Purpose: This manuscript explores the link between Spare Parts Management and Total Costs of Ownership or Life Cycle Costs (LCC).Design/methodology/approach: First, this work enumerates the different managerial decisions instances in spare parts management that are present during the life cycle of a physical asset. Second, we analyse how those decision instances could affect the TCO of a physical asset (from the economic point of view). Finally, we propose a conceptual framework for incorporating the spare parts management into a TCO model.Findings: The recent literature lacks discussions on the integration of spare parts management with the Total Costs of Ownership (TCO). Based in an extensive literature revision we can declare that the computation of costs related to spare parts management has been neglected by TCO models.Originality/value: The contribution of this paper is twofold. First, a literature review and identification of a series of spare parts management decision instances and its relationship with TCOs is presented in this paper. Second, a conceptual framework is suggested for linking those decisions instances to a total cost of ownership perspective. Some research questions and future research challenges are presented at the end of this work.

Support Tools

The second half of the 20th century was characterized by rapid growth of the urban population and lack of attention to environmental quality in the urbanizes territories. Thus, the development of many cities during that period took place through policies which, over time, resulted in a disaggregated landscape, both in morphological and functional terms. In some cases, these policies have caused the creation of land portions without a specific characterization, and the generation of urban voids that negatively affect the city’s development. To solve this problem, the public administration sectors of many countries are looking for new intervention strategies that are feasible from a social and economic point of view which are able to guarantee sustainable development. From this perspective, the execution of urban regeneration initiatives, including forestation, allows for the improvement of both environmental quality and citizens’ well-being, and promotes economic development. Considering the multiple effects that these initiatives can generate and the limited availability of public and private resources, it is appropriate to use multi-criteria decision support tools through which it is possible to evaluate the interventions’ complexity and best identify the city areas that lend themselves to be recovered and improved through the forestation. The aim of this work is to develop a support tool for public administrations aimed at identifying the optimal forestry projects’ location according to criteria that not only refer to financial type, but also their social, cultural, and environmental nature. Using Discrete Linear Programming algorithms, the model has been tested through a theoretical case study and reveals the advantages and limitations of the model, as well as future research prospects.

The Impact

It is unclear whether the production of biochar is economically feasible. As a consequence, firms do not often invest in biochar production plants. However, biochar production and application might be desirable from a societal perspective as it might entail net environmental benefits. Hence, the aim of this work has been to assess and monetize the environmental impacts of biochar production systems so that the environmental aspects can be integrated with the economic and social ones later on to quantify the total return for society. Therefore, a life cycle analysis (LCA) has been performed for two potential biochar production systems in Belgium based on two different feedstocks: (i) willow and (ii) pig manure. First, the environmental impacts of the two biochar production systems are assessed from a life cycle perspective, assuming one ton of biochar as the functional unit. Therefore, LCA using SimaPro software has been performed both on the midpoint and endpoint level. Biochar production from willow achieves better results compared to biochar from pig manure for all environmental impact categories considered. In a second step, monetary valuation has been applied to the LCA results in order to weigh environmental benefits against environmental costs using the Ecotax, Ecovalue, and Stepwise approach. Consequently, sensitivity analysis investigates the impact of variation in NPK savings and byproducts of the biochar production process on monetized life cycle assessment results. As a result, it is suggested that biochar production from willow is preferred to biochar production from pig manure from an environmental point of view. In future research, those monetized environmental impacts will be integrated within existing techno-economic models that calculate the financial viability from an investor’s point of view, so that the total return for society can be quantified and the preferred biochar production system from a societal point of view can be identified.

Purpose – Spare parts management plays a relevant role for equipment-intensive companies. An important step of such process is the spare parts classification, enabling properly managing different items by taking into account their peculiarities. The purpose of this paper is to review the state of the art of classification of spare parts for manufacturing equipment by presenting an extensive literature analysis followed by an industrial assessment, with the final aim to identify eventual discrepancies. Design/methodology/approach – Not only is the attention put on the literature about the subject, but also on an on-field analysis, that is presented comprehending an extensive survey and two in-depth exploratory case studies. The copper mining sector was chosen being representative for the case of capital intensive plants where the cost of maintenance has relevant weight on the total operating cost. Findings – The paper highlights the status of the scientific literature on spare parts classification by showing the current situation in the real industrial world. The paper depicts the existing barriers that leave gaps between theory and real practice for the application of an effective multi-criteria spare parts classification. Originality/value – The paper provides a review of the theory on spare parts classification methods and criteria, as well as empirical evidences especially for what concern current situation and barriers for an effective implementation in the industrial environment. The paper should be of interest to both academics and practitioners, since it provides original insights on the discrepancies between scientific and industrial world.

Valuation of natural resources, in particular ecosystem resources, occupies one of the leading places in modern economic theory. It should be noted that all methodological and methodical approaches used in world practice to determine the value of natural resources, in their economic essence evaluate each object of using the nature as a commodity that can be bought, sold, leased, etc. This approach is based on an economic point of view and does not take into account the ecological properties of this resource (for example, forest is evaluated exclusively as wood – raw material for the woodworking industry, and its assimilative and oxygen-producing properties are not taken into account). In the article we propose a methodological approach to the valuation of ecosystem assets of territorial communities that provide assimilation and oxygen production services to society, which is based on the ecological-economic point of view. The essence of this method is that the valuation of ecosystem resources is determined by the cost of their ecosystem services that they provide to society throughout its life cycle. Moreover, when carrying out a summary valuation of various ecosystem assets (forest, water, land), the latter must be valued by the same (identical) method. The paper proposes an algorithm and a specific mathematical apparatus that allows to determine the value of any ecosystem resource and on its basis to determine the complex value of ecosystems owned by local communities. Tables of data on the volumes of carbon dioxide absorption by plants of Ukraine, which most intensively assimilate carbon dioxide, on indicators of oxygen release by plants and on the duration of the life cycle of certain species of trees and shrubs. It is these indicators can be used as performance characteristics in the proposed mathematical apparatus in the valuation of ecosystem assets. It is noted that the availability of valuation of ecosystem assets will allow, both at the state and local levels, to make appropriate management decisions on their effective use.

Conflicts between different interests are inevitable in every business organization. Therefore, it is not surprising that the number and intensity of conflicts is sometimes very high. Conflict resolution is a skill without which managers can hardly succeed in their business. The subject of research in this paper is conflict management from a technical and economic point of view. The paper defines and analyzes the notion of leadership, that is, elements and dimensions of leadership, the notion of leader, and theoretical approaches to leadership. In addition to the above, the concept of conflict, more specifically its type, levels of conflict, consequences and causes, and techniques of conflict resolution have been defined and analyzed. An online survey (based on the LinkedIn Business Social Network) was conducted to determine how individuals in a production organization respond and resolve conflicts as well as the results of the same. Based on theoretical scientific approach, the conducted research and the analysis of the results, conclusions and recommendations are given, as well as key questions for future research.

Renewable energy technologies are increasingly integrated into the modernization of multi-apartment buildings, however their benefits are rarely assessed from a complex environmental, energy and economic point of view. The article presents the results of the modernization of a particular apartment building in terms of the production and consumption of energy in a building, from the viewpoint of the life cycle. The benefits of the building’s energy modernization were assessed by introducing active (heat pumps and solar collectors for hot domestic water production) and passive modernization measures. The results show that the integration of heat pumps when electricity is produced from non-renewable energy sources according to the analyzed categories of life cycle analysis is not eco-friendly.

Although leasing can be an interesting financing option from an economic point of view, family businesses are found to be less prone to lease. In this study, we examine the view of the external accountant on leasing as an alternative form of financing within family businesses. After all, as the most trusted advisor, the accountant likely has a significant influence on the financial decisions that are taken within private family businesses. By means of an exploratory qualitative study, we examine what factors influence the advice for a particular financing option and the accountant’s recommendation to lease or not to lease within family businesses. By combining the extant literature with the results of this exploratory qualitative research, we formulate propositions that form fruitful avenues for future research.

Electric mobility is promoted as a future transport option that has environmental and economic benefits and encourages sustainable urban transportation. The aim of this study is to reveal the changes in environmental and economic performance if we switched from internal combustion engine vehicles (ICEVs) to battery electric (BEV) or hybrid electric (HEV) vehicles. Therefore, this research presents a comparative environmental life cycle assessment (LCA) from the Cradle-to-Grave perspective of the vehicles and a Well-to-Wheel analysis of their fuel supply. Moreover, an LCA of a BEV was performed under diverse electricity mix scenarios, which are forecasted for 2015–2050 in Lithuania. From an economic point of view, a life cycle costing was conducted for the same vehicles to estimate the economic impacts over the vehicle life cycles under Lithuanian conditions. The results show that ICEV-petrol contributes the major environmental damage in all damage categories. BEVs with the electricity mix of 2020–2050 scenarios, which are composed mainly of renewable energy sources, provide the least environmental impact. The economic results reveal that BEV and ICEV-diesel are the most cost-efficient vehicles, with the total consumer life cycle costs of approximately 5% and 15% less than ICEV-petrol and HEV, respectively.

ABSTRACT Purpose: Franchising is one of the fastest-growing operating modes in Brazil. In 2014, the Brazilian Franchising Association reported 2,492 active brands in the country. Some theories with an economic point of view, such as the agency theory, plural forms theory, or scarcity principle, explain why companies choose franchising. However, did the decision makers and founders of these franchises decide on this strategy taking only economic reasons into consideration? The purpose of this study is to understand the a priori criteria (prior to the decision) that executives took into account when adopting this strategy and the key motivations for this decision. Originality/gap/relevance/implications: The literature emphasizes the economic reasons for the success of the franchise model, but it does not focus on the founders' motivations when they choose this strategy. This is the gap that this study seeks to address. Dissonance could arise between economic reasons and entry motivations that could result in consequences for the management of new franchises. Key methodological aspects: Ten companies of different industries and different life cycle stages involved with the franchise model were scrutinized using a semi-structured questionnaire based on the literature on decision theory and franchising. Summary of key results: Behavioral factors significantly influence decision makers when choosing the franchise model. Key considerations/conclusions: This study distinguishes the economic reasons from the executives' motivations when choosing the franchise model and highlights the importance of non-economic factors in this decision.
