Komarysta B. Modeling and calculation of indicators of sustainable development for technological systems

IThe thesis is focused on assessing the impact of the life cycle of product system on the environment and human health. The methodology was proposed to assess the impact of the product life cycle based on five components. The components were converted to a single-dimensional rating scale from 0 to 1 using the Harrington desirability function. The unitary sustainable resource consumption index, which is derived from sustainable resource consumption factor to assess the level of resource use was worked out. The unitary index of industrial energy intensity of product system to account the energy component was formed on the basis of State Standard of Ukraine DSTU 3682-98 of energy conservation. Unitary index of industrial pollution involving the environmental component is based on normative maximum allowable concentrations. Unitary index of industrial pollution considers air pollution, surface water and soil contamination. Unitary index of efficiency of natural resources use takes into account commodity costs, the time of product beneficial use, the time of decay and the possibility of recycling the product formed after the disposal of waste. The unitary product hazard index is based on international standard indicators to assess damage to the product life cycle. The unitary index of harmful impact of the product takes into account four categories of protection: "Human Health", "Ecosystem", "Climate" and "Resources". The multilayer perceptron neural network was developed to get quick answers in the form of classification of the potential environmental impacts for a product system throughout the life cycle of the product by five-level evaluation scale. The environmental sustainability was assessed for two types of cement. The resource consumption sustainability was evaluated for the production of rolled roofing materials, as well as the sustainability of the life cycle of winter wheat using nitrogen fertilizer was compared.
