Abstract
<p class="a"><span lang="EN-US">We have studied the influence of changing production conditions and components of transportation processes on the need in specialized vehicles in the milk harvesting systems. Based on the prediction of the daily volumes of milk harvesting from family dairy farms, it was found that there are two periods of milk delivery over a calendar year </span><span lang="EN-US">‒</span><span lang="EN-US"> the intensive (from May to September) and nonintensive (remaining months of the year). Based on timing the transportation processes using the road tanks Hyundai HD65 STD+G6OTA3.9, we performed production experiments. It was established that the durations of transportation operations are described by the Weibull distribution law. Specific durations of loading the road tanks Hyundai HD65 STD+G6OTA3.9 at family dairy farms and their unloading at a processing plant have a mathematical expectation of 0.92 and 0.52 h/t of milk, respectively, and their mean deviation </span><span lang="EN-US">‒</span><span lang="EN-US"> 0.018 and 0.008 h/t of milk.</span></p><p class="a"><span lang="EN-US">Using production conditions at Brodovskyi Region in Lvov Oblast, Ukraine, as an example, we conducted the simulation of transportation processes of milk delivery from producers to a processing plant taking into consideration the changing production conditions and the components transportation processes. It was established that an increase in the daily volumes of milk harvesting from 6 to 66 tons/day leads to an increase in the estimates of mathematical expectation of the total daily quantity of routes traveled by the road tanks Hyundai HD65 STD+G6OTA3.9, in line with a linear dependence. The mileage of these road tanks and the duration of their utilization grow at an increase in the daily volumes of milk harvesting according to the polynomial dependences of second power. The cargo turnover varies partially discretely from 820 to 4,610 t·km, due to a change in the technological need in road tanks.</span></p><p class="a"><span lang="EN-US">It was established that a need in the specialized vehicles Hyundai HD65 STD+G6OTA3.9 over a calendar year changes from 1 to 4 units. In this case, execution of transportation processes from January to March and from October to December within a separate calendar year should be organized in one shift, and from April to September, in two shifts. The derived distributions of the changing components of production conditions and transportation processes, as well as the dependences of road tanks utilization on the volumes of milk harvesting, underlie the creation of an information decision support system in the milk harvesting systems. In addition, they form the basis for planning the work of a fleet of specialized vehicles and for designing the systems of milk harvesting.</span></p>
