- A 70-Year industrial electronics society evolution through industrial revolutions: the rise and flourishing of information and communication technologiesPublication . Colombo, Armando W.; Karnouskos, Stamatis; Yu, Xinghuo; Kaynak, Okyay; Luo, Ren C.; Shi, Yang; Leitão, Paulo; Ribeiro, Luis; Haase, JanThe Industrial Revolution, which originally involved the change from an agrarian and handicraft economy to a market dominated by factory mechanization during the early 18th century, has profoundly shaped the world. It has progressed through four disruptive phases: Industry 1.0 through Industry 4.0. Industry 1.0 encompassed early automation, while Industry 2.0 began at the end of the 19th century, when enormous technological advances were made, such as mass production, electrification, and new modes of transportation. Industry 3.0 began during the 1970s, a decade that gave rise to the electronics, telecommunications, and computing that enable full automation and robotics. Industry 4.0 kicked off at the dawn of the third millennium, marked by the ubiquitous use of Internet technologies, which have radically transformed how people, society, and industry interact. The inception of the IEEE Industrial Electronics Society (IES) was in 1951 [1], when Industry 2.0 was at its peak and members of the Institute of Radio Engineers Industrial Electronics Group saw the changing technological landscape in electronics. Those IES pioneers established the Society to promote “industrial electronics,” which are defined by Cambridge Dictionary as electronic equipment for industrial purposes. This early vision lives on and is even more relevant today, as industry and society expect technological advances to be relevant and impactful.
- Assessing the integration of software agents and industrial automation systems with ISO/IEC 25010Publication . Karnouskos, Stamatis; Sinha, Roopak; Leitão, Paulo; Ribeiro, Luis; Strasser, Thomas I.Agent-technologies have been used for higher-level decision making in addition to carrying out lower-level automation and control functions in industrial systems. Recent research has identified a number of architectural patterns for the use of agents in industrial automation systems but these practices vary in several ways, including how closely agents are coupled with physical systems and their control functions. Such practices may play a pivotal role in the Cyber-Physical System integration and interaction. Hence, there is a clear need for a common set of criteria for assessing available practices and identifying a bestfit practice for a given industrial use case. Unfortunately, no such common criteria exist currently. This work proposes an assessment criteria approach as well as a methodology to enable the use case based selection of a best practice for integrating agents and industrial systems. The software product quality model proposed by the ISO/IEC 25010 family of standards is used as starting point and is put in the industrial automation context. Subsequently, the proposed methodology is applied, and a survey of experts in the domain is carried out,in order to reveal some insights on the key characteristics of the subject matter.
- Avaliação ambiental estratégica do programa de desenvolvimento rural de Portugal 2007-2013: ContinentePublication . Domingos, Tiago; Rosas, Cátia; Teixeira, Ricardo Miguel Sampaio; Aguiar, Carlos; Calouro, Fátima; Borges, José C.; Belo, C. Carmona; Domingos, José J.D.; Ferreira, Teresa; Freitas, Helena; Magalhães, Manuela Raposo; Ribeiro, Luis; Malcata, Francisco X.O Programa de Desenvolvimento Rural (PDR) 2007-2013 estabelece o conjunto de medidas, e dentro de cada uma destas as acções e subacções, conducentes ao cumprimento dos objectivos estabelecidos pelo Plano Estratégico Nacional (PEN) de Desenvolvimento Rural 2007-2013. O PEN surge num momento em que a situação do mundo rural português tem apresentado melhorias em termos de bem-estar social, mas ainda assim com perda de competitividade económica local e nacional e de forma assimétrica em termos territoriais. Isto é particularmente verdade para os sectores agrícola, florestal e agro-industrial, que porém falharam o objectivo essencial de criação de riqueza, sendo que os resultados mais visíveis foram a estagnação da produção e o aumento do deficit da balança alimentar. É então dentro das actividades agro-florestais que o PEN elege o seu raio preferencial de acção, dada a sua importância ao nível económico, ambiental e social. Assim, o factor determinante das políticas do próximo período deve ser o aumento da competitividade de empresas e territórios agrícolas, numa lógica de desenvolvimento sustentável. Para atingir este objectivo, é essencial que exista um forte envolvimento de todos os agentes e partes interessadas, o que requer uma aposta adicional na qualificação dos envolvidos
- Common practices for integrating industrial agents and low level automation functionsPublication . Leitão, Paulo; Karnouskos, Stamatis; Ribeiro, Luis; Moutis, Panayiotis; Barbosa, José; Strasser, Thomas I.Industrial agent technologies have been integrated in key elements coupling industrial systems and software logic, which is an important issue in the design of cyber-physical systems. Although several efforts have been tried out over the last decades to integrate software agents with physical hardware devices, and some commonalities can be observed among the existing practices, there is no uniform way overall. This work presents an empirical survey of existing practices in three application area, namely factory automation, power & energy systems and building automation. It identifies pertaining common issues and discusses how they integrate low level automation functions by utilizing industrial agents. The surveyed practices reveal high diversity, customized traditional integration focusing mostly on I/O functions, without security, and an overall approach that is mostly coupled rather than embedded.
- A community analysis of the IEEE IES industrial agents technical committeePublication . Ribeiro, Luis; Karnouskos, Stamatis; Leitão, Paulo; Strasser, Thomas I.At the dawn of the 4th industrial revolution, the use of software agents, service-oriented architectures and related technologies as primary constructs of Cyber-Physical Industrial systems is of high relevance. Current developments in this area have been consistently supported by an active community of researchers and practitioners in the past decades. Most of the main actors in the area are members of the IEEE IES Technical Community on Industrial Agents (TCIA). This work analyzes the evolution of this research and development network. It does so by identifying and investigating specialized sub-communities within the larger umbrella of Industrial Agents, their research interests and directions. In total of 7430 documents from 8045 authors were collected from the Google Scholar profiles of the TCIA members. The analysis reveals different research trends, transitions over the years and the emergence of application and domain foci, that are critically discussed.
- Educação emocional em supervisão educativa clínica: que pertinência?Publication . Ribeiro, Luis; Veiga-Branco, Augusta; Vilarinho, Mário José Medeiros; Gomes, Emília; Gabriel, Ana Júlia Colaço; Rocha, Estela; Valente, SabinaConsiderando a emergência do conceito de competência emocional nos sucessivos estudos e a natural e prévia educação emocional necessária para a adquirir, este estudo, assumiu como objetivo reconhecer a perceção dos enfermeiros portugueses acerca da pertinência da educação emocional e consequente competência emocional, como maisvalia no exercício prático da supervisão educativa clínica em enfermagem. Desenvolveu-se um estudo quantitativo, descritivo e transversal, através da aplicação de um Questionário de auto preenchimento, produzido para este efeito, a uma amostra não aleatória de 127 enfermeiros, a exercer funções no Norte (87.4%), nas ilhas (8.7%), no Centro (3.1%) e Sul (1.6%), maioritariamente do sexo feminino (80.3%), no escalão etário entre 31 e 40 anos de idade, e com formação ao nível da Licenciatura (63%) e Mestrado (25.2%). A análise dos resultados revelou que a maioria dos enfermeiros respondentes (78.5%) considera essencial a formação em educação emocional, para alguém se tornar formador em contexto clínico. No que respeita à pertinência da educação emocional no exercício de supervisão formativa no contexto da clínica, é assumidamente considerado pela maioria (83.3%) dos enfermeiros, facto relevante que sugere a inclusão deste tema na formação do supervisor. A corroborar as respostas anteriores, a maioria respondente (80.9%) considera que a educação emocional é importante. Considera-se que os resultados são evidentes, concluindo para a emergente necessidade de formação em educação emocional em enfermagem, em geral, mas sobretudo e de forma determinante, para os supervisores educativos na clínica em enfermagem.

- Industrial agents as a key enabler for realizing industrial cyber-physical systems: multiagent systems entering industry 4.0Publication . Karnouskos, Stamatis; Leitão, Paulo; Ribeiro, Luis; Colombo, Armando W.Industrial agents (IAs) [1] are multiagentbased systems (MASs) [2] that, for many years, have been advocated as a promising and realistic solution for an emerging set of industrial challenges. In the past, MASs fell into the scope of enterprise agility [3]–[8], and now, more than ever, pertain to the industrial digital transformation and sustainability spheres. MAS technology is being applied to several industrial applications in the cyber-physical system (CPS) context, namely, in smart production, smart electric grids, smart logistics, and smart health care [9]. To understand the future potential of IAs, one must first have a sufficiently concise view of the past and present efforts, i.e., understand their early applications and current directions. Such a view is necessary because, over the last decades, the concept of the IA has proven to be a bit of a moving target, adjusting to the needs, visions, and technologies of each era. As an example, Figure 1 reflects this reality well by depicting the most prevalent words in IA research articles [10] published by the IEEE Technical Committee on IAs [11], and it makes it evident that they encompass a wide range of industrial system aspects. This work presents a view of the authors and is driven by looking at past and recent efforts in the IA domain, current trends, and relevance, with key enabling features of industrial CPSs (ICPSs) [12], [13], to assess how the agent definitions, development, and solutions have changed over the years and where current efforts may focus.
- Integration patterns for interfacing software agents with industrial automation systemsPublication . Leitão, Paulo; Karnouskos, Stamatis; Ribeiro, Luis; Moutis, Panayiotis; Barbosa, José; Strasser, Thomas I.Agent-based systems, an approach derived from distributed artificial intelligence, have been introduced for designing large complex systems. They are also suitable to solve challenging problems in industrial environments, being an appropriate technologyforrealizingcyber-physicalsystems.Insuchconfiguration, they need to interface with automation and control devices. However, until now there is no widely accepted practice nor pattern to interface the software agents with the automation functions. This work addresses this issue and introduces corresponding integration patterns in order to achieve full interoperability and reusability. This work, therefore, provides a methodology for mappingexistingpracticesintoasetofgenerictemplatesandalso discusses the applicability of the proposed approach to different industrial application domains.
- Key directions for industrial agent based cyber-physical production systemsPublication . Karnouskos, Stamatis; Ribeiro, Luis; Leitão, Paulo; Luder, Arndt; Vogel-Heuser, BirgitRapid technology advances and increasing digitalization bring new opportunities but also put new challenges to modern production systems. Industrial agent concepts and technologies can be used to address the needs of modern Cyber-Physical Production Systems (CPPS). To do so, their interplay, especially in industrial settings, needs to be better understood and assessed. Key directions for investigations that are relevant for industrial agent based CPPS are analyzed in this work, mainly the design patterns, interfaces between agents and CPPS, metrics to evaluate the quality of agent based CPPS, and distributed intelligence implemented in or by agents. Although efforts exist both in agent and CPPS domains, their amalgamation still has several aspects that are under-investigated, especially when considering large-scale systems of CPPS, and the proposed four directions discussed in this work, seem promising to address several of the key underlying challenges.
