To study the chaotic degree of system function state change in the system fault evolution process, the concept of entropy is introduced, and the entropy of the system fault evolution process (evolution entropy for short) is proposed. Evolution entropy is the chaotic degree of the system function state at a certain time in the evolution process. It is a measure of change in the chaotic degree of the system function state when the system evolution develops from one moment to another. It is numerically equal to the event fault probability distribution entropy at that moment (referred to as distribution entropy). The research shows that the evolution entropy can only be obtained from the event fault probability distribution at a certain moment and has a certain range of value domains. The logical relationship of events in the evolution process directly impacts the change in evolution entropy. The OR logic reduces the evolution entropy to less than the distribution entropy of any participating event. Moreover, the AND logic increases the evolution entropy to greater than the distribution entropy of any participating event. With the increase in transfer time, the effect of AND logic and OR logic on the increase and decrease in evolution entropy reduces, respectively. Finally, the determination process of evolution entropy is exhibited by an example, summarizing the problems existing in the current research and putting forward the following research direction.
