You are the manufacturing engineer at Acme Corp. The packaging machine is producing below its expected capability. You have been asked to improve the capability of the machine. As initial metrics for the improvement effort, you have decided to calculate the overall equipment effectiveness (OEE) and the mean time between failure (MBTF) for the packing machine. You have collected the following information: The packing process operates two 8-hour shifts/day. Each shift, the operation is shut down for 30 minutes for breaks and for 30 minutes for a shift meeting. In addition, there are typically 30 minutes of unplanned downtime each day. When the packing machine was purchased, the theoretical cycle time was specified as 0.01 hours/unit. The current average daily production rate is 700 units/day. Losses in output are due to stoppages and minor adjustments. Out of the daily production of 700 units, approximately 15 units are rejected due to operator error in correctly aligning the package in the packaging machine and 15 units are rejected due to damage caused by unexpected failures of the packaging machine. 1) What is the OEE for the counter? Show the following intermediate calculations for credit: Availability, Performance Efficiency, and Quality. Show all work and include units in all calculations.
2) What is the MBTF? Show the following intermediate calculations for credit: Total Running Time and Number of Failures. Show all work and include units in all calculations.
