Digital transformation strengthens the interconnection of companies in order to develop optimized and better customized, cross-company business models. These models require secure, reliable, and traceable evidence and monitoring of contractually agreed information to gain trust between stakeholders. Blockchain technology using smart contracts allows the industry to establish trust and automate cross-company business processes without the risk of losing data control. A typical cross-company industry use case is equipment maintenance. Machine manufacturers and service providers offer maintenance for their machines and tools in order to achieve high availability at low costs. The aim of this chapter is to demonstrate how maintenance use cases are attempted by utilizing hyperledger fabric for building a chain of trust by hardened evidence logging of the maintenance process to achieve legal certainty. Contracts are digitized into smart contracts automating business that increase the security and mitigate the error-proneness of the business processes.
Gamification in Industrial Production: An Overview, Best Practices, and Design Recommendations
(2023)
This work describes gamification as a path to increase both productivity and motivation of persons working in industrial production. While gamification has been established in pedagogy or health more than two decades ago, its transgression to the industrial domain started around the year 2010. A discussion of production-specific requirements and the psychological background provide an overview on production-oriented gamified solutions in recent years. We look at how gamification designs evolved to minimize distraction while maximizing acceptance. Based on three best practices, we describe ways to neatly integrate gamification into workflows, use context-awareness to augment work and adapt the challenge-level to keep users in a state of flow. Furthermore, we investigate ways to further increase acceptance by creating user-specific “bottom-up” gamification designs, like custom agents and branded gamification. The overview concludes with design recommendations tailored for the production domain.
Innovative financing schemes in public management comprise provisions of funds for public expenditure by taxation, user charges, borrowing or other fundraising in a novel way. Scholarly research regarding public finance already appeared in the 16th century, but the role of public funding schemes became much more important in the last decades. Theoretical frameworks are related to political, economic, legal and administrative aspects. Although innovation and public management might be seen as antithetical, there is an emerging practice of innovative financing tools both in highly-industrialised economies and developing countries. Examples for novel mechanisms raising money are green bonds, onshore local currency financing, public private partnerships (PPPs) and resource-financed infrastructure. Public policy tools include innovation financing for digital infrastructure or export credits for trade-driven innovation, often focusing on the United Nations Sustainable Development Goals (SDGs) including climate action.
In this work, time-independent and time-dependent plasticity models are presented that are well suited for the calculation of stresses and strains with the finite-element method to assess the low-cycle and thermomechanical fatigue life of engineering components. The focus are plasticity models that are available in finite-element programs nowadays as standard material models and describe isotropic and kinematic hardening, strain-rate dependency as well as static recovery of hardening. For the presented models, aspects relevant for the application of the models are addressed as the determination of the material properties and the numerical implementation. Nevertheless, the plasticity models are also embedded in the thermodynamic framework used for the derivation of thermodynamically consistent plasticity models. Only uniaxial formulations are used to achieve a good readability and preventing the use of tensors.
Achieving Positive Hospitality Experiences through Technology: Findings from Singapore and Malaysia
(2021)
Customers’ experience is one of the most impactful factors in the tourism industry. Only by offering customers an excellent experience is it possible to build and ensure long-term customer loyalty. In today’s world, technology plays a key role in providing customers with an excellent customer experience. This study has the objective of analyzing how a positive customer experience can be achieved, and which technologies are necessary to ensure this. Results were collected through a literature review, and qualitative interviews with managers of selected hotels, as well as of attractions in Malaysia and Singapore. The analysis of these hotels and attractions is based on a set of criteria to determine the extent of the adoption of the new standards that contribute to positive online customer experiences. As a conclusion, different perspectives are compared, and positive and negative aspects of the use of modern technologies in the tourism industry are specified and discussed.
Recent advances in motion recognition allow the development of Context-Aware Assistive Systems (CAAS) for industrial workplaces that go far beyond the state of the art: they can capture a user's movement in real-time and provide adequate feedback. Thus, CAAS can address important questions, like Which part is assembled next? Where do I fasten it? Did an error occur? Did I process the part in time? These new CAAS can also make use of projectors to display the feedback within the corresponding area on the workspace (in-situ). Furthermore, the real-time analysis of work processes allows the implementation of motivating elements (gamification) into the repetitive work routines that are common in manual production. In this chapter, the authors first describe the relevant backgrounds from industry, computer science, and psychology. They then briefly introduce a precedent implementation of CAAS and its inherent problems. The authors then provide a generic model of CAAS and finally present a revised and improved implementation.
DE\GLOBALIZE
(2020)
It is the purpose of this paper to address ethical issues concerning the development and application of Assistive Technology at Workplaces (ATW). We shall give a concrete technical concept how such technology might be constructed and propose eight technical functions it should adopt in order to serve its purpose. Then, we discuss the normative questions why one should use ATW, and by what means. We argue that ATW is good to the extent that it ensures social inclusion and consider four normative domains in which its worth might consists in. In addition, we insist that ATW must satisfy two requirements of good workplaces, which we specify as (a) an exploitation restraint and (b) a duty of care.
Power systems are increasingly built from distributed generation units and smart consumers that are able to react to grid conditions. Managing this large number of decentralized electricity sources and flexible loads represent a very huge optimization problem. Both from the regulatory and the computational perspective, no one central coordinator can optimize this overall system. Decentralized control mechanisms can, however, distribute the optimization task through price signals or market-based mechanisms. This chapter presents the concepts that enable a decentralized control of demand and supply while enhancing overall efficiency of the electricity system. It highlights both technological and business challenges that result from the realization of these concepts, and presents the state-of-the-art in the respective domains.
