This paper proposes a methodology based on fuzzy logic to evaluate noise quality in industrial workplaces, considering variables such as noise level and working hours. The model uses membership functions and fuzzy rules to classify the environment as "satisfactory" or "at risk." The application of the method in a metalworking industry demonstrated its effectiveness in identifying unhealthy conditions, contributing to the prevention of occupational health problems.

This paper presents the study of a low-voltage three-phase system with harmonic distortion using fuzzy logic applied to the power factor. The objective is to reduce losses in the installation, voltage drops, and underutilized capacity, optimizing electricity usage and providing benefits to both the company and the utility.
