Abstract. The paper presents mathematical model of complex evaluation of the quality of production with optimizing indicators of crop growing. Multicriterion model is reduced to the problem of optimizing with the predetermined target function which considers almost all parameters of the prodution quality. The model takes into account limits of modifications of quality characteristics of production by introducing the indis-tinct description of the quality characteristics of produc-tions. The model was developed on the example of evaluating quality of the barley grain.
Key words: target function, fuzzy restriction, vector-optimizing model.
