Application of Cloud Theory in Reliability Assessment of Combat Aircraft
Yue Li · Jisuanji fangzhen · 2005
Traditional reliability evaluation of combat aircraft usually adopts qualitative methods, and for precise quantitative assessment, there is no effective way up to now. Cloud theory has been proved to be an excellent mathematical tool for dealing with uncertain and vague description of objects, and it can realize the transforms between qualitative concepts and their quantitative expression. Based on the cloud theory, the model of system performance model and the cloud model of the reliability assessment are proposed. A new way for reliability assessment of combat aircraft is given and it can solve the transition problem between qualitative and quantitative in reliability assessment. The result of assessment can reflect the distribution of data and mode of our thinking while keeping the qualitative boundaries. Finally, this paper gives the reliability assessment of a combat aircraft using the formulae.
