TISS: a decision framework for tailing impoundment site selection

چکیده مقاله

Tailing dam is one of the most important
mining operations interface with surrounding environment
even as long as many years after ore reserve exhausted.
Therefore, appropriate design and management respect to
future limitations of environmental regulations is required.
Recently, effect of multiple criteria on tailing impoundment
site selection makes it complex as the conventional
procedures unable to answer. The systematic approach of
multi attribute decision-making helps decision-makers
select the most preferable decision and provide the basis of
a decision support system. This paper developed new
strategy based on fuzzy multi attribute group decisionmaking
methods including: technique for order preference
by similarity to ideal solution and analytical hierarchy
process in fuzzy group environment. A hypothetical case is
processed to demonstrate the strategy’s efficiency and
results are compared and ranked so that the most preferable
option is identified.
