Abstract:

In order to ensure that the complex simulation system can meet the credibility requirements, the credibility of each simulation sub-system should be determined at the beginning of the construction of the complex simulation system to shorten the development cycle. Therefore, a complex simulation system intelligent credibility allocation method is proposed, which can obtain the credibility allocation results of each simulation sub-system under the condition of the known whole credibility of the complex simulation system. According to the composition and structure of the complex simulation system, the credibility allocation model of the complex simulation system is proposed based on the multi-layer pairwise Markov random field (ML-PMRF). Based on the maximum a posteriori inference and the discrete glowworm swarm optimization, an intelligent inference method for ML-PMRF is proposed. The effectiveness and rationality of the proposed method are verified by practical examples and comparative experiments.

Key words: complex simulation system, credibility allocation, multi-layer pairwise markov random field (ML-PMRF), intelligence inference
