This document summarizes the formulas used to define key metrics in the Global KPIs Solution when calculating Area Utilization for Mechanicals.

## Time and calendar conventions

- All times are calculated in a site's local time in its own time zone.
- A site's "day" begins at the start of the first scheduled working hour and continues for the next 24 hours. So if a site's first shift starts at 5:00 a.m. local time, the site's 24-hour "day" runs from 5:00 a.m. to 4:49 a.m. the next morning.
- Weeks run from Sunday 12:00 a.m. through Saturday 11:59 p.m. in local time.

## Machine KPIs

### Machine Utilization (MU) (in %)

Machine Utilization (%) is the total number of units divided by the Target number of units, assuming the machine runs 24 hours a day, 365 days a year. It is calculated as Actual Units / Target Units, expressed as a percentage.

### Availability (in %)

The % of Planned Production Time during which production took place. Measured in 15 minute intervals. If any production takes place during the 15 minute interval, the machine is considered "available."

### Throughput (in units)

Units made during period.

### Speed (in units per hour)

Throughput during period divided by Actual Production Time (hours of Availability) during period.

### Target

Target is the derated Target for the machine in units per hour.

### Performance (in %)

Performance measures what percentage of the Target the machine achieved when it was producing (Actual Production Time).

## Area KPIs

### Area Utilization (AU) (in %)

Area Utilization is the total number of units produced by all Machines during the period, divided by the sum of the Target number of units for all Machines, assuming the Area runs 24 hours a day, 365 days a year. It is calculated as Actual Units / Target Units, expressed as a percentage.

### Availability (in %)

The % of Planned Production Time during which production took place. Measured in 15 minute intervals. If any production takes place during the 15 minute interval, a Machine is considered "available." Availability is averaged over the period for all the Machines in the Area to produce Availability for the Area.

### Throughput

Units produced during the period. Throughput is summed over the period for all the Machines in the Area. In the user interface, Target production for the period is shown underneath. The progress bar divider shows progress towards 100% of Target production.

## Site KPIs

### Area Utilization (AU) (in %)

Weighted average Utilization across all Machines in the Site during the period. Area Utilization is the total number of units produced by all machines, divided by the total Target number of units for all Machines, assuming the Area runs 24 hours a day, 365 days a year. It is calculated as Actual Units / Target Units, expressed as a percentage.

### Availability (in %)

Simple average Availability across all Machines at the Site during the period. A Machine is Available during a 15 minute interval if any production occurred. Availability is measured over scheduled work hours.

### Throughput

Total Throughput across all the Areas during the period.

### Number of Areas

Number of Areas that were included in the Area Utilization calculation for this site during the period.

## Regional KPIs

- AU is weighted average Utilization across all Machines in the Region during the period, calculated in the same way as described for the Site, above.

## Global KPIs

- AU is weighted average Utilization across all Machines globally during the period, calculated in the same way as described for the Site, above.
