Abstract
The object-oriented bayesian networks (OOBN) is prone to simulate for complex system, the model can be reused and the reasoning algorithm fully consider the encapsulation and hierarchy. Toward to the complexity of decision-making, distribution of knowledge and the hierarchy of the decision-making process, the method of unmanned combat air vehicle teams (UCAV) air-to-ground attack decision-making based on OOBN has been put forward. The modeling process base on OOBN has been given out. The method can establish the OOBN structure of complex system through analysis the causality between decision-making object and decision-making factors. It can be used to modeling and simulation for complex system after the probability parameter was given out. The application was been explained by a simulation example in the end.
