In the military units of the National Guard of Ukraine, a planned preventive maintenance system has been introduced, which provides for mandatory implementation with the due frequency of the established set of works in the process of using and storing machines. Maintenance for everyday machines includes inspection, daily maintenance, maintenance no. 1, maintenance No. 2, seasonal maintenance. Technical services No. 1 and No. 2 are aimed at ensuring the uptime of machines, reducing the intensity of wear of parts, detecting and preventing malfunctions. It is carried out with a certain frequency. License plates are planned for a year in the "Annual plan of operation and repair of automotive equipment of the military unit" and for a month in the "Plan-schedule of maintenance and repair of machines". Such an organization of maintenance is suitable for domestic brands of cars, but not for cars of foreign production. This is due to the fact that factories manufacturers of foreign-made cars offer other types of service and other frequency. It is proposed to solve this problem by adapting the types and frequency of foreign-made machines to the existing MOT system in NSU, or by organizing a planned preventive system for individual maintenance of NSU cars. The essence of which is to accurately conduct the types of maintenance recommended by manufacturers for each car within a certain time frame. To do this, it is proposed in each military unit to develop annual and monthly plans for individual maintenance of military vehicles according to the above forms.
Assessment of the quality of traffic management and design solutions in the field of traffic management in cities, complex systems for organizing the movement of cities with a population of more than 100 thousand people residents, temporary schemes of organization for the period of overlapping of significant sections of the street network is combined with the need to take into account a large amount of data to resolve contradictions of uncertainty of an objective and subjective nature. Taking into account the variety of factos to assess the effectiveness of the organization and management of traffic is possible only for small sections of the street network using advanced information technologies to improve the quality of automated traffic management through the implementation of optimization principles. The effectiveness of traffic management can be assessed by many factors that depend on its management. As an objective function of traffic management, a number of authors suggest using the following values: the number of road accidents, socio-economic damages from road accidents, the amount of harmful substances, the total travel time along the route, the number of stops per trip, the skip rate, the average delay of the crew per cycle, the average downtime, connection speed, traffic intensity, etc. The proposed calculations of the amount of the total risk and the average length of a person's life, which use basic normative data, allow to give a quantitative assessment of the danger of atmospheric air pollution. In this regard, environmental risk can be applied as an objective function of traffic management. As can be seen from the above results, both the environmental risk, and the time the car travels from one point to another, and fuel consumption are determined depending on the delays of vehicles in front of regulated intersections. Therefore, it is advisable to recommend as a target function for optimizing traffic management the value of the total time of vehicle delays in front of intersections of the urban street network in one cycle of regulation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
