Grey Input-output Analysis for Fixed Assets

It is hard to get precise input/output data when decision-makers analyze and control the complex economic system by using input-output analysis for fixed assets. However, the appropriate tools and statistic approaches let the managers easily obtain some intervals covering the precise data. By using grey system theory, we propose grey input-output analysis for fixed assets and obtain formulas for grey coefficients and grey models. These grey models and grey coefficients are computable and they make the decision-makers control over the complex economy system under uncertain situations with poor information. At last, the modified case verifies the effectiveness of our method.
