系统仿真就是用“活的数学模型”代替实际系统进行试验研究的过程,它是分析、研究、综合、设计各种系统的有力工具。根据性质的不同,系统可以分为两大类,一类是电气、机械、热工、水力等工程技术系统,它们通常是用微分方程描述的连续系统(Continuous systems)。另一类是社会、经 System simulation is to use “living mathematical model” instead of the actual system of experimental research process, it is to analyze, research, synthesis, design a powerful tool for a variety of systems. Depending on the nature of the system, the system can be divided into two categories, one is electrical, mechanical, thermal, hydraulic and other engineering and technical systems, which are usually described by differential equations continuous systems (Continuous systems). The other is social, economic
