Resiliência e Fragilidade dos Sistemas de Trabalho e Sustentabilidade: estudos de casos de sistemas sócio-técnicos complexos no Brasil na área nuclear, avia o e emergência

Resilience Engineering aims to make people and organizations sensitive to the risk models adopted and to the adaptive strategies used to control the emergency and failure paths. A resilient organization must provide means to manage the adaptations by monitoring, understanding, reflecting and learning from these strategies, and by identifying threats and risks to safety. The failure to apply such principles leads the organization to act in a reactive model, in an endless fight against danger. The case studies presented in this article seek to apply the concepts and methods of resilience engineering, relating them to the concept of complex socio-technical systems′ sustainability, in a recently industrialized country like Brazil. The cases approach the domains of nuclear, aviation, and emergency, using Cognitive Task Analysis as the methodological basis. The studies have allowed identification of the resilience and brittleness factors in several domains researched, pointing out that a proactive safety management system based on resilience engineering concepts may provide the organizations with an effective means to balance safety and productivity goals.
