Food security is a key component of state security, and every country, especially some great powers in the world, has been paying more attention to national food security and its security system. This paper aimed at applying grey model to food security assessment in the province scale from statistical data and developing a prototype of food security assessment system in Liaoning Province. Firstly, the use of grey models is a novel concept in food security assessment and the principles of GM (1, 1) are explained systematically. Second, the framework of food security assessment is created based on three-tier architecture and the assessment system adopts the objectoriented development method and component technology. To show the validity and feasibility, the precision inspection is made under strict mathematical calculation. In the end, the realization of system results is presented partially. It is suggested that food security assessment based on grey model is an effective attempt to solve food security problems.
