Maintenance and sustainability: a systematic review of modeling-based literature

PurposeMaintenance is a critical business function with a great impact on economic, environmental and social aspects. However, maintenance decisions' planning has been driven by merely economic and technical measures with inadequate consideration of environmental and social dimensions. This paper presents a review of the literature pertaining to sustainable maintenance decision-making models supported by a bibliometric analysis that seeks to establish the evolution of this research over time and identify the main research clusters.Design/methodology/approachA systematic literature review, supported with a bibliometric and network analysis, of the extant studies is conducted. The relevant literature is categorized based on which sustainability pillar, or possibly multiple ones, is being considered with further classification outlining the application area, modeling approach and the specific peculiarities characterizing each area.FindingsThe review revealed that maintenance and sustainability modeling is an emerging area of research that has intensified in the last few years. This fertile area can be developed further in several directions. In particular, there is room for devising models that are implementable, based on reliable and timely data with proven tangible practical results. While the environmental aspect has been considered, there is a clear scarcity of works addressing the social dimension. One of the identified barriers to developing applicable models is the lack of the required, accurate and timely data.Originality/valueThis work contributes to the maintenance and sustainability modeling research area, provides insights not previously addressed and highlights several avenues for future research. To the best of the authors' knowledge, this is the first review that looks at the integration of sustainability issues in maintenance modeling and optimization.

Evaluation of Collaborative Robot Sustainable Integration in Manufacturing Assembly by Using Process Time Savings

Collaborative robots are enablers of flexibility in the current dynamic and uncertain manufacturing environment. Decision making on its implementation requires technical feasibility, involving productivity and workforce implications that should be faced in an integrated perspective in processes where many components of different materials are assembled in products of increasing diversity and complexity. This study introduces two new parametric models for collaborative robotics, formulated in order to evaluate the differential cost of assembly (economic dimension) and the differential income from taxes that supports short-term workforce displacement (social dimension) in cobot implementation. Updated techno-economical parameters are selected for assessing feasibility ranges of application in different production scenarios. Next, the influence curves of productivity gain for a feasible implementation of cobot establish thresholds for decision making under both criteria. The results show the need for productivity gains that are significantly lower in high-wage scenarios than in low-wage scenarios; however, in a joint approach, breakeven productivity gain is always higher for the social dimension threshold than for the economic requirement of cost-effective manufacturing, with a higher gap in low-wage cases. The detailed analysis of a real case study of cobot implementation for assembly demonstrates the practical application of models and potential for future research.

Happy Sustainability: A Future Quest for More Sustainable Universities

For decades, sustainability researchers have tenaciously insisted on transforming higher education institutions into more sustainable and inclusive campuses. Yet, as the 2030 agenda seems unlikely to be achieved, universities are struggling to meet the fourth Sustainable Development Goal (SDG 4) before the 2030 deadline. In addition, the post-COVID-19 era demands quality and inclusive education that entails care for students experiencing high stress levels. So far, most of the significant achievements are within the environmental or economic dimensions of sustainable development, but strengthening the social dimension is still one pending task. The importance of happiness to sustainability initiatives on campus, and beyond, deserves further research. To this end, this article offers insights into incorporating the sustainability–happiness nexus into sustainable universities to enhance the social dimension of sustainability. COVID-19 reminds sustainability academics and stakeholders that teaching technical and scientific knowledge is necessary to become more sustainable. Still, it is not sufficient to achieve the goals in the 2030 agenda. Providing inclusive and sustainable quality education will be reached when more sustainable universities consider happiness the ultimate goal of human development.

Social Dimension of Shopping Centers Operation: Managerial Perspectives

Shopping centers do not operate in a vacuum but in a society of diverse stakeholders who influence their profit and growth. Therefore, shopping centers management addresses the problem of incorporating social dimensions in their management. The paper aims to identify and evaluate managerial approaches and marketing strategies of shopping centers in the Czech Republic in the context of social dimensions leading to sustainable operation. The research builds methodologically on an online questionnaire survey with top management of shopping centers. It took place at the turn of the years 2019/2020. Out of 88 Czech existing shopping centers, 30 completed responses were received (response rate 34%). The managerial approaches and marketing activities of shopping centers aimed at customers, internal employees, and tenants of the shopping centers were assessed. In addition to profit, the main social aspect on which the management of shopping centers places an emphasis is also loyalty. A properly set working environment and working conditions are essential to achieve higher employee productivity and consequently higher profits. The shopping centers should increase their social roles to preserve the well-being of their employees and enhance customer satisfaction.

Pengaruh Stigma Masyarakat Terhadap Pembentukan Konsep Diri Remaja Penyalahgunaan Narkoba di Yayasan Bersama Kita Pulih (BESAKIH)

Tujuan penelitian ini adalah untuk melihat bagaimana stigma masyarakat mempengaruhi konsep diri remaja penyalahgunaan narkoba di Yayasan Bersama Kita Pulih. Penelitian ini menggunakan pendekatan kualitatif dan metode yang digunakan adalah studi kasus dengan responden sebanyak 2 orang remaja penyalahguna narkoba. Pengambilan sampel menggunakan wawancara, observasi dan dokumentasi. Hasil dari penelitian ini menunjukkan bahwa responden pertama yang berinisial AA sudah memiliki konsep diri yang positif setelah melakukan rehabilitasi. hal tersebut terlihat dari mulai terpenuhinya dimensi-dimensi dalam konsep diri yaitu dimensi pribadi, dimensi sosial, dimensi fisik, dimensi etika dan moral serta dimensi keluarga. Sedangkan responden kedua yang berinisial MAM memiliki konsep diri yang negatif ditandai tidak merasa dirinya bermasalah dan tidak memerlukan perawatan rehabilitasi. Hal tersebut karena MAM memiliki kontrol emosi yang rendah, penerimaan diri yang negatif dan rendahnya tingkat beradaptasi dengan lingkungan. Stigma masyarakat 50% cukup berpengaruh terhadap pembentukan konsep diri pada remaja jika hubungan dengan keluarga kurang baik. Karena pada masa remaja sangat diperlukan dukungan dan kasih sayang orangtua dalam perkembangan emosional remaja. The purpose of this research is to see how social stigma affects self-concept of adolescent drug abuse at Yayasan Bersama Kita Pulih. This research uses a qualitative approach and method that is used is a case study with the respondents of 2 adolescents who abuse drugs. Sampling uses interview, observation and documentation. The result of this research shows that the first respondent with the initials AA already has a positive self-concept after doing the rehabilitation. It can be seen from starting the fulfillment of dimensions in self-concept, namely personal dimension, social dimension, physical dimension, ethical and moral dimensions and also family dimension. While, the second respondent with the initials MAM has a negative self-concept that is indicated from not feeling that his self is problematic and does not require rehabilitation treatment. This is because MAM has a low emotional control, negative self-acceptance and a low level-adaptation with the environment. 50% of social stigma is quite influential towards the formation of self-concept in adolescent if the relationship with the family is not good enough. Because in adolescence, parental support and affection are required in adolescent emotional development.

Economic, Ecological and Social Analysis Based on DEA and MCDA for the Management of the Madrid Urban Public Transportation System

The aim of this research is to help public transport managers to make decisions on the type of buses that should compose their public transport fleet, taking into account economic, environmental and social criteria from the point of view of sustainability. This paper fills a knowledge gap by including the social dimension of sustainability in addition to the economic and environmental dimensions. The original nature of this study lies in analyzing complementarities in the structuring of an efficiency and multicriteria problem. Our research analyzes Madrid public bus system data; the problem is structured in a comparative way between two analytical methods, a Data Envelopment Analysis (DEA) and an ELimination Et Choice Translating REality (ELECTRE) III. Our research results show that two main groups of vehicles could play a part in part the theoretical solution. The main conclusions of this research are that (a) plug-in and induction electric vehicles are not comparable to GNC and diesel–hybrid vehicles in terms of cost, pollution and service; and (b) the ELECTRE III model provides more information in solving this problem than the DEA model.

University spaces for cooperation strengthening pro-innovative attitudes of academic community

The article and its undertaken matter are part of the discussion on the pro-innovative nature of a university – featuring examples of (mainly educational) activities which boost innovation on the university campus and beyond, and referring to trends occurring in the analysed areas. The presented content has been limited to the social dimension of innovation, which among other things, changes the way of perceiving the world and interpersonal relations, also in terms of organization of workspaces and (co)working methods. The purpose of the article is also to draw attention to the participation of students, academic teachers in various activities (also pro-innovative ones) taking place within a non-traditional social infrastructure. Problem analysis was based on literature studies, including reports on research on innovation as well as on the author’s professional experience related to new spaces of education – and an attempt to answer the question: “Can cooperation within the described spaces strengthen pro-innovative attitudes, including the attitudes of future pedagogues?”

Research Trends on Climate Change and Circular Economy from a Knowledge Mapping Perspective

The circular economy (CE) has been proposed as a potentially significant catalyst to enhance the current response to the global climate crisis. The objective of this study was to investigate the scientific literature of the research between climate change and CE adopting a knowledge mapping approach. Based on a total of 789 peer-reviewed publications extracted from Scopus, we found that research on climate change and CE is continually growing and interdisciplinary in nature. Europe notably leads scientific production. Keyword evolution shows that CE has been influenced by more lines of research than climate change. We also found that waste management is the CE approach most associated with climate change, mitigation is the climate action most impacted by CE, and food is the most reported greenhouse gas (GHG)-emitting material. However, there are knowledge gaps in the integration of the social dimension, the promotion of climate change adaptation, and the association of sustainable development goal (SDG) 13. Finally, we identified four potentially valuable directions for future studies: (i) CE practices, (ii) bioeconomy, (iii) climate and energy, and (iv) sustainability and natural resources, in which carbon recovery technologies, green materials, regional supply chains, circular agriculture models, and nature-based solutions are promising themes.

Analysis of Sustainability In Livestock Production Systems In Cordoba, Colombia.

The concept of sustainability is usually broad; it refers to the ability of the system to meet the current demand for livestock products without compromising the use of resources by future generations. Therefore, this study has been conducted to provide an overview of rotational, intensive, and regenerative livestock models to evaluate and measure their level of sustainability in the environmental, social, and economic dimensions to guide livestock guilds, professionals and stakeholders to transform their agricultural systems by adopting the concept of sustainability. The results show that the regenerative livestock system has a high association with the economic dimension in the Almost Good category, in the environmental dimension in the Moderate category, and in the social dimension in the Almost Good and Very Good categories. On the other hand, the rotational livestock system and the intensive livestock system have an association with the environmental dimension categorized as good; however, the association of the intensive livestock system is not as strong as that of the rotational livestock system.
