The paper presents the process of automated designing and parametric modeling of fixtures for manufacturing grapple buckets using the CAD system. The presented grapple buckets are designed for bulk materials and they are part of the grapple construction. Grapples are installed on cranes, excavators and other specialized machines. A methodology has been developed that covers all stages of design – from the creation of 3D models of the parts, sub-assemblies and assemblies, to the generation of design documentation through template files. The presented approach allows the development of parametric models with multiple configurations, which cover different variants of the products. Using the presented methodology leads to a reduction in the volume of generated documentation and optimizes the design process. Data management within a PDM system ensures centralized storage, actuality and accessibility of information.

The development of energy in our country is one of the good examples, thanks to which it can be claimed that Bulgaria is growing into an industrial country. The study of the stages in this development shows a different attitude towards this industry during the first half of the previous century and then, until the end of the socialist period. Until the middle of the century, energy was extremely underestimated as an area on which the general industrial growth depended, it was neglected financially as a secondary area, for which the differences remained from investments in other directions. A quite natural consequence of this was the weak technical training of the intelligentsia and the inability to develop its own energy production, which led to technological dependence on more developed countries. After the middle of the century, a reversal is noticeable, thanks to which the negative trends are abandoned. There are results that speak for the prioritization of
energy policy.
In addition to being singled out as a separate industry, the energy industry also robs the largest capital funds. The leading understanding is that without the development of energy, there would be no development at all. Undoubtedly, Bulgaria’s great achievements in engineering, metallurgy, transport and other industrial sectors would not have been possible without the successful development of the Bulgarian energy industry.

Explosive changes in technology are having a significant impact on all industries. Robotics, artificial intelligence, cyber physics systems, cloud computing, IoT and blockchain technology, 5G, nanotechnology, 3D printing are all defining elements of Industry 4.0. The integrated use of these methods enables the perception and display of the external environment, which significantly enables improvements in each industry. In the future, we expect a fusion of physical, digital, and biological technologies, which will provide new opportunities for innovative solutions. The authors of the present study present a future study to predict innovative solutions to key global challenges.

The main condition for the effective use of existing reclamation systems in Ukraine is to increase the productivity of reclaimed lands along with improving their ecological condition. This is emphasized in a number of state documents, namely: Presidentia l Decrees, Resolutions of the Verkhovna Rada, Laws of Ukraine. One of the main reasons for the weak dynamics of the revival of the domes tic reclamation complex is the lack of qualified management and technological staff in the infrastructure that provides reclamation agriculture. Therefore, in the educational process these issues are given more and more attention. Reclamation agriculture is considered b y scientists as a complex technology for sustainable development of production in the agricultural sector of the economy. There is a systematic approach to the development of modern technologies and technical means of irrigation for the sustainable development of agricultural production, obtaining quality products, preserving the fertility of lands, fauna and flora that inhabit it with important conceptual tasks of the educational process and research and production activities. Current strategic issues include: the formation of water policy in Ukraine in view of the availability of water resources and the development of adaptation measures in the context of climate change; development of conceptual bases of restoration and development of irrigation and drainage in Ukraine. And also – water resources of Ukraine and modern methods of research of aquatic ecosystems; scientific bases of formation of sustainable bioenergy agroecosystems; system of laboratory diagnostics of water-physical properties of soils; scientific and methodological bases of organization and conduct of ecological and reclamation monitoring; water and ecological risks of transformation of reclaimed lands and ways of their minimization; information technologies in scientific research in the field of agricultural reclamation, etc. Important issues in the development of modern technologies and technical means of irrigation also include: conceptual principles of irrigation management; features of designing irrigation systems; method of setting watering dates – the basis of irrigation regimes; use of the method “Penman-Monteith” for irrigation management; irrigation management based on phytomonitoring; use of remote sensing data for irrigation control; Irrigation management information system “Irrigation online”; operation of irrigation systems; technologies of repair and restoration works on hydraulic structures of irrigation systems, etc.

It is established that the main activities include: exercising control over the rational use of resources; reducing the cost of using and maintaining outdated equipment; increasing of production capacity; upgrading of equipment; improvement of production technology; production of unique products and improvement of their quality; diversification; automation of the production process by eliminating manual labor; reduction of pollutant emissions, search for new sources of raw materials; rational use of working capital and fixed assets. It is noted that marketing directions in the process of monitoring and adjusting the strategy, diagnostics and finding prospects for its further use include a set of actions concerning: exploring new markets for products; use of discount system for goods and services; application of modern pricing methods; product updates; production of new products according to existing orders; new methods of product promotion; improving customer service. The financial directions in the process of monitoring and adjusting the strategy, diagnostics and finding prospects for its further use are determined, they are aimed at providing the process of development and implementation of the IA strategy with sufficient financial resources, correlation of the planned effect with the achieved, estimation of the amount of expenses for carrying out research works, development technologies, their introduction into production, production of new products, its supply, search for consumers. The justified use of financial directions in the process of monitoring and adjusting the strategy, diagnostics and finding prospects for its further use allows to create some methods of protection from risks impact, to improve financial activity of the enterprise, to rise the effectiveness of IA organization, to increase sales volumes.. The factors of influence on the development of innovation strategy and the development of innovation activity of industrial enterprises are suggested.

The importance of agriculture lies in the fact that its organic substances are an irrevocable source of energy without which the existence and everyday life of man and a substantial part of the animal world are impossible. Man, as a higher biosystem, defines the nature and importance of agriculture as a production sector.
