Abstract
The article aims demonstrate the importance of reliability mapping for decrease risks of shutdown and accident in critical activities. For mapping is needed to know the operational context, considering culture and deviations that between with other factors will be occasion total failure. The analyses of sociotechnical reliability need of mapping of human, operational, process and equipment reliability to occur, besides considering the system complexity and the social attractiveness, for that this way be possible the elaboration of efficient barriers. The reliability mapping demands tools in the area of social and human risk analysis, analysis of the task with the evaluation of the environment of the activities, project of work, analysis of human factors, identification of work behaviour for cultural transformation, leadership style for process safety, culture of guilt and fair culture, dynamic risk management, energy reliability and good energy practices. The Socio Technical Reliability Analyses – STRA is a more complete tool for the analyse of systems and decrease of risks. With this mapping, it is possible to identify the industrial areas that have the greatest influence on the losses occurred in the industrial context, after that it is possible use the information for make an using fault tree analyses & decision diagram. That provides for the manager makes decisions with a solid knowledge base. The methodology aims through application of tool, demonstrate the use in analyses of parameters and construction of sociotechnical reliability mapping, identifying the tasks, equipment and process that cause shutdown. After reliability assessment, it continued with barriers analysis using fault tree analyses & decision diagram tool. The conclusion is about understand different cause considering STRA and demonstrate the decision-making processes importance to take corrective and preventive actions.
