Abstract : Indoor vegetable production, or production in greenhouses enables year-round production, the combined off-season production, greater control of diseases and pests, but also significantly greater production value compared to open field crop production. The aim of this paper is to determine such a structure of vegetable production in greenhouses that will realize the maximum financial result considering various biotechnological, production, technological and market constraints. In this context, model for optimization of vegetable production structure in greenhouses was formulated, and at the same time, model analysis and model solving was made using the method of linear programming and the software package "LINDO". Model was analyzed in three variants, depending on the selected optimality criterion: maximization of net income (variant I), maximization of economics of production (variant II), minimum deviation from the extreme values (variant III). The results show the optimal sowing - planting structure for all three variants of defined model; the participation of certain groups of crops in the overall sowing - planting structure; the required number of working hours in the observed months of working peaks; that variant I achieves the highest net income for defined limiting conditions (4.216.867 din); that variant II achieves the highest economics of production (2,25), while variant I and variant III generate the same economics of production (2,20).Moreover, variant I realized the greatest value ofproduction (7.080.300 din), but also the highest variable (2.863.433 din) and total costs (3.263.433 din). Published data of various experimental paperworks were used for this analysis, as well as data from the accounting records of the farms and data of Statistical Office of the Republic of Serbia.
