The optimal evacuation plan depends on the types and locations of threats in addition to the site's layout; moreover, it is necessary to determine the plan in real time when the events are detected. In such emergency scenarios, determining an optimal or near optimal plan, in terms of the egress time, entails the evaluation of numerous alternative evacuation routes. This problem is highly convoluted because of its combinatorial nature; thus, it is highly desirable or even essential, to have access to optimization techniques to solve it. In the present contribution, an algorithmic optimization method is presented to plan evacuation strategies in the chemical industry, in terms of the egress time, supported by software tools. This method uses the graph-theoretic approach based on P- graphs, which exploits the combinatorial nature of the problem, thus providing optimal solutions with high computational efficiency. The method is illustrated by applying it to the evacuation of various industrial site configurations.}, keywords = {Combinatorial optimization; Process-network synthesis; P-graph; Building evacuation route planning; Chemical Complexes}, year = {2020}, pages = {1-6}, orcid-numbers = {Bertók, Botond/0000-0002-1297-9792} } @misc{MTMT:30729128, title = {P-graph approach for enhancing the sustainability of benzaldehyde production from toluene via Reaction-Network Synthesis}, url = {https://m2.mtmt.hu/api/publication/30729128}, author = {Pimentel, J. and A., Argoti and I., Gil and Heckl, István and Bertók, Botond and Friedler, Ferenc and Garcia Ojeda, Juan Carlos}, unique-id = {30729128}, year = {2018}, orcid-numbers = {Bertók, Botond/0000-0002-1297-9792} } @mastersthesis{MTMT:3237541, title = {On modeling building-evacuation-route planning and organization-based multiagent systems by resorting to the P-graph framework = Épület kiürítési útvonalak tervezése és szervezeti alapú, multiágens rendszerek modellezése a P-gráf keretrendszer felhasználásával}, url = {https://m2.mtmt.hu/api/publication/3237541}, author = {Garcia Ojeda, Juan Carlos}, doi = {10.18136/PE.2016.630}, publisher = {University of Pannonia}, unique-id = {3237541}, year = {2017} } @misc{MTMT:30729181, title = {Process­network Synthesis for Benzaldehyde Production: P­graph Approach}, url = {https://m2.mtmt.hu/api/publication/30729181}, author = {Losada, J.P. and Heckl, István and Bertók, Botond and Friedler, Ferenc and Garcia Ojeda, Juan Carlos and A., Argoti}, unique-id = {30729181}, year = {2015}, orcid-numbers = {Bertók, Botond/0000-0002-1297-9792} } @inproceedings{MTMT:3031466, title = {Identifying evacuation routes via the P-graph methodology}, url = {https://m2.mtmt.hu/api/publication/3031466}, author = {Garcia Ojeda, Juan Carlos and Bertók, Botond and Friedler, Ferenc and Argoti, A}, booktitle = {2015 10th Computing Colombian Conference (10CCC 2015)}, doi = {10.1109/ColumbianCC.2015.7333443}, unique-id = {3031466}, year = {2015}, pages = {339-346}, orcid-numbers = {Bertók, Botond/0000-0002-1297-9792} } @article{MTMT:2941194, title = {Process Network Synthesis for Benzaldehyde Production: P-graph Approach}, url = {https://m2.mtmt.hu/api/publication/2941194}, isbn = {9788895608365}, author = {Pimentel, Jean and Heckl, István and Bertók, Botond and Friedler, Ferenc and Garcia Ojeda, Juan Carlos and Argoti, A}, doi = {10.3303/CET1545229}, journal-iso = {CHEM ENG TR}, journal = {CHEMICAL ENGINEERING TRANSACTIONS}, volume = {45}, unique-id = {2941194}, issn = {1974-9791}, year = {2015}, eissn = {2283-9216}, pages = {1369-1374}, orcid-numbers = {Pimentel, Jean/0000-0003-3359-4848; Bertók, Botond/0000-0002-1297-9792} } @article{MTMT:2931538, title = {A preliminary study of the application of the P- graph methodology for organization-based multiagent system designs: Assessment}, url = {https://m2.mtmt.hu/api/publication/2931538}, author = {Garcia Ojeda, Juan Carlos and Bertók, Botond and Friedler, Ferenc and Argoti, A and Fan, LT}, doi = {10.12700/APH.12.2.2015.2.7}, journal-iso = {ACTA POLYTECH HUNG}, journal = {ACTA POLYTECHNICA HUNGARICA}, volume = {12}, unique-id = {2931538}, issn = {1785-8860}, abstract = {At the outset, the design of an organization-based multiagent system is modeled according to the framework of Organization Model for Adaptive Complex Systems (OMACS).

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.

First, the building-evacuation routes are represented by a P-graph, which gives rise to a time-expanded process-network synthesis (PNST) problem that can be algorithmically solved by the P-graph framework. 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 validity of the proposed method is illustrated by two examples. © 2013 Elsevier Ltd.}, keywords = {Chemistry; Optimal solutions; Optimal systems; Combinatorial optimization; P-graphs; Safety engineering; Process-network synthesis; P-graph; Suboptimal solution; Minimum cost; Evacuation time; Evacuation routes; Building evacuation; Building evacuation route planning}, year = {2013}, eissn = {1873-7226}, pages = {338-347}, orcid-numbers = {Bertók, Botond/0000-0002-1297-9792} } @article{MTMT:2060145, title = {Planning Evacuation Routes with the P-graph Framework}, url = {https://m2.mtmt.hu/api/publication/2060145}, author = {Garcia Ojeda, Juan Carlos and Bertók, Botond and Friedler, Ferenc}, doi = {10.3303/CET1229256}, journal-iso = {CHEM ENG TR}, journal = {CHEMICAL ENGINEERING TRANSACTIONS}, volume = {29}, unique-id = {2060145}, issn = {1974-9791}, year = {2012}, eissn = {2283-9216}, pages = {1531-1536}, orcid-numbers = {Bertók, Botond/0000-0002-1297-9792} }
