lumix.analysis.sensitivity.LXConstraintSensitivity¶

class lumix.analysis.sensitivity.LXConstraintSensitivity(name, shadow_price=None, slack=None, allowable_increase=None, allowable_decrease=None, is_binding=False, is_active=False)[source]¶

Sensitivity analysis results for a constraint.

Parameters:

name (str)

name¶: Constraint name

shadow_price¶: Shadow price (marginal value of relaxation)

slack¶: Slack or surplus value

allowable_increase¶: Maximum RHS increase before basis change (if available)

allowable_decrease¶: Maximum RHS decrease before basis change (if available)

is_binding¶: Whether constraint is binding (tight)

is_active¶: Whether constraint is active at optimum
