仿真科学的发展及形成

仿真技术在经历了发展阶段，成熟阶段和高级阶段之后，现在进入了以复杂系统仿真为研究对象的新阶段。仿真科学是在现代科学技术发展条件下形成的综合交叉科学。仿真科学包括三个基础理论：模型论、方法论和科学方法、评估理论。模型是对系统及其性质进行定量描述的最直接最清晰的科学手段之一。系统仿真应该遵循系统论确定各种方法。系统仿真领域研究的另一个重要问题是仿真系统的性能评估。性能评估包括仿真系统的可靠性、可维护性、系统功能、仿真的可信度等，其中仿真可信度是最重要的指标。

Development and Formation of Simulation Science

After development stage, mature stage and higher stage, the simulation technology enters into a new stage about simulation of complexity system. Simulation is a synthesis intercross science under the condition of development of modern science and technology. Simulation comprises three basic theories: model theory, methodology and science measure, and evaluation theory. Model is the direct and clear way to describe the system and its characteristics quantity. System simulation should follow the system theory to ensure every method. Another important hand in system simulation is the capability evaluation. Capability evaluation of system simulation includes reliability, maintainability, functional of system and reliability of simulation etc, thereinto reliability of simulation is the most important guideline.
