Objective A multi-criteria approach was developed to assess the effectiveness of the implementation of on-board information and control systems that reflect the impact of the implemented equipment in the control system of a highly automated vehicle, taking into account the establishment of their indicators. Methods A multi-criteria approach is used to determine the rational composition of the on-board information and control system, taking into account the weight coefficients and limitations of transport systems. Results Based on the model of integration of the intelligent on-board information and control system of the vehicle into the transport infrastructure, the criterion of controllability is determined - the coefficient of efficiency of vehicle management. Conclusion The results of research shows that the controllability of the vehicle increases by 14.3% when the automatic function of connecting manual control is introduced into the on-board information and control system, on the basis of which the dependences of calculating the critical distance and time when driving an unmanned vehicle are clarified.

Introduction This studypresents a comprehensive evaluation of the effectiveness of passenger transportation using intelligent technologies based on economic, technical, and operational efficiency parameters. It reviews existing approaches to efficiency assessment and proposes an optimal set of criteria for assessing the efficiency of the passenger transport process, which will allow for better planning of routes, movement schedules, and choice of transport rolling stock. Objective This study aims to provide a better assessment of the efficiency of passenger transport using intelligent technologies. Aims This article aims to carry out an integral assessment of the efficiency of passenger transport using intelligent technologies based on the criteria of economic and technical-operational efficiency, which will allow better planning of routes and schedules and selection of rolling stock Methods In order to obtain a comprehensive criterion for assessing the efficiency of the transportation process, diverse techniques, including computer and mathematical modeling, algorithm theory, mathematical statistics, observation, and measurement, were employed. Results A general criterion was created in order to evaluate the efficiency of passenger transportation processes based on the overall costs for both the user and the operator. Furthermore, a specific criterion of efficiency for passenger transportation processes has been defined: passenger-kilometers traveled. The applicability of the model is evaluated in a bus corridor in Havana. The results show that due to external factors, namely overcrowding, overall costs decrease at the same rate for both 12-meter and 15-meter buses with different intervals, while the number of passengers transported per kilometer increases at a faster rate for larger buses. Conclusion Choosing a criterion to assess the effectiveness of the passenger transportation process requires considering various aspects of importance that will result in passenger comfort and safety, as well as the effectiveness of the transport process. To solve this problem, it is necessary to do additional research and analyses to determine the most appropriate set of criteria under specific conditions. In particular, consider vehicles of smaller capacity to take into account volumes with variable demand.

Background The road transportation sector faces rising task complexity, driving the development of localized telematic traffic control systems. Integrating cutting-edge technologies is essential, surpassing administrative measures. A methodological approach is imperative for successful implementation. Objective This study aimed to improve the efficiency of the implementation of intelligent information and communication technologies in the passenger transport system of urban agglomerations on the basis of objective assessment and rational choice of hardware complex in the field of vehicle traffic management.

In the course of solving the problem of increasing the efficiency of safe life support for autonomous buildings and structures, conceptual methodological approaches were identified for automating the processes of monitoring the state of smart infrastructure technical systems, which will significantly increase their efficiency through the combined use of elements of individual control systems, optoelectronic event detection and recognition (ECO). To this end, the methodological foundations for the calculation and design of technical systems were formed on the basis of the developed methods of analysis and technical and economic modeling of objects, evaluation of the technical and economic efficiency of technical informational systems, calculation of dynamic characteristics and evaluation of indicators of the quality of energy supply of objects, as well as a comprehensive methodology for evaluating the effectiveness of multi-stage visualization systems, taking into account the priority study of issues of feasibility study and their rational construction smart infrastructure.

The necessity to generate statistical data of diagnostic parameters of vehicles during their operation is determined. An algorithm for optimizing the supply of spare parts has been developed, taking into account the information and logistics support for the process of replenishing their resource, and an adaptive-controlled approach has been formed in the form of a model of the process of "replacing" the range of spare parts in vehicles. A system-analytical approach to the delivery of spare parts is determined, taking into account the stepwise change in their cost. The developed theoretical provisions will significantly reduce the complexity and time spent in a vehicle idle time.

... Zemax/OpticStudio, TracePro, Code V, OSLO, ASAP, and other commercial software tools for generic illumination design are designed to simulate, create, and optimize optical components for many applications. While designing illumination schemes can be one of these jobs, these software programs lack dedicated techniques for the design and optimization of illumination systems and were not only designed with the purpose of illumination simulation in homes and offices in mind (Safiullin and Arias, 2024). The chosen tool can be different depending on the task at hand. ...

... An actual problem is the operational control of fuel quality at all stages of vehicle operation, distribution and consumption, since a significant number of qualitative and quantitative methods for monitoring certain properties of fuels are time-consuming and expensive and require the organization of specially equipped laboratories, which is associated with significant costs for their maintenance [2][3]. When operating vehicles, such methods are not applicable, due to their high cost and nonuniversality, therefore, in order to increase the reliability of power plants and provide them with high- 2 quality fuel, it is necessary to develop universal methods of fuel quality control both in the field and during the formation of their physico-chemical properties directly on the power plant. ...

Any task relating to decision-making optimization is characterized by three basic concepts-a set of candidate decisions; a set of environmental state types; and the efficiency of a proposed decision under each environment state. Here and elsewhere, we shall use the following designations: It has been found in studies [21,[41][42][43][44] that there is a relationship between the Pareto set in multicriterion tasks and the zoning method for solving "games with nature"-related problems under uncertainty [45][46][47][48].
