本文就M锡选矿厂该不该扩建的问题进行了可行性的逆向论证。论证用系统工程思想,从实际和理论两个方面进行能力分析;应用组合优化原理,证明1500吨/日是该选矿厂的最优规模,并获得规模报酬53.116万元(NPV)。因此否定扩建,避免了248万元的无效投资。
In this paper, M tin beneficiation plant should not be expanded the feasibility of the feasibility of the reverse argument. Demonstration using system engineering thinking, from the actual and theoretical ability to analyze two aspects; application of combinatorial optimization principle, that 1,500 tons / day is the optimal scale of the beneficiation plant, and get scale returns 531,160 yuan (NPV). Therefore denied expansion, to avoid 2.48 million yuan of invalid investment.
