Function calculate_activity_coefficient 

fn calculate_activity_coefficient(
    asset: &Asset,
    year: u32,
    time_slice: &TimeSliceID,
    input_prices: Option<&CommodityPrices>,
) -> MoneyPerActivity

Calculate the cost coefficient for an activity variable.

Normally, the cost coefficient is the same as the asset’s operating costs for the given year and time slice. If input_prices is provided then those prices are added to the flow costs for the relevant commodities, if they are input flows for the asset.

Arguments

• asset - The asset to calculate the coefficient for
• year - The current milestone year
• time_slice - The time slice to which this coefficient applies
• input_prices - Optional map of prices to include for input commodities

Returns

The cost coefficient to be used for the relevant decision variable.
