  • Alternative approach to determining the innovative obsolescence of industrial products

    pg(s) 3-5

    Technological development, nowadays, has entered a crucial stage that gives precedence to the innovative obsolescence over the physical one. To that effect, of utmost importance, therefore, is the accurate identification of the extent, i.e. the degree of innovative obsolescence in an effort to assess the effect of innovation upon the technical-economic performance and social outcomes of the industrial activity. Moreover, in an increasingly globalizing economy, innovations are bound to make a worldwide impact, accelerating the innovative technological obsolescence with the level of technology being utilised is globally lagging further behind the level of today’s technology. Prolonged use of obsolete technology and outdated technological processes leads to certain losses, the amount of which is contingent on the extent of the lag range. Advanced in the paper is an alternative approach to determining innovative obsolescence of technological products and the respective solutions in pursuit of a marked reduction in its adverse effects.

  • Innovation today – a complex innovation approach to social and technical innovations

    pg(s) 13-17

    Innovation is a key component of the development of the economy, the competitiveness of national economies and the high quality of long-term performance. To acquire and maintain competitiveness is strongly dependent today on innovation. For many years innovation related studies concentrated on technological innovation. Although Schumpeter has defined innovation in a broader sence, including market and organizational innovations as well, studies mainly have left out of consideration the economic, managerial and social elements of innovation. During the last 15 to 20 years social innovation has emerged as a major area of studies in innovation. How do all the actors of the economy see it? How does one help each other? We seek answers to these questions in a research on innovation and social innovation in a wider area, from which the present study focuses on social attitudes in technical and social innovation.

  • Fundamental nature of logistic processes and opportunities to digitalization

    pg(s) 21-24

    Industrial development has brought about qualitative changes in the very foundation of innovation and automation. The distinctive features of enterprises with such a type of production are becoming increasingly blurred by the growing tendency for global industrial development. They become heavily dependent on the pace of development of automation, industrial technologies, communications and ever more determined by the factors that most affect and shape the trends of that development. It is therefore of utmost importance to carefully define the distinctive features of modern logistics processes that form the foundation of the respective digital development policies, which is also the primary objective of the proposed paper. These policies are undoubtedly enforced by the very evolution of technology and are likely to define the new directions of cyber development.

  • Analysis and assessment of the financial effects of the innovative impact on the tangible and intangible assets entered into service

    pg(s) 28-30

    Upon commissioning – tangible and intangible fixed assets are recorded in the inventory inventories, which includes the cost of transport and bringing the assets to normal operation in an operating environment (including installation, test, calibration, etc.). This process is strictly regulated, both normative and factual. After the asset is released, its amortization or accrual of depreciation charges begins. During the depreciation period, wastage is recorded, but no account is taken of innovation aging. This reporting has the side effects of rapid technical developments in communications and information technology. This article attempts to provide a methodological explanation for this manifestation and to find an approach for determining the magnitude of scattering or value-estimation of the dynamic asset environment.

  • Development of a formal model for the implementation of business network reengineering

    pg(s) 31-34

    The dynamics of the environment in which businesses operate underlines the need for new tools and approaches to management engineering. There has been recently a growing interest in finding comprehensive solutions covering all aspects of the entire business management.

  • Influence of adding SiO2 nanoparticles on rheological and filtration properties of water-based muds

    pg(s) 43-46

    Drilling mud is a working fluid which consists of a water and different added additives and is used during drilling of wells. By circulating through the wellbore, it ensures continuous cuttings removal, required pressure to stop the influx of reservoir fluid in wellbore, lubrication of drilling tools and maintaining wellbore stability while drilling through various types of formations. Since the well is often drilled through water-soluble rocks, which are mostly consisted of clay minerals, the penetration of the filtrate (water) into such rocks can lead to their destabilization, so the industry is considering the application of new types of additives because conventional additives, due to their size, can not enter in pores of rocks which has very low permeability, plug them and thus reduce further penetration of the filtrate. In recent years, scientists have paid great attention to the testing of nanoparticles (most tests are carried out with SiO2 nanoparticles) for drilling through low permeability rocks. Nanoparticles are particles whose diameters range from 1 to 100 nanometers so they can enter into the pores and create a high-quality mud cake, thereby reducing the filtrate invasion and increasing the wellbore stability. This paper describes a laboratory test carried out with SiO2 nanoparticles which average particle size was 20 and 60 nm added in concentrations of 1 and 3 wt% to water-based muds. Special emphasis was put on rheological and filtration properties. By
    optimizing the concentration and size of the used nanoparticles, the rheological and filtration properties of the used drilling muds were improved.
