	abstract = {The P-graph framework introduced by Friedler et al. (Chem Eng Sci. 1992;47:1973-1988) is a general mathematical methodology based on Graph Theory which is applicable to many process design problems. We propose an extension of the P-graph framework and the associated MILP model to account for operating units and systems where the inputs and outputs are variable. This is important because the P-graph framework in its current form would otherwise apply only to systems where the ratios of inputs to outputs are fixed. Consequently, it is difficult to apply the method to many emerging systems without the new mathematical model presented here. We discuss and develop the model in detail, and we then illustrate its application with the case study of an energy system. We establish a structure with optimal cost for a baseline heat demand, and we further explore how the energy system structure and the feedstocks change as the heat demand increases. © 2016 American Institute of Chemical Engineers.},

Finally, in light of the tenet of a modeling- transformation-evaluation paradigm, an appraisal is made of the feasibility as well as the flexibility and cost of the optimal OMACS-based design configuration obtained. © 2015 Budapest Tech Polytechnical Institution.

	abstract = {Abstract We present a computer-aided methodology for designing sustainable supply chains using the P-graph framework to develop supply chain structures which are then analyzed using cost, the cost of producing electricity, and two sustainability metrics: the ecological footprint and the emergy input. These metrics respectively represent environmental burden in terms of land use and energy resources. The results are the continuation of a research effort between members of the Office of Research and Development (ORD) of the U.S. EPA and the University of Pannonia. In earlier work, the basis of the research, the integration of supply chain design and sustainability were presented. There, the P-graph framework provided a mathematically rigorous procedure for synthesizing optimal and alternative suboptimal networks subject to profitability and ecological footprint criteria. In this work the effort is extended with another sustainability metric, emergy. Emergy, a measure of the energy used up in transformations directly and indirectly to make a product or maintain a service, was assessed for each energy production supply chain. The proposed methodology demonstrates the optimal design of a supply chain which provides electric power and heat to an agricultural region with agricultural wastes that can potentially be recovered as renewable resources. The results of the study indicate that, compared to using electricity from the grid and/or natural gas, renewable energy resources can yield substantial cost reductions of up to 17%, as well as significant ecological footprint and emergy reductions. These results indicate that it is possible to design more sustainable supply chains that are also cost-effective.},

	abstract = {The primary aim of process-network synthesis, or PNS in short, is to determine the best process network achieving a desired goal, e.g., producing a set of desired products or satisfy demands. PNS has a long history, and numerous methods for executing it are available. Its acceleratedly increasing importance can be attributed to the need to respond to the rapid emergence of new technologies and fast changes in the economic environment. It is highly desirable that any corporation be able to ascertain if a new technology is viable for its business as well as to assess if its current technology remains sustainable in the changing environment. Herein, a novel method and software for PNS are proposed for generating, optimizing, and analyzing alternative process designs at the conceptual level. The method is illustrated by synthesizing alternative process designs with different network structures for the production of butanol, ethanol, and acetone from grains. Furthermore, the sustainability of the resultant process designs is analyzed. This is executed by varying the payout period and the production rate, i.e., load. © 2012 American Chemical Society.},
