Optimization with absolute values is a special case of linear programming in which a problem made nonlinear due to the presence of absolute values is solved using linear programming methods. GLPK supports the GNU MathProg modeling language, which is a subset of the AMPL language. The question seems to be asking only about the environmental impact of the cartridges, so I probably shouldn't talk about how a laser printers use 100 times more power while they are printing, but allow me just to say that for the whole life cycle the most significant stage for both types is paper usage, followed by the manufacturing of the product and electricity consumption. py you will see that after the model is built the gurobi variables and model are attached to the pulp variables and model. As a quick review, an optimization model is a problem which has an objective (or a set of objectives in multi-objective programming), a set of constraints, and a set of decision variables.
