Increasing the productivity of a facility is the focus of many companies. The OEE provides an overview of where productivity can be increased and to what extent. The approach is systematic. Commencing with the available production time, the total time during which production can be carried out in a plant or with a machine is first determined. For example, a machine can operate for 20 hours a day. However, due to various technical malfunctions and the associated repair work, the machine runs for only 16 hours. Therefore, there is a loss of 20%. Since this machine requires maintenance in several shifts, the daily loss due to the changeover time is 48 minutes and consequently another 5%. During this period, the company will produce 250 units, of which 5 units will have to be sorted out due to various production errors. So, 2% of the produced number of units are lost every day. The OEE calculation therefore looks as follows:
OEE = 80% x 95% x 98% = 74,48%
The company’s task is to improve the OEE score to 74.48%. The high failure during production time stands out in this context. By Using the software, such as the OPC Router, breakdowns can be noticed and fixed faster. Different services can notify the mechanic quicker to stop production, indicate a failure, and assist in repair. That would already greatly benefit the production in this example. Reducing downtime from two hours to one hour would increase the OEE score to 83.79%, almost an increase of 10%.
