Analysis of functional requirements for the system of reclamation treatment of slopes and plains lands

Over-consolidation of cultivated slope and plain lands is one of the main reasons reducing the cultivated crops yields. It also contributes to the negative effects of surface runoff and deflation, especially in southern Russia, an erosion-prone region of our country. The widespread use of plowing, no-till and intensive use of energy-intensive machinery in fields leads to accelerated land degradation. Thus, there is a constant loss of productivity, the yield shortfall amounts to an average of 25-30%. The influence of current environmental and agrotechnological conditions requires the use of chiseling with advanced energy-saving multipurpose tools capable of processing both plain fields and slope lands. The peculiarities of slope lands cultivation impose specific requirements for raising agricultural crops on slopes without manual labor using. But, today, modern designs of tillage implements do not fully solve problems in cultivating plains and slopes in the current climatic situation in southern Russia. There is a need to create a multipurpose energy-saving tool for chiseling of plains and slopes based on conceptual design. The use of conceptual design methods enables to formulate a more rational way to create tillage implements. The methodology for developing an innovative system for reclamation of cultivated slope and plain lands (SRCSPL) is based on the modern information technology development in accordance with the accepted concept of the unity of all the life cycle stages. When modeling the system evolution, the UML use case diagram is a fundamental dynamic diagram. The article presents a diagram of use cases or options for the SRCSPL using, which shows the interrelationships of functional requirements in the form of goals initiated by specific participants in the process: the customer (land user), ecologist, economist, mechanic operator, to create the SRCSPL. Using a compromise and taking into account financial and technological constraints, we determine various combinations to achieve the global goal - “Increasing the efficiency of the SRCSPL functioning”.
