The energy supply-chain model contains agricultural, pre-processing, processing, and distribution layers. An integrated model, previously developed by the authors, for regional biomass energy network optimisation is used as a basis, and now extended for simultaneous assessment of the supply-chain performance based on LCA (Life cycle assessment). Several total FPs are introduced for " cradle" to " grave" evaluation, which, besides direct, comprises also indirect effects caused by products' substitutions. In the MCO approach, the annual profit is maximised against each FP generating different sets of Pareto optimal solutions, one for each FP. With this approach the aggregation of different environmental and/or social pressures is thus avoided. The results indicate that total FPs enable the obtaining of more realistic solutions, than in those cases when only direct FPs are considered. More profitable and less environmentally harmful solutions can be gained with significant reduction in total carbon and total energy FPs. © 2012 Elsevier Ltd.}, keywords = {Optimization; life cycle; BIOMASS; Profitability; Energy resources; Total organic carbon; Regional Energy Supply Chains; Footprints; Bio-mass energy; LCA; Energy supply chains; Optimisations; biomass power; Supply chains; Ecological footprint; electricity generation; electricity supply; Total footprints; Multi-criteria optimisation; Biomass energy generation}, year = {2012}, eissn = {1873-6785}, pages = {135-145} } @article{MTMT:1674660, title = {Synthesis of regional networks for the supply of energy and bioproducts}, url = {https://m2.mtmt.hu/api/publication/1674660}, author = {Čuček, L and Lam, H L and Klemeš, Jiri Jaromir and Varbanov, Petar and Kravanja, Z}, doi = {10.1007/s10098-010-0312-6}, journal-iso = {CLEAN TECHNOL ENVIRON POLICY}, journal = {CLEAN TECHNOLOGIES AND ENVIRONMENTAL POLICY}, volume = {12}, unique-id = {1674660}, issn = {1618-954X}, abstract = {This article presents a method for the synthesis of regional renewable energy supply chains, based on Mixed-Integer Linear Programming (MILP). This method addresses the challenges presented by biomass resources. The main challenges are the distributive and varied availabilities regarding both location and time. This work also aims to maximise the economically viable utilisation of resources, accounting for the competition between energy and food production. A four-layer supply chain superstructure has been developed, which includes the harvesting, preparation, core processing and distribution of products. This considered system's boundaries involve a region, which is then divided into zones for optimising conversion operations and transportation flows. An MILP model has been formulated with profit maximisation as the optimisation criterion. The environmental impact is evaluated by the carbon footprint. The sensitivity of the optimal solutions is analysed for different regions' sizes, transportation costs, pre-processing alternatives and the co-production of food and energy. © Springer-Verlag 2010.
