Digital ecosystems in manufacturing: emerging models for Industry 4.0
The impact of emerging technologies on manufacturing has been widely discussed in academic and practical circles, and yet it is still difficult to discern anectodical examples from the general trends characterizing the "Industry 4.0" revolution. This chapter draws from the results of an international expert study to identify agreed-upon evolutionary trajectories and ongoing question marks in the current understanding of the phenomenon. Around these ongoing uncertainties, the analysis of a series of illustrative case studies presents a reasoned repertoire of possible variations around the key issues of mass customization and manufacturing servitization
Industry 4.0 and Policies: A Classification
This paper proposes a classification framework of national Industry 4.0 policies based on previous contributions applied to different contexts. The sample selected for the study consists of the world's top 12 manufacturing countries and includes both developing and developed countries. (Brazil, China, France, Germany, India, Italy, Japan, Mexico, the Russian Federation, South Korea, the United Kingdom and the United States). The analysis reveals some differences (e.g. in terms of technologies, sectors and instruments) and similarities (e.g. in terms of economic objectives). The study provides policy makers with a framework of industrial 4.0 policies within which to identify and adapt the most appropriate interventions and actions
The “dark side” of Industry 4.0: How can technology be made more sustainable?
Purpose: A positive outlook on the impact of Industry 4.0 (I4.0) on sustainability prevails in the literature. However, some studies have highlighted potential areas of concern that have not yet been systematically addressed. The goal of this study is to challenge the assumption of a sustainable Fourth Industrial Revolution by (1) identifying the possible unintended negative impacts of I4.0 technologies on sustainability; (2) highlighting the underlying motivations and potential actions to mitigate such impacts; and (3) developing and evaluating alternative assumptions on the impacts of I4.0 technologies on sustainability. Design/methodology/approach: Building on a problematization approach, a systematic literature review was conducted to develop potential alternative assumptions about the negative impacts of I4.0 on sustainability. Then, a Delphi study was carried out with 43 experts from academia and practice to evaluate the alternative assumptions. Two rounds of data collection were performed until reaching the convergence or stability of the responses. Findings: The results highlight various unintended negative effects on environmental and social aspects that challenge the literature. The reasons behind the high/low probability of occurrence, the severity of each impact in the next five years and corrective actions are also identified. Unintended negative environmental effects are less controversial than social effects and are therefore more likely to generate widely accepted theoretical propositions. Finally, the alternative hypothesis ground is partially accepted by the panel, indicating that the problematization process has effectively opened up new perspectives for analysis. Originality/value: This study is one of the few to systematically problematize the assumptions of the I4.0 and sustainability literature, generating research propositions that reveal several avenues for future research
The future of manufacturing: A Delphi-based scenario analysis on Industry 4.0
Industry 4.0 is expected to impart profound changes to the configuration of manufacturing companies with regards to what their value proposition will be and how their production network, supplier base and customer interfaces will develop. The literature on the topic is still fragmented; the features of the emerging paradigm appear to be a contested territory among different academic disciplines. This study assumes a value chain perspective to analyze the evolutionary trajectories of manufacturing companies. We developed a Delphi-based scenario analysis involving 76 experts from academia and practice. The results highlight the most common expectations as well as controversial issues in terms of emerging business models, size, barriers to entry, vertical integration, rent distribution, and geographical location of activities. Eight scenarios provide a concise outlook on the range of possible futures. These scenarios are based on four main drivers which stem from the experts’ comments: demand characteristics, transparency of data among value chain participants, maturity of additive manufacturing and advanced robotics, and penetration of smart products. Researchers can derive from our study a series of hypotheses and opportunities for future research on Industry 4.0. Managers and policymakers can leverage the scenarios in long-term strategic planning
Blockchain in supply chain management: a multiple case study analysis on setups, contingent factors, and evolutionary patterns
Despite the hype about blockchains among supply chain management (SCM) practitioners and researchers, the technology’s adoption is still low, and confusion remains about its potential benefits for operational efficiency and effectiveness. Building on a multiple case study research, this paper clarifies current value creation opportunities enabled by the blockchain for product/material tracking and tracing. We highlight that the setup of blockchain projects depends on the presence of different drivers on customer value or efficiency and the focus towards products/components or raw materials. Based on how tracking and tracing drivers and focus influence the initial blockchain setup, contingent factors are discussed and possible evolutionary patterns are identified. These findings are elaborated in one setup matrix and three propositions. The study is one of the few to add empirical evidence to the mainly conceptual SCM blockchain literature and provides a middle-range theoretical contribution based on contingency theory. Furthermore, it offers actionable guidance for managers and policy makers about SCM blockchain adoption.</p
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
