不确定性

Transport system is a random nature, ambiguity and uncertainty of complex systems, the establishment of mathematical models very difficult and sometimes impossible to use existing mathematical methods described.

交通系统是一个具有随机性、模糊性和不确定性的复杂系统，建立数学模型非常困难，有时甚至无法用现有的数学方法加以描述。

in information theory, entropy is a measure of the uncertainty associated with a random variable.

信息熵是信息论中用于度量随机变量的不确定性。

You can give up control of your reality by thinking randomness and uncertainty, but you can never give up responsibility.

你可以通过聚焦随机性和不确定性来放弃对你自己实相的控制，但是你无论如何也逃避不了你该承担的责任。

Referring to the construct of the common experts system, the frame and function of our system was determined to extend the OPS83 ratiocinative method with converse ratiocinative method, and the ratiocinative mechanism based on target-driver controlling was realized. In accordance with the complexity, uncertainty and confusion of chip forming and chip-breaking process, We suppose imprecise ratiocinative mechanism on the basis of confusion mathematics theory, and found prediction system of the chip forming and chipbreaking for the first time.
