## 9 Conclusions  
In the course of this study, we developed the following method for optimizing the formation of the MTF of an agricultural enterprise for its subsequent use in field farming.  
* At the first stage of this method, primary data on the functioning of the MTF of the agricultural enterprise are collected and processed. For example, calculations of the planned production rates and the cost of implementation of the MTF must be carried out. In addition, the permissible values of exogenous variables must be determined. In particular, the agro-terms of mechanized field work, and the available number of tractors and combines in the MTF are determined. It should be emphasized that with the exception of one loader and one combine harvester in the agricultural enterprise \"Novy Dvor-Agro\", all the machinery and equipment on both farms are fully involved in the production process. Therefore, it is necessary to update the existing equipment in time when 100% wear is reached.
* At the second stage, in order to develop reserves for improving efficiency on the basis of the economic and mathematical models presented above, the composition and structure of the MTF, as well as the schedule of its work during the planning period, are optimized. In the absence of an initial plan in the form of a current schedule for the work of the MTF, a heuristic algorithm for building an initial plan suitable for launching a model complex can be applied at this stage.
* At the third stage, a numerical solution obtained in the GAMS system is brought into the line with the integer requirement and checked for compliance with the constraints of the mathematical model. If necessary, the optimal plan is adjusted.
* At the fourth stage, on the basis of the modified optimal plan, a schedule for the implementation of the MT works for the planning period is constructed.
* The fifth stage consists of a comparison of the total costs for the agricultural operations of the MTF of the enterprise before and after optimization, with a breakdown into separate cost elements. The economic effect of the introduction of the proposed algorithm is estimated.  
The developed method for optimizing the formation and use of the MTF of an agricultural enterprise in field cultivation that is proposed within the framework of this study can be successfully applied in managing the agro-industrial complex at the micro-level and meso-level. The process enables decision makers to optimize the schedule of the MTF for a given period, to draw up an optimal plan for the purchase of new equipment in terms of their total costs, and to identify unused equipment. The proposed model and algorithm can improve the comparative efficiency in the use of an enterprise's MTF. Optimization ensures a reduction in the cost of material resources, resulting in increased profitability of agricultural production.
