The random errors of main factors in flood regulation process are identified; and combining flood forecast, the randomnesses of main parameters such as initial reservoir level, inflow flood, outflow flood, etc., are analyzed. By using the first order second moment method and theoretic distribution, the random distributions of parameters are described then the routing process of a certain preflood limit water level is random, which can well reflect the random preflood influences in actual regulation.

Firstly, an empirical approximation model of stochastic programming is obtained by replacing the probability measure of original program with empirical probability measure. Sequentially, the constrained stochastic programming is transformed into an equivalent unconstrained stochastic programming. Finally, using the epi-convergence theory, the almost everywhere upper semiconvergence of optimal solution set of empirical approximations for stochastic programming is obtained.

针对现有的资源总量随机求和中存在的资源总量曲线形态有时呈偏态分布的问题，提出了对其随机抽样方法的改进方案，即把随机抽样入口由原来定义在(0，1)区间上改为定义在(0，ki)区间上(ki为第i个局部地质单元的石油资源量保险系数)，利用(0，ki)区间上均匀分布的随机数对风险分析后的资源总量分布函数进行随机抽样。

Based on the idea and technical in the references[16],[17]and[26]as well as the theories of martingale,Brownian motion and stochastical orders,the expectation of present value of annuities with controlled random interests is obtained,and the upper bounds of present value function of discrete stochastic annuities with random interests in sense of convex order are derived,and the numerical characteristics of upper bounds are also obtained,furthermore,the expec

Although similar in results at times, generating random values is different from turbulence. Randomizing means that values are randomly chosen from a range of values at every frame of the simulation.

尽管紊乱和随机两种设置有时能获得同样的结果，但是生成随机值和紊乱值还是有差异的，区别在于：随机化意味着在模拟过程在每帧之内，都是在一个范围内随机选取一个值并执行。
