Study Of The Coal Mine Project Investment Decision Based On The Grey System Theory

Our country engineering project investment decision-making method are constantlyin-depth study in order to adapt to the needs of the economic development in China, and it isformed a new, scientific, diversification engineering project investment decision-makingmethod through the analysis of different investment decision method and comprehensiveutilization of the effective part. Domestic and foreign scholars carried on the thoroughresearch on project investment decision methods, also has obtained many achievements, butin the situation of our country, the investment decision-making model of the project researchis still relatively backward. Therefore, the coal mine project investment decision-making isanalysed in learning and absorbing predecessors’ research results, the integrated use ofdecision model in grey system theory, by the combining of qualitative analysis andquantitative analysis, the combing theoretical analysis and empirical analysis the method. Ifyou want to make scientific coal mine project investment decision, not only investors musthave enough knowledge of the industry information, but also adopt scientific and effectivemethod to analyse the alternative information of investment project, and select the optimalsolution from many alternatives. And just the right amount of coal mine project investmentdecision can effectivly and reasonably controll the scale of investment and avoid duplicateconstruction, proper and full use of limited resources, sustainably and stably drive nationaleconomy healthy development. Therefore, the study of coal mine project investment decisionmodel can effectively guide the coal mine project investment decision makers to makereasonable coal mine project investment decision in order to maximum profit, this hasimportant theoretical and realistic significance. In terms of the coal industry, first of all, theproject investment decision of related literature at home and abroad are summarized, andanalysis of project investment decision-making method are compared, and the coal miningproject investment decision method is selected; Secondly, the grey clustering and correlationdecision-making model is established the suitable model for coal mine project investmentdecision through discussing grey clustering decision-making model and grey correlationdecision-making model, and combining with the particularity of the coal industry; Thirdly, theneeded decision indexes are determined through the expert scoring method and the indexsystem of coal mine project investment decision-making is established, and the optimalscheme selection is determined from collected the information of five merger and acquisition coal mine through the application of the grey clustering and correlation decision-makingmodel. Finally, grey clustering and correlation decision-making model is effective andfeasible in the coal mine project through validity check.
