Research on Grain System Evaluation Based on Fuzzy Evaluation System and GM(1,1) Method

With the development of the world, the current food problem has increasingly become the focus of international attention. Even today, in times of peace, the global food system is unstable. Part of the reason for these instability is our current global system of large-scale national and international food producers and distributors. In this paper, the relevant indexes of the relevant food system are collected, and a new food system evaluation system is established by using the mathematical model, and the optimization, discussion and analysis are carried out. In this paper, a new grain evaluation system is established by using fuzzy comprehensive evaluation method, and taking China as an example, the current natural and human factors in China are given and calculated, and finally get 70.64 points. Finally, it is found that China can realize the optimization of its food system only when the human development index reaches the United States today, and then understood by the grey prediction model, China will not be able to achieve it until 2041 20 years later.
