多分量动态系统的快速仿真
Fast Simulation of Multicomponent Dynamic Systems
摘要：
计算机模拟要研究多组分动力学系统的行为，必须速度快才有帮助。本文讨论了建模的概念和算法技术，用于创建这样的快速模拟。从计量经济学建模到通信到材料科学的模拟的具体例子被用来说明这些技术和概念。讨论的算法和建模方法包括事件驱动处理、"预期“数据结构和”惰性“评估、泊松分配器、通过谨慎推进和同步松弛的并行处理。本文给出的例子，这些技术和模型是如何在无线和有线网络的容量管理方法的效率进行评估，在磁化，晶体结构和沉积物的形成在材料科学的研究，在经济学的竞争研究。
英文摘要：
A computer simulation has to be fast to be helpful, if it is employed to study the behavior of a multicomponent dynamic system. This paper discusses modeling concepts and algorithmic techniques useful for creating such fast simulations. Concrete examples of simulations that range from econometric modeling to communications to material science are used to illustrate these techniques and concepts. The algorithmic and modeling methods discussed include event-driven processing, ``anticipating'' data structures, and ``lazy'' evaluation, Poisson dispenser, parallel processing by cautious advancements and by synchronous relaxations. The paper gives examples of how these techniques and models are employed in assessing efficiency of capacity management methods in wireless and wired networks, in studies of magnetization, crystalline structure, and sediment formation in material science, in studies of competition in economics.
