    Mechanization in agriculture & Conserving of the resources, Vol. 68 (2024), Issue 2, pg(s) 49-51

    In order to address multiple UN Sustainable Development Goals, we aim to revolutionize iceberg lettuce harvesting with intelligent robots. Our team, comprised of agricultural producers and engineers, has utilized TRIZ methodology, brainstorming, and other techniques to develop an agricultural technology solution: an Integrated Complex that automates harvesting and loading of produce onto transportation vehicles. Our design leverages state-of-the-art deep computer vision – a form of AI that analyzes camera images – to precisely locate mature lettuce heads. The robot identifies optimal grasping points for harvesting and carefully places the heads in a designated transport area. With deep learning at its core, our robots will optimize yield, reduce waste and costs, ushering in a new era of intelligent agriculture.

  • DOMINANT TECHNOLOGIES IN “INDUSTRY 4.0”

    Calculation of telescopic-boom bending stress capacity using fem software, in support of project logistics decisions

    Industry 4.0, Vol. 8 (2023), Issue 8, pg(s) 401-405

    Complex structural steel structure projects must be realized with the aid of specialized logistical technologies to meet all the design technical specifications. Selecting which equipment to employ, particularly when we need to elevate heavy structural steel components at an elevation higher than 8 meters, requires not only experience and the use of standard techniques for the logistic management of construction processes but also requires stress capacity calculations of the constituent elements of the machines that we will use for the implementation of the project. An indispensable machine for the realization of steel structures is the telescopic forklift, which serves to lift steel elements at different heights and positions, for a relatively long time, to assemble structure elements such as columns, trusses, beams, automated cranes, etc. In this paper, we have designed a telescopic forklift and calculated the stress capacity of the structural elements that compound the telescopic-boom, using the finite element software (FEM) Solid Works. Carrying out simulations with the corresponding load that we have to deal with in the realization of the project, allows us to change the section thickness of the telescopic boom or to use other logistic equipment with a higher capacity.

  • Fundamental nature of logistic processes and opportunities to digitalization

    Innovations, Vol. 7 (2019), Issue 1, 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.

  • THEORETICAL PROBLEMS IN INNOVATIONS

    INNOVATIVE APPROACH TO THE DEVELOPMENT OF AUTOMATED LOGISTICS INFORMATION SYSTEMS

    Innovations, Vol. 6 (2018), Issue 3, pg(s) 89-91

    Technological advancement driven by innovation, fundamentally new industrial technologies and artificial intelligence, will naturally exert greater pressure not only on the growth of production but also on its structural properties which are expected to undergo significant changes. Moreover, the improvement of technological, auxiliary and information activities will invariably be regarded as a crucial factor in the development of modern production. Thus, with the structural transformation having been effected, the new communication and information achievements are more likely to reinforce the relationship of production with its external logistics components. In addition, it should be borne in mind that the production of the future will be constructed as a complete whole comprising the respective technical, technological and information processes along with the functionally integrated production components, including those of the logistics system. The purpose of the present paper is to explore the possibilities for designing automated logistics information systems and to propose an innovative approach incorporating not only the specific in-house (intra-company) logistics but also considering its interdependent relationship with the other logistics processes that have been excluded from the company’s core business activities.

    THE INFLUENCE OF DISTANCE CALCULATION ON THE LOCATION OF CENTRAL WEREHOUSE

    Trans Motauto World, Vol. 3 (2018), Issue 1, pg(s) 21-24

    Choosing the right warehouse location is very important question which should be considered with great care, because it has a direct influence on the operating cost. For solving this problem many methods are on disposal. According to the way of determination of new warehouse location these methods can be divided in two groups’: qualitative methods and quantitative methods. Quantitative methods are often used in practice from the reason greater objectivity and possibility to analyse obtained results. Most often used methods are: gravity method, load distance method, Weber problem and many others. For calculating of distance in the load distance method two approaches are in use rectilinear distance and Euclidean distance. Neither one of these two approaches credibly describes transport routes because they not taken into consideration any physical obstacles that might occur between potential warehouse locations. With the goal to determine the influence of distance calculation on the result of the load distance method, choice analysis of optimal location of warehouse for retail stores, shops in the urban area was performed and presented.

  • LOGISTICS LEGAL REGULATION PROBLEMS

    Machines. Technologies. Materials., Vol. 8 (2014), Issue 8, pg(s) 5-7

    Relationships that are the subject of logistics in general, in principle have still not been resolved from a juridical standpoint. Even individual types of logistics do not have holistic, integrated legal regulation. However, even the legal regulation of the transport logistics is a fragmented set of norms regulating individual types of transportation, but not a transport logistics in general.

    It is hard to imagine that in principle it is possible to develop a set of international legal standards, which would constitute a coherent legal system ensuring the functioning of macro-logistics systems, i.e. the so-called “the international logistics right" or "the right of international logistics systems”. International practice is on the way of the development of legal regulation of individual logistics operations, but not of the logistics in general.

    Many of the logistics spheres are not regulated by international law even on that level. Moreover, a large number of logistics operations is not regulated, even at the level of national law. Management of the goods distribution process, from the legal point of view, is one of the most “non-image” fields of economic activities.

    There are adopted many international agreements in the field of international goods distribution (especially in the field of transport and customs regulation). However, majority of these agreements have hardly representative character (many of them, which are adopted quite a long time ago, still await either entry into force, because they do not have the required number of ratifications).
    International trade interests, the process of international division of labor, and the internationalization of economic life have created a special tool of legal regulation – "Lex mercatoria" (international commercial law).
