什么是系统理论?让我们先从两个事例说起; 一九七六年,苏联曾有一名驾驶员驾驶一架当时颇负先进盛名的米格25飞机逃到日本。经日美联合拆件检查,发现飞机上有些零部件从单个来看并不是最先进的,甚至比美国的落后得多,但飞机的爬高能力和飞行速度却是当时世界第一流的。这是由于制造者考虑的主要是整个系统的性能,而不斤斤于某一零 Let us begin with two examples. In 1976, a driver from the Soviet Union flew to Japan with a MiG-25 aircraft that was rather prestigious at that time. After unpacking the Japanese-US inspection, it was found that some of the components on the plane were not the most advanced from a single point of view and even far behind the United States. However, the ability to climb and the flight speed of the aircraft were the highest in the world at that time. This is due to the fact that manufacturers are primarily concerned with the performance of the entire system, rather than focusing on a single zero
