R-GRA Model

本节采用R-GRA模型对食品冷链物流运营系统风险预警指标体系进行优选，对初步建立的风险预警指标体系进行降维，以提高预警工作效率，降低预警工作成本。

In this section, the R-GRA (Rough Set-Grey Relational Analysis) model is adopted to optimize the risk early warning indicator system for the food cold chain logistics operation system. This process involves dimensionality reduction of the initially established risk early warning indicator system, aiming to enhance the efficiency of early warning work and reduce its costs.
