Despite the growing availability of computing resources and the use of complex models, we still suffer a lack of formal and structured tools of decision making to reduce risk, control and manage processes, in the field of integrated management systems (IMS). The aim of this work is the development of a practical user interface based on fuzzy models for risk assessment and decision-making IMS. The study encompass quality, safety and environmental (QES) management systems and provides QES evaluation criteria to select the most important features to configure the fuzzy model. In the first part of work is presented an overview on IMS and the comparison with the classical approach for risk assessment and the implemented fuzzy logic framework. In the last part follows the description of the developed tool QEST in Matlab with preliminary tests performed with simulated data.
