The article covers the systematic basis for the creation of new technological processes of corn harvesting machines. Modern corn-harvesting machines have reached certain thresholds according to their technological properties that most significantly affect the final production and economic indicators of planting corn for grain efficiency, still they do not meet modern requirements. The technological properties mentioned above are hardly adjusted for wide range of physical and mechanical properties of the plants and crop parameters. This situation is caused by new machine´s working parts being viewed by researchers and developers as complex technical systems not from the standpoint of general systems theory but in terms of the use of traditional knowledge of the laws of agricultural mechanics, thus not getting proper attention to their systematic coordination with working conditions. Based on this, the paper presents a structural scheme for the system “mechanized corn for grain harvesting”, key elements of which are: agricultural (А), engineering (В) and selectional (С) supply. Interconnection of the subsystem´s elements and their consistency determine the effectiveness of the whole process. Inconsistency of the links АВ and ВC is observed. The conceptual system “mechanized corn for grain harvesting” design relates to the field with clear NO-factors: incompleteness, uncertainty, inconsistency and lack of information for decision making, thus it is important to review tasks of conceptual design from the most general constructual standpoint. The method of describing systems at the conceptual level is suggested. This systematic representation of corn-harvesting machines allows to approach the task of their workflows modeling from the most general standpoint.

A mine cannot function without monitoring systems: environmental, basic mining machinery and equipment. The exploitation of ore in the mine depends heavily on properly functioning machines and mining equipment, and acceptable for the miner technical environmental conditions occurring in underground excavations. The monitoring systems of the technical environment in underground mines are primarily telemetry and gasometry systems. The first part of the article shows the typical structure of gasometry systems operating in the Polish underground mines. The existing provisions include the so-called security systems of the mining plant. The article presents a quantitative summary of the telephone exchange types and count of main telecommunication lines operating in these systems. Monitoring systems of machines and mining equipment are an essential element of the effec-tive management of the mine, because they affect the safe operation and increase time of effi-ciency equipment. The second part of the article shows selected monitoring systems of mining machinery and equipment currently used in the dispatcher rooms of mines. Attention was paid to the monitoring systems, which are only software tools as well as those in which additionally use dedicated IT solutions for these systems, hardware and measuring tools. The table shows the types of monitoring systems and technological configurations used in underground mines, preferred for them.

The study aimed to develop a system supporting technological process planning for machining and 3D printing. Such a system should function similarly to the way human experts act in their fields of expertise and should be capable of gathering the necessary knowledge, analysing data, and drawing conclusions to solve problems. This could be done by utilising artificial intelligence (AI) methods available within such systems. The study proved the usefulness of AI methods and their significant effectiveness in supporting technological process planning. The purpose of this article is to show an intelligent system that includes knowledge, models, and procedures supporting the company’s employees as part of machining and 3D printing. Few works are combining these two types of processing. Nowadays, however, these two types of processing overlap each other into a common concept of hybrid processing. Therefore, in the opinion of the authors, such a comprehensive system is necessary. The system-embedded knowledge takes the form of neural networks, decision trees, and facts. The system is presented using the example of a real enterprise. The intelligent expert system is intended for process engineers who have not yet gathered sufficient experience in technological-process planning, or who have just begun their work in a given production enterprise and are not very familiar with its machinery and other means of production.

At present, a deep transformation of the agrobiocenose organisation under the intense anthropogenic factors’ influence is of particular importance. Thus, a significant increase in the number and harmfulness of pests’, phytopathogens’ and weeds species was noted due to the prevailing favourable conditions for their mass reproduction, expansion of habitats, and harmfulness, which inevitably leads to a significant deterioration in the phytosanitary state of cultivated crops. The phytosanitary trouble of agrobiocenoses allows us to say that today plant protection, being the final link in the cultivating technology for agricultural crops, is one of the most important stages in preserving the harvest improving the quality of the products obtained, and reducing their cost. In the current study it was tried to review the modern paradigm of the agricultural technological process efficiency. The relevance of this research is due to the fact that modern technological processes in agriculture cannot be implemented without the practical use of plant protection measures, in particular, the chemical method, which consists in the use of chemical compounds against pathogens of plants, pests, weeds, and is the most common, contributing to a significant increase in the yield of cultivated crops and labour productivity in agricultural production. All this, in our opinion, indicates the high practical significance of the results obtained.
