The establishment of a coordinated food system is the basis for supporting economic development, protecting the natural environment and maintaining social achievements. In our paper, three countries with large grain output and rich grain system -- the United States, India and Brazil were selected as the research objects. Firstly, the EPES comprehensive evaluation model of grain system based on principal component analysis and analytic hierarchy process was established to realize the comprehensive evaluation of four subsystems of grain system at three national scales. The sensitivity analysis of the consumer price index in the evaluation model is also carried out.
