RESEARCH ON COAL MINE PROJECT INVESTMENT DECISIONS BASED ON GREY CLUSTERING - CORRELATION DECISION MODEL

The research builds grey clustering - correlation decision model to study on project investment decisions by combining the grey clustering decision model and the grey correlation decision model. The model can comprehensive evaluate the programs and choose the optimal program. At the same time, it can reduce artificial subjective factors influencing on the result of investment decisions in a certain extent. The empirical data are used in the proposed analysis on coal mining project investment decisions. According to empirical analysis and validity validation of the grey clustering correlation decision model, we found the evaluation result is stable and the method is feasible and effective. By the reseach, it provides theoretical basis for making the project investment decisions, and provides practical basis for investors of coal mine project making scientific investment decision by evaluating the projects comprehensive and choosing the optimal project.
