“…In this way, the criticality of IS is considered as their resilience to faults. Faults specification is provided in [ 49 ] with a division to hardware, environmental, and cognitive faults in systems and possible detection methods. A set of definitions, including adaptability, sustainability, complexity, etc., is described in the context of a framework, aimed at developing digital ecosystems [ 50 ].…”

Distributed intelligent systems (DIS) appear where natural intelligence agents (humans) and artificial intelligence agents (algorithms) interact, exchanging data and decisions and learning how to evolve toward a better quality of solutions. The networked dynamics of distributed natural and artificial intelligence agents leads to emerging complexity different from the ones observed before. In this study, we review and systematize different approaches in the distributed intelligence field, including the quantum domain. A definition and mathematical model of DIS (as a new class of systems) and its components, including a general model of DIS dynamics, are introduced. In particular, the suggested new model of DIS contains both natural (humans) and artificial (computer programs, chatbots, etc.) intelligence agents, which take into account their interactions and communications. We present the case study of domain-oriented DIS based on different agents’ classes and show that DIS dynamics shows complexity effects observed in other well-studied complex systems. We examine our model by means of the platform of personal self-adaptive educational assistants (avatars), especially designed in our University. Avatars interact with each other and with their owners. Our experiment allows finding an answer to the vital question: How quickly will DIS adapt to owners’ preferences so that they are satisfied? We introduce and examine in detail learning time as a function of network topology. We have shown that DIS has an intrinsic source of complexity that needs to be addressed while developing predictable and trustworthy systems of natural and artificial intelligence agents. Remarkably, our research and findings promoted the improvement of the educational process at our university in the presence of COVID-19 pandemic conditions.

“…Tais soluções têm como objetivos assegurar a alta disponibilidade, confiabilidade, segurança, portabilidade e agilidade dos sistemas de informações, assim como prover mecanismos que permitam a identificação e a rápida recuperação em caso de falhas. As falhas em sistemas de informação, em geral, são derivadas de: (a) problemas de hardware e software; (b) falhas provocadas por agentes externos à solução de sistema; e (c) falhas cognitivas geradas quando uma ação prevista pelo sistema não é realizada, ou, ainda, a ação gerada não é a esperada e impossibilita a solução de um dado problema (Perraju, 2001).…”

As transformações do varejo, impulsionadas pelos altos volumes negociados, a globalização e as novas tecnologias, têm exigido um desempenho cada vez melhor das aplicações de Tecnologia da Informação (TI), tornando-as críticas às operações de negócio. Para lidar com essa nova realidade, a implementação de sistemas de monitoração proativos dos processos varejistas tem aumentado com o objetivo de prover maiores disponibilidade, confiabilidade e segurança das aplicações, ampliando, assim, a discussão de projetos dessa natureza e ligando a gestão de projetos à estratégia de negócios. O trabalho desenvolvido por Shenhar et al. (2005) apresenta um framework para desenvolvimento dessa abordagem denominado Estratégia de Projetos. Nesse contexto, este artigo tem como objetivo apresentar as contribuições da gestão estratégica de um projeto de TI em uma empresa multinacional de varejo, sob uma perspectiva que vai além da análise da tríplice restrição. Por meio de estudo de caso único, foi possível verificar que a abordagem da gestão estratégica de projetos mostrou-se eficiente durante as etapas de seleção e gestão de projetos devido ao alinhamento do projeto aos objetivos de negócios, contribuindo também o incremento da visibilidade do valor de TI à organização. Palavras-chave: varejo; missão crítica; tecnologia da informação; gestão estratégica de projetos; valor de TI.

“…However, in real-world and real-time applications, these complex systems encounter very different working conditions that influence their operating characteristics and their behaviors. These configurations may unfortunately lead to errors, critical states, or failures [2,3]. Moreover, these systems, often non-linear, have high-frequency operating characteristics with continuously changing specifications.…”
