Abstract
The research is based on the study of the probability with which an equipment works adequately in a certain period under specific operating conditions, the reliability analysis carried out on a semiautomatic screen printing machine, allows to verify the availability of the equipment in the execution of works inherent to it and therefore optimize the mechanism and offer products that meet market requirements, for this we must know the correct times in which preventive maintenance will be carried out, this study was carried out through the application of distribution Weibull and exponential with which it was possible to determine that the value of the reliability for the two distributions is very similar with an approximate of 65%. It was also possible to determine that the reliability of an element will decrease as a function of time due to the wear that it will present due to the constant use of the constituent elements of the machine. On the other hand, according to the analyzes carried out, it is determined that the machine has an availability of 97.75%, to carry out the jobs entrusted to screen printing. Finally, a maintenance program is
