This document summarizes the formulas used to define key metrics in the Global KPIs Solution Line Utilization calculations.

## 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 placements divided by the theoretical Target number of placements, assuming the machine runs 24 hours a day, 365 days a year. It is calculated as Actual Placements / Target Placements.

### 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 (during scheduled work hours), the machine is considered "available."

### Throughput (in placements)

Placements made during period.

### Speed (in placements per hour)

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

### Target

For a PnP machine, Target is the derated Target for the machine and head in placements per hour.

### Performance (in %)

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

## Line KPIs

### Line Utilization (LU) (in %)

Line Utilization is the total number of placements divided by the theoretical Target number of placements, assuming the line runs 24 hours a day, 365 days a year. It is calculated as Actual Placements / Target Placements, 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 (during scheduled work hours), the machine is considered "available."

### Throughput

Placements made during period. (Target production for the period is shown underneath. The progress bar divider shows progress towards 100% of Target production.)

## Area KPIs

- Throughput is summed over the period for all the Lines in the Area
- Utilization and Availability are averaged over the period for all the Lines in the Area.

## Site KPIs

### Utilization (in %)

Weighted average Line Utilization across all the LU Lines during the period. Line Utilization is the total number of placements by all Lines in the Site divided by the total Target number of placements across all Lines, assuming all Lines run 24 hours a day, 365 days a year. It is calculated as Actual Placements / Target Placements, expressed as a percentage.

### Availability (in %)

Simple average Availability across all the LU Lines at the Site during the period, expressed as a percentage. A Line is Available during a 15 minute interval (during scheduled work hours) if any production occurred. Availability is measured over scheduled work hours.

### Throughput

Total Throughput across all the LU Lines during the period.

### Number of LU Lines

Number of Lines that were included in the Line Utilization calculation for this site during the period.

## Regional KPIs

- Weighted average Line Utilization across all the LU Lines in the Region during the period, calculated in the same way as described for the Site, above.

## Global KPIs

- Weighted average Line Utilization across all the LU Lines in the Region during the period, calculated in the same way as described for the Site, above.
