Braithwaite Company Ltd. (Braithwaite) was a specialized engineering firm headquartered in Kolkatta, India. It primarily undertook structural steel fabrication to make railway wagons and bridge structures. It was incorporated as a private enterprise almost a century back. However, since its nationalization five decades ago, it has been operating as a public sector undertaking (PSU) under the aegis of Indian Railways, a department of the Government of India. The case documents the past three decades of the firm’s journey, during which it experienced three episodic turnarounds. Details of the first two turnarounds are presented as the background, in light of which sustainability of the third turnaround is to be examined. The case explores the sustainability of organizational turnarounds from the perspective of the current Chairman and Managing Director (CMD), the case protagonist. Braithwaite underwent financial and operational distress in 1992, 2005 and 2015 and negotiated them under different leaders. These leaders from diverse backgrounds used distinct tactics and strategies to bring about organizational turnarounds. The case provides data and information to assess the sustainability of the third turnaround. Hence, it allows a class to explore the paradoxical observation that while “turnaround” inherently implies sustenance of good performance over time, turnaround sustainability is not spontaneous in the real world. The case deals with the performance issues of PSUs, which make significant contributions to the national economy in the case of emerging economies (for example, 5%–8% of the Indian National gross domestic product is contributed by PSUs; https://swarajyamag.com/ideas/psus-are-crucial-for-indias-growth-but-only-if-they-play-a-strategic-role). Under government ownership and management, the poor performance of PSUs is often attributed to bad decision-making by its top management. In contrast, Braithwaite’s top management’s sound contextual decision-making resulted in a jump in its performance during each turnaround phase, but unsound fundamentals resulted in the unsustainability of the turnarounds. Hence, the case enables an exploration of the unique challenges faced by PSU that emanate from legacy roles, monopolistic markets and dual purpose – the concurrent pursuit of profits and social welfare. Consequently, the case allows an examination of the reasons for the distress of PSUs and the viability of turnaround strategies in the context of the broader Business–Government–Society landscape in emerging economies.

The case is written for use in the MBA elective course covering “Strategic Revival and Turnaround Strategies.” It can be used at the beginning of the course to identify reasons for organizational failure/distress or in the later part of the course to discuss the implementation of operational and strategic turnaround strategies.

To recognize and investigate the hypotheses that opportunistic behaviour of project participants in infrastructure public–private partnerships (PPPs) changes over the project’s life cycle. Case study methodology is adopted. The first Indian highway PPP project, awarded with negative grant, is used as the case context. Opportunistic behaviour is a continuous game played by the project stakeholders. Its manifestation depends on the vulnerability of the other party at that point in time in the project life cycle and the past display of opportunism. Because the study is limited to a highway project in an emerging economy, the findings may lack generalizability for which further research is recommended. PPP is increasingly popular. Stakeholders recognize that the existing ex-ante contractual arrangements that seek to mitigate opportunism are not enough for project success. This study addresses this difficulty by providing a closer understanding of how opportunistic behaviours evolve over projects’ life cycle and what steps are necessary to negotiate. Failure to address the antecedents of opportunistic behaviour in time leads to a competition to be more opportunistic, in which the common public gets short changed. This study is an attempt to advance understanding of stakeholders’ behaviour outside the ambit of contract. The extant literature is largely silent on the timing and vulnerability of opportunistic behaviour, viewing it as a static concept. The study demonstrates the changing nature of opportunism that manifests in different forms over the projects life cycle.

Fused deposition modelling (FDM) is the most economical additive manufacturing technique. The purpose of this paper is to describe a detailed review of this technique. Total 211 research papers published during the past 26 years, that is, from the year 1994 to 2019 are critically reviewed. Based on the literature review, research gaps are identified and the scope for future work is discussed.

Literature review in the domain of FDM is categorized into five sections – (i) process parameter optimization, (ii) environmental factors affecting the quality of printed parts, (iii) post-production finishing techniques to improve quality of parts, (iv) numerical simulation of process and (iv) recent advances in FDM. Summary of major research work in FDM is presented in tabular form.

Based on literature review, research gaps are identified and scope of future work in FDM along with roadmap is discussed.

In the present paper, literature related to chemical, electric and magnetic properties of FDM parts made up of various filament feedstock materials is not reviewed.

This is a comprehensive literature review in the domain of FDM focused on identifying the direction for future work to enhance the acceptability of FDM printed parts in industries.

This paper aims to examine the current status and trends in circular economy (CE) research. The state of CE research is assessed by critically examining the field by considering diverse dimensions.

The systematic literature review (SLR) of CE research articles is analyzed using the content analysis methodology. The articles are selected from the Scopus database containing the keyword “Circular economy” in its title, abstract and keywords. In total, 587 research articles published on CE in various reputed peer-reviewed journals over 15 years (2005–2020) are selected for review.

The research in the domain of CE is in the beginning phase. It has numerous quantitative modeling opportunities, value creation and propositions aspects and application in real-life case problems. One of the significant findings is that the CE research field is more inclined toward the implication of the empirical qualitative research. The identified research gaps and future opportunities could provide further direction to broaden CE research.

The review focuses on publications published in peer-reviewed journals in the English language only. It restricts the recognition of relevant articles published in conference proceedings and languages other than English.

This research study will provide a deeper understanding of CE research's existing status and highlights the research trends, gap and its applicability in real-life case problems and setting up future research directions in the CE field.

This research aims to explore the various green supply chain management (GSCM) performance measures and develop the efficient performance measurement framework for evaluation of influence of GSCM adoption on organizational performance.

This research proposes a hybrid framework of Pythagorean fuzzy analytic hierarchy process and Pythagorean fuzzy weighted aggregated sum product assessment technique. The usefulness of proposed framework is validated using empirical case example of Indian manufacturing organization.

The finding reveals that the overall performance of case organization is 67.03% based on define set of performance measures. Further, the proposed framework has been validated with other three Indian automobile manufacturing organizations. The results obtained were confirmed with selected empirical case company. The proposed hybrid framework provides the effective path to measure and benchmark the impact of each performance measures on system performance.

This research is limited to automobile sector of India; hence the results obtained in this study may not be comprehensibly used to other sectors due to different product and process fields.

This research aids the industrial practitioners to effectively implement the green supply chain management (GSCM) and helps them to boost the overall performance of business organizations in three dimensions of sustainability.

This research aims to identify and prioritize the circular economy (CE) benefits (CEBs) due to the adoption of CE enablers (CEEs) in the Indian manufacturing organization context.

This research proposes a hybrid framework of Pythagorean fuzzy analytic hierarchy process (PF-AHP) and Pythagorean fuzzy TODIM (an acronym in Portuguese for Interactive Multicriteria Decision-Making) techniques. It identifies the CEEs and CEBs based on literature review and validated through industrial experts. Further, this research conducts an empirical case study to demonstrate the applicability of the proposed framework.

The result shows that CE enabler SE1 (clear vision, support and commitment from top management for CE adoption) is the most critical enabler for CE implementation. The CE benefit CEB1 (improves the value chain of products and mitigating environmental damage during product life cycle phase) is the most significant benefit derived from the adoption of CEEs. The proposed framework will provide a more accurate, structural and systematic approach to the business organizations for achieving the CEBs in a stepwise manner through the effective adoption of CEEs.

The findings of this research are nation-specific and based on a case study of single manufacturing industry. Thus, the result obtained can vary from case to case and nation to nation.

A deep understanding of each CEEs and CEBs would help build confidence among decision-makers and industrial practitioners to eliminate the risks associated with CE implementation.

Auxetic structures are one type of mechanical meta-materials mainly used for energy absorption applications because of their unique negative Poisson’s ratio. This study is focused on numerical and experimental investigations of fused deposition modeling (FDM) fabricated re-entrant auxetic structures of acrylonitrile butadiene styrene (ABS) and poly-lactic acid (PLA) materials under compressive loading. Influence of geometric parameters, namely, re-entrant angle, height and arm-length on strength, stiffness and specific energy absorption (SEA) of auxetic structures under compressive loading. Optimization of significant parameters is also performed to maximize these responses and minimize weight and time of fabrication. Further, efforts have also been made to develop predictive models for strength, stiffness and SEA of auxetic structures.

A full factorial design of experiment is used for planning experiments. Auxetic structures of ABS and PLA are fabricated by FDM technique of additive manufacturing within the constrained range of geometric parameters. Analysis of variance is performed to identify the influence of geometric parameters on responses. To optimize the geometric parameters Gray relational analysis is used. Deformation of auxetic structures is studied under compressive loading. A numerical investigation is also performed by building nonlinear finite element models of auxetic structures.

From the analysis of results, it is found that re-entrant angle, height and arm-length with their interactions are significant parameters influencing responses, namely, strength, stiffness and SEA of the auxetic structures of ABS and PLA materials. Based on the analysis, statistical nonlinear quadratic models are developed to predict these responses. Optimal configurations of auxetic structure of ABS and PLA are determined to maximize strength, stiffness, SEA and minimize weight and time of fabrication. From the study of deformation of auxetic structures, it is found that ABS structures have higher energy absorption, whereas PLA structures have better stiffness. Results of finite element analysis (FEA) are found in good agreement with experimental results.

The present study is limited to re-entrant type of auxetic structures of ABS and PLA materials only under compressive loading. Also, results from the present study are valid within the selected range of geometric parameters. The findings of the present study are useful in maximizing strength, stiffness and SEA of auxetic structures that have wide applications in the automotive, aerospace, sports and marine sector.

No literature is available on studying the influence of geometric parameters, namely, re-entrant angle, height and arm-length of auxetic structure on strength, stiffness and SEA under compressive loading. Also, a comparative study of feedstock materials, namely, ABS and PLA, is also not reported. The present work attempts to fulfill the above research gaps.
