This paper aims to overcome the inability of both comparing loss costs and accounting for production resource losses of Overall Equipment Effectiveness (OEE)-related approaches.

The authors conducted a literature review about the studies focusing on approaches combining OEE with monetary units and/or resource issues. The authors developed an approach based on Overall Equipment Cost Loss (OECL), introducing a component for the production resource consumption of a machine. A real case study about a smart multicenter three-spindle machine is used to test the applicability of the approach.

The paper proposes Resource Overall Equipment Cost Loss (ROECL), i.e. a new KPI expressed in monetary units that represents the total cost of losses (including production resource ones) caused by inefficiencies and deviations of the machine or equipment from its optimal operating status occurring over a specific time period. ROECL enables to quantify the variation of the product cost occurring when a machine or equipment changes its health status and to determine the actual product cost for a given production order. In the analysed case study, the most critical production orders showed an actual production cost about 60% higher than the minimal cost possible under the most efficient operating conditions.

The proposed approach may support both production and cost accounting managers during the identification of areas requiring attention and representing opportunities for improvement in terms of availability, performance, quality, and resource losses.

Introduction: The notion of job losses during energy transition phases and their influences on fossil fuel economies have been debated in various aspects. Meanwhile, unemployment and poverty have been critical economic challenges for many developing countries, even the resource-rich countries in the Middle East. Concurrently, no country so far is poverty-free and has not entirely fulfilled Sustainable Development Goals (SDG) Nos. 1 and 8, as many resource-rich countries account for the significant global poverty and unemployment, such as Nigeria, Iraq, Yemen, and Venezuela.

Purpose: The issue of green transition has created new fears for the job market in the fossil fuel economies, where the lives of many people could be mainly affected. This study investigates the macroeconomic challenges of green transition and the macroeconomic consequences that fossil fuel economies will deal with.

Methodology: This study follows content analysis and a desk-search review of job loss during the green transition in the context of fossil fuel economies. In addition, the descriptive analysis is just a clear understanding of the fundamental review of the topic that will lead to another cross-country analysis study based on in-depth knowledge and analysing data.

Findings: The European Green Deal (EGD) will have profound economic, social, and political implications for fossil fuel-dependent economies for various reasons. First, fossil fuel economies are less diversified; the economy depends on a single commodity; the systems must be developed and people must prepare for a quick economic transition.

This paper presents a new and well-structured framework that aims to assess the current environmental impact from a Greenhouse Gas (GHG) emissions perspective. This tool includes a new set of Lean Key Performance Indicators (KPIs), which translates the well-known logic of Overall Equipment Effectiveness in the field of GHG emissions, that can progressively detect industrial losses that cause GHG emissions and support decision-making for implementing improvements.

The new metrics are presented with reference to two different perspectives: (1) to highlight the deviation of the current value of emissions from the target; (2) to adopt a diagnostic orientation not only to provide an assessment of current performance but also to search for the main causes of inefficiencies and to direct improvement implementations.

The proposed framework was applied to a major company operating in the plywood production sector. It identified emission-related losses at each stage of the production process, providing an overall performance evaluation of 53.1%. The industrial application shows how the indicators work in practice, and the framework as a whole, to assess GHG emissions related to industrial losses and to proper address improvement actions.

This paper scrutinizes a new set of Lean KPIs to assess the industrial losses causing GHG emissions and identifies some significant drawbacks. Then it proposes a new structure of losses and KPIs that not only quantify efficiency but also allow to identify viable countermeasures.

This study aims to determine the best way to apply material flow cost accounting (MFCA) in an SME environment with the goal of visualizing negative product cost during the manufacturing process and pinpointing places where improvements can be made.

This study uses a case study approach to demonstrate the usefulness of the MFCA tool in an SME in India that produces aluminum energy products used in the electrical power sector through gravity die casting.

According to the results, the company’s gravity die casting has a negative product cost margin of 27.38% as a result of MFCA analysis. It is also determined that the negative material cost is Rs. 22,919, the negative system cost is Rs. 462 and the negative energy cost is Rs. 1,069 for processing 300 kg of raw material. The typical monthly raw material processing for this company is 45,000 kg.

This research shows that MFCA’s implementation will improve the company’s environmental consciousness and bottom line. To the best of the authors’ knowledge, this study is the first to implement MFCA in aluminum gravity die casting of electrical parts manufacturing.

This paper aims to propose a methodology for assessing an optimal portfolio of investment instruments that minimise the social costs of decarbonising economic activity while improving the environmental objectives proposed in EU legislation.

The methodology defines the net social cost of decarbonisation related to a portfolio of four instruments: installation of solar PV and wind generation, thermal insulation of households and deployment of heat pumps. The social cost is minimised by restricting it to the minimum level of the targets proposed in the Spanish National Energy and Climate Plan to reduce greenhouse gas emissions, increase generation from renewable sources and reduce energy consumption. The empirical approach also includes differences between regions according to the expected effect for instruments.

The application of this methodology to the environmental objectives defined in the current Spanish National Energy and Climate Plan for 2030 concludes that it is clearly possible to reduce the social cost of decarbonisation while improving environmental performance through a reorientation of investment instruments. In this case, such a reorientation would be based on a minimisation of efforts in thermal insulation of households and a maximisation of measures aimed at the installation of heat pumps.

The paper proposes a novel methodology for a social cost assessment that improves the allocation of a portfolio of environmental instruments. This portfolio could be extended in further work to include instruments related to transport or support for industrial decarbonisation, such as the deployment of renewable hydrogen, among others.

The current literature on energy certificates shows that Energy Performance Certificate labels have an important effect on real estate prices. However, interestingly, the limited studies that address the rental market find significantly lower price premiums than the sales market. The purpose of this paper is to add to this literature, by doing a comparative analysis of price premiums in the sales and rental market in Flanders (Belgium).

This study uses a hedonic regression model to analyze 177,670 real estate listings between 2016 and 2021. The data is provided by Immoweb – the largest online real estate platform in Belgium. The data set was divided in sold and rented properties: the authors evaluated 126,217 sales listings and 51,453 rent listings.

The results confirm that energy efficient properties generate a price premium, but that this premium is significantly larger in the sales market than in the rental market. In addition, the findings indicate that both investors and landlords could benefit strongly from renovating dwellings – especially when renovating from an F label to an A label.

Previous research focuses strongly on the sales market, although in many countries the rental market is similar in size and responsible from much energy consumption. Interestingly, the few studies that are addressing the rental market, find singificantly smaller price premiums than in the sales market. The findings add to this literature tradition and offer a comparative analysis of price premiums in the sales and rental market in Flanders. This allows us to not only show the similarities between both markets but also highlight the differences – creating valuable insights for academia, governments and real estate professionals.

This paper aims to present an overview of permanent magnet linear flux-switching machines (PMLFSM), field excited LFSM and hybrid excited LFSM (HELFSM) topologies as presented in literature for transportation systems such as high-speed trains and maglev systems.

The structural designs of different configurations are thoroughly investigated, and their respective advantages and disadvantages are examined. Based on the geometry and excitation sources, a detailed survey is carried out. Specific design and space issues, such as solid and modular structures, structure strength, excitation sources placement, utilization of PM materials, and flux leakage are investigated.

PMLFSM provide higher power density and efficiency than induction and DC machines because of the superior excitation capability of PMs. The cost of rare-earth PMs has risen sharply in the past few decades because of their frequent use, so the manufacturing cost of PMLFSM is increasing. Owing to the influence of high-energy PMs and magnetic flux concentration, the efficiency and power density are higher in such machines. PM is the only excitation source in PMLFSM and has constant remanence, limiting its applications in a wide speed operation range. Therefore, the field winding is added in the PMLFSM to flexibly regulate the magnetic field, making it a hybrid excited one. The HELFSM possess better flux linkage, high thrust force density and better flux controlling ability, leading to a wide speed range. However, the HELFSM have problems with the crowded mover, as PM, field excited and armature excitation are housed on a short mover. So, for better performance, the area of each excitation component has to compete with each other.

Transportation of goods and people by vehicles is becoming increasingly prevalent. As railways play a significant role in the transportation system and are an integral part of intercity transportation. So, this paper presents an overview of various linear machines that are presented in literature for rail transit systems to promote sustainable urban planning practices.

The author’s interest in studying this topic was inspired by new extraordinary external influences, such as the COVID-19 pandemic and war operations in Europe, which have a direct impact on economic entities and therefore on the economies of many countries in the surrounding area and beyond. The aforementioned external, unpredictable factors appeared unexpectedly. As soon as they appeared, they caused major disruptions in business operations and a crisis on the market, which could not be influenced beforehand, nor could its occurrence be prevented. The impact of external shocks on economies will vary depending on individual countries’ exposure to Russian energy sources, food security, as well as their own economic structure, geographic location, and the degree of flexibility of their public finances. Empirical findings show that there are relatively significant differences in the reactions to the resulting conditions, between large companies that still take into account the durability and publicity of development indicators and others, which are characterized by the absence of a long-term perspective and its reduction to a set of short-term goals that are sought to be achieved in the framework of the visible future. In addition to the standard theoretical analysis, the authors conducted research by surveying selected business entities in Serbia, which provided an insight into the current state of the company and indicated the necessary directions for changes both at the level of business entities and at the level of the entire economy. Based on the conducted research, the authors came to the knowledge that economic entities can solve economic instability by implementing one or more reorganization models.

The purpose of this paper is to examine the relationship between top management commitment and energy management in small and medium manufacturing firms in a developing country context.

This study was executed through a survey of 66 manufacturing firms in Kampala, Uganda. The data collected were analysed using SPSS v.26.

The results show that top management commitment influences energy management. A further probe of its three dimensions of top management participation, top management support and top management beliefs reveals that all of them positively and significantly predict energy management in manufacturing firms.

The current study results were obtained from manufacturing small and medium firms in Kampala, Uganda. Therefore, caution should be taken prior to generalization. Furthermore, this study only focuses on top management participation, top management support and top management beliefs as the dimensions of top management commitment. This study thus provides the foundation for future studies to test other dimensions of top management commitment, particularly in other sectors.

To the best of the authors’ knowledge, this is the first study to examine the contribution of top management commitment dimensions top management participation, top management support and top management beliefs to energy management in a developing country context. Although all dimensions are significant, top management beliefs contribute more to energy management.

This paper aims to model and analyze Jeffery Hamel’s channel flow with the magnetohydrodynamics second-grade hybrid nanofluid. Considering the importance of studying the velocity slip and temperature jump in the boundary conditions of the flow, which leads to results close to reality, this paper intends to analyze the mentioned topic in the convergent and divergent channels that have significant applications.

The examination is conducted on a EG-H_2 O <30%–70%> base fluid that contains hybrid nanoparticles (i.e. SWCNT-MWCNT). To ensure comprehensive results, this study also considers the effects of thermal radiation, thermal sink/source, rotating convergent-divergent channels and magnetic fields. Initially, the governing equations are formulated in cylindrical coordinates and then simplified to ordinary differential equations through appropriate transformations. These equations are solved using the Explicit Runge–Kutta numerical method, and the results are compared with previous studies for validation.

After the validation, the effect of the governing parameters on the temperature and velocity of the second-grade hybrid nanofluid has been investigated by means of various and comprehensive contours. In the following, the issue of entropy generation and its related graphical results for this problem is presented. The mentioned contours and graphs accurately display the influence of problem parameters, including velocity slip and temperature jump. Besides, when thermal radiation is introduced (Rd = +0.1 and Rd = +0.2), entropy generation in convergent-divergent channels decreases by 7% and 14%, respectively, compared to conditions without thermal radiation (Rd = 0). Conversely, increasing the thermal sink/source from 0 to 4 leads to an 8% increase in entropy generation at Q = 2 and a 17% increase at Q = 4 in both types of channels. The details of the analysis of contours and the entropy generation results are fully mentioned in the body of the paper.

There are many studies on convergent and divergent channels, but this study comprehensively investigates the effects of velocity slip and temperature jump and certainly, this geometry with the specifications presented in this paper has not been explored before. Among the other distinctive features of this paper compared to previous works, the authors can mention the presentation of velocity and temperature results in the form of contours, which makes the physical analysis of the problem simpler.
