In this study, due to the necessity of targeted subsidies to the need for supportive policies on food security of vulnerable and detailed cost data - household income in 1388 and mathematical programming techniques (MGA), the demand system is almost ideal (AIDS) and compensating variation (CV) was used.In this study, basket of food has been so favorable that, while fine for standard amounts of nutrients, the budget confirmed a household medicine community as well as it has been applied. In the next step the main group of edible materials which had highest share in household costs have been introduced oral material and after estimating these groups demand functions by approximated almost Ideal demand system and method of regression separate appearance patterns (SUR) demand functions coefficients were obtained. Then using the same elasticity values of the demand analysis, spontaneous, and introduces the crossover has been calculated and the results are used to estimate the effects on welfare. It is notable that goal of this study was to focus on the provision of food security is vulnerable strata, using economic estimates of damage to households that have been introduced in this regard and comparison of effects of welfare changes in some price of major household goods, edible basket, vulnerable households as community has been defining the target and finally, with the emphasis on the necessity of identification of that society, necessary credits to support of optimal shopping free get into account premises Of different goods have been introduced in scenarios price is achieved.
