Full textAbstract:
The aim of this work is to develop a software to calculate the economic parameters so as to determine the feasibility of a floating offshore renewable farm in a selected location. The software can calculate the economic parameters of several types of offshore renewable energies, as follows: one renewable energy (floating offshore wind—WindFloat, tension leg platform (TLP), and spar; floating wave energy—Pelamis and AquaBuoy), hybrid offshore wind and wave systems (Wave Dragon and W2Power), and combined offshore wind and waves with different systems (independent arrays, peripherally distributed arrays, uniformly distributed arrays, and non-uniformly distributed arrays). The user can select several inputs, such as the location, configuration of the farm, type of floating offshore platform, type of power of the farm, life-cycle of the farm, electric tariff, capital cost, corporate tax, steel cost, percentage of financing, or interest and capacity of the shipyard. The case study is focused on the Galicia region (NW of Spain). The results indicate the economic feasibility of a farm of floating offshore renewable energy in a particular location in terms of its costs, levelized cost of energy (LCOE), internal rate of return (IRR), net present value (NPV), and discounted pay-back period. The tool allows for establishing conclusions about the dependence of the offshore wind resource parameters, the main distances (farm–shore, farm–shipyard, and farm–port), the parameters of the waves, and the bathymetry of the area selected.

The article discusses the economic issues of biodiesel use in agricultural production. Study purpose: determination of the biodiesel production basic economic parameters for agricultural needs. Costs of biodiesel production, formation when using different crops, and costs of replacing traditional diesel fuel are calculated based on an example of a specific enterprise. To solve the problem posed in the study, used specialized software for calculating technological maps in crop production. As a result of the study, it was determined that the own production of biodiesel in the agricultural enterprise conditions is economically justified even at an oil prices low world level. Thanks to the implementation of the investment project to create biodiesel production, it is possible to reduce the cost of fuel and lubricants and thus increase production efficiency. Every year in the conditions of the economy from the use of biodiesel, an economic effect of 2358.7 thousand rubles can be reached.

OBJECTIVE: To extend an existing computer programme for the evaluation and design of shift schedules (BASS 3) by integrating workload as well as economic aspects. METHODS: The redesigned prototype BASS 4 includes a new module with a suitable and easily applicable screening method (EBA) for the assessment of the intensity of physical, emotional and cognitive workload components and their temporal patterns. Specified criterion functions based on these ratings allow for an adjustment of shift and rest duration according to the intensity of physical and mental workload. Furthermore, with regard to interactive effects both workload and temporal conditions, e.g. time of day, are taken into account. In a second new module, important economic aspects and criteria have been implemented. Different ergonomic solutions for scheduling problems can now also be evaluated with regard to their economic costs. RESULTS: The new version of the computer programme (BASS 4) can now simultaneously take into account numerous ergonomic, legal, agreed and economic criteria for the design and evaluation of working hours. CONCLUSIONS: BASS 4 can now be used as an instrument for the design and the evaluation of working hours with regard to legal, ergonomic and economic aspects at the shop floor as well as in administrative (e.g. health and safety inspection) and research problems.

Full textAbstract:
The redundancy is a widely spread technology of building computing systems that continue to operate satisfactorily in the presence of faults occurring in hardware and software components. The principle objective of applying redundancy is achieve reliability goals subject to techno-economic constraints. Due to a plenty of applications arising virtually in both industrial and military organizations especially in embedded fault tolerance systems including telecommunication, distributed computer systems, automated manufacturing systems, etc., the reliability and its dependability measures of redundant computer-based systems have become attractive features for the systems designers and production engineers. However, even with the best design of redundant computer-based systems, software and hardware failures may still occur due to many failure mechanisms leading to serious consequences such as huge economic losses, risk to human life, etc. The objective of present survey article is to discuss various key aspects, failure consequences, methodologies of redundant systems along with software and hardware redundancy techniques which have been developed at the reliability engineering level. The methodological aspects which depict the required steps to build a block diagram composed of components in different configurations as well as Markov and non-Markov state transition diagram representing the structural system has been elaborated. Furthermore, we describe the reliability of a specific redundant system and its comparison with a non redundant system to demonstrate the tractability of proposed models and its performance analysis.

Full textAbstract:
This paper presents an economics-based approach for studying the problem of resource allocation among software development phases. Our approach is structured along two parallel axes: theoretical and empirical. We developed a general economic model for analyzing the allocation problem as a constrained profit maximization problem. The model, based on a novel concept of software production function, considers the effects of different allocations of development resources on output measures of the resulting software product. An empirical environment for evaluating and refining the model is presented, and a first exploratory study for characterizing the model's components and developers' resource allocation decisions is described. The findings illustrate how the model can be applied and validate its underlying assumptions and usability. Future quantitative empirical studies can refine and substantiate various aspects of the proposed model and ultimately improve the productivity of software development processes.

The COVID-19 pandemic that began a year ago was marked by mass isolation of the population and transition to the remote interaction in many areas of human life. In this regard the ability of the domestic vocational education system to fully function through electronic, mobile and remote forms and means of carrying out educational activities is of particular importance. Thus, the problem arises of choosing a software platform for a distance education system that can meet the criteria for organizing and implementing a high-quality and uninterrupted educational process at a university under conditions of distance learning. The article presents the experience of implementing e-learning in the conditions of isolation of students and teachers of Rostov State University of Economics (RINH). The purpose of the article is to analyze the educational capabilities of the Module distance education system based on the experience of its practical application. The research methods used are methods for collecting and accumulating data, methods of assessment and experiential learning. The practical use of the Module system has revealed such shortcomings as the lack of the possibility of conducting interactive lessons in the mode of videoconferencing and the built-in system for testing students' knowledge. Nevertheless, the authors have concluded that the platform is acceptable for solving educational problems. The experience gained in distance learning made it possible to determine the main subsystems that software tools for implementing the distance learning process must meet

More than 10% of the world's working-age population are migrants. Migration issues are particularly relevant in Europe, as 2.7 million people came to Europe in 2019 alone. According to the report “WWWforEurope”, the quantity of research investigating cultural diversity is on the rise, the authors of the report Dohse and Gold (2014) have also noted that cultural diversity affects critical economic variables - economic growth, innovation, and the social welfare. Therefore, Gelfand et al. (2017) argue that research on organizational behavior should include more theories of cultural diversity. There has been little such research in Lithuania, so this article aims to analyze immigrant diversity perspectives in Lithuanian organizations. The qualitative empirical research was conducted using expert interviews. Content analysis was conducted using NVivo software. The results show that Lithuania has a low level of immigrant diversity, but therefore there is currently a growing interest and awareness related to this topic. Immigrant diversity is occurring in international organizations, globally born companies, organizations expanding into foreign markets or organizations founded by immigrants themselves. Two types of organizations (according to immigrant diversity perspectives) were categorized: 1) monolithic organization (this type is more prominent, based on resistance and “discrimination-and-fairness” paradigms and highly related to the cultural context of the country); 2) multicultural organization (focus on “integration-and-learning” and “access-and-legitimacy” paradigms).

Full textAbstract:
Sustainability performance assessment is a challenge for many companies due to the heterogeneity of indicators and the lack of a standardized reporting framework. This paper describes a software solution that simplifies the sustainability reporting process and is useful for decisions concerning sustainable management. We analyzed various indicators from public sustainability reports of five companies and obtained some relevant results using the tool that we developed based on mathematic algorithms and an aggregation model of different indicators. The software application calculates a Global Sustainability Index based on the proposed model of the sustainable organization described in this paper. An optimal solution is very rare in the transition towards the sustainable organization and compromises are required most frequently between environmental, economic and social aspects on the one hand and the expectations of the stakeholders on the other hand. The proposed tool helps users to cope with these challenges and takes into consideration that information is not always available and precise. Another feature offered by the tool is that besides simplifying sustainability performance assessment, it highlights low performance indicators and offers suggestions for improvement based on a genetic algorithm.

Economic liberalization or market reforms have become the buzz word in economics all over the world in the recent years. Among various aspects of economic liberalization, foreign capital, particularly inflow of foreign direct investment (FDI) has been viewed as a main engine for economic development in the world economy. Thus this paper attempts to analyze the impact of FDI inflows on the performance of various Indian industries. Using Panel Co-integration tests namely Pedroni Residual Co-integration, Kao Residual Co-integration test and Johanson Fisher panel co-intergration tests, the presence of co-integration between FDI inflows and the performance variables of selected industries have been tested. The results of the paper reveals that there is a long run relationship between industry performance indicators and FDI only in case of services, telecom, computer software and hardware, real estate and automobile industries and in case of majority of other industries, there is no long run relationship between industry performance indicators and FDI inflow.

Full textAbstract:
Each rational investment decision, including those made by clients with regard to Business Software Systems (BSS) Development and Enhancement Projects (D&EP), should meet two measurable criteria: effectiveness and economic efficiency. However, in the case of BSS D&EP, the assumption concerning the measurability of these criteria is often treated as controversial. Meanwhile, the so-called concept of BSS D&EP Functional Assessment (FA), proposed by the author and verified in practice, allows for using the potential offered by the Functional Size Measurement (FSM) concept and methods in the area of the quantitative evaluation of these two criteria. Thus, the paper aims at presenting and proving the capabilities of using the functional assessment concept in the quantitative evaluation of BSS D&EP effectiveness and economic efficiency. Linking FSM issues with managerial aspects through the FA concept may contribute to a better understanding of the FSM importance, which is still underestimated by business managers, as in the subject literature this issue is usually considered from a technical perspective. Meanwhile, BSS D&EP FA can constitute the basis for rational decisions not only for BSS providers, but also for BSS clients. These issues classify into economics problems of software engineering research and practice.

Full textAbstract:
This article considers methods of state support of young families in Russia and Russian regions. In current socio-economic conditions, young families' support can be viewed as a useful course of state policy. Providing housing to young families allows young adults not only to solve their social, economic, and psychological issues but also creates a background for young families for active participation in societal, economic development, and demographic state policy. Logics of the research is based on that young family support is executed in Russia on federal and regional management levels as part of youth and housing policy.

The objective of this work is to establish a framework for the development of an economic analysis tool for floating offshore wind platforms built in concrete. The operation and usefulness of the beta version of a software, called Arcwind, is explained. It calculates the main economic aspects of offshore wind platforms built in concrete considering different locations in the European Atlantic Arc. This software allows the user to select different input parameters such as: the type of platform, the installation area of the farm, its specific location and in this way create different analysis scenarios. This paper analyzes the case study to install TELWIND® offshore concrete floating platforms in the Canary Islands, in Spain. The software provides data on the main economic parameters of the farm, such as Levelized Cost Of Energy (LCOE), Net Present Value (NPV), Internal Rate of Return (IRR), Pay-Back Period (PBP), as well as the main costs: cost of conception and definition, cost of design and development, cost of manufacturing, cost of installation, cost of operation and cost of dismantling. Using these parameters, a first analysis of the viability of this type of floating technology built on concrete is shown.

Full textAbstract:
Today's consumers increasingly demand products that are produced sustainably and ethically. As a result, businesses need to address sustainability and social responsibility issues and find a proper balance between people, planet and profit (PPP) aspects of their production chains. Software tools can play an important role in mapping out the current state of PPP aspects along the production chain, and in the design and evaluation of improvement options. There are indeed many tools that are claimed to be useful for sustainability and social responsibility considerations. Yet, a tool that addresses all three aspects of value creation holistically and facilitates discussion is missing. In this paper we present the development of such a tool, called QChain. The development of this tool was based on ideas from soft systems methodology and inputs from a multidisciplinary team of experts and managers. The tool is intended to support group discussions, particularly during the early stages of innovation processes aimed at improving PPP aspects of production chains. It enables users to visualize the essential elements of the current production chain showing the current PPP values, and explore and compare possible future production chain scenarios and the corresponding PPP values. QChain's visualization helps discussants get a rich appreciation of the current and future scenarios, while the semi-quantitative 'what-if' analysis and scenario comparison enables them to hold objective discussions.

Full textAbstract:
Purpose – The purpose of this paper is to test a research model in which trust and commitment are mediators between economic and non-economic satisfaction. Design/methodology/approach – The sample for this study comprises a total of 600 small and medium-sized Spanish enterprises from various industrial sectors. A total of 259 usable questionnaires were returned, generating a response rate of 43.2 per cent. The research model is tested with structural equation modeling using AMOS-software. Findings – The empirical findings regarding the studied business relationships confirm the independence between economic and non-economic satisfaction, and the mediating role of trust and commitment. Furthermore, the findings confirm that there is no direct cause–effect relationship between economic and non-economic satisfaction. Research limitations/implications – Numerous inter-organizational studies have tested satisfaction as two separate constructs (economic and non-economic satisfaction). This study goes further by positioning economic satisfaction as a precursor to other more relationship-oriented constructs and outcomes (trust–commitment and, in turn, non-economic or relational satisfaction). Practical implications – Managers should consider economic and non-economic satisfaction as two separate aspects of relationship quality in business relationships. Furthermore, although these aspects appear to be connected, managers should take them into consideration with respect to the levels of trust and commitment involved in business relationships. Managers should be aware that the level of economic satisfaction is an influential precursor to the levels of trust and commitment that in turn impact on the level of non-economic satisfaction as an outcome. Originality/value – This study makes a threefold contribution to existing theory and research. First, it tests the constructs of economic and non-economic satisfaction, indicating satisfactory validity and reliability. Second, it provides empirical support that there is no direct relationship between economic and non-economic satisfaction. Third, the empirical findings also indicate satisfactory validity and reliability, indicating that the constructs of trust and commitment are moderators between economic and non-economic satisfaction.

Full textAbstract:
Multi-objective (energy–economic–safety) assessment of ethyl acetate production involving a heat pump is presented in this paper. The heat pump is designed to intensify ethyl acetate separation and to reduce the total operating cost. Two ethyl acetate production pathways are upgraded using a heat pump, conventional process and reactive distillation column with a separation unit. Detailed process models including the heat pump environment have been compiled and optimized in the Aspen Plus software. Both benefits and drawbacks of including the heat pump in the processes are evaluated using three different points of view: process energy, economics, and safety. As a result, using a heat pump is highly recommended in both conventional process and reactive distillation column with a separation unit. As a higher level of process integration is achieved using a heat pump, economic aspects are improved; however, safety aspects deteriorate. The final decision on the suitability of using a heat pump depends on whether it is proposed for an existing plant, or a completely new plant is designed. In a new plant, the concept of a thermally coupled process (reactive distillation column with a stripper column) has been proven to be the most promising.

The current age and the internet development give raise accessibility to different sources of statistical information. We have more information, though not always it means an increase of knowledge. The great challenge is to turn the available economic data into information and this one into economic knowledge. The possibility of going more deeply into the area of economic forecasting is an interesting focus of knowledge in economic science, supported by the availability of information and specific software. The gross domestic product (GDP) still continues being used as the main magnitude to qualify the economic prosperity of a country or geographic area. It is necessary to interpret correctly the GDP variation in order to extract relevant conclusions for the economic decisions, for the generation and dissemination of knowledge. We review some relevant aspects to consider in the process of regional economic forecasting: forecast combination or to choose the most accurate prediction.

The paper demonstrates the need to consider different sustainability aspects in supply chain redesign and optimization problems. To this end a simulation model of local pharmaceutical business retail is presented as application example. Three different sustainability aspects are considered (technical sustainability, economic sustainability and environmental sustainability) when investigating two different problems: the addition of new pharmacies to the supply chain and optimization of the supply chain routes. The main goals are to understand how new potential customers can be added to the supply chain while reducing the negative impact on the customers’ satisfaction level (technical sustainability), how to optimize the routes followed by each transportation vector (technical, economic and environmental sustainability) and how to compare different solutions in terms of truck fleets in order to reduce CO2 emissions (environmental and economic sustainability).

Full textAbstract:
The article sums up a review of theoretical approaches to the interpretation of economic categories “securities market” and “stock market” and a chronological analysis of the stock market development in independent Ukraine.
It is shown that two general approaches to the interpretation of the above categories exist, legislative and scientific. The latter one can, in turn, be subdivided into narrower approaches: segment approach, with securities market treated as a part of the capital market or financial market; functional approach, with securities market seen as a floor for sales and purchase of securities; normative approach, with securities market addressed as a sophisticated mechanism used to set legal and economic relations between business entities; logical approach, with securities market considered as a set of transaction mechanisms. The authors’ definition of the securities market is proposed: a segment of the financial market, on which interactions between various market actors take place, related with issuance, purchase and sales of securities that have value, circulate freely and certify the relations of co-ownership or lending, with the purpose of effective distribution and rational allocation of financial resources in the socio-economic area of a country with due account for the society’s interests and needs.
The authors’ chronology of the securities market development in Ukraine is proposed, in which six phases are distinguished. The first phase is “reappearance” (1990). The second phase is “formation” (1991–1994), falling upon radical market-driven transformation in the Ukrainian economy. The third phase is “development” (1995–1999): search of the effective owners on the boosting market, setting up a system for control over sales and purchase of securities, creation of investment funds, financial and industrial companies and private pension funds. The fourth phase is “improvement” (2000–2002): creating a system for information support for circulation of securities issued in non-documentary form, and computer software for operating the State registers. The fifth phase is “recovery” (2003–2006): gradual decline of crisis tendencies in the economy along with the recover at the securities market. The sixth phase is “financial globalization” (from 2007 and on). This approach enables to investigate the securities market dynamics over 1991–2018 and give detailed descriptions of each phase with emphasis on core historic event in each.

Full textAbstract:
Purpose Due to the increasing awareness of environmental and social issues, many practitioners and researchers have paid attention to sustainable supply chain management. As the performance of suppliers determines the success of supply chains, sustainable supplier selection becomes more and more important. Existing sustainable supplier selection models evaluated the sustainability of suppliers in three aspects (economic, environmental and social) and assumed that values on different criteria can completely compensate for each other directly. However, in reality, criteria in economic, environmental and social aspects are heterogeneous, and the decision-maker’s preferences on criteria belonging to different aspects are different. In this case, values on criteria belonging to different aspects are not allowed to completely compensate for each other directly. To solve this problem, this paper aims to propose a hybrid sustainable supplier selection approach integrating compensatory and non-compensatory decision rules. Design/methodology/approach In the proposed approach, the compensatory decision method Technique for Order of Preference by Similarity to Ideal Solution is used to evaluate performances of suppliers with respect to economic, environmental and social aspects. The non-compensatory decision method Elimination and Choice Translating Reality is used to evaluate performances of suppliers on sustainable criteria comprehensively. Through the proposed approach, only criteria belonging to the same aspects are allowed to compensate for each other directly. Finally, experimental results show that the proposed integrated approach is effective and efficient to help the decision-maker select optimal sustainable suppliers. Findings This is an original approach that integrates compensatory and non-compensatory decision rules, which can benefit from the two kinds of decision rules simultaneously. The integrated approach can be used as an aid for companies to select the best sustainable suppliers. Originality/value This paper presents an original integrated sustainable supplier selection approach using both compensatory and non-compensatory methods. It can benefit from the advantages of both compensatory and non-compensatory methods. The proposed approach can express preferences of the decision-maker on sustainable criteria sufficiently and maximize economic benefits while meeting environmental needs.

Full textAbstract:
Purpose The purpose of this paper is to investigate additive manufacturing (AM) phenomenon extending previous research results by studying in-depth the economic sustainability of AM technology and bringing out the contextual factors that drive its superior performances in comparison with conventional manufacturing, and justify its adoption in rapid prototyping (RP) from an economic point of view. Design/methodology/approach Data have been collected through a worldwide survey. Respondents were from 105 companies adopting the technology from 23 countries worldwide. Findings The results of this research show that although AM-based prototyping leads to significant cost reduction, it is not as good as conventional manufacturing in terms of the profitability of investment. It also demonstrates how cost reduction depends on production volume and payback period depends on the types of material and scope of AM implementation after controlling for firm size and experience. Research limitations/implications The performance indicator is measured using a Likert scale; however, more reliable conclusion could be made by real amounts. The research also took into account the economic aspects of performance; however, to evaluate the AM technology more comprehensively, other performance measures such as those of social and environmental ones should be considered. Practical implications The paper provides insightful implications for the adoption of AM. In particular, it reveals the contingent performance of the technology in RP. Originality/value This paper contributes to expand the literature by demonstrating how different circumstances affect the performance of AM technologies for prototyping and by linking the operational and organizational factors with its performance.

Full textAbstract:
Electrical energy usage in buildings is a challenging issue because many old buildings were not originally built to achieve energy efficiency. Thus, retrofitting old buildings to net-zero buildings can benefit both the owner and electric utilities. In this study, the BEC (building energy code) software was used to evaluate energy aspects of retrofitted buildings in compliance with Thailand’s building energy code to achieve a net-zero energy building. In addition, economic aspects were also studied to verify the feasibility for a project’s owner to invest in a retrofitted existing building. An existing residential building in Thailand was used as a case study. The results in terms of energy after retrofitting existing buildings into net-zero energy buildings show that the total energy consumption can be reduced by 49.36%. From an economic perspective, the investment cost for a retrofitted building can be compensated by energy saving in terms of discounted payback period (DPP) for approximately 4.36 years and has an IRR (internal rate of return) value of 19.23%. This result evidences the potential in both energy and economy for a project’s owner to invest in a retrofitted existing building in compliance with the building code, with potential for implementation with benefits on both electrical utilities and the project’s owner.

Land reclamation is important in the development of agricultural production for unfavorable climatic conditions. This necessitates the improvement of scientific and methodological approaches to the creation and operation of water management and reclamation facilities, including drainage systems, which are adapted to these changes. Approaches to the type and design of drainage systems based on a combination of a modern progressive optimization approach with the traditional water balance method, hydrodynamic and hydraulic methods are presented. Approaches to the systemic optimization of technological and design solutions for the creation and operation of drainage systems have been determined. It seems that the drainage system is a complex natural and technical ecological and economic system. Finding the general optimum in such a system based on the system optimization consists in substantiating local optima for all its main components of heterogeneous elements in the system effect - mode - technology - design in their interconnection. The practical implementation of a complex of predictive-simulation and optimization calculations in projects for new construction, reconstruction and modernization of drainage systems based on the developed scientific, methodological, information and software can be carried out using the appropriate toolkit, which is CAD and modern BIM technologies. The transition to optimization methods will improve the feasibility and overall technical, technological, environmental and economic efficiency of the creation and operation of water management and reclamation facilities in accordance with modern requirements.

This paper analyzes the impacts of whole solar energy technologies on the economic situation of Afghanistan. Details and positive effects of solar mini-grids which are implemented through the Citizens’ Charter National Priority Program CCNPP in the rural areas of Afghanistan are given as samples of solar energy projects in Afghanistan. The result of this analysis then compared with the fossil fuel electricity that people use in the rural areas of Afghanistan based on the economic effects. The Levelized Cost of Energy (LCOE) for electricity generated through the diesel generator is estimated to be 29 ¢/kWh, which is 3.16 times higher than the cost of electricity produced via photovoltaic (PV) in 9.17 ¢/kWh. The potential for solar thermal as a recently boomed technology in the world is also studied with regard to the climate, economy, and security situation of Afghanistan. The country with 300 sunny days in a year has 1900-2000 kWh/m2 potential of producing electricity through the Concentrated Solar Power (CSP) technology. Using Multi-Criteria Decision Analysis (MCDA) the Parabolic Trough Collector (PTC) is selected as an optimal type of CSP in Afghanistan and a 3.5 MW PTC power plant is simulated via the System Advisor Model (SAM) software. The result of this simulation shows that this novel technology in Afghanistan needs more time and efforts to set as a secure approach of energy

The article is devoted to the currently actual problem of the development and dynamics of the population in urban education from the point of view of spatial-dynamic approximation. The population is divided into different groups according to their economic and individual characteristics. For example, the population can be classified according to genetic and phenotypic characteristics, according to the level of income or education. The question of the peaceful and effective interaction of groups with each other is one of the most important tasks within any urban type of education. The author describes the problem of the interaction of two groups at a qualitative level using a system of two non-stationary nonlinear differential equations of diffusion type. Particular attention is paid to the disclosure of the numerical solution scheme of the selected model: the use of an explicit (in time) difference scheme of the “predictor-corrector” type has been analyzed in detail. In addition, the author conducts a series of computational experiments taking into account the selected assumptions regarding two specific groups of the population. Separately, the solution of the stochastic case and the features of its software implementation are considered. Based on the results of the study, the possibility of the applicability of the new approach to the problems of urban studies is substantiated. This work is the first step in the implementation of a program of using spatial economics to describe real processes in urban formations.

Abstract At the present time, the world’s population is rapidly increasing, and the existing resources, which are limited, are being significantly consumed. Due to this fact, in order to use these resources more efficiently, the concept of planning day by day gains importance in the framework of sustainable development.
