什么是系统分析?它与系统工程有什么关系?

答案

参考答案:

系统分析是运用建模及预测、优化、仿真、评价等技术对系统各有关方面进行定性与定量相结合的分析,为选择最优或满意的系统方案提供决策依据的分析研究过程。

狭义上讲,系统分析的重要基础是霍尔三维结构中逻辑维的基本内容,并与切克兰德方法论等有相通之处;广义上讲,有时把系统分析作为系统工程的同义语使用。

   42 was it that these men,who had lived in a breeding place of crime,had such a 43 good record? The researchers were continually told,“Well,there was a teacher…”
