# MANUFACTURE METHODOLOGY

Manufacture impacts are measured at components and device level with a bottom-up approach.

## Allocation

Manufacture impacts can be reported with several allocation strategies.

### Hover the lifecycle - Allocation: TOTAL

The total manufacturing impacts are reported independently of the usage.

manufacture_impact = total_impact

### Hover a specific duration - Allocation: LINEAR

The manufacturing impacts is linearly distributed hover the life duration of the devices. The impacts are reported hover the usage duration.

manufacture_impact = total_impact * (usage_duration/life_duration)

## Variable components impacts

The impact of variable components are evaluated from the components characteristics.

## Fixed components impacts

The impact of fixed component are set by default

## Device impacts

Device impacts is evaluated from the sum of the impacts of its components. Other treatments can be applied depending on the device.
