Abstract. Existing approaches to assessing the sustainability of an economic system that is in a state of reform or in a transition period (industry, region) have some disadvantages. Some approaches can be applied only to static systems or systems with a stable structure, while others do not have predictive properties. Therefore, there is a need to develop a methodology that can provide a more accurate conclusion about the sustainability and prospects of an industry or region undergoing organizational reform. The authors proposed methodological approaches to assessing the level of stability of the functioning of the region and the industry in terms of deregulation, based on existing ratings, differing in the use of econometric methods.
Abstract. Building and developing an affordable housing market is a huge challenge for Russia's national economy. Today, the housing construction industry finds itself in a situation torn by a conflict caused by the simultaneous needs to minimize the housing construction costs in order to make housing more affordable for Russians and to increase the energy efficiency of the housing projects, which is associated with additional costs for developers. To find solutions to this contradictory situation, one needs new theoretical and practical approaches and economic tools. The global economic trend of managing goods and services on the basis of the value of goods and services over the life cycle is also manifested in the construction industry in Russia. The problem of forming a new economic thinking in the housing sector predetermines the perception of the value of housing not only as the price of purchased real estate, but as the equivalent of the total cost of ownership of real estate throughout its life cycle. This approach allows to compensate the initial rise in the cost of construction resulting from the introduction of energy-efficient technologies by savings in the operational phase of the life cycle of the property. In this regard, management of the total cost of real estate ownership based on energy modeling is of high research and practical relevance.
The paper studies changes in methodology for appraisal activity that pursues effective management of sustainable and breakthrough growth in economy and social sector through ensuring priorities of the National projects and resource efficiency when evaluating cost of life cycles as a result of value-centered management. Gravity to tackle economic problems of need to kick-start innovative high-tech investment cycles for the development of industries, enterprises and investment projects, built upon updated methodological framework for appraisal activity, defines the relevance of this study. In addition, a model to formalize processes of appraisal and management of costs and expenses in economic systems on the basis of life cycles of goods, products and services is proposed to be used as a bedrock of appraising concept. The goal of the study is to develop a set of sound methodological solutions for design of concepts of value appraisal of life cycles in appraisal activity in Russia. It should be done to make its reformation sufficient for cost management of sustainable and breakthrough growth of the country in social and economic fields through effective implementation of the National projects and resource efficiency. The objects of this study are processes of theoretical elaborations and concept-based approaches to the modeling of methodological grounds for value appraisal and management of life cycles of goods within the implementation of national projects by minimizing the cost of their cycles, lifecycle contract, total expenditures and ownership cost of life cycles based on the energy efficient and high-technology products. The applied methods dwell on a comprehensive approach which comprises analysis and synthesis, logical analysis, expert-based approach, methods of economic and mathematical modeling and forecasting.
Abstract. In the production of building structures for high-rise buildings, the dangerous and harmful factors of foundry production include high concentrations of dust and harmful gases released at various stages of the process. Disperse and elemental compositions of dust determine the hygienic state of the working area of the foundry. According to experts, the presence of dust of less than 10 microns in size in the air increases the danger of getting occupational diseases, such as pneumoconiosis (silicosis), bronchitis, dermatitis, conjunctivitis. The determination of the granulometric composition of the powder sample provided was carried out by the laser diffraction method realized on a laser particle analyzer Fritsch NanoTec «ANALISETTE 22».
