Evaluation of Equipment Contribution Rate to System-of-systems Based on Hybrid Parameter Evidential Network

An evaluation method of equipment contribution rate to system-of-systems based on hybrid parameter evidential network is proposed for the complicated correlation between the capability of equipment system-of-systems and the uncertainty of evaluating information. An evidential network structure model for evaluation of equipment contribution rate to system-of-systems is constructed based on the correlation between the capabilities of the same level. The requirement satisfactory degree evaluation methods for evaluating the capabilities of the same level based on conditional belief parameter model and the cross-level based on belief rule parameter model are proposed, respectively, and an evaluation model of equipment contribution rate to system-of-systems is established according to the utility function. An anti-aircraft carrier equipment system-of-systems is modeled and analyzed.The results show that the proposed method can reflect the emergence of the overall capability of equipment system-of-systems, and can evaluate the equipment contribution rate to system-of-systems comprehensively and objectively.
