“…Technological change that enhances energy efficiency is stimulated by changes in the price energy, including carbon taxes. Inexact Dynamic Optimization Model is first proposed by Huang and has been applied to practical engineering projects, such as agricultural/timbering activities in Mackenzie Basin, Canada (Huang et al, 1996), energy system management and GHGemission control in the Municipality of Beijing ), greenhouse-gas emission management and sustainable renewable energy development under uncertainty , municipal solid waste (MSW) management under uncertainty . System Dynamics Approach is also effective to reduce emissions of carbon dioxide in engineering projects.…”

“…Results suggest that potential expansion of commercial agriculture would increase soil erosion, and spruce production would fall short of its target. Additional activities in multiobjective programming (Huang et al, 1996(Huang et al, , 1997) also focus on potential expansion of agriculture.…”

ABSTRACT. Global climate change, also known as global warming, is one of the most challenging elements of global environmental change. If atmospheric concentrations of carbon dioxide and other "greenhouse gases" continue to increase, global mean air temperatures are expected to rise 1.5˚ to 4.5˚C within the next several decades. High-latitude regions are projected to experience above-average increases. What effects would such a warming have in the Canadian Arctic? In a recently completed study of the Mackenzie Basin in northwestern Canada, regional stakeholders provided their responses to the "what if?" scenario of climate change in their region. This scenario includes more frequent landslides due to permafrost thaw, lower minimum annual river and lake levels, more forest fires, and lower yield from softwoods. These impacts could offset potential benefits from a longer growing and ice-free season. Regional stakeholders, including provincial and territorial governments, aboriginal organizations, and the private sector, felt confident about their abilities to adapt, so long as climate change would be predictable and gradual. Some potential impacts, however, could be very significant for renewable resources and aboriginal communities, and some stakeholders spoke of intervention into national and international policy arenas to raise awareness outside of the Mackenzie Basin.Key words: climate change, Mackenzie Basin, climate impacts, integrated assessment, stakeholders RÉSUMÉ. Le changement climatique mondial, qu'on appelle aussi «réchauffement de la planète», est l'un des aspects du changement de l'environnement planétaire qui présente le plus de défis. Si les concentrations atmosphériques en gaz carbonique et autres «gaz à effet de serre» continuent d'augmenter, les températures moyennes globales de l'air devraient s'élever de 1,5 à 4,5˚C au cours des prochaines décennies. Quelles seront les répercussions d'un tel réchauffement sur l'Arctique canadien? Dans une étude récemment achevée, portant sur le bassin du Mackenzie situé dans le nord-ouest du Canada, les parties concernées ont fourni leurs réponses au scénario d'anticipation du changement climatique dans leur région. Ce scénario comprend une augmentation de la fréquence des glissements de terrain dus au dégel du pergélisol, une baisse des niveaux minimaux de l'année des lacs et cours d'eau, une augmentation des incendies de forêt, et une baisse du rendement des résineux. Ces retombées pourraient neutraliser les bénéfices potentiels d'une plus longue saison de croissance et d'inter-glaciel. Les intervenants régionaux, y compris les gouvernements provinciaux et territoriaux, les organismes autochtones et le secteur privé, se sont dit confiants quant à leurs capacités d'adaptation, pour autant que le changement climatique soit prévisible et graduel. Certaines répercussions potentielles pourraient cependant avoir une importance majeure pour les ressources renouvelables et les collectivités autochtones. Des intervenants souhaitaient même une intervention au niveau ...

“…Nonetheless, they also claimed that process control consists of the anticipatory consideration and the reaction to unexpected occurrences, while long-term planning is usually a prerequisite for detailed scheduling and process control. How to take process control and scheduling into account during operation planning have become a rapidly growing area of research and a subject of interest to academicians and practitioners alike (Huang et al, 1996;Yin et al, 1999).…”

ABSTRACT. An ideal combination of process control and operation planning can reduce system cost and maximize economic and environmental benefits. This research proposed an integrated simulation-based process control and operation planning (IS-PCOP) system by using neural networks, genetic algorithm, multistage principle, and Monte Carlo simulation. It could well link process control and operation planning by simultaneously adopting different time-scales in computation. The hourly process control strategy forwarded the results to the operation planning module where long-term arrangements could be further evaluated. The use of ANN modeling also played a key role in predicting the nonlinear behavior of complex processes. In addition, Monte Carlo simulation yielded a better insight on uncertainties, which may arise from a number of different sources. A case study on marine wastewater management was carried out to demonstrate the efficacy of the proposed approach. Six different treatment standards (i.e., 5, 10, 15, 20, 25, and 30 μg L −1 ) were examined over a 20-day period and the 20 μg L −1 standard appeared to be the most economic option with a mean net cost of $18 per day. As compared to the traditional operation planning without process control, the integrated approach achieved more economically competitive results. By addressing the uncertainties and expressing the results in probability distributions, the decision makers would have more confidence in making decisions on both short-and long-term operations. It was concluded that the combination of process control and operation planning could help meet the economic objectives and ensure timely completion of the tasks.
