Omax and Fuzzy Logic as Productivity Tools and Ergonomic Analysis in Automotive Maintenance

Abstract

Productivity is today an important factor in the growth of companies, for this, it is necessary to have an adequate ergonomic environment for the sake of workers. This work aims to show the use of the Objective Matrix (OMAX) and the analysis of environmental conditions from the use of fuzzy logic to determine the behavior of factors such as temperature, noise and lighting and its direct effect on productivity from the workers. A group of employees from the maintenance area in an automotive agency that offers mechanical washing and maintenance services was analyzed. With the OMAX method, the level of productivity was determined for a predetermined time by analyzing fatigue and physical wear for certain schedules. According to the Mexican regulations established by the Ministry of Labor and Social Welfare (STPS by its acronym in Spanish), it is necessary to comply with some requirements that are established by law, so once the current environmental conditions were analyzed based on the use of fuzzy logic, an adjustment based on regulations, making the changes required to subsequently measure the final result with OMAX, which showed a productivity increase.
