U. Uzbekov, A. Arifjanov, L. Samiyev - “TIIAME” National Research University, U. Nuriddinova - Karshi Engineering-Economics Institute Abstract Due to exponential changes in climate and land use, spatial and temporal variability in the global water cycle are being reported by many studies. Human activities are affected by rapid social and economic developments, consequently, water has turned into the most demanded resource which leading to severe water shortage around the world. In this research, systematic review method was used to analyze the recent climate and hydrology studies, and besides, SWOT analysis was performed to see Strength, Weakness, Opportunity and Threat of modelling studies, hydrological modelling in particular. The results showed that the studies were carried out in the various river basins, lakes and watersheds, where mostly impact of climate change on water resources was investigated using hydrological models. It was reported that limitation of the modelling were issues with data sufficiency, software skill requirement and misinterpretation of model results by the end users. Moreover, modelling holds some threats that when there is uncertainty in input data that leads overestimated values in model simulation. Keywords: hydrological modelling, hydrological cycle, SWOT analysis, climate change, river, reservoirs.

Sh.Ubaydullaeva – c.t.s., associate professor, TIIAME National Research University Abstract In connection with the problems of development and implementation of perfect automatic and automated control systems for complex technological processes based on modern information technology tools, the development of research methods for multidimensional nonlinear discrete control systems is of particular relevance. The variety of these systems is due to the types of modulation, non-linearities, modes of operation of impulse elements, characteristics of continuous parts. The article deals with the problems of modeling and research of one-dimensional and multidimensional pulse-frequency systems with delay based on the use of dynamic graphs. One of the key points in solving the problem is an approach based on the maximum consideration of the physical features of these systems. Given the structural complexity of systems, it is necessary first of all to establish the possibility of decomposing the system into simpler subsystems. Then the study of the system can be reduced to the study of individual subsystems and the nature of their interaction, that is, to the determination of the properties of the system as a whole by the properties of its elements. Systems with frequency-pulse modulation are essentially non-linear systems. The topological method based on dynamic graph models allows solving the fundamental difficulties of studying nonlinear discrete systems with delay, allows clearly and strictly formalizing their description, and makes it possible to obtain effective algorithms for analyzing one-dimensional and multidimensional systems of this class. The article presents an example of using the obtained algorithm. Keywords: nonlinear discrete system, frequency pulse modulator, frequency-pulse system with delay, dynamic processes, graph model

Q.A.Nosurullaev – PhD student; I.O.Yunusov – PhD, Department of Economics, “TIIAME” National Research University Abstract In modern society, insurance covers almost all areas of life and business - from life and health insurance, to the use of material, financial, vehicles, structures that carry out many types of business activities, including the agricultural sector. It is no exaggeration to say that the development of insurance institutions reflects the level of economic culture of society. Because this allows to create a complete system of protection against risks that inevitably arise as a result of the influence of natural and technical factors. Therefore, determining and analyzing the demand for insurance provides the provision of alternative insurance services, creates the conditions for the protection of many socio-economic subsystems of society from various risks, and provides sustainable development. It should be noted that modern international insurance marketing already has a sufficiently developed set of tools that allow establishing effective and long-term relationships between consumers and service providers. However, these tools are aimed at ensuring the sale of various insurance products, and their attractiveness mainly depends on the profitability of the price offer, and are not aimed at developing an insurance culture, implying that certain types of activities are too risky without insurance. These types of activities include local agriculture, which is carried out in extremely unfavorable natural and climatic conditions. These measures do not always achieve their goal due to the fact that consumers misperceive the importance of this type of expenditure. Therefore, through marketing, it is necessary not only to encourage the purchase of insurance services, but also to form the idea that it is a correct rule of economic behavior, a mandatory institution for the implementation of agribusiness.

B.Nosirov – Andijan Institute of Agriculture and Agro technologies Abstract Today in Uzbekistan it is necessary to bring pedigree animals not only for the purposes of commercial production, but also for use in the field of selection of science. At the same time, the study of the level of import of breeding materials from different regions of the world and their adaptation to the regions of the republic will create great opportunities for the development of the cattle industry in the future. Especially in rural areas, the demand for machinery and equipment for processing dairy and meat products, components and spare parts and mini-shops requires the promotion of imports at the state level. Livestock sector plays an important role in generating income for the rural population of the country, so the problems and prospects of its development are a priority of Uzbekistan's agrarian policy. Currently, more than 90 percent of livestock production is grown on small dekhkan farms. The main problem of the industry is the imbalance between the number of livestock and the amount of resources available to feed them.
