Abstract: The requirement modeling process of weapon system-of-systems is full of uncertainty.On the other hand，the quality of weapon system-of-systems requirement modeling effects validity and reliability of requirement models directly，and further，the weapon system-of-systems constructing.This paper develops a quality evaluation method of weapon system-of-systems requirement modeling based on Bayesian Network（BN） for clearly understanding of its essence and ensuring consistency and reliability in modeling process.This method well uses expert knowledge and statistic data，and deals with the uncertainty problems in weapon system-of-systems requirement modeling.Making use of reasoning method in BN，it also can get the key influencing element combination.A simulation example shows that the method has good expansibility and feasibility.
