Abstract

Power plants, due to the nature of their processes and activities and also by producing the effluents,
emitting the air pollutants and hazardous wastes, have the potential to cause negative human and
environmental consequences. Given the importance of the issue, for determining the most important
consequences of Abadan Gas Power Plant and also their impact on the human and natural
environment, as a case study, a questionnaire was developed with Delphi method. This questionnaire
was distributed within the environmentalists and experts of power plant. The human and
environmental consequences of Power Plant were analyzed by Multiple Criteria Decision-Making
methods including AHP and eigenvector technique. For this purpose, with applying of AHP method,
the hierarchical structure of the human and environmental consequences of Abadan Gas Power Plant
was constructed and then the decision making matrix was formed. The pair wise matrices were formed
separately for criteria pair wise comparisons with respect to severity and occurrence probability of
indoor and outdoor environment of power plant .With entering the data in EXPERT CHOICE
software, criteria weights were computed with applying the eigenvector method. Then the final
weights of consequences in terms of severity and occurrence probability of risk were computed. The
results from the compution of Abadan Gas Power Plant consequences indicate that in human
consequences, shallow wounds with a .105 weight and in environmental consequences, air pollution
by weighing 0.66 are the most important consequences of power plant. Finally, the most important
executable strategies and actions for mitigation of negative human and environmental consequences
were presented.
