The analysis and design class diagram are given . the sequence indication stochastic simulation algorithm based on indicator kriging is realized . the algorithm applies to discrete and continuous variable has no restrict to data distribution 系统给出了沉积相随机建模的分析类图和设计类图，实现了基于指示克里金估计的序贯指示随机模拟算法，该算法对离散数据和连续数据都适用，不要求数据的分布特征，可以较好的模拟相特征。
The key to the stochastic modeling is to build a suitable stochastic model of precipitation . in resent years , most models of precipitation process have been developed under some hypothesis or using advaced mathematical tools , but the applicability of these models is not strong 地区干旱随机模拟研究的关键是建立合适的降雨过程随机模型。目前给出的大多数降雨过程随机模型，尽管运用了较多的假定条件或高深的数学工具，但适用性不强。
The advantages of adjoint assimilation to obtain a first estimate field have been theoritically proved with provavility statistics and experimentally verified with ramdomly sampling simulation . the index to evaluate the effectiveness of adjoint assimilation , as well as the method for its calculation are given 用概率统计理论证明了伴随同化方法的初始估计的优良性，给出评估伴随同化方法效果的指标及其简单算法，并用随机模拟验证。
Members also noted that the stochastic simulations in the paper suggested that the introduction of a discount window " bid " facility of the kind considered , but not pursued , at the sub - committee s meeting of 7 may 1999 , could significantly raise reserve volatility in some circumstances . 5 委员会也获悉文件内所载的随机模拟测试显示，于1999年5月7日的委员会会议上曾经研究但并没有推行的贴现窗拆入机制在某些情况下可能会大为增加储备的波幅。
So the thesis proposes that use stochastic petri net as the expression of them in the front - end , use gillespie - gibson algorithm to perform the simulation processes in the back - end . thus not only can express biological processes intuitively , but also obtain rapid simulation speed 因此提出前台用随机petri网描述,后台采用gillespie - gibson随机模拟算法进行模拟,进而分析系统的性能,这样既保留了生物过程描述的直观性,又大大提高了模拟的速度。
Because of its discrete and stochastic charactet , it ' s hard to study deds only in terms of analytical approach . therefor the paper discusses the character of the serial production line of the production system by the method of stochastic ana1ogue and numerical simulation 本文针对制造系统中的串行生产线，用随机模拟和数字仿真试验方法进行研究，并编写了一套仿真软件进行试验，以概率统计等数学工具进行分析，得出了生产线总加工时间的一些性能特征。
This paper takes yushulin oil field , which is a super - low permeable lithologic reservoir in the peripheral part of daqing oil field , as an example and uses the geologic profiling of oil - bearing sand body to propose a set of random simulation pattern optimized arrangement which is suitable for narrow channel sand body 以大庆外围特低渗透岩性油藏? ?榆树林油田为例，通过对含油砂体的地质解剖，提出了一套适合窄条带河道砂体的随机模拟井网优化部署方法。
More and more people applied the method of stochastic simulation to heterogeneous modeling of reservoir . and each method is different from others such as basal principle , extent of complex , applied condition and so on . they all have their own applicability , advantages and disadvantages 随机模拟方法越来越多的适用于储层非均质性建模中，各种随机模拟方法在其基本原理、复杂程度和应用条件诸方面均有不同，每一种方法都有它的适用条件、优点及缺点。
