【摘要】 针对当求解大规模Web服务组合可靠性分析的问题时,建立的广义随机网格模型往往会遇到评估过程过于复杂的状况,造成评估分析结果不准确的问题,提出一种基于随机网格简化的Web可靠性分析方法。通过简化Web搜索过程中的网格,通过模型的公平分解,完成随机网格的基本结构的化简,保证可靠性分析的准确性。实验结果表明,在加入了网格简化方法后的Web状态空间复杂程度大幅降低,可靠性分析准确性提高效果明显,证明所提出的设计方法具有一定的优势。更多还原

【Abstract】 For when solving large-scale Web service reliability analysis the problem of combination,the establishment of generalized stochastic grid models often will meet the evaluation process is too complicated situation,making assessment analysis results are inaccurate.Is proposed based on a random mesh simplification Web of reliability analysis method.By simplifying the Web search process of the grid.By the model’s fair decomposition,complete random grid of the fundamental structure of the reduction,guarantee the accuracy of the reliability analysis.The experimental results show that in the join mesh simplification method after Web state space complexity has greatly decreased,improve reliability analysis accuracy obvious effect,prove that the proposed method has a certain advantages更多还原
