| Annotation: | Methods. The results are obtained with the following methods: the method of abstractions in determining the essence of the category of «social justice»; general to specific method in establishing the unity of the existing concepts of social justice; standard methods of sociological research in determining the value system of the Ukrainians towards social justice. Results. As a result of the conducted research, the possible value of financial losses during the sale of such goods as sand, wheat, fodder corn, food corn, iron ore pellets, titanium ore, and rolled ferrous metals was determined. These losses can range from hundreds to tens of thousands of hryvnias. The list of available offers of electronic scales for weighing goods on land was analyzed, the value of error when weighing with automobile and wagon scales was determined. The possibility of describing the error using a logarithmic equation has been demonstrated, which proves that the relative weighing error decreases as the mass increases. The equation formula was found by the analytical economic-mathematical method using Microsoft Excel spreadsheets. Based on the use of the properties of the dispersion of weighing, a logistical and organizational method of increasing the accuracy of weighing has been developed, which consists in several repeated weighings and determining the resulting weight as the arithmetic mean of all attempts. A formula was developed to determine the optimal number of repeated weighings to increase accuracy, taking into account the cost of one weighing and losses during a single weighing. The method of weighing cargo on water was analyzed, its limitations were revealed and the need for its improvement was indicated in terms of taking into account such factors as water salinity, through which the draft of the vessel is measured. An analytical dependence has been developed to determine the weight of the goods loaded onto the vessel by its draft depending on the salinity of the water in which the vehicle is located. Novelty. In the process of analyzing exporters’ losses during product weighing, logistical and organizational measures have been developed that are guaranteed to reduce losses. Practical value. Techniques are proposed that will reduce the exporter’s losses when weighing goods both on land and at sea, which will allow adjusting the size of the weighing error with available devices. |
