| 摘 要： | 针对最终需求为正态随机变量的投入产出模型,建立了一个时序模型来估计最终需求的期望与方差,并由此给出了总产出在一定置信度下的取值空间.这样就使得随机投入产出模型在决策时可具体操作.

| Abstract: | This paper discusses the input-output model when the final demand of every sector is a normal random variable.A time series model is constructed to estimate the expectation and variance of every final demand.Then the range of the total output for a certain confidence level is presented.Therefore the random input-output model can be available when making decision. |

| Keywords: | final demand total output time series |
