The extension of the external competitive environment requires searching of new reserves to reducecosts while providing high quality services. The issue of regulating intra-industry relationship on the basis ofoptimizing the costs of operation, maintenance and repair of rolling stock be at this time quite relevant.

The use of digital and satellite information systems for the increase of quality and prompt maintenance and repair of rolling stock allows solving important transport tasks. On the modern stage the transportation process sets high requirements to operation of rolling stock that should be regulated by state standards. Modern machinery and technology should promote implementation of high-quality production in order to extend the life cycle of any product that responds the realization of production process. The international practice of standard application convincingly proves it. The paper proposes an organization of complex systems aimed at provision of operational reliability of rolling stock. The authors have determined possible reasons of non-compliance of the standards. As a result, they have set tasks on carrying out modern monitoring and execution of maintenance and repair.

The paper analyzes the technological preparation of production at the railcar enterprises in terms of developing technological processes and processing sets of technological documents. Factors affecting the quality of technological preparation of production for maintenance and repair of rolling stock are considered. In contrast to the previously performed works, where the assessment of the level of technological training was carried out by experts of a scientific organization, the initial data in the article were the results of a survey of specialists of technical departments of structural divisions of the car industry of the Sverdlovsk and South Ural Railways. Based on the method of expert qualimetry, the weight of factors that have the greatest impact on the quality of technological processes is estimated. As a result of the survey, a low level of automation of design processes was established, which consists mainly in the design of technological documentation. It is shown that the degree of depth of development and detail of technological processes is at the level of the route description

This chapter provides a basic understanding of emerging key information and communication technologies which are increasingly critical for economic growth and development. It establishes the distance to high-quality access to the internet for the least developed and other countries. Broad-based access is key in order to make use of ICT-related innovations. The chapter underlines the importance of governments creating a more open and competitive environment in order to attract infrastructure investment in terms, among others, of fibre-optic rings and cable links, foster rivalry among suppliers of services, thereby benefiting users and consumers with lower prices and better-quality services. Ultimately, the challenge is, through sound public policy, to steer societies from being marginalized by the major technological changes in information and communication.

The value of the life cycle of rolling stock wheels is determined by the frequency of maintenance, in the process of which the turning is carried out to restore the profiles of the rolling surfaces, or the replacement of completely worn wheels. Traffic safety depends on the technical condition of the wheels of locomotives and wagons. Maintenance and repair of wheelsets accounts for about 30% of all costs of Ukrzaliznytsia's rolling stock repair units. Wheel repair technologies are based on the complete restoration of wheel profiles by turning, using which, their life cycle is reduced, and costs increase by 20% or more. The railways of Ukraine use an outdated, unreasonable, inefficient system of control over the formation of rolling surfaces in operation. Therefore, there is a need to create a scientifically sound approach to methods of extending the life cycle of the wheels of locomotives and wagons while ensuring the safety of railway rolling stock. According to the proposed scientific approach, the wheel profile is restored to optimal parameters, which provides an extended life cycle of wheelsets. As a result of the developed scientific approach the life cycle of wheel pairs will increase by 15… 25% and the expenses of the railway for their repair will considerably decrease.

The efficiency of commercial automobiles and wheeled military vehicles mainly depends on the choice of maintenance (M) and current repair (CR) concept. In the paper the difficulties of adapting the (M) and (CR) planning strategies to the structural characteristics of modern transport facilities are pointed out. The advantages of using the (M) and (CR) random strategy for transport facilities based on the stochastic nature of failures and malfunctions are substantiated. Considering the failures and malfunctions as random values and identifying the patterns of their distribution based on γ percentage resources, it is proposed to develop a list of regulated maintenance and repair work, periodicity and labor intensity based on a random strategy, which will increase the efficiency of preserving the technical resource of the rolling stock throughout the entire life cycle of the vehicle.

Innovation is one of the basic assets needed for organizations to survive<em> </em>in a competitive environment. Organizations such as higher education also need strong innovation in order to continue to compete and produce high-quality graduates. This study aims to analyze the factors that influence the innovative behavior of lecturers, especially based on organizational learning and organizational commitment. The research was conducted at STIK-PTIK with a sample of 108 lecturers who were taken randomly. Data collection using a questionnaire with Likert scale 1-5 and data analysis using path analysis. The results showed that organizational learning and organizational commitment had a positive direct influence on the innovative behavior of lecturers. Organizational learning is also known to have a positive direct influence on the organizational commitment of lecturers. Other findings indicate that organizational commitment plays a role in the influence of organizational learning on innovative behavior. Based on these results, then factors organizational learning and organizational commitment need to be improved in order to increase the innovative behavior of lecturers.
