摘要
Abstract
The Internet platform and the food system are interconnected and a comprehensive evaluation index system based on the Internet plus dynamic model is constructed.The system uses Hadoop to process big data,and uses different algorithms to evaluate the four first level indicators of sustainability,equity,efficiency and profitability.AHP is used to calculate the comprehen-sive evaluation score.Linear regression models are established for the influencing factors of the first level indicators and the signifi-cance is judged.In order to improve and predict the system when the target value of regression model variable can be changed,the ordinary differential equation model dx/dt=-k(x-A)is established by dynamic model and the special solution is obtained.It evalu-ates and visualizes the food system of China and Australia by the evaluation system.The results show that the optimized evaluation system can analyze the main factors that determine food security through the development trend of indicators,get the overall evalua-tion and avoid the situation that the overall level covers individual indicators,and can use the characteristics of the Internet to dy-namically update the data sets and model results.关键词
