Control of Cyber-Physical Production Systems: A Concept to Increase the Trustworthiness within Multi-Agent Systems with Distributed Ledger Technology

In the course of increasing the flexibility in the area of production, industrial enterprises have been presented with cyber-physical production systems (CPPS). Through the use of autonomously acting CPPS and CPPS components – which often receive multi-agent systems as their corresponding cyber parts – new challenges arise from the need for flexibility and interoperability on the one hand and consistency, trustworthiness as well as reliability of the systems and their components on the other. In order to meet these challenges, this research paper is dedicated to the creation of a technical concept for implementing distributed ledger technology production systems. The paper follows a design-science approach, which consist of analysis, design, and evaluation. The technical concept is based on the GAIA method, which aims to design multi-agent systems and specifically addresses the security and trustworthiness of CPPS-environments. The subsequent evaluation of the concept based on discussions with experts documents its relevance and potential

Toward a conceptual framework for designing sustainable cyber-physical system architectures: A systematic mapping study

Cyber-physical systems (CPS) represent devices whose components enable interaction between machines and processes. One of the biggest challenges of these systems today is the ability to adjust to changes at the time of execution as they are implemented in environments with a multidimensional complexity, this challenge is currently addressed from the design of the systems themselves by integrating sustainability. With this problem in mind, the present document describes a systematic mapping study of the literature with the goal of demonstrating the current panorama of the frameworks, designs, and/or models used at the time of initiating the development of a cyber-physical system. As a result, it has been concluded that there is a lack of guidelines to construct sustainable, and evolvable cyber-physical systems. To address these issues, a framework for designing sustainable CPS architectures is outlined

Sistematização dos requisitos gerais para o desenvolvimento de software na indústria 4.0

The identification and implementation of technologies and innovations, through the development of business strategies, are factors that contribute to organizational success. In this context, industry 4.0 can contribute to the development of industries that seek technological and innovative differentials. The objective of this research is to develop a system for software development in industry 4.0. Because they are current topics and linked to technology and innovation, they are still underdeveloped in academic studies. Through a bibliographic review, using bibliometrics and content analysis techniques, the general requirements for software development in industry 4.0 were identified, and for each requirement, what are the challenges, risks, gaps, advantages and trends. The systematic is analyzed by academic experts, being considered as theoretical with the incorporations of the practice. The AHP method was used to prioritize the requirements, resulting in the adjusted systematic, having as elements and relative score of the specialists: analysis of opportunities 34.98%, operational efficiency 2.0 19.41%, optimization of the business model 15.57%, information technology 20.26%, IT integration 12.29%, IT security management 7.97%, new interfaces and data 17.93%, data analysis and management 6.90%, new intellectual property management 6.69%, cloud-based applications 4.34%, integrated and intelligent management 10.75%, intelligent supply chain 3.85%, lifecycle management 3.81%, intelligent logistics 3.09%, change and learning 16.08%, corporate business 9.33%, organizational learning 6.75%. Among the criteria, the requirement that got the most weight was the analysis of opportunities and among the sub-criteria the ones with the highest weight were: operational efficiency, optimization of the business model and IT integration. Finally, an analysis by specialists from companies that develop software is applied to understand how the requirements are used in these companies, reaching the final system. The research through the AHP, showed the importance of analyzing opportunities and operational efficiency in organizations, justifying that companies are concerned with identifying business opportunities and managing processes efficiently. These results also showed the stage of preparing the system as the most relevant. The interviews demonstrated the concern with cybersecurity and IT integration tools, but the gap was shown in relation to the development of integrated and intelligent management, with emphasis on intelligent logistics.Agência 1A identificação e implementação das tecnologias e inovações, por meio do desenvolvimento de estratégias empresariais, são fatores que contribuem para o sucesso organizacional. Neste contexto, a indústria 4.0 pode contribuir para o desenvolvimento das indústrias que buscam pelo diferencial tecnológico e inovador. O objetivo desta pesquisa é desenvolver uma sistemática para o desenvolvimento de software na indústria 4.0. Por serem temas atuais e ligados à tecnologia e inovação, ainda são pouco desenvolvidos nos estudos acadêmicos. Por meio de uma revisão bibliográfica, utilizando técnicas de bibliometria e análise de conteúdo, identificaram-se os requisitos gerais do desenvolvimento de software na indústria 4.0, e para cada requisito, quais são os desafios, riscos, lacunas, vantagens e tendências. A sistemática passa por análises de especialistas acadêmicos, sendo considerada como teórica com as incorporações da prática. O método AHP foi utilizado para priorizar os requisitos, resultando na sistemática ajustada, tendo como elementos e pontuação relativa dos especialistas: análise de oportunidades 34,98%, eficiência operacional 2.0 19,41%, otimização do modelo de negócios 15,57%, tecnologia da informação 20,26%, integração de TI 12,29%, gerenciamento de segurança de TI 7,97%, novas interfaces e dados 17,93%, análise e gerenciamento de dados 6,90%, novo gerenciamento de propriedade intelectual 6,69%, aplicações baseadas em nuvem 4,34%, gestão integrada e inteligente 10,75%, cadeia de suprimentos inteligente 3,85%, gerenciamento do ciclo de vida 3,81%, logística inteligente 3,09%, mudança e aprendizagem 16,08%, negócio corporativo 9,33%, aprendizagem organizacional 6,75%. Entre os critérios, o requisito que obtive maior peso foi a análise de oportunidades e entre os subcritérios os de maior peso foram: eficiência operacional, otimização do modelo de negócios e integração de TI. Por fim, é aplicada uma análise de especialistas de empresas que desenvolvem software para entender como os requisitos são utilizados nessas empresas, chegando à sistemática final. A pesquisa por meio do AHP, mostrou a importância da análise de oportunidades e da eficiência operacional nas organizações, justificando que as empresas se preocupam em identificar as oportunidades de negócios e gerenciar os processos de forma eficiente. Esses resultados também mostraram a etapa de preparação da sistemática como a mais relevante. As entrevistas demonstraram a preocupação com a cybersegurança e as ferramentas de integração de TI, porém mostrou-se o gap em relação ao desenvolvimento da gestão integrada e inteligente, com destaque para a logística inteligente
