Finding the most efficient machinery system for diverse farm structures being present nowadays would be of great importance. It is necessary to elaborate a comprehensive mechanization guide relating for all plant growing farms, which encourages agricultural production and contributes to establish basic principles of sustainable farming. The determination of the structure of a low-utilization-cost machinery park applicable for diversely sized farms turns economic information available on mechanization arable plant growing.
Development of mechanization planning methods is a demand claimed by the practice, since planning methods of previous years do not necessarily meet nowadays’ requirements. The problem can be solved by a planning method, which takes into consideration the present farm structure, the wide range of available machines and operational price level of power machines with different level of utilization. It should also be suitable for determination of investment-, utilization price and structure of machinery systems of low-utilization-cost machinery system consisting of power machines from diverse product lines and which can also be assigned to different company sizes.
The above aspects can be taken into account by means of a programming problem. Based on the literature it is obvious, that the programming problem is able to integrate the majority of the influencing factors and conditions of mechanization. With programming problem it is possible to model complicated mathematical interrelations, and the solution can be found with a computer program package.
The elaborated non-linear programming model is capable of planning machinery systems of farms having diverse sizes and production structure and determining the machine utilization cost and the structure of type of cost. As software, we used the widely known Excel program.
