THE IMPACT OF MODERNIZATION ON THE PRODUCTIVITY OF A MULTI-STAGE PRODUCTION OF TRANSFORMER SHEETS

Production is concerned with short throughput times and high schedule reliability in order to on the one hand, fulfill customer demands and on the other hand, increase planning reliability. However, from the business perspective, it is preferred that the available production equipment is highly utilized and that there is the lowest possible WIP (Work in Process) level. For the evaluation system used in the study TPM method. The TPM method most commonly employs three indicators: MTTR, MTBF and most typically - OEE. The first two are associated exclusively with technical issues of the examined production line. The object of the study was the production plant of transformer sheets. The article presents parts of research OEE performance indicator for many production lines. In particular was examined the impact of modernization of the line on the efficiency.
