Appropriate maintenance technologies that facilitate model consistency in distributed simulation systems are relevant but generally *** resolve this problem,we analyze the main factors that cause model *** analysis methods used for traditional distributed simulations are mostly empirical and qualitative,and disregard the dynamic characteristics of factor evolution in model operational ***,distributed simulation applications(DSAs)are rapidly evolving in terms of large-scale,distributed,service-oriented,compositional,and dynamic *** developments present difficulty in the use of traditional analysis methods in DSAs,for the analysis of factorial effects on simulation *** solve these problems,we construct a dynamic evolution mechanism of model consistency,called the connected model hyper-digraph(CMH).CMH is developed using formal methods that accurately specify the evolutional processes and activities of models(i.e.,self-evolution,interoperability,compositionality,and authenticity).We also develop an algorithm of model consistency evolution(AMCE)based on CMH to quantitatively and dynamically evaluate influencing *** results demonstrate that non-combination(33.7%on average)is the most influential factor,non-single-directed understanding(26.6%)is the second most influential,and non-double-directed understanding(5.0%)is the least *** previous analysis methods,AMCE provides good feasibility and *** research can serve as guidance for designers of consistency maintenance technologies toward achieving a high level of consistency in future DSAs.
