Ship recycling at the end of its useful life presents significant environmental and health challenges due to the presence of hazardous materials, such as asbestos and synthetic vitreous fibers (SVFs). This study aimed to convert SVFs and asbestos into safe, reusable co-products by incorporating them into a glassy matrix. The materials were melted at 1200 °C for 1 h with utilization of niobium pentoxide (Nb2O5) to lower fusion temperatures. Samples collected from an offshore vessel and platform being recycled in Rio de Janeiro, Brazil, were analyzed using energy-dispersive x-ray spectroscopy (EDS) and scanning electron microscopy (SEM), revealing the presence of SVFs but not asbestos. Seven types of glass were produced, with their non-crystalline, glassy nature confirmed by the presence of an amorphous halo in X-ray diffraction (XRD) and a glass transition observed in differential scanning calorimetry (DSC). These findings demonstrate the potential to transform hazardous waste into value-added products, advancing a circular economy in ship recycling operations. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2025.

作者： Taís Bisognin Garlet Fernando de Souza Savian José Luis Duarte Ribeiro Post-Graduate Program in Production Engineering at Federal University of Rio Grande do Sul Osvaldo Aranha avenue No. 99 5th floor ZIP code: 90035-190 Porto Alegre Rio Grande do Sul Brazil Post-Graduate Program in Production Engineering at Federal University of Santa Maria Roraima avenue No. 1000 building 7 room No. 302 ZIP code: 97105-900 Santa Maria Rio Grande do Sul Brazil

Photovoltaic generation is essential to face global energy challenges and promote a transition to a sustainable future. However, as technological transformations and economic progress occur, rivalry in the photovoltaic industry intensifies. Given the different competition scenarios observed throughout the photovoltaic value chain, a deeper analysis of inter-organizational relationships is necessary to develop market strategies to increase the number of decentralized photovoltaic systems. Therefore, this article explores the dynamics of inter-organizational relationships in the Brazilian photovoltaic value chain and how they can impact the development and competitiveness of the sector. Based on literature analysis and expert interviews, drivers and barriers to establishing collaborative and synergistic relationships to expand the photovoltaic market are discussed. The results highlight the complexity of inter-organizational relationships, which manifest themselves especially as strategic partnerships, technical relationships, and commercial relationships. Relationships emerge as crucial elements to guarantee the quality of products and services, operational efficiency, competitive deadlines, and fair prices. The barriers are fierce competition, dependence on imported inputs, lack of loyalty, and logistics network deficiencies. The findings showed that involvement and synergy between different stakeholders help develop dynamic capabilities and drive mechanisms to implement resources and relationships critical to creating value and competitive advantage. Additionally, the insights can guide the formulation of actions and strategies to promote the advancement of core technologies in emerging countries’ PV industry.

Hoshin Kanri and A3: a proposal for integrating variability into the policy deployment process

引用

TQM Journal 2019年第2期31卷 118-135页

作者： Tortorella, Guilherme Cauchick-Miguel, Paulo A. Gaiardelli, Paolo Federal University of Santa Catarina Florianopolis Brazil Department of Production and Systems Engineering Federal University of Santa Catarina Florianopolis Brazil Post-Graduate Program of Production Engineering Universidade de Sao Paulo Sao Paulo Brazil Universita degli Studi di Bergamo Bergamo Italy

Purpose: The purpose of this paper is to propose a methodology to support the Hoshin Kanri (HK) process taking into account the variance of senior managers’ perspective regarding the relationships among objectives, key performance indicators and continuous improvement (CI) projects. Design/methodology/approach: A four-step methodology incorporates the A3 report into the HK, whose deployment was weighted by the variability among managers’ perception about the importance of each decision. This methodology was applied in a market-leader Mexican auto parts manufacturing company that is undergoing a Lean Manufacturing (LM) implementation. Findings: The results indicate that the proposed methodology provides an easier approach to consolidate different perspectives and weight the importance of CI projects. Moreover, it minimizes the possibility of managerial conflicts or the influence of a determined senior manager on others’ opinions during the deployment and prioritization. Practical implications: This work may be of great interest to managers, consultants and professionals who deal with the implementation of LM and wish to prioritize the importance of CI projects within the perspective of HK. Originality/value: HK provides a systematic approach to integrate strategic management with daily routine management through an adequate deployment of organizational policies to all levels. However, companies usually struggle with several issues such as the style of senior managers and consensus establishment among different opinions, which emphasizes the relevance of the proposed methodology in this study. © 2018, Emerald Publishing Limited.

Saturated hydraulic conductivity (KSat) is a key soil attribute that influences hydrological processes at multiple scales. It is well known that KSat is difficult to measure in the field. Field KSat measurement requires time and expensive equipment, skilled labor, and due to the variability of KSat, many samples are required. Artificial neural networks (ANNs) are powerful non-linear mathematical models that can estimate KSat from different soil and environmental input variables as well as using dimensionless variables generated using database resizing techniques via principal component analysis (PCA). Our main goal is to construct artificial neural network models for predicting KSat using soil and different land uses as input variables at a watershed scale. The study area is the Eller Creek watershed of about 0.7 km2 in southern Brazil, in which we established an experimental grid of 178 sampling points. Data of soil bulk density, total porosity, microporosity, macroporosity, soil organic carbon content, sand, silt and clay, and KSat were determined at each point in the 0-20 cm layer. A land-use map was derived from satellite images and used to identify the land use around each soil sampling point. PCA was applied to the original dataset and two selected PCs were included as input variables for ANN modeling. Our results suggest that PC inclusion as input parameters, collectively or individually, combined with the original data, increased the performance of the analyzed ANN models, when compared to similar models using only the original data and without PCs. The use of ANN models showed that the variation of KSat in the ECW watershed is not only associated with soil hydrological and environmental covariates, but also to PCs which are orthogonal linear recombinations that encapsulate the main sources of variation of the original datasets. © 2024, The Authors.

There is a growing concern about food production, the rational use of energy, and the impacts caused by anthropogenic greenhouse gas emissions on transport systems. With this concern in mind, the objective of this paper is to discuss the economic and environmental performance of different combinations of cargo vehicles. To do so, we explored the flow of soybean from Mato Grosso state to the ports. The results show that the combination of the stump semi-trailer presented the best economic performance, while the combination of the 'rodotrem' semi-trailer presented the best environmental performance. Moreover, this work points out the importance of the quality of the highways on the economic and environmental performance of soybean transportation. © Interconnected Supply Chains in an Era of Innovation - Proceedings of the 8th International Conference on Information Systems, Logistics and Supply Chain, ILS 2020.

Industry 4.0 has drawn the attention of researchers around the world for its potential ability to increase competitiveness of the companies that can use it. Although much research has emphasized the technological aspect, little attention has been paid to the challenges and opportunities that the companies which intend to implement it expect to face. Based on secondary data this paper involved a research made with 135 companies in Ireland, 246 in Brazil and 305 in Argentina, to study the expected benefits and internal and external barriers that these 686 have in relation to the implementation of Industry 4.0. The practical implication and originality of this study is to present common points and some differences that these companies have, so researchers can guide their studies to try to overcome the main barriers, improving potential opportunities and helping to link research with practice more effectively. © 2019, Computers and Industrial engineering.

The number of journals, and consequently the number of papers, has grown significantly, which makes it necessary to use suitable tools in systematic literature reviews. Several methodologies have been proposed for this purpose, and one of these methods is the index calculation used to rank the papers in order of importance. This study proposes a new index called the Normalized Index for Ranking Papers to rank the papers in a systematic literature review, which is considered mainly indicators provided by the Centre for Science and Technology Studies journal indicators. For this index calculation, importance weights are assigned by the researchers, and the indicators used in the index are normalized. For ranking the final portfolio, the proposed method considers a weighted average of indicators (impact factors) in which the paper was published and a value that represents approximately the number of citations per year. The journal self-citation index benefits the journals with lower self-citation practices. A Systematic Literature Review (SLR) was carried out to analyze the final portfolio's results involving Multi-criteria Decision Analysis in airports. The indicators normalization enables the importance of each metric to be decided by the researcher according to the choice of the weights, not by the difference in the indicators’ magnitude. The importance of an article can be proved initially by the journal indicators in which the paper was published and by citations per year. © 2024 The Authors

Saturated soil hydraulic conductivity (KSat) is a key soil attribute that affects hydrological processes in the soil surface layer. It is well known that KSat is difficult to be obtained in the field, requires time and expensive equipment, skilled labor and, due to its variability, requires many samples and can hardly be extrapolated. Artificial neural networks (ANNs) are powerful no-linear mathematical models to estimate KSat from different soil hydro-physical and environmental input variables as well as by using dimensionless variables generated by database resizing techniques from principal component analyses (PCA). The present study aimed to construct artificial neural network models for predicting KSat using soil attributes and different land uses as input variables at a watershed scale. The study was carried out in the Ellert Creek watershed of about 0.7 km2, Brazil, in which an experimental grid consisted of 178 sampling points was established. Data of soil bulk density, total porosity, microporosity, macroporosity, soil organic carbon content, sand, silt and clay, and KSat were determined at each point in the 0-20 cm layer. A land-use map was derived from satellite images and used to identify the land use around each soil sampling point. PCA was applied to the original data set and selected PCs were used as input variables for ANN modeling. Two PCs were selected and the results suggest that their inclusion as input parameters, both or individually, combined with the original data, increased the performance of the analyzed ANN models, when compared to similar models with only original data and without PCs. The use of ANN models showed that the variation of KSat in the ECW watershed is not only associated to soil hydrological and environment covariates, but also to PCs which are orthogonal linear recombinations that resume the main sources of variation of the original data sets. © 2023, The Authors.
