The allowable increase and decrease of the constraints determine the range of changes to the constraints coefficient without changing the optimal solution constraints RHS value without changing the optimal solution constraints coefficient without changing the optimal objective function value constraints RHS value without changing the shadow price The shadow price is how much the optimal objective function value will change given one unit of change to the RHS value of a constraint how much the optimal solution will change given one unit of change to the RHS value of a constraint how much the optimal solution will change given one unit of change to the coefficient of a constraint how much price the solution costs
