Multicriterion evaluation of using machinery and resources of agricultural enterprise
Results are given from multicriterion evaluation of using machine-and-tractor fleet of an agricultural enterprise when choosing its optimal structure. By way of example of a model farm located in Novosibirsk Region, there was carried out a calculation of the machine-and-tractor fleet structure by using the method for looking through the options of annual complex of operations. To carry out multicriterion evaluation, the following indicators were selected: costs for purchasing machinery, the number of machine operators and direct operating costs. To take into account these three indicators when evaluating the efficiency of options, an additive criterion was selected. The objective function is formed by adding the normalized values of the particular criteria multiplied by the significance coefficients. Since the particular criteria have varied physical nature and accordingly different dimensions, then when forming a generalized index we operate with not “natural” criteria but their normalized values, i.e. each parameter varies from zero to one. In order to determine the generalized index, expert assessments are used. Experts in assigning significance coefficients are heads of agricultural enterprises. An option, the objective function of which is minimal, is considered to be optimal. It has been established that the selection based on several indicators (criteria) and priorities makes it possible to choose the best option of using machinery and resources for a particular agricultural enterprise. The proposed method for multicriterion evaluation of the machinery use options combines expert technical and economic approaches.
