Keywords: system optimization, constructing and functioning of drainage systems, ecological and economic principles

Abstract

Relevance of research. Land reclamation is important for stabilizing the resource and food security of our state and the world in a whole. Food production security is extremely important in extreme years of weather conditions.

Land reclamation has a high social significance, especially given the global climate change and land policy formation, taking into account European and world experience. Water, hydraulic, agro-technical, and other types of land reclamation require modern innovative solutions. These solutions must be created to achieve sustainable food, energy, the environmental and economic security of the state. Therefore, it is extremely important to change the approaches to constructing and functioning water reclamation facilities. It is also important to improve water management technologies that will be adapted to these changes.

Research goal is to develop a general theory of optimization and development of methods and models for optimal regime, technological and technical parameters of drainage systems on an ecological and economic basis.

Research methods are based on the application of systems theory with system analysis and modeling when developing the approaches to the optimization of regime, technological and technical solutions for constructing and functioning drainage systems on an ecological and economic basis. The system approach includes research of drainage systems as complex natural, technical, ecological and economic systems; research of their elements, laws of functioning and development; decomposition of complex problems of mainly hierarchical nature; application of the methodology of the hierarchy of analysis and synthesis when developing forecasting and optimization models and the methods of their implementation.

Research results and main conclusions. Finding the general (global) optimum for a drainage system on the basis of system optimization is a substantiation of intermediate local optimums for all its basic elements (effect, regime, technology, design). The general principles of construction and realization of complex models of system optimization which include the model of economic optimization have been developed. This model is built on the traditional economic and mathematical approach, and its environmental component determines the correctness of the optimal economic solution. The criteria of economic and ecological optimization of different levels of management decisions in time (1-project, 2-planned operation, 3-management) have been considered. We also present a complex of forecasting and simulation models for long-term forecasting on a multivariate basis, taking into account the variable natural agro-ameliorative conditions of a real object.

Prospects. The application of optimization methods requires a change in the design technology of water reclamation facilities based on the use of a multivariate approach, modern information and computer technologies. The use of system optimization will increase the overall technical, technological, environmental and economic efficiency of constructing and functioning drainage systems.
