The Sensitivity Analysis of the Investment Decisions of the Coal Industry under the Restriction of Water Resources

Abstract:

For investment decision in the coal industry under the background of specific resources and environment in northwest, the influence of coal processing and conversion on water environment was studied, and the evaluation index system on water environmental influence was established. The TOPSIS method was used to assess the influence of air cooled generating electricity, indirect liquefaction of coal and coal-based methanol on water environment in northwest. For the evaluation results, sensitivity of the weight on the objective was discussed, and the range of various weights of the resources and environmental indicators was gained, and sensitivity analysis of sort stability about the optimal and sub-optimal program was done.
