TL;DR: In this paper, a multi-objective formulation of the process combines economic objectives with the LCA-based environmental objectives, based on the Hysys © model, is formulated first using a life cycle assessment toolbox.

TL;DR: An approach for the integrated consideration of both technical and valuation uncertainties during decision making supported by environmental performance information based on Life Cycle Assessment, which can be used wherever multiple criteria decision analysis is used to assist in the resolution of complex decision situations is presented.

TL;DR: In this paper, a case study for the copper cycle in the USA shows that to meet a CO2 reduction target of 60% by 2050, innovative technologies for primary processing of mined ore will play a limited role, due to their increasing impacts in the future associated with mining ever lower ore grades.

TL;DR: This approach takes account of techno-economic, environmental and social criteria, and engages explicitly with inherent network complexity in terms of the autonomous decision-making capability of individual agents within the network, who may choose not to act as economic rationalists.

TL;DR: In this article, a methodology for the ranking of power expansion alternatives given multiple objectives and uncertainty, and demonstrates this using the South African electricity supply industry, is presented, where a portfolio of preferred alternatives is then identified based on performance and confidence criteria.
