Research on Food System Evaluation Model Based on TOPSIS Improved Analytic Hierarchy Process

Abstract

At present, the shortcomings of the current global food system which focuses on efficiency and profitability have brought about enormous perplexity. Together with its instability, social problems related to the environment, livelihoods or politics resulting from its lacking of consideration for equity and sustainability have attracted extensive attention. We establish the evaluation model of food system by AHP and TOPSIS. We selected efficiency, profitability, equity and sustainability as four indexes at the criterion layer and 10 indicators at the scheme layer. It is concluded that the food system scores of all countries have been steadily increasing from 2010 to 2020 by processing data with TOPSIS.
