simply net marginal revenues (i.e., marginal revenue minus marginal cost). For the basic variables x1 and x3, the reduced costs are zero, c1 =6 −11(1 2)− 1 2 (1) =0, c3 =13 −11(1)−1 2 (4) =0. The values imputed to the resources are such that the net marginal revenue is zero on those activities operated at a positive level. That is, for ...
