Development of a Model for Minimizing the Energy Costs of the Transport and Technological Complex

Purpose of the paper is using the criterion of minimum energy costs for development of a mathematical model for the designation of rational inter-consumption of direct-flow and transshipment technologies for the introduction of solid organic fertilizers and the distribution of the optimal storage of a mechanized corral from the intake of solid organic fertilizers. The methodological basis of the study is the criterion for selecting the optimal composition of machines is the minimum of the energy costs. The mathematical model of the complex on direct-flow and transshipment technologies is generally determined by the mathematical expectation of specific energy costs, which is the sum of mathematical expectations of energy costs in the mechanized unit on direct-flow technology, transportation of solid organic fertilizers in the field fertilizers by transshipment technology. The efficiency of mechanized units increases if trucks are included in them during the period of export of solid organic fertilizers. The greatest effect is achieved when the number of these vehicles provides a full load of the loader at different distances from storage to the field. The offered mathematical model allows to establish initial information to calculation of structures of the mechanized detachments and conditions of their work, to define the optimum sizes of the mechanized detachments for various types of cargo, transport, distributive means. The use of an additional constant number of car-dump truck reduces energy costs, reduces the range of direct-flow technology, increases the possible amount of solid organic fertilizers.
