MODEL OF COORDINATION OF TRANSPORT FLOWS OF GRAIN TRANSPORTATION BY VEHICLES FROM FIELD TO TEMPORARY STORAGE POINT

Abstract

Introduction. Most of the works have received that the problems of improving the efficiency of use in transport systems of vehicles, preserving grain and bringing it into the product are resolved during the campaign of harvesting grain crops. The purpose is to formulate methodological prerequisites for substantiating the model of coordination of transport flows of transportation of grain by motor vehicles from the field to a temporary storage point. Results. It was obtained that on basis of production opportunities, the cost of harvesting and transportation of grain, the capacity of storage points there is a possibility of solving the problem of determining the optimal plans of harvesting and distribution grain. It is proposed that the volume of transportation of agricultural grain from the field by the campaign to the storage point and the intensity of the variant of the campaign of the field of field harvesting field is characterized only when the production and transportation plan, if there are clear conditions. At the same time, the volume of agricultural grain transportation from the field by the campaign to the storage point describes the component of the production plan, and the intensity of using the variant of the campaign of the field of harvesting agricultural grain – a transport plan. The additions of the target function will be presented in the form of equations, which reflect accordingly production and transport costs for the implementation of the plan. The production and transmission plan is considered acceptable if it satisfies clear conditions and optimal, if, in addition, delivers a minimum of function. The solution of the proposed expressions is to solve the problem of partial integer linear programming and is characterized by a number of specific features. The algorithm involves the construction of such production plans, which is minimal. Since the production plan obtained in the first step is the best from the standpoint of production costs, only a worse production plan can be improved, but getting a lot of savings on transport costs can be achieved. Conclusions. In this article, we show that there are methodological preconditions for justifying the model of coordination of transport flows of transportation of grain by motor vehicles from the field to a temporary storage point. It is established that the model for determining the volume of transportation of threshed grain from combines to a temporary storage point, taking into account the loss of grain when harvesting after optimal agro -termini, considers the operations of harvesting and transportation of grain as a single indivisible process, and allows, thanks to the rational distribution of transport flows of harvesting.
