Design of sustainable intelligent food information system through computer dynamic system model

ABSTRACT

Since COVID-19, the already fragile food system has become even more overburdened, and food security has become an urgent issue. Due to the excessive pursuit of efficiency and profit, the food system in the past has created various problems, the most prominent problem is the inability to find a balance between profit and ecological environment. Therefore, this article focuses on how to build a model that includes both aspects. In order to analyse the existing food system and introduce new ones, firstly, divide the food system into four subsystems of profitability, efficiency, sustainability, and equity, and set up several secondary indicators under each subsystem, and select appropriate countries as samples. Use the AHP, EWM, and CEM to calculate the corresponding index of each subsystem to form a new comprehensive evaluation model for the food system. © 2021 ACM.
