Application of multi-attribute decision-making methods in SWOT analysis of mine waste management (case study: Sirjan's Golgohar iron mine, Iran)

The AHP method was used to calculate the weights of evaluation criteria and the TOPSIS method was preferred because of its capability to use both negative and positive criteria among the SWOT factors. The results of the evaluation matrix of internal and external factors showed that overall, the strengths overcame the weaknesses. However, if the opportunities are used well and correctly, threats can be overcome and weaknesses can be eliminated. Therefore, strategies based on weaknesses-opportunities (WO) are first priority. Sixteen strategies that are presented based on the SWOTs and prioritized based on TOPSIS could be useful for Sirjan's Golgohar iron ore to develop and promote its future mine waste management at the strategic level.
