Based on sensitivity analysis and fuzzy comprehensive evaluation choosing the best concentration plant in regional mine

Because of the production process complexity and the discrepancy of every index physical meaning of the multi-mill in regional mine, it is difficulty evaluating the ore dressing plant by single index. Firstly, analyzing the sensitivity of ore dressing plant technical economic indexes, the susceptibility of technical economic benefits function have been determined. Then, according to the proportion of every index susceptibility, every factors weights have been determined.
