Solution of system of the Fredholm integral equation of the first kind

The article is devoted to the study of a system of two inhomogeneous Fredholm integral equations of the first kind with two required functions depending on one variable. Integral equations describe the restoration of a blurred image, production costs, etc. Fredholm integral equations with one desired function have been considered in many works, but relatively few works have been devoted to systems of such equations. The questions of stability for the solution of systems and the construction of a regularizing system of equations were investigated, but the solution was not constructed in an explicit form. In this paper, the kernels depend on two variables. The case is considered: in the kernels and inhomogeneities, the variables are separated in the equations; these functions are decomposed on the basis of two functions on the interval of integration. Examples of basic functions are given. A condition is determined under which the system has a unique solution in the chosen basis, formulated as a theorem. The solution is found in the form of an expansion in this basis. To illustrate the results obtained, an example is considered

To solve the formalized problem, the foundations of the methodology for assessing the need for state regulation of logistics support under non-military methods of power pressure, allowing to assess the need or redundancy of state influence on logistics support at the macro level, are proposed. This will improve the socio-economic component, for a positive effect in terms of increasing foreign trade turnover, as well as to increase employment and efficiency of human resources and lead to a reduction in the cost of production.

Review of approaches and methods to assess the comparative efficiency of technological processes and production

The article provides an overview of approaches and methods to assess the comparative efficiency of technological processes and production. It is known that the most common methods are those that assess production based on the analysis of the states of control objects, as components of production, taken into account in the automated control system, or analysis of the course of the technological process. It is shown that efficiency is the most general, defining property of any purposeful activity, which from the cognitive point of view is revealed through the category of the goal and is objectively expressed by the degree of goal achievement, taking into account the cost of resources and time. Increasing the efficiency of the enterprise is carried out using methods of analyzing the structures of enterprises, which allow, with the transparency of the structure and organization of production, to carry out accurate and high-quality monitoring of the state of the objects of the enterprise and their management. The analysis of comparative efficiency is an important component of production processes. The results of the analysis allow you to debug the work of the enterprise already at the initial stages of reducing the efficiency of its functioning. An important task is to find a mathematical basis for analyzing the efficiency of enterprises. The paper discusses parametric and nonparametric methods for assessing comparative efficiency. The main difference between parametric methods is the econometric estimation of parametric functions in the study of the interaction of costs and resources. The authors pay attention to the nonparametric DEA method, which, due to its characteristics, has a number of advantages and features. The method allows you to obtain a comprehensive performance indicator for each enterprise, and can also take into account multiple input and output variables. These features of the DEA method make it possible to successfully apply it in determining the indicator of the comparative efficiency of enterprises.

Development of information technologies in the tourism sector

The development of foreign and Russian tourist information centers is characterized. The extensive expansion of the network of Russian centers, the diversity of their activities, the accumulation of a number of unresolved problems are noted. A vector of transformations of domestic tourist information centers is proposed based on the formulation of three hypotheses: a further increase in the tourist mobility of the population; structural shifts in the tourist flow: a decrease in the share of organized tourists and an increase in the share of amateur tourists; expansion of the information capabilities of the centers. The development of the system of tourist information centers, both on the territory of the Russian Federation and in the world, is considered. This is an urgent problem from the point of view of forming a positive image of the regions in the field of international and domestic tourism. In the presence of a developed network of tourist companies engaged in the organization of regional tourism, the number of tourist information centers is small, and their development needs systematic coordination. A systematic approach to building a network of tourist information centers in Russian regions will help solve the main task of regional policy - creating conditions for more effective and harmonious development of regions and ensuring the growth of the welfare of the country's population. the article describes the conceptual foundations and economic and organizational principles of the creation and development of tourist information centers. The foreign and domestic experience in this field is summarized. Various approaches to the organization and evaluation of the effectiveness of the formed system of tourist information centers are identified. Conclusions are drawn about the need to improve the current system of tourist information centers and assess the prospects for its use in Russian practice in modern conditions.

Blockchain Based Intelligent Transport System

Blockchain technology is widely studied in these days and has vital role in the ITS and Vehicular network. Intelligent Transport System (ITS) have resolved several issues of transportation like congestion, electronic toll collection, traffic light cameras, traffic updates, and environment forecasting. The vehicular network is the ever-increasing network it is not only facilitates us but also brings new challenges with it. The mobile nature of vehicular networks it is very important to collect and broadcast information of traffic events in real-time. A little delay to broadcast important information or deciding on this information can cause a serious situation in the mobile vehicular network. Moreover, malicious vehicles in the network broadcasting false information about these traffic events cause a disturbance in the network. In large-scale scenarios, the transmission of malicious messages offers a lot of danger to the system. They can wrongly claim the roads and provide false information about the incident. These traffic events can be life-threatening and cause unwanted situations like accidents, wastage of time and other resources. Therefore, it is very much important to provide real-time information on recent traffic events and real-time authentication of vehicles that broadcast information in the network. Traditional studies are unable to solve these security issues and contain a single point of failure issue. These studies are centralized and dependent on a single higher authority. Moreover, they have serious security concerns that are harmful for vehicular network. Moreover, any vehicles are unwilling to share their private information while broadcasting information about traffic events because they are strangers to each other. And if a vehicle does not want to share its private information like name, id, etc. It is not possible to authenticate this vehicle and manage trust in the network. It means that it is very crucial to prevent vehicles to broadcast wrong information in the network while preserving their privacy at the same time. Therefore, there is a need to authenticate vehicles and manage trust in the network while preserving their privacy simultaneously. Blockchain can offer better solution to solve these issues due to its secure distributed environment and features that ensure immutability about actions. The purpose of this report is to provide real-time security and privacy in the network. It is also ensured that vehicles get real-time authenticated information about traffic incidents from legitimate vehicles while simultaneously preserving their privacy. It means that only authenticated and legitimate entities (vehicles) can participate in vehicular network and privacy of both sender and receiver is secured in the network. Details of conducted experiments are given, and shreds of evidence are provided to evaluate the performance of architectures for authentication and trust management. The shreds of evidence show that these blockchain-based systems can solve security and trust issues more effectively.
