If the change to a right-hand side is within the allowable range, the value of the shadow price remains valid.

Question

Quizplus · Accepted Answer

If the change to a right-hand side (RHS) is within the allowable range (also called the range of feasibility), it means that the current optimal solution remains feasible and the same set of binding constraints still hold. Hence, the shadow price values calculated based on the current optimal solution and binding constraints are still valid within the same range of feasibility. However, if the change to the RHS causes the model to become infeasible or changes the set of binding constraints, the shadow price values may become invalid.
