PARAMETERS AND INDICATORS OF MILK TRUCK FUNCTIONING AT DAIRY PROCESSING ENTERPRISES

The analysis of existing methods of determining automobile fleet parameters at the area is carried out and their disadvantages are substantiated. The proposed method of substantiation of the parameters of the milk trucks of the dairy enterprise involves the implementation of five complementary stages. The first stage provides the creation of a database of production conditions and characteristics of vehicles. The second stage involves the definition of rational customary routes for the delivery of milk from the points of harvesting to the milk processing enterprise for variants of the fleet of cars with the same cargo. In the third stage, the calculation of the functioning indicators is carried out, the needs for identical cargo vehicles and their basic parameters are determined. The fourth stage provides the definition of rational local routes for variants of the fleet of cars with different cargo. The fifth stage involves the indicator calculation of the milk trucks functioning and the definition of effective parameters for dairy processing enterprises, which provide the minimum cost of resources for their operation. It is established that with the increase of cargo tank truck capacity from 1.3 to 11.5 tons, their average daily run in the intensive milk harvesting period is reduced from 2.64 to 0.57 thousand km, which is described by a second degree polynomial. At the same time, the need for tank trucks for these conditions is reduced from 12 to 5 units. An efficient variant of the transport infrastructure of the dairy processing plant involves the attraction of 6 cars with a cargo capacity of 3.7 tons and trailers with a cargo capacity of 0.9 tons. The proposed method and the results of the conducted researches underlie the creation of an information support system for decision making in logistics systems of milk procurement. They also underlie the planning of the transportation infrastructure of the dairy enterprise.
