This research aims at presenting landscape management planning methods to help stakeholders select forest ecosystem plans that may address concerns with wildfire risk and the environmental impacts of clearcuts. Specifically, we develop mixed integer programming models for spatial optimization incorporate a resistance index as well constraints on size clearcut openings. The former is used enforc...

Concerns over air and water quality to date have been related primarily to nutrient issues, specificall...

Nowadays, researches pay more attention to environmental concerns consisted of various communities. This study proposes a multi-echelon, multi-period closed-loop supply chain (CLSC). A comprehensive model considers the selection of selection of technology and environmental effects. The supply chain is under a build-to-order (BTO) environment. So, there is not a final product inventory. Also, th...

We consider a Unit Commitment Problem (UCP) addressing not only the economic objective of minimizing the total production costs—as is done in the standard UCP—but also addressing environmental concerns. Our approach utilizes a multi-objective formulation and includes in the objective function a criterion to minimize the emission of pollutants. Environmental concerns are having a significant imp...

The use of rare earth elements in various technologies continues to grow despite some alternatives being found for particular uses. Given a history of ecological concerns about pollution from rare earth mines, particularly in China, there are growing social and environmental concerns about the growth of the mining and mineral processing in this sector. This is best exemplified by the recent soc...
