摘要
提出了异于文献中的随机投入产出控制模型,即对于随机最终需求,如何由控制模型确定出各部门的最小产出量.在最终需求为服从指数分布的随机变量的情形下,利用统计学中独立随机变量和的分布理论,基于模型中参数间的不同关系,导出了给定可靠性下产出量所满足的控制方程,给出了数字例.
The control model of the stochastic input-output is proposed, which is different from that of references. It is how to obtain the minimum outputs by using the control model with stochastic final demand. Suppose that final demand is a random variable with exponential distribution. By using the distribution theory of the sum of the independent random variables, control equations of output based on given reliability is derived, and also an example is given.
