Problem. Currently a steady growth of mini-excavator market is observed in Ukraine. Due to the compactness and versatility in exploitation mini-excavators are used for carrying out building, municipal, road and other types of works. However, in modern conditions there is a problem of the reasonable choice of a mini-excavator using the criteria of necessary functionality and economic efficiency. This problem can be solved only on the basis of analysis of the data array on machine samples available on the market using modern information technology. The aim of the work is to increase the efficiency for the process of choosing a mini-excavator by developing a multi-criteria choosing model, which will reduce the time of scientifically grounded selection. Methodology. Utility theory methods and multi-criteria decision-making methods are used to select mini-excavators according to many functional and cost criteria. The results obtained. The main parameters of mini-excavators that impact their choice are considered. A model for choosing a mini-excavator based on many functional and cost criteria and limitations has been developed. The model developed belongs to the problems of multi-criteria linear discrete programming with Boolean variables. Practical value. The use of the developed model for choosing a mini-excavator based on many functional and cost criteria will allow to make a scientifically grounded choice.
