The main goal of this article is to present optimization model for Moldova with multiple criteria, based on the input-output and computable general equilibrium approaches. Here demand and supply models are studied as integrated one composite input-output model. Such presentation carries on the fact that input-output models have dual presentation in demand and supply models. Based on this principle, computable general equilibrium model was examined. Simultaneously, balanced prices between demand and supply were determined. Multiple criteria non-linear programming is applied to balance between output and as well as the prices of demand and supply. Equilibrium is obtained as optimal solution among multiple criteria non-linear programming solutions.
