The sustainability data is not sufficiently integrated and used for decision making. To solve this problem, organizations need information systems to facilitate their sustainability initiatives. In this study has been proposed Sustainable Enterprise Resource Planning (S-ERP) system as a holistic solution to support sustainability initiatives. The paper highlights the significance of S-ERP system and provides its future research direction to guide the academic researchers. Two research areas are included - the ERP and sustainability, to discover how academicians and practitioners solved the problems of integration and sustainability. The S-ERP systems' life cycle and identified six key areas include: concept, system design, pre-implementation, implementation, post-implementation, and system extension/retirement have been defined. They distinguish number of broad research themes based on key areas. S-ERP system appears as a promising solution to solve integration problems in sustainability; however the academic researchers need to take certain direction for assisting organizations for solving their business issues. © 2014 Elsevier Ltd.

In the proposed method, each location and passage in the building is given by a set of attributes to be taken into account in the evacuation-route planning. The evacuation time is calculated as a minimum cost of the corresponding PN ST. In addition to the globally optimal solution, the P-graph framework provides the n-best sub-optimal solutions.

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 American Chemical Society.}, year = {2013}, eissn = {1520-5045}, pages = {266-274}, orcid-numbers = {Bertók, Botond/0000-0002-1297-9792} } @article{MTMT:1892675, title = {Exhaustive identification of feasible pathways of the reaction catalyzed by a catalyst with multiactive sites via a highly effective graph-theoretic algorithm: Application to ethylene hydrogenation}, url = {https://m2.mtmt.hu/api/publication/1892675}, author = {Fan, L T and Lin, Y -C and Shafie, S and Bertók, Botond and Friedler, Ferenc}, doi = {10.1021/ie200718w}, journal-iso = {IND ENG CHEM RES}, journal = {INDUSTRIAL & ENGINEERING CHEMISTRY RESEARCH}, volume = {51}, unique-id = {1892675}, issn = {0888-5885}, abstract = {Hitherto, no attempt has been made to identify exhaustively feasible pathways for any mechanism of a given reaction catalyzed by a catalyst with multiactive sites. Two stoichiometically exact and definitely feasible mechanisms have been proposed to date for the hydrogenation of ethylene to ethane on biactive-site or triactive-site platinum catalysts. One comprises seven elementary reactions, and the other comprises eight elementary reactions; nevertheless, both mechanisms involve competitive as well as noncompetitive adsorption. Any of these mechanisms gives rise to a multitude of feasible catalytic pathways. The present work exhaustively identifies such feasible pathways by resorting to the inordinately efficient graph-theoretic algorithm based on P- graphs (process graphs). The efficacy of this algorithm has been amply demonstrated by successfully deploying it for several catalysts with single-active sites, but has never been deployed for catalysts with multiactive sites as in the current work. The availability of exhaustively identified feasible pathways for both mechanisms renders it possible to stipulate that the hydrogenation of chemisorbed chemisorbed C 2H 5 is the rate-controlling step: This step is contained in either mechanism. © 2012 American Chemical Society.}, year = {2012}, eissn = {1520-5045}, pages = {2548-2552}, orcid-numbers = {Bertók, Botond/0000-0002-1297-9792} } @article{MTMT:2060125, title = {Extending Process-Network Synthesis Algorithms with Time Bounds for Supply Network Design}, url = {https://m2.mtmt.hu/api/publication/2060125}, author = {Kalauz, Károly and Süle, Zoltán and Bertók, Botond and Friedler, Ferenc and Fan, L T}, doi = {10.3303/CET1229044}, journal-iso = {CHEM ENG TR}, journal = {CHEMICAL ENGINEERING TRANSACTIONS}, volume = {29}, unique-id = {2060125}, issn = {1974-9791}, year = {2012}, eissn = {2283-9216}, pages = {259-264}, orcid-numbers = {Kalauz, Károly/0009-0007-5888-5541; Bertók, Botond/0000-0002-1297-9792} } @article{MTMT:1690541, title = {Solving vehicle assignment problems by process-network synthesis to minimize cost and environmental impact of transportation}, url = {https://m2.mtmt.hu/api/publication/1690541}, author = {Barany, M and Bertók, Botond and Kovács, Zoltán and Friedler, Ferenc and Fan, L T}, doi = {10.1007/s10098-011-0348-2}, journal-iso = {CLEAN TECHNOL ENVIRON POLICY}, journal = {CLEAN TECHNOLOGIES AND ENVIRONMENTAL POLICY}, volume = {13}, unique-id = {1690541}, issn = {1618-954X}, year = {2011}, eissn = {1618-9558}, pages = {637-642}, orcid-numbers = {Bertók, Botond/0000-0002-1297-9792} } @article{MTMT:1695506, title = {Optimal Design of Supply Chains by P-garph Framework under Uncertainties}, url = {https://m2.mtmt.hu/api/publication/1695506}, author = {Süle, Zoltán and Bertók, Botond and Friedler, Ferenc and L T, Fan}, doi = {10.3303/CET1125076}, journal-iso = {CHEM ENG TR}, journal = {CHEMICAL ENGINEERING TRANSACTIONS}, volume = {25}, unique-id = {1695506}, issn = {1974-9791}, year = {2011}, eissn = {2283-9216}, pages = {453-458}, orcid-numbers = {Bertók, Botond/0000-0002-1297-9792} } @article{MTMT:1674668, title = {Minimising carbon footprint of regional biomass supply chains}, url = {https://m2.mtmt.hu/api/publication/1674668}, author = {Lam, H L and Varbanov, Petar and Klemeš, Jiri Jaromir}, doi = {10.1016/j.resconrec.2009.03.009}, journal-iso = {RESOUR CONSERV RECY}, journal = {RESOURCES CONSERVATION AND RECYCLING}, volume = {54}, unique-id = {1674668}, issn = {0921-3449}, abstract = {A new method for regional energy targeting and supply chain synthesis is presented.

A new algorithm for revealing energy supply chain clusters is introduced, described and illustrated by a case study. It has been developed on two levels. The first is a top-level supply chain network with lowest Carbon Footprint generated. It consists of a number of zone clusters. The definition of zones is provided; it can be e.g. a village or a town. Each zone is considered as a unit. At the second level is a supply chain synthesis carried out by P-graph based optimisation within each cluster. It provides a more detailed analysis. The use of the P-graph framework as a synthesis toolset provides a strong mathematically proven fundament for handling the complexity of the synthesis problem. It contributes to the optimal network design with a high computational efficiency. This approach contributes to the cleaner generation of energy from biomass, approaching CO2 neutrality as much as possible.
