一些信息和知识通常用人类语言表示，如“大约100公里”，“大约39°C”，“大约80公斤”，“低速”，“中年”和“大尺寸”。我们如何理解它们？也许有些人认为它们是主观概率或模糊概念。然而，大量的调查表明，这些不精确的量既不像随机性，也不像模糊性。这一事实提供了发明另一种数学工具的动机，即不确定性理论。
Some information and knowledge are usually represented by human language like “about 100km”, “approximately 39°C”, “roughly 80kg”, “low speed”, “middle age”, and “big size”. How do we understand them? Perhaps some people think that they are subjective probability or they are fuzzy concepts. However, a lot of surveys showed that those imprecise quantities behave neither like randomness nor like fuzziness. This fact provides a motivation to invent another mathematical tool, namely uncertainty theory.
