Justification of the warning replacement of the elements of technical means of customs control

The effectiveness of customs control of goods transported across the customs border to a significant extent depends on the reliability of the technical means of customs control. The reliability of their functioning is ensured by the timeliness of preventive replacements of the elements of these means. The random nature of the failures of these elements and their relatively high cost make it necessary to thoroughly justify the terms of preventive replacements. The justification of the terms of replacements presupposes the existence of an appropriate scientific methodological apparatus. The development of this apparatus is the goal of this article. The scientific and methodological provisions developed in the article will make it possible to reasonably determine the replacement times and the composition of the replaced elements of the technical means of customs control. Their use will reduce the cost of maintaining the technical means of customs control in working condition. At the stage of creating the technical means of customs control, it will improve the quality of the operational documentation, and in the course of their operation, based on the collection and processing of relevant statistical data, will allow for a reasonable correction of the replacement time.
