Processing of materials by ultrashort laser pulses has evolved significantly over the last decade and is starting to reveal its scientific, technological and industrial potential. In ultrafast laser manufacturing, optical energy of tightly focused femtosecond or picosecond laser pulses can be delivered to precisely defined positions in the bulk of materials via two-/multi-photon excitation on a timescale much faster than thermal energy exchange between photoexcited electrons and lattice ions. Control of photo-ionization and thermal processes with the highest precision, inducing local photomodification in sub-100-nm-sized regions has been achieved. State-of-the-art ultrashort laser processing techniques exploit high 0.1–1 μm spatial resolution and almost unrestricted three-dimensional structuring capability. Adjustable pulse duration, spatiotemporal chirp, phase front tilt and polarization allow control of photomodification via uniquely wide parameter space. Mature opto-electrical/mechanical technologies have enabled laser processing speeds approaching meters-per-second, leading to a fast lab-to-fab transfer. The key aspects and latest achievements are reviewed with an emphasis on the fundamental relation between spatial resolution and total fabrication throughput. Emerging biomedical applications implementing micrometer feature precision over centimeter-scale scaffolds and photonic wire bonding in telecommunications are highlighted. The ability of femtosecond lasers to efficiently fabricate complex structures and devices for a wide variety of applications is reviewed. Mangirdas Malinauskas at Vilnius University in Lithuania and co-workers in Japan, Australia and Saudi Arabia describe how state-of-the-art laser processing techniques with ultrashort light pulses can be used to structure materials with a sub-micrometre resolution. Direct laser writing of suitable photoresists and other transparent media can create intricate three-dimensional photonic crystals, micro-optical components, gratings, tissue scaffolds and optical waveguides. Such structures are potentially useful for empowering next-generation applications in telecommunications and bioengineering that rely on the creation of increasingly sophisticated miniature parts. The precision, fabrication speed and versatility of ultrafast laser processing make it well placed to become a vital industrial tool for manufacturing.

Abstract Lean Production is widely recognized and accepted in the industrial setting. It concerns the strict integration of humans in the manufacturing process, a continuous improvement and focus on value-adding activities by avoiding waste. However, a new paradigm called Industry 4.0 or the fourth industrial revolution has recently emerged in the manufacturing sector. It allows creating a smart network of machines, products, components, properties, individuals and ICT systems in the entire value chain to have an intelligent factory. So, now a question arises if, and how these two approaches can coexist and support each other.

Abstract The fourth industrial revolution (Industry 4.0) is changing not only the manufacturing industry but also the construction industry and its connected supply chains. Construction supply chains (CSCs) have specific characteristics, such as being temporary organizations that require high coordination efforts to align the processes of supply chain actors. The concept of proximity is used to analyze synchronization between suppliers and the construction site. This article presents a framework for explaining Industry 4.0 concepts that increase or reduce proximity. We find that Industry 4.0 technologies mainly influence technological, organizational, geographical and cognitive proximity dimensions. This presents benefits and challenges for CSCs. This framework is based on the results of a systematic literature review of scientific papers and analysis of applicability through practical publications and examples from industrial case studies.

Abstract Blockchain is becoming a widespread digital technology that allows every transaction to be tracked in an inviolable way, hence making it possible to go back through the entire history of products and product components. Its idiosyncratic characteristics can be especially useful in the aircraft industry, a highly technologically-based sector, wherein manufacturers of components are governed by stringent technical standards, the aim of which is to certify and monitor the whole component production process. In addition, the sector makes significant use of additive manufacturing technologies to perform the rapid prototyping of product components, realized through the supply chain, hence reducing time-to-market, while ensuring quality and containing costs. Starting from these premises, the paper focuses on the phases characterizing the metal additive manufacturing process, in which a component for the aircraft industry can be produced and proposes a digital twin for additive manufacturing in the aircraft industry through the exploitation of Blockchain solutions. In doing so, the paper provides a conceptual answer to securing and organizing the data generated through an end-to-end additive manufacturing process in the aircraft industry and underlines how companies exploiting Blockchain can build secure and connected manufacturing infrastructure.

Abstract The fourth industrial revolution and its Industry 4.0 or connected industry technologies dominates the current discussion of production research. Digital developments like cyber-physical Systems are the key technologies for future, more agile production systems but a common understanding of the term Industry 4.0 is not established in this time. First generic implementation approaches present manifold technical solutions but miss an integrated consideration with existing Lean Production Systems. The actual impact of Industry 4.0 solutions is mostly not clearly specified and a method to evaluate is missing. This paper introduces the Industry 4.0 in an environment of connectability in the Internet of Things and Services with the vision of a smart factory. The initial situation of industrial companies is characterized by Lean Production Systems and Lean Principles. For companies, Industry 4.0 offers an estimated benefit by stabilizing Lean processes with Industry 4.0 applications. To support the development process the presented Concept of an Industry 4.0 impact matrix on lean production systems gives a useable framework. The matrix considers elements of lean production systems with Industry 4.0 technologies and gives a first estimation of impact. In the described development process of a cyber-physical Just-in-Time delivery the matrix is used to find a stabilizing application for a Just-in-Time material supply process.

Abstract Researchers and practitioners are giving significant attention to Industry 4.0 due to its numerous benefits to manufacturing organizations. Several aspects of Industry 4.0 have been studied in the literature. However, studies on the challenges for implementing Industry 4.0 in manufacturing operations have received less attention. To address this gap, this study identifies a set of challenges (framework) for implementing Industry 4.0 in manufacturing industries. This framework is evaluated in the leather industry of Bangladesh aided by a novel multi-criteria decision-making method named Best-Worst method (BWM). The findings of the study showed that ‘lack of technological infrastructure’ is the most pressing challenge that may hurdle the implementation of Industry 4.0 whereas ‘environmental side-effects’ is the less among the challenges that may hinder implementation of Industry 4.0 in the Bangladeshi leather industry. This result may help decision makers, industrial managers and practitioners in the Bangladeshi leather industry to realize the actual challenges confronting them when attempting to implement Industry 4.0 and focus their attention on how to address these challenges to pave ways for a successful implementation of Industry 4.0.

We are witnessing an increasing adoption of digital technologies in manufacturing industries around the globe. This trend is often debated under the label Industry 4.0. A key claim put forward in these debates is that Industry 4.0 represents a revolution that will reshape manufacturing industries akin to previous industrial revolutions. Despite the popularity of this claim, it provides little help to clarify the identity of Industry 4.0. Such a clarification is however much needed given the worldwide proliferation of digital technologies in manufacturing industries. I address this gap by arguing to view Industry 4.0 as policy-driven innovation discourse in manufacturing industries that aims to institutionalize innovation systems that encompass business, academia, and politics. This clarification of the identity of Industry 4.0 adds to a better understanding of the relationship between manufacturing and politics as well as technological change in manufacturing.

Abstract The cybersecurity issues represent a complex challenge for all companies committing to Industry 4.0 paradigm. On the other hand, the characterization of cybersecurity concept within Industry 4.0 contexts proved to be an emerging and relevant topic in the recent literature. The paper proposes to analyse, through a systematic literature review approach, the way in which the existing state of art deals with the cybersecurity issues in Industry 4.0 contexts. In particular, the focus will be on the investigation of the main elements associated with cybersecurity theme (i.e. asset involved into cyber-attacks, system vulnerabilities, cyber threats, risks and countermeasures) within those industrial contexts where physical systems (machines, shop floors, plants) are connected each other via the Internet. Four areas of analysis are defined: definitions of cybersecurity and Industry 4.0 concepts, the industrial focus of the analysed studies, the cybersecurity characterization and the management attempts of cybersecurity issues. Through the literature review analysis, a framework of the main features characterizing each area is discussed, providing interesting evidences for future research and applications.

Purpose Industry 4.0 is assumed to yield extensive industry-spanning opportunities. However, exploiting these opportunities requires a targeted implementation of Industry 4.0. The purpose of this paper is to generate a deeper understanding of relevant implementation action. Existing recommendations are mostly general, highly aggregated and difficult to grasp. Yet, specific and concrete actions that need to be taken to accelerate the realization of Industry 4.0 are essential. Design/methodology/approach The article uses 13 semi-structured in-depth expert interviews as the source of empirical data. The interviews were conducted with managers from Industry 4.0-experienced German manufacturing companies. All interviews are analyzed using qualitative content analysis. Findings The study reveals relevant and targeted aspects for Industry 4.0 implementation: the development of Industry 4.0-specific know-how, securing financial resources, integrating employees into the implementation process and establishing an open-minded and flexible corporate culture. Further aspects include comprehensive planning processes, cooperation with external partners, proper handling of data interfaces, interdisciplinary communication, an adaptable organizational structure and data security. Research limitations/implications The paper is limited to German manufacturing enterprises and should be transferred to other industries and countries. Practical implications The study supports managers to effectively implement Industry 4.0 within their organizations and consequently benefit from Industry 4.0 and derives recommendations for future research. Originality/value The paper is among the first to give specific and concrete examples for lessons learned from Industry 4.0 implementation, directly obtained from industrial application.

The term culture industry was perhaps used for the first time in the book Dialectic of Enlightenment, which Horkheimer and I published in Amsterdam in 1947. In our drafts we spoke of "mass culture." We replaced that expression with "culture industry" in order to exclude from the outset the interpretation agreeable to its advocates: that it is a matter of something like a culture that arises spontaneously from the masses themselves, the contemporary form of popular art. From the latter the culture industry must be distinguished in the extreme. The culture industry fuses the old and familiar into a new quality. In all its branches, products which are tailored for consumption by masses, and which to a great extent determine the nature of that consumption, are manufactured more or less according to plan. The individual branches are similar in structure or at least fit into each other, ordering themselves into a system almost without a gap. This is made possible by contemporary technical capabilities as well as by economic and administrative concentration. The culture industry intentionally integrates its consumers from above. To the detriment of both it forces together the spheres of high and low art, separated for thousands of years. The seriousness of high art is destroyed in speculation about its efficacy; the seriousness of the lower perishes with the civilizational constraints imposed on the rebellious resistance inherent within it as long as social control was not yet total. Thus, although the culture industry undeniably speculates on the conscious and unconscious state of the millions towards which it is directed, the masses are not primary, but secondary, they are an object of calculation; an appendage of the machinery. The customer is not king, as the culture industry would like to have us believe, not its subject but its object. The very word mass-media, specially honed for the culture industry, already shifts the accent onto harmless terrain. Neither is it a question of primary concern for the masses, nor of the techniques of communication as such, but of the spirit which sufflates them, their master's voice. The culture industry misuses its concern for the masses in order to duplicate, reinforce and strengthen their mentality, which it presumes is given and unchangeable. How this mentality might be changed is excluded throughout. The masses are not the measure but the ideology of the culture industry, even though the culture industry itself could scarcely exist without adapting to the masses.

Abstract Ports and terminals have evolved and from the 2010s have entered into a fifth stage of evolution characterized by their digital transformation and alignment with Industry 4.0 practices. Co-operation among agents is a key element and integration not only involves Port Authorities, Terminals and Port users and related Port Services Providers but the city, port's hinterland and well beyond the Global Supply Chain. Internet of Things and sensing solutions, cybersecurity, horizontal and vertical system integration, cloud computing, 3D printing and additive manufacturing, big data and business analytics, augmented reality and simulation and modeling are the pillars of Industry 4.0. Some of those are mature enough in the port and maritime industry. However, others remain in their earliest stages in this business and thus, poorly covered by the scientific literature. The article reviews the state of the art on these new emerging technologies, summarizing how ports and terminals are deploying specific projects in the new era of smart ports and Ports 4.0.

Artificial intelligence (AI) in healthcare has led to many promising developments; however, increasingly, AI research is funded by the private sector leading to potential trade-offs between benefits to patients and benefits to industry. Health AI practitioners should prioritize successful adaptation into clinical practice in order to provide meaningful benefits to patients, but translation usually requires collaboration with industry. We discuss three features of AI studies that hamper the integration of AI into clinical practice from the perspective of researchers and clinicians. These include lack of clinically relevant metrics, lack of clinical trials and longitudinal studies to validate results, and lack of patient and physician involvement in the development process. For partnerships between industry and health research to be sustainable, a balance must be established between patient and industry benefit. We propose three approaches for addressing this gap: improved transparency and explainability of AI models, fostering relationships with industry partners that have a reputation for centering patient benefit in their practices, and prioritization of overall healthcare benefits. With these priorities, we can sooner realize meaningful AI technologies used by clinicians where mutua
