系统工程既然是运用工程方法对目标和步骤进行优化设计、优化抉择、优化控制、优化管理、以达到优化效益的一门组织管理技术,不仅涉及较为广泛的知识,而且也同数学密不可分.所谓最优化,从数学上讲,是个极值问题-最大值或最小值.如产值最大,效率最高,利润最多,成本最低,费用最少,时间最省,距离最短,速度最快等等.因此,系统工程讲究数量分析,采用一定的数学语言和数学工具,建立数学模型,
Since system engineering is an organization management technology that uses engineering methods to optimize the design of goals and steps, optimize selection, optimize control, and optimize management to achieve optimal benefits, it involves not only a wide range of knowledge, but also is inseparable from mathematics. Optimization, mathematically speaking, is an extreme problem - the maximum or minimum value. If the output value is the largest, the most efficient, the most profitable, the lowest cost, the least cost, the least time, the shortest distance, the fastest, and so on. Therefore, System engineering pays attention to quantitative analysis, uses certain mathematical language and mathematical tools, and establishes mathematical models.
