小行星9523111 研究目的是通过在并行处理器上进行仿真实验，探讨如何提高仿真效率。在研究中设想的并行仿真方法涉及到分割的时间范围分配处理器来模拟整个系统的一小部分的总时间范围。这相当于只将总时间段的一部分分配给处理器。在并行处理机上应用时间分段模拟随机系统的一个主要困难是找到有效的方法来生成底层系统的有效样本路径。 当模拟开始时，除了第一个处理器或时间段之外，所有处理器或时间段上的模拟的初始条件都是未知的，这一事实使这一点变得复杂。在这项研究中的新方法是有关确定的适用范围和并行仿真方法的效率。这项研究将确定并行仿真方法何时可以用于有效地分析复杂系统。 仿真是研究和分析复杂动态系统的重要工具。它的应用领域很广，包括工程、经济和社会系统。 使用模拟的一个常见批评是在生成有意义的数据之前需要大量的计算工作。并行仿真方法，在这项研究中，是一个走向加快计算机上的仿真过程。如果成功，该技术将立即应用并纳入商业模拟软件。大规模应用将大大节省时间和金钱，并缩短进行模拟研究所需的时间。

9523111 Andradottir The research objective is to investigate how the efficiency of simulation can be improved by conducting the simulation experiment on parallel processors. The parallel simulation approach envisioned in the research involves segmenting the time horizon allocating processor to simulate the entire system over a fraction of the total time horizon. This is equivalent to allocating only a portion of the total time segments to a processor. A major difficulty in applying time segmentation to simulate stochastic systems on parallel a processor is finding efficient ways of generating a valid sample path of the underlying system. This is complicated by the fact that the initial conditions for the simulation on all but the first processor or time segment are unknown when the simulation is started. The new approach in this research is concerned with determining both the scope of applicability and the efficiency of a parallel simulation approach. The investigation will determine when parallel simulation approachs can be used to efficiently analyze complex systems. Simulation is a key tool for studying and analyzing complex and dynamic systems. Its application domain is large and includes engineering, economic, and social systems. One common criticism in the use of simulation is the amount of computational effort required before meaningful data can be generated. The parallel simulation approach, investigated in this research, is a move towards speeding up the simulation process on computers. If successful, the technique will see immediate application and incorporation into commercial simulation software. Large scale application will produce significant savings in time and money and shorten the length of time required to perform a simulation study.
