投入产出分析的不确定性模型及其预测

Uncertain Models and Prediction on Input-output Analysis

本文在不确定性系统理论、不确定性数学的基础上,对投入产出分析中的部门之间的流量xij、总产值Xi、最终产品Yi、直接消耗系数矩阵A、完全消耗系数矩阵B给出了不确定性表达式,利用不确定性数学对投入产出模型进行了拓广,并通过实例说明了它的应用。

This paper,based on the uncertain system theory and uncertain mathematics,gives the uncertain expression formula such as interdepartmental flow Xij,total output value Xi,end product Yi,predicting structural matrix A=(aij)n and complete structural matrix B=(bij)n in the inputoutput analysis. Besides,it expands the application the inputoutput model by means of uncertan mathematics and introduces its application value through examples.
