substituting the coordinates of each corner point into the objective function to determine which corner point is optimal
feasible solution space
the set of all feasible combination of decision variables as defined by the constraints
graphical linear programming
graphical method for finding optimal solutions to two-variable problems
range of feasibility
range of values for the RHS of a constraint over which the shadow price remains the same
range of optimality
range of values over which the solution quantities of all the decision variables remain the same
a constraint that does not form a unique boundary of the feasible solution space
assessing the impact of potential changes to the numerical values of an LP model
amount by which the value of the objective function would change with a one-unit change in the RHS value of the constraint.
a linear programming algorithm that can solve problems having more than two decision variables
when the values of decision variables are substituted into a greater than or equal to constraint the amount by which the resulting value exceeds the right-hand-side value.
