Today the trend in the digitalisation of all economic spheres is particularly noticeable. Agriculture is no exception here. According to forecasts, the agribusiness transition to Industry-4.0 will increase the yield by 10 %. One of the digital design and modeling technologies is the use of digital analogues of objects or processes. This technology can be applied to an agricultural tractor or other power device. Using this approach will allow you to plan the annual load of machines, taking into account their maintenance condition, efficiency of use, etc. Also such a system will allow to choose the optimal operating modes of agricultural machinery, which in turn will increase its capacity, yield and reduce losses.

Service Strategies

When merchants enter hybrid e-commerce platforms (such as JD.com and Amazon), they will face issues such as which sales methods to choose and whether to use platform logistics under different power structures. Different sales methods and logistics service strategies have resulted in three operating modes: (a) resale mode, marked as A, (b) agency + no-platform logistics, marked as B, and (c) agency + platform logistics, marked as C. This paper constructs an analysis framework composed of an e-commerce platform and a merchant to explore the optimal operating mode. The game models of the three modes are first constructed, and then, the equilibrium results are compared and analysed. Based on the results of comparative analysis and considering the dynamic game between the e-commerce platform and the merchant regarding sales methods and logistics service strategies, the optimal operating mode is determined. The results show that when the platform has absolute power, mode C is optimal for it. When the logistics service sensitivity coefficient and market size are both large, the best for the merchant with absolute power is mode B. In addition, if neither of them has absolute power, only when the merchant first decides the logistics service strategy, then the platform decides the sales method; the best for both parties is mode B; otherwise, the best is mode A. This research has generated new insights and has practical management significance, which can provide guidance for merchant and platform decision-making.

Abstract The purpose of this work is to develop a dosing system that provides high-quality bunch planting of watermelon seeds with a given seeding rate and their uniform distribution over the plant nutrition area. It is important to know how many seeds it is needed in the bunch in order to provide the required number of plants in a certain plant nutrition area. The method to achieve this goal is to determine the optimal operating modes for the seeding device, in which the dosing system would supply the seed to the bunch without gaps, searching for dependencies that can determine the required number of the sown seeds in the bunch, taking into account their germination and the number of plants specified by agrotechnical conditions in every bunch. Based on the obtained dependencies, determining the probability of bunches with various numbers of plants, while sowing four seeds in the seedbed with maximum field germination, the design of experimental seed discs is proposed, allowing bunch planting and germination due to easy destruction of the soil crust. At the same time, optimal use of the nutritional area for plants, and, consequently, an increase in the yield of the sown crops is ensured. Experimental seed discs with a group arrangement of suction holes (four cells each) will provide bunch planting of watermelon seeds in accordance with agrotechnical requirements.

Modern Technologies

Modern technologies for applying artificial shells are based on the principles of rolling or granulating with subsequent drying. This technology does not allow to get a gas - permeable porous shell, which often leads to the death of seeds during the formation of the shell, storage and transportation, and slow growth at the early stages of plant development. The aim of the research is to develop a new method and device for pre-sowing treatment of agricultural seeds, which can increase their germination, germination energy and ensure crop growth. A distinctive feature of the new method is that the shell is formed not by rolling, but by molding around the seed, followed by drying in a soft mode. This will form a porous, gas-permeable structure around the seed. Based on the mathematical description of the processes occurring during the introduction of seeds into the nutrient medium, the design calculations and calculations made a laboratory stand for the study of the seeds coating with a protective and nutritious shell, which consists of a mixing, sealing and seeding nodes. A series of experiments was conducted to study the operation of the stand in various modes. Optimal operating modes are identified.

Results of experimental studies of the potato digger with rotary separating web are published in this article. The main challenge is experiment testing of the kinematic parameters of the proposed design which were calculated theoretically. Special attention is paid to definition of optimal operating modes of the rotary separation web. Rational kinematic parameters of the potato digger are determined by the analysis of the results of experimental studies.

This article examines the process models of business processes of gas distribution stations (GDS), which would be a symbiosis of digital twins and artificial intelligence. The basis of the system could be a mathematical model of the plant, taking into account the operating parameters, which is able to determine the response of the equipment to various operating loads and predict the periods of trouble-free operation. The system could also provide for methods of simulation of physical processes to determine the optimal operating modes and boundary conditions for their operation. Reengineering means that we are moving to the operation of the main GDS equipment according to the actual technical condition, and not according to the operating time, as is happening now.
