Manufacture impact
\[
\begin{equation}
\begin{aligned}
\text{server}_\text{manufacture}^\text{criteria} & = \sum_{\set{\text{components}}}{\text{component}_
\text{manufacture}^\text{criteria}} \\ \\
& = \text{cpu_units} * \text{CPU}_{manufacture}^{criteria} \\
& \quad + \ \text{ram_units} * \text{RAM}_{manufacture}^{criteria} \\
& \quad + \ \text{ssd_units} * \text{SSD}_{manufacture}^{criteria} \\
& \quad + \ \text{hdd_units} * \text{HDD}_{manufacture}^{criteria} \\

Usage impact
Both power consumption and consumption profile are implemented.
Consumption profile
A server consumption profile is of the form :
\[
\text{CP}_{\text{component}} = \text{consumption_profile}_{\text{component}}
\]
\[
\text{CP}(\text{workload}) = (\text{CP}_{\text{CPU}}(\text{workload})
+ \text{CP}_{\text{RAM}}(\text{workload}))
* (1 + \text{other_consumption_ratio})
\]
\(\text{CP}_{\text{CPU}}(\text{workload})\) and \(\text{CP}_{\text{RAM}}(\text{workload})\) depend on the technical characteristics of the RAM and CPU. \(\text{other_consumption_ratio}\) is used to account for the electrical consumption of the other components (other than RAM and CPU). It is arbitrary set to 0.3 and can be modified by users.
