First, we analytically develop the basic theory for conditional random fields which are represented as multi-variate stochastic processes. On this basis, this theory is applied to engineering fields, namely, methods of digital simulation and first passage solutions are discussed for conditional random fields. The significance of the method developed herein is demonstrated in various manners both from theoretical aspects and from the observation of numerical results. Furthermore, we propose methods to estimate spectra with uncertainties by means of the observed time series and develop the theoretical framework regarding the conditional random fields with stochastic spectra. Finally, to apply the results toward engineering applications, the theory and techniques of conditional simulation are applied to earthquake ground motion fields.

首先，我们在分析上开发了有条件随机场的基本理论，该理论表示为多变量随机过程。在此基础上，该理论应用于工程领域，即，讨论了数字模拟方法和第一次通道解决方案的条件随机字段。从理论方面和数值结果的观察来看，本文开发的方法的重要性都以各种方式证明。此外，我们提出的方法是通过观察到的时间序列估算不确定性的光谱，并开发有关具有随机光谱的条件随机场的理论框架。最后，为了将结果应用于工程应用，将条件模拟的理论和技术应用于地震地面运动场。
