“…At that time, in foreign practice, much attention was paid to improving the systems of assistance in making managerial decisions, the basis of which was the automation of operations and procedures for assigning control actions [10]. The beginning of this process was laid by the formation of computer management information systems (MIS), which guaranteed the development of the requested reports, generated according to the preferences of the decision maker.…”

In the context of the coming digital globalization of the economy, an important factor in increasing the level of development of ameliorated agriculture is the widespread introduction of innovative agricultural technologies and agricultural production management into the practice of the domestic agro-industrial complex. The methodological basis of research is based on information and analytical methods, methods of expert assessments, system analysis and synthesis. Based on the results of the studies and the performed assessment, the role of innovation systems in the structure of the agricultural production economy and the experience of their application in the ameliorative sector of the economy in comparison with developed foreign countries are characterized. The influence of innovations on the efficiency and productivity of labor is shown and proposals are presented to reduce and eliminate the technological backwardness of agricultural production on reclaimed lands, consistent with the trends in the development of technologies for the production of advanced industries of the domestic and world economy. The main stages of the formation of production management systems, which provide support for the assignment of control actions, are presented. Reasons are revealed that hinder the full use of innovative technologies in agricultural production, associated with the lack of free funds among small-scale agricultural producers and their proper understanding of the strategic importance of innovations in the production process. A prognostic analysis of the innovative development of agricultural production based on “intelligent agricultural technologies”, is presented which unites objects via the Internet for receiving and exchanging information from built-in services.

“…After careful evaluation of automated processes in place at reclamation enterprises, there can be no doubt that, given a growing focus for the effectiveness of management decisions, it is necessary to improve the integration of digital systems and technologies [9]. Automation largely includes only scattered fragments of production activities, focusing mainly on accounting applications and some routine automation.…”

Today, a brand new strategy that can foster agricultural production is being shaped based on IT solutions. The paper characterizes the state and prospects for the development of digital farm management, the challenges of mastering digital innovations by agricultural enterprises and ways to tackle them at the present stage. A study is relevant due to the lack of a conceptual approach to the evolution of information digital systems in the sector of ameliorative economy in the context of growing requirements for environmental safety and competitiveness of agricultural production. The solutions to create a common information environment uniting an enterprise with suppliers of resources and consumers of products (services) are also increasingly relevant today. A methodological toolkit rests on some general scientific approaches, including analysis and synthesis, methods of deduction and systems analysis, cluster approach. After careful evaluation of automated processes at reclamation enterprises, there can be no doubt that it is necessary to improve the efficiency of information and technological support for management decisions by digital systems. The challenges are related to: lack of proper concept and methodology of modern digital systems, as well as procedures for the integration cooperation of information resources and a digital management system operations for managing them; unified algorithms for handling information; automation operations that meet the present management requirements; qualified experts encouraged to improve the use of digital technologies. The basic procedures for enhancing digital systems at enterprises include: analytical evaluation of current production situation, development of a functional design and model of the integrated digital system; creation of a mechanism for its implementation. In the process of transforming digital support for managerial actions, the following actions are possible: modification of the structure of existing processes; automation of conventional technological and organizational production procedures; alignment of existing processes subject to the technologies being integrated; identification of new opportunities for operations.

“…The results of the calculation of the culvert with this design scheme show that at backfilling H = 10-12 m, significant deflection moments arise in the culvert of a circular shape, causing the appearance of significant stresses. Therefore, it is advisable to search for a membranous outline of the culvert profile (Abdrazakov et al, 2020).…”

The main purpose of the study is to develop models for the strength reliability of closed spillways at earth-fill dams. The object of the research is closed mine-type spillway structures. The strength reliability model of a closed spillway structure includes a material model, a shape model, a model of actual load, and a fracture model. The material model in most cases is reinforced concrete. The shape model is very important, especially for precast culverts of glory hole spillways, because giving it a certain shape can significantly reduce the value of stresses acting in weak sections. As a result of the stress reduction, there is a decrease in material requirements, primarily for metals, leading to reduced energy and economic costs. This also makes it possible to increase the reliability and durability of such structures, increase their operational safety, and adapt them to various operating conditions. The shape model for the culvert is justified. The load model determines the behavior of the structure during construction and operation. This article suggests a justification for the methodology for calculating the strength of a precast culvert of segment blocks. The methodology allows to perform strength analysis of culverts of closed spillways with a cross-section outline similar to a membrane. The state of reinforced concrete load-carrying units under various combinations of loads has been studied. The limits of stresses and displacements, the excess of which can lead to destruction in the load-carrying units, are determined.
