Abstract: Industrial Ecology is a systemic/multidisciplinary discourse dedicated to the optimization of energy and material flows through an industrial domain, mapped as a network of processes that extract/modify natural resources, thus interconnected with the environment, where residues/wastes are also discharged. This optimization is examined in the present work by using energy/materials saving (E/M) and sustainable development (S) as main factors. In an attempt to investigate the relation between these factors, we set S as the dependent variable (output) and a composite index I, based on the weighted combination of E and M, as the independent variable (input). The optimal value Iopt is found at the minimum value Smin of the objective function S(I), which consists of two conflict variables S1 and S2, based on the beneficial action of energy/materials saving and the flexibility decrease (due to sacrifice of degrees of freedom to obtain higher I-values, implying also higher compactness of the industrial processes network), respectively. Since the demand for energy/materials depends also on the level of S, which is changing in the time course, we should deal with an implicit function of the form f (S, E, M) = 0 rather than with an explicit function of the form S = f (E,M). Therefore, we can obtain an internal triangular relation between S, E, M, having a gravity center near the variable playing the most significant role. Nevertheless, we can reduce the generalized implicit function to its corresponding explicit form by setting the variable to be interconnected mostly with the strategic task as the depended one. Three case examples are presented to illustrate real situations, where S, E, M, correspond to a strategic target set a priori, respectively.
