Measuring performance

How production performance is measured and the performance factor is calculated.

The performance factor shows how close a machine produced to its maximum speed. It is calculated per production run and feeds into the OEE as one of three components.

Calculation basis

For performance measurement, ENLYZE needs two pieces of information:

1. The actual speed achieved (measured via the configured performance parameter)

2. The maximum possible speed (the Maximum Demonstrated Speed for the respective product)

The performance factor is the ratio:

$$\text{Performance factor} = \frac{\text{Average speed during production}}{\text{MDS}}$$

The average speed refers only to productive periods. Downtimes do not affect the average speed.

Example

For Product A, the MDS is 300 kg/h. During a production run, an average of 250 kg/h was achieved.

$$\text{Performance factor} = \frac{250}{300} = 83.3\%$$

With a total quantity of 3,000 kg, this results in a performance loss of 2 hours:

• Production time at MDS: 3,000 kg / 300 kg/h = 10 h

• Actual production time: 3,000 kg / 250 kg/h = 12 h

• Performance loss: 12 h - 10 h = 2 h

Prerequisites

For ENLYZE to calculate performance, the following conditions must be met:

• A performance parameter is configured (a variable that measures production speed).

• Production run data is synchronized (so the MDS can be determined per product).

• At least one completed production run for the product exists (so an MDS value is available).
