摘要/Abstract

摘要： 提出一种基于Credal网络的港口生产安全评价方法。建立了基于Credal网络的安全评价模型,并融合多专家的各种不确定性概率知识进行推理。然后,结合BNT工具箱,给出了Credal网络模型的双向推理算法实现,在诸多不精确局部概率条件下,进行前向的故障预测和后向的诊断分析,并通过对码头前沿机损的安全评价实例说明该评价方法的合理性和有效性。

Abstract: A new safety assessment approach for harbor production based on Credal network has been proposed.A safety assessment model based on Credal network has been established,which can fuse many experts’uncertain probability knowledge to infer.Then,integrating with BNT toolbox,it gives bidirectional inference algorithm realization about Credal network,performing the forward fault prediction and backward diagnosis analysis on the condition of many uncertain local probability.It provides an example on safety assessment for machinery breakdown in dock apron to illustrate the rationality and validity of Credal network approach.
