Determination of the efficient locations to discharge industrial wastewater of the Sungun Copper Mine concentration plant using multi-objective approach based on Interval Data Envelopment Analysis

Currently, the environmental protection has found an important role in most countries. The effluents of the Sungun Copper Mine Concentration Plant (SCMCP) have the destructive effects. The location of farms, especially around the mine, should be performed based on technical and economical topics. In the present study, in order to the consideration of the main aims of the Mine management, a multi-objective approach is used. The effluents of SCMCP have some destructive effects on the Arasbaran forests. Thus, determination of the proper locations to discharge the wastewaters of the SCMCP is one of the important issues which should be considered. The Data Envelopment Analysis (DEA) method is an appropriate method for measuring the efficiency. The development of uncertainty in the world, indicates the importance of DEA method and its applications.
