基于随机理论的汇流计算方法研究

Research on Stochastic Linear Flow Concentration System

把随机微分方程理论引入到汇流计算中,以线性水库汇流系统为例,建立了一个计算汇流过程的随机微分方程模型。该模型将输入过程和模型参数均视为随机变量,采用建立矩方程的方法求解相应的随机微分方程,得到一个简单的计算汇流系统出流过程的统计矩公式。研究表明,随机微分方程理论应用到汇流系统是一种值得深入研究的方法。

Take the linear reservoir cable-tap system as the example, we applied the stochastic differential equation theory to flow collection calculation and established a stochastic differential equation model. In the model the input process and model parameters are considered to be stochastic, if we used the matrix equations to solve the stochastic differential equation. A simple rectangular formula was abtained to calculate the run off process of cable-tap system. The research results showed that it is a method which worth studying for applying the stochastic differential equation theory to the cable-tap system.
