Intelligent Processing of Flight Data Based on Petri Net

Flight data processing expert systems in being are made based on producing rule mostly.So the following problem is that knowledge representation is not easy being maturity and conduces to reasoning error easily when there are multi-layer nesting complicated logic relations among rules.In view of this shortcoming,taking identifying take-off of aircraft as an example,a method of knowledge representation and reasoning of flight data intelligent processing based on Petri Net theory is studied throughly,and an applied flight data express processing expert system is developed by using Visual C++.The processing results of many real flight data indicate that the method of knowledge representation and reasoning based on Petri Net theory can meet the need of veracity and speediness of flight data processing.So it has reference value for researching the method of parallel and intelligent flight data processing.
