This paper describes the author’s views on durability and service life of concrete bridges in North America, considering the past, present and future. Historical materials and practices have resulted in disappointing durability and service life that does not meet modern expectations. In recent years formal service life analysis and prediction has been implemented as part of the design process for major projects, typically involving numerical modelling of time to corrosion, and mitigation or avoidance of other forms of deterioration by empirical methodology. These efforts are, however, hampered by a lack of an accepted service life design standard which is adapted to North American practice and materials. Work is under way to answer this need. In the future, further development is needed to provide a better match between expectations and reality, a more practical definition of “service life”, validation of design features implemented to mitigate or avoid deterioration for which there are no available time-based models, and improved validation of numerical modelling parameters that describe exposure conditions and material resistances.

The definition of effective improvement vectors is currently one of the most pressing challenges facing the industry representatives. The transition to the sixth technological mode effectively contributes to competition intensification in all markets of industrial products. This is largely due to the fact that existing process systems are at the peak of their effectiveness. Further development requires qualitative changes. However, the principal improvement is a long-term and high-risk process. For this reason the issue of creating effective models for assessment of the strategic lines of processes improvement becomes increasingly important for industrial enterprises. This article considers in details the vector of industrial enterprise processes improvement based on the integration of new materials. As a result, a model allowing to assess a perspectives level for integration of new materials in industrial enterprise processes is created.

The problems of ensuring effective management and forming competitiveness of industrial enter-prises are relevant regardless of the conditions for conducting business activities. The fact is that the competitiveness of business structures in modern conditions is not ensured by simply owning factors of production (labor, capital, land), and even entrepreneurial talent is not currently a source of obtaining stable or exclusive competitive advantages. In order to obtain sustainable or exclusive competitive advantages that constitute strategic competitiveness, the business structure needs to have an intellectual (educational) component of development, including the production and implementation of innovations, as well as readiness for changes. Subject of research. On the basis of innovative foresight, ensuring the competitiveness of business structures of the production industry is a set of organizational, managerial and economic relations that arise in the process of formation. Purpose and objectives of the study. Development of proposals to improve the competitiveness of business structures based on innovative foresight. A number of theoretical, methodological and practical issues related to the formation and implementation of a strategy for managing the innovative development of entrepreneurial structures based on innovative foresight remain insufficiently studied and require further development of rules for its creation and functioning. At the same time, despite a detailed description of the problems of strategic management of innovative deve-lopment of business structures, the research of foreign scientists was carried out in relation to the relatively stable conditions of the economy of developed countries, the practical application of the mechanisms proposed by them in the conditions of the Kazakh economy requires mandatory revision, taking into account the specifics of the modern economy and industry.

AbstractFor the further development and more efficient operation of the sharing economy, a fast and inexpensive peer-to-peer payment system is an essential element. The aim of this study is to outline a prototype that ensures the automation and decentralization of processes through smart contracts without blockchain technology. The model has been built based on the narrative that a community currency created through smart contracts can promote genuine practices of sharing as opposed to the profit-oriented approach that most of the currently operating sharing economy platforms have. Features of the model, such as ease of use, high-speed transactions without transaction cost are benefits that can provide a more efficient alternative to the traditional or to the cryptocurrency-based centralized sharing economy platforms.

The article is devoted to the definition of the content and the system of expert activity in the field of computer technologies, which is based on the results of determining the general system of expert activity. Expert activity should be understood as the implementation by authorized agents on the basis of special knowledge in the field of science, technology, art, crafts, etc. Studies of objects, phenomena and processes in order to provide scientifically substantiated conclusions on the diverse issues that arise in the process of life of society. Such a definition of expert activity includes both judicial and non-judicial expert examination. At present, more than 500 laws are adopted in Ukraine, which in one way or another concern the conduct of expert assessments (most of them are valid at 2019). But no any among that laws directly devoted to the expert work in the field of computer technology. So the system and content of the expert work in the field of computer technology should be established, based on knowledge of the object of expertise – computer technology. It is considered as synonymous with the concept of “information technology” or “information and communication technologies”. Information technology – it is a purposeful organized set of information processes using computer facilities, which provide high speed data processing, rapid information search, dispersal of data, access to information sources regardless of places of their location. The system of expert activity in the field of computer technologies includes examinations belonging to a group of judicial (engineering, commodity, forensic, etc.) and non-judicial (scientific and scientific and technical expertise; examination of issues of quality and conformity of goods (products) to certain requirements; examination of issues of information security; examination of issues of environmental impact and the environment of human life, etc.), as well as presented by different kindsand species examinations that have different goals focused on the study of computer technology in their various aspects and provides solutions to diverse issues.

Abstract. Taking into account global development trends, integration and globalization processes, encourage the search for and further development of new products, services and management mechanisms. The economic-mathematical model of optimization of parameters of type NBIC-direction of competitive advantages is developed. The model is formed by the criterion of maximizing  the net discounted cashflow. Based on the developed scientific and methodological approach, 4 types of NBIC-direction of competitive advantages of telecommunication enterprises are proposed, which are based on a combination of levels of innovative activity of the enterprise (from low to high) and complementarity of cashflow management (from low to high). As a result, the types of NBIC-direction of competitive advantages of the enterprise are proposed: adaptive-passive, adaptive-active, object-oriented; foresight-progressive. Complementary cashflow management involves a balanced distribution of cashflows by certain NBIC-components, namely: Nano-components (application of Nano-development stop rovide high-speed telecommunications), Bio-components (introduction of artificial intelligence in organizational culture, implementation of self-organization in the enterprise), Info-components (introduction of innovative standards of telecommunication activity, information software in business process management), Cogno-components (cognitive flexibility of top and middle managers, ability of personnel to complementarity, development of knowledge management system at enterprise, introduction of system of continuous training of all employees links). Thus, the combined use of these components provides an increase in cashflows and forms a modern platform for breakthrough competitive development of enterprises. Keywords: management, competitive advantage, cashflow, innovation, complementarity. JEL Classification B26,  D61 Formulas: 14; fig.: 3; tabl.: 2; bibl.: 15.

The problem of definition of propulsion loss related to ship steering is addressed. Performance criteria representative of propulsion losses due to steering over a range of operating conditions including operation in calm water and a seaway are considered. Criteria are derived from strict analytical considerations and from empirical assumptions based on experimentally derived hydrodynamic data. The applicability of these various criteria and the implications for both assessment of relative performance of existing ship autopilots and for the design of new steering controllers is discussed in relation to simulation results for a high-speed containership.
