Abstract:

Facing on the continual changing of future combat conditions, the designer of weaponry system of systems (WSoS) needs to identify and recognize the capability set which is important to significant improvement in SoS effectiveness under limited resources and restricted technology. Using an interval number with confidence to measure WSoS capability and using beta distribution to picture the prior distribution of WSoS performance index are proposed. A WSoS capability weightiness degree analyzing model is constructed based on Bayesian network theory and WSoS capability index breakdown structure, and a calculating method of capability weightiness degree by Bayesian inference is proposed. The result indicates that the proposed model is an effective analysis tool for WSoS capability weightiness degree.
