Solver Configuration

Customise operational constraints, cost weights, and recovery strategies.

Overview

The SolverConfig object controls how the Pleiades solver approaches disruption recovery. It's passed as an optional field in the simulation request. All fields have sensible defaults — you only need to specify the values you want to override.

SolverConfig

Field	Type	Default	Description
`operational`	`OperationalConfig`	See below	Operational constraint parameters
`costs`	`CostWeights`	See below	Cost weights for the objective function
`strategies`	`string[]`	All four strategies	Which recovery strategies to evaluate

OperationalConfig

These parameters define the physical and regulatory constraints of the operation.

Parameter	Type	Required	Description
`turn_minutes`	integer= 35	Optional	Minimum aircraft turnaround time between flights, in minutes.
`time_block`	integer= 5	Optional	Delay granularity in minutes. All delays are multiples of this value.
`max_runtime`	integer= 30	Optional	Maximum solver runtime in seconds. Higher values may find better solutions.
`reaccom_window`	integer= 720	Optional	Re-accommodation window in minutes (12 hours). If a delay exceeds this, cancellation is forced.
`reaccom_hotel_threshold`	integer= 720	Optional	Wait time threshold at which hotel accommodation costs apply (minutes).
`crew_brief_min`	integer= 60	Optional	Crew briefing time before first flight in a duty period (minutes).
`crew_debrief_min`	integer= 30	Optional	Crew debriefing time after last flight in a duty period (minutes).
`max_crew_duty_min`	integer= 840	Optional	Maximum crew duty period in minutes (14 hours = 840 minutes).
`crew_connect_min`	integer= 30	Optional	Minimum crew connection time between consecutive flights (minutes).
`duty_split_layover_min`	integer= 120	Optional	Layover duration that splits into a new duty period (minutes).
