Blockchain in operations management and manufacturing: Potential and barriers

In the realm of the current industrial revolution, interesting innovations as well as new techniques are constantly being introduced by offering fertile ground for further investigation and improvement in the industrial engineering domain. More specifically, cutting-edge digital technologies in the field of Extended Reality (XR) have become mainstream including Augmented Reality (AR). Furthermore, Cloud Computing has enabled the provision of high-quality services, especially in the controversial field of maintenance. However, since modern machines are becoming more complex, maintenance must be carried out from experienced and well-trained personnel, while overseas support is timely and financially costly. Although AR is a back-bone technology facilitating the development of robust maintenance support tools, they are limited to the provision of predefined scenarios, covering only a limited number of scenarios. This research work aims to address this emerging challenge with the design and development of a framework, for the support of remote maintenance and repair operation based on AR, by creating suitable communication channels between the shop-floor technicians and the expert engineers who are utilizing real-time feedback from the operator’s field of view. The applicability of the developed framework is tested in vitro in a lab-based machine shop and in a real-life industrial scenario.

Real-Time Remote Maintenance Support Based on Augmented Reality (AR)

Estas notas de aula ja tinham sido publicadas anteriormente, por meio da colecao SALA DE AULA, da Cooperativa Cultural – UFRN. A ideia inicial surgiu com a reformulacao do programa da disciplina “Elementos de Matematica e Estatistica”, que era oferecida para o curso de Psicologia. Na atual edicao, houve a inclusao de alguns topicos relacionados as variaveis aleatorias continuas e de algumas das suas principais distribuicoes, bem como a insercao de um capitulo sobre regressao linear simples. Alem desses acrescimos, foram corrigidos erros da edicao anterior.

Abstract Augmented and Mixed Reality (AR/MR) technologies enhance the human perception of the world by combining virtual and real environments. With the increase of mobile devices and the advent of 5G, this technology has the potential to become part of people’s life. This article aims to evaluate the impact of 5G and beyond mobile networks in the future of AR/MR. To attend to this objective, we surveyed four digital libraries to identify articles and reviews concerning AR/MR use based on mobile networks. The results describe the state-of-the-art of mobile AR/MR applications and the benefits and challenges of the technology. Finally, after the review, we propose a roadmap concerning AR/MR hardware and software development to run applications supported by future mobile networks.
