The structuring of the petrochemical industry has been considered both as a single objective and as a multiobjective problem. Three objective functions have been considered: The maximization of the thermodynamic availability change, the minimization of the lost work and the minimization of the feedstock consumption. The first two objectives aim at structuring the industry for "optimum" energy utilization, while the third aims at the optimum utilization of raw materials. The single objective analysis provided three optimum structures that constitute bounds of the actual performance of the petrochemical industry. The multiobjective analysis on the other hand provides the process designer a set of alternative solutions and subjective criteria have to be used in order to select the "best".
