Equipment quality management based on a mathematical model to detail its life cycle

The equipment quality management program at the production stage provides for the use of statistical information on the most characteristic conditions of equipment during its operation as initial data. In this assessment, both operational and reliability characteristics of the equipment are subject, which are the criteria for establishing mutual compliance of the conditions of its production with real operating conditions. In accordance with the foregoing, the basis for the implementation of equipment quality regulation is its failure flow of abnormally high intensity. At the same time, two particular cases of high failure rate are distinguished: as the first one, a mismatch of the production conditions of the equipment with the current technical requirements is accepted, the result of which is products with a hidden factory defect. As practice shows, it is impossible to establish its presence with high accuracy as a result of performing input control, which leads to equipment failures during operation at various operating times. The second one is the discrepancy between the production conditions of the equipment and the actual operating conditions. In this case, due to the design features, the equipment is not able to withstand typical operational loads, which causes a high failure rate.
