ask_market

Per-market ASK models for use when a MarketManager is loaded.

Two classes:

• ASKMarket — ASK for one passenger market.
• ASKAggregator — sums per-market ASKs into the total ask consumed by downstream models.

All use model_type="custom" (AeroMAPSCustomModelWrapper). Input/output names are built from the market id at construction time.

ASKMarket

ASKMarket(name, market_id, *args, **kwargs)

Bases: AeroMAPSModel

ASK for one passenger market: <mid>_ask = <mid>_rpk / (<mid>_load_factor / 100).

Parameters:

Name	Type	Description	Default
name	str	Discipline name.	required
market_id	str	Market identifier (e.g. 'short_range', 'domestic').	required

compute

compute(input_data)

Compute ASK for one passenger market from RPK and load factor.

Parameters:

Name	Type	Description	Default
input_data	dict	Inputs containing market RPK and load factor series.	required

Returns:

Type	Description
dict	Output dictionary with the market ASK series.
