DualSignals.jl - Julia package for standardized extraction and decision-support reporting of shadow prices (duals) and constraint tightness from network and equilibrium models.

DualSignals.jl standardizes extraction and decision-support reporting of dual variables (shadow prices / Lagrange multipliers) and constraint tightness from solved optimization and equilibrium models. It is designed to work across networked infrastructures and general equilibrium applications by using a simple, portable data model: components ⇄ constraints ⇄ duals.
