	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.},

	abstract = {The present work proposes a computer-aided methodology for 
		designing sustainable supply chains in terms of sustainability 
		metrics by utilizing the P-graph framework. The methodology is 
		an outcome of the collaboration between the Office of Research 
		and Development (ORD) of the U.S. EPA and the research group led 
		by the creators of the P-graph framework at the University of 
		Pannonia. The integration of supply chain design and 
		sustainability is the main focus of this collaboration. The P-
		graph framework provides a mathematically rigorous procedure for 
		synthesizing optimal and alternative suboptimal networks subject 
		to multiple objectives and constraints, which include 
		profitability and sustainability in the proposed methodology. 
		Specifically, to evaluate the sustainability of a given process 
		under construction including its supply chain, sustainability 
		metrics are incorporated into the design procedure. The proposed 
		methodology is demonstrated with the optimal design of a supply 
		chain for providing heat and electric power to an agricultural 
		region with relatively limited land area where agricultural 
		wastes can potentially be recovered as renewable resources. The 
		objective functions for optimization comprise the profit and the 
		ecological footprint. The results of the study indicate that, 
		compared to using electricity from the grid and/or natural gas, 
		using renewable energy resources can yield substantial cost 
		reductions of up to 5%, as well as significant ecological 
		footprint reductions of up to 77%. It may, therefore, be 
		possible to design more sustainable supply chains that are both 
		cost-effective and less environmentally damaging. © 2012

	abstract = {Scheduling plays a key role in batch process operation; it has a 
		major effect on the process' performance. Available methods for 
		determining the optimal schedule are primarily based on either 
		MILP/MINLP formulation in conjunction with mathematical 
		programming (Floudas and Lin, 2004; Vaklieva-Bancheva and 
		Kirilova, 2010) or graph representation in conjunction with 
		combinatorial algorithms (Sanmarti et al., 2002).The current 
		work comprises three major contributions. First, an algorithm 
		has been crafted to generate a superstructure for a scheduling 
		problem. The problem is defined in the form of an S-graph 
		representing the recipe. The superstructure contains exclusively 
		every step potentially performed by any of the functional or 
		operating facilities or equipment units capable of completing at 
		least one task to be scheduled. These steps involve executions 
		of tasks and changeovers from one task to another. Second, an 
		MILP formulation is elaborated on the basis of the 
		superstructure, which guarantees the optimal solution of the 
		scheduling problem. Third, a relaxation of the MILP model is 
		incorporated into the S-graph algorithms to support the 
		selection of subproblems and decision variables in the branch-
		and-bound procedure. © 2011 Elsevier B.V.},

	abstract = {Developing energy strategies for the future is an important

		technologies and decentralized energy supply based on regional 
		resources have the potential to locally and regionally increase 
		added value, provide new jobs, decrease the dependency on 
		limited fossil resources as well as on external energy providers 
		and may have a positive impact on ecological stability. Regional 
		Optimizer (RegiOpt) software tool is based on the concept of 
		Process Network Synthesis (PNS) (Friedler et. al, 1995 and 
		Halasz et. al, 2005) and of the Sustainable Process Index (SPI) 
		(Kotscheck et. al., 1996 and Sandholzer et. al., 2005). Both 
		methodologies are combined in RegiOpt to enable the user to 
		create economically optimal sustainable energy technology 
		networks and at the same time evaluate them with respect to 
		environmental sustainability. Inputs to the software are 
		(renewable) resources (e.g. amount of crops available for 
		energetic use, biowaste, waste heat, etc.) and regional energy 
		demand profiles. Both resource provision and energy demand can 
		be provided in time dependent form. On top of that the user may 
		supply contextual information like costs and prices of 
		particular resources and services. Result of the calculation 
		with RegiOpt is the economically optimized technology network 
		that fulfils the energy needs defined by the user and renders 
		the highest regional added value. RegiOpt also provides the 
		ecological footprint according to the SPI methodology. The user 
		is able to calculate different scenarios based on different 
		input data. RegiOpt software tool will be provided in two 
		versions. Web based "Conceptual Planner" as a simple analysis 
		for regional stakeholders and an "Advanced Designer" for a more 
		detailed technology network scenario generation meant for expert 
		use. © 2011 Elsevier B.V.},
