Special Indicators of Integrated Efficiency Assessment of Using the Root Crops Cutter

Abstract

Ensuring a stable feed base is one of the most important conditions for intensive livestock farming. Another necessary and obligatory condition is the use of modern methods of feed preparation with the use of highly efficient technical means. Evaluation of the effectiveness of the developed technical means should be carried out not by one indicator, but by a set of specific indicators combined into a complex criterion, taking into account the importance of all selected private indicators. (Research purpose) The research purpose is selecting the most important specific indicators for a comprehensive assessment of the effectiveness of the root crops cutter based on the analysis of scientific papers and the functioning of technical means used for the cutting of root crops for cattle feed. (Materials and methods) The methodological basis for the selection of indicators for a comprehensive effectiveness of the cutter was the effectiveness theory of the technical means. The initial material for determining the specific indicators of an efficiency assessment was their technical characteristics and quality indicators of the technological operation. (Results and discussion) Based on the analysis of research work and production experience, two key groups of indicators were identified for the effectiveness assessment of the cutter. They are the power for cutting – Nизм, labor costs per unit of cutted products – Зт, capacity of the cutter – Wч, operating time for failure – t0, time spent on the elimination of technological malfunctions – tтехнол, specific labor cost of maintenance tуд.ТО, level of juice loss Пс. It was proposed to determine the relative importance of each specific indicator by the method of expert evaluation. (Conclusions) Indicators for a comprehensive assessment of the efficiency of the use of root crop shredders are economic and quality. The economic indicators were attributed to the power costs for cutting root crops and labor costs during cutting; quality indicators include the productivity of the cutter per unit of time, operating time for failure, time spent on eliminating technological malfunctions, specific labor cost of the cutter maintenance and the level of juice losses.
