Mined land use selection using a modified version of TOPSIS method,that can handle uncertainty, by accepting inputs as D numbers

摘要

Mined land use management and mine reclamation are considered an undeniable component of modern mining plan.Multi criteria decision making methods are one of the tools that have been widely used in determining the appropriate alternative among all scenarios of land use,along with land suitability analysis.But when applying a multi criteria decision making method,the criteria designed to be used in the study are mainly cost oriented,or only technical aspects of the problem are considered.In this study it's tried to develop a new approach for after mining land use selection,by combining the concept of D numbers introduced by Deng,with the TOPSIS method idea (shortest geometric distance from the positive ideal solution and the longest geometric distance from the negative ideal solution).Criteria used in the method are designed considering sustainable developments triple bottom line.Finally a case study with real world data from Sarcheshmeh copper mine of Iran is provided to illustrate the model use.The results show that the alternative museum or exhibition of mining innovations is the most appropriate one among the others,according to the similarity index.
