Total Production Management reporting can be used to quickly identify problems. The primary statistic ‘OEE’ (Overall Equipment Effectiveness) is calculated as:
OEE = Utilisation x Efficiency x Quality Rate [85% is world class]

What can you expect from a TPM system
The TPM Audit1000 software collects machinery data in real time, and turns it into valuable information, viewed on a secure web-site, from your desk-top PC or the PDA in your pocket.
Information includes:
· Utilisation
· Efficiency
· Quality Rate
· Loss Measurements
· Automatic Line Stoppage Logging
· Fault Logging
· Batch Recording
All these parameters are recorded by batch, shift and day.
OEE summary reports speedily highlight line problems:

This report shows a low utilisation figure for batches 381 & 382. Analysis of these batches indicates that these products caused the assembly machine to jam.
This evidence can be used to identify problems, cost losses, re-schedule production, etc.
Managers now have better control of the assembly lines and can answer with confidence:
- How many did we make?
- How much did it cost?
- Can we reach our targets on time?
