Development of sustainable manufacturing decision making models for small and medium enterprises / Sujit Singh
Get PDFSustainable manufacturing aims to manage the operations in an environmentally and
socially responsible manner. Several organizations have already incorporated the
concept of sustainable manufacturing. However, many Small and Medium Enterprises
(SMEs) that account for approximately 90% of all enterprises are not yet embraced this
opportunity. Therefore, it is important to develop the sustainable manufacturing
decision making models that suited to the characteristics of manufacturing SMEs. In
order to achieve that, this study aims to identify key sustainable manufacturing
performance measures & metrics and develop the sustainability evaluation and strategy
selection models.
This study includes an empirical study to identify the key performance measures for
sustainability assessment of manufacturing SMEs in an effective and comprehensive
manner using the Triple Bottom-Line framework. In order to investigate the importance
and applicability of the proposed measures and metrics, a survey was conducted among
the practitioners. The result of Mann-Whitney U-test confirms that there is no
significant difference between the importance and applicability of the proposed
measures. Considering the human reasoning based decision-making in manufacturing
SMEs,the development of decision-making models are based on the fuzzy set theory.
This study also develops two sustainability performance evaluation models and one
strategy selection model. For performance evaluation, the list of sustainability
performance measures and metrics that is identified during the empirical study is
applied. Consequently, a sensitivity analysis of the proposed method reveals the most
important basic indicators affecting overall sustainability, identifying areas which
decision makers should place special attention. For strategy selection model, the study
develops a hierarchal multi-criteria decision making (MCDM) method by combining
iv
Analytical Hierarchal Process (AHP) and VlseKriterijuska Optimizacija I
Komoromisno Resenje (VIKOR) methods under interval-valued fuzzy environment.
The linguistic variables were expressed in the triangular interval-valued fuzzy sets.
Using a case study of manufacturing SME, the final ranking of the strategies was
elicited in accordance with this procedure. Subsequently, a sensitivity analysis was
performed to validate the stability of the proposed final ranking. Apart from above
mentioned studies, this study also includes the development of a fuzzy rule based expert
system to provide an easy to access, time-saving and cost-effective way for
sustainability evaluation and strategy selection. The expert system has two components:
(1) sustainability evaluation and (2) strategy selection. The measures that are found
important during sustainability evaluation process are considered as selection criteria for
strategy selection. The applicability of the models and expert system were validated by
implementation in manufacturing SMEs.
This study contributes in several ways to the research field of sustainable
manufacturing decision making. It provides a list of key performance measures and
metrics for sustainability evaluation of manufacturing SMEs. In conjunction with the
sustainability evaluation models and strategy selection model, this study assists the
decision maker for improving their sustainability performances. An easy to access
expert system provides a time saving, cost effective way for sustainable manufacturing
decision making. The list of key performance measures & metrics, various modelling
approaches and an expert system should also enrich the literature
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Commentary : two sides of the same coin
Get PDFIssue 41 of Foresight featured a short commentary by Sujit Singh on the gaps between academia and business. Powered by our focus to produce and disseminate research that is directly applicable to practice, in this commentary we present our views on some of the very useful and interesting points raised by Sujit and conclude with our vision for enhanced communication between the two worlds
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
