Firstly , the random mathematics model of the guidance system is set up , with the random factors such as the seeker , the guidance law , the automatic pilot , the dynamics , the relative kinematics taken into account 首先进行反辐射无人机系统的随机建模，包括导引头、制导律、自动驾驶仪，机体动力学，相对运动学等，建模时必须考虑随机因素的影响。
In order to reduce the economic losses due to water shortage , it is necessary to evaluate the risk of water shortage , and manage the risk by a series of structural and non - structural measures based on the evaluation 受降雨、径流及其它各种随机因素的影响，供水和需水都会不同程度地存在许多不确定性因素，因此，我国大多数地区出现水资源短缺风险是必然的。
As information asymmetry and many random factors exist in the process of production and delivery in supply chain , it is important for supply chain how to signal responding capacity through leadtime - contingent pricing policy 摘要由于生产和物流过程中存在众多随机因素及信息不对称，如何通过交货期相关定价有效地显示其市场响应能力，对于供应链企业竞争来说是极其关键的。
The forth , from the result of regression analysis , the firing accuracy of projectile effected by random factors is studied , and the suggestion that the test of projectile ' s firing accuracy can be replaced by measuring some parameters is put forward 第四，由回归分析结果，分析了随机因素对弹丸射击精度的影响，并提出弹丸的射击精度试验可由某些参数的测量来代替的设想。
This dissertation focuses on firing accuracy of projectile effected by random factors . the main contents are included as follow : the first , a model of launching dynamics of projectile is set up , and the numerical calculation software is programmed 本文围绕随机因素对弹丸射击精度影响展开研究，主要包括四个方面的内容：第一，建立了较为完善弹丸发射动力学模型，并编制了相应的计算分析软件。
From the points of view for practical uses , the thesis uses the furnace of high - speed - wire factory of tangshan steel company as object , studies the casual process of nonlinear and distributed parameter with big inertia , pure lag and disturbed by casual factors 本文从工程实际出发，以唐山钢铁公司高线厂加热炉为研究对象，对受随机因素干扰的、具有大惯性、纯滞后的非线性分布参量的随即过程进行了研究。
In view of practical use , taking the regenerative furnace of the first plant of high - speed - wire factory of tangshan steel company as object , the thesis studies the casual process of nonlinear and distributed parameter with big inertia , pure lag and casual disturbance 本文从实际出发，以唐山钢铁集团有限公司高线厂一车间蓄热室加热炉为研究对象，对受随机因素干扰的、具有大惯性、纯滞后的非线性分布参量的随机过程进行了研究。
Collective risk theory as a part of insurance business , the compound poisson risk theory is one of the principal models in the lengthy history of risk theory , many classical results have been got in many monograph , many scientists have generalized the classical compound poisson risk model in many ways 自经典的风险模型提出后，研究者对其作了各种推广，大部分的推广模型中，保费的收入过程是时间的线性函数，没有体现出随机因素对保费收入的影响。
Under this background , we have to design new simulation software for cdma data service and gota system . the dissertation starts with the research of random factors in wireless network , electromagnetic wave spread , traffic mode and monte carl method , and then designs an integrated cdma simulation arithmetic , later tests it at matlab , balances it with existing software and practice data , finally investigates the theory and traffic mode of gota , designs gota simulation arithmetic 本论文首先通过对无线网络中的随机因素、电磁波的传播、话务模型以及montecarl计算机仿真方法的研究,在中兴cdma20001x系统原理的基础上设计出了一套完整的适应于cdma20001x的仿真系统算法,并且在用matlab代码实现后,进行了与同类软件的对比测试和与实际数据的对比测试工作。
