一、目的随着计算机技术的发展,用数字计算机模拟系统的运行过程考察各系统参数对系统性能的影响,从而选择最合适的系统参数以求得最佳效果,已成为研究系统的最有力的工具。它已广泛应用于工业工程,航天技术,经营管理以及社会科学等领域。对于简单的系统,有时可以用数字分析的方法进行比较准确的计算,但如系统较为复杂,随机因素较多,分析计算 First, the purpose With the development of computer technology, using digital computer simulation system to examine the operation of the system parameters of the system performance impact, so as to select the most appropriate system parameters in order to get the best results, has become the most powerful research system tool. It has been widely used in industrial engineering, aerospace technology, management and social sciences and other fields. For simple systems, numerical analysis can sometimes be more accurate method of calculation, but if the system is more complex, more random factors, analysis and calculation
