Many tasks in economic research are based on arithmetic calculations of indicators that reflect the state of economic development. The general incompleteness of publicly available data, designed to solve such problems, has led to the emergence of numerous decision support systems based on fuzzy arithmetic. The article presents a study on the approach aimed at integrating fuzzy information about economic indicators into economic models. The definition of arithmetic operations on fuzzy values is given, and the methods of obtaining the resulting fuzzy indicators with the help of some software tools are considered. Analytical and numerical methods of obtaining the resulting indicators in the form of fuzzy numbers are described and analyzed. A direct calculation algorithm for all arithmetic operations is proposed, utilized, and used for the evaluation of resulting indicators. Also, analytical and numerical methods for obtaining fuzzy results are considered in the article, and some of them are proposed for utilization. On the example of economic indicators used in the labor rationing, the results of an evaluation of some indicators for a technological operation in the form of fuzzy numbers were obtained by different methods and compared. The practical recommendations, given in the article, on the use of fuzzy arithmetic in decision support systems outline the directions of further research.

The article contains a review of the contemporary research in the field of economics of happiness. Economics of happiness deals with correlation between the subjective notion of well-being and happiness with ones life (happiness level) and economic indicators. The author considers the correlation of economic and noneconomic factors. The last ones —  such as education and health — also affect the level of happiness. The author dwells upon the following questions: research methodology in economics of happiness, correlation between subjective notion of well-being and happiness with ones life and economic performance on micro- and macrolevels.

Dewaxing Process

Variants of the intensification of the solvent dewaxing process, which increase the yield of base oils, are described. One of the promising ways to improve the technical and economic indicators of the dewaxing process is the use of modifying additives. The work shows that the introduction of a polymer additive requires a decrease in the filtration rate and, accordingly, an increase in the performance of the dewaxing unit. This results in a petrolatum with a reduced oil content, which is a qualifying factor for the production of high-melting ceresins, protective-wax components, and lubricants for various purposes.

First Time

The study was targeted at developing a methodology for constructing a macroeconomic performance index at a provincial level for the first time in Vietnam based on 4 groups of measurements: (i) Economic indicators; (ii) oriented economic indicators; (iii) socio-economic indicators; and (iv) economic - social – institutional indicators. Applying the methodology to the 2011 - 2015 empirical data of all provinces in Vietnam, the research shows that the socio-economic development strategy implemented by those provinces did not provide balanced outcomes between growth and social objectives, sustainability and inclusiveness. Many provinces focused on economic growth at the cost of structural change, equality and institutional transformation. In contrast, many provinces were successful in improving equality but not growth. Those facts threaten the long-term development objectives of the provinces.

Subject. We investigate trends in the development of the largest steel companies in the Russian Federation. Objectives. The aim of the study is to conduct an industry-wide analysis of the production and economic activities of the largest domestic enterprises operating in the iron and steel industry. Methods. The study employs methods of comparative and system analysis, graphical and statistical methods for data processing. Results. We present the analysis of main production and economic indicators of the leading steel producers of the Russian Federation, i.e. NLMK, Severstal, MMK, and EVRAZ. The paper reveals their current status and key development trends. Conclusions. The largest Russian steel companies face serious challenges in both the domestic and foreign market. Competitive interactions in the domestic market as to the sale price of rolled metal and the share of presence are particularly sensitive. The threat of reduced supplies to export markets is also significant for Russian steel producers. It may entail insufficient utilization of capacities and potential loss of added value. The companies mainly export semi–finished goods and hot-rolled flat products, i.e. low-added value products. Products with high added value are usually delivered to the domestic market.
