Confiabilidade humana: conceito qualitativo aplicado a metrologia e topografia a laser

Abstract

The technology related to metrology and topography that uses laser-Tracker is relatively new in the industry; equipment operators need training and to follow the standards for measurements. The operators as well as the equipment are often exposed to several situations in an industrial environment, these factors will be related to the human reliability demonstrated in a qualitative way. The study environment is a Continuous Casting Segment Workshop of a large steel mill company located at Serra, State of Espírito Santo. The operators are service providers of a certain company with a headquarter at São José dos Campos, State of Sao Paulo, and a branch located also at Serra. The services are routine, standardized and refer to the alignments of the Segments of the Continuous Casting Machine. The Industrial environment, weather, operators and the equipment are some of the factors that can affect a metrological service. Human reliability should begin to be studied by this company during these services in a qualitative way, since these factors can cause deviations during the measurements and allow opportunity for possible errors. Therefore, it is necessary to understand the factors that affect human reliability during measurements and to find ways to minimize or eliminate these factors.
