Methodology to Measure Reliability in Assembly Lines
Abstract
Measurement is a key aspect to evaluate the result of any process. Assembly lines should be measured considering the reliability of both the product and the production process. The purpose of this study was to develop a methodology that would allow knowing the status of an assembly line and that would integrate a measurement model to obtain a reliability index for a line of this type in the automotive industry. The two products resulting from this study were the methodology with its structure in stages and the mathematical model. The methodology is composed of five stages and the model of four elements. Reliability could be calculated for an automotive assembly line using the mean of the best fit distribution. This made it possible to detect the index that most affected general reliability. The index that most affected the general reliability value was availability with 75.55 %, followed by the efficiency index with 87.25 %, continuing with the quality index with 90.15 % and, finally, with the least effect, is the index of delivery capacity with 97.75 %.
