基于熵权与模糊物元模型的油库安全评估指标体系建设

Construction of Oil Depot Safety Evaluation Index System Based on Entropy Weight and Fuzzy Matter Element Model

将该指标与基于信息熵的综合评判体系中的各因子权重进行融合,通过权重的求解公式及改进后的模糊物元模型,对石油库的安全水平进行判定。实证研究表明:采用基于熵的方法,并与模糊物元法进行综合评价,削弱加权的极端效应,实现多源数据的定性与定量的有效融合。基于该方法,降低了人工干扰,提高了评估效果,并与实测数据进行了比较。实验结果表明,该评估方法具有较好的实用性。

The index is fused with the weights of each factor in the comprehensive evaluation system based on information entropy,and the safety level of the oil reservoir is judged by the weight solving formula and the improved fuzzy matter element model.The empirical results show that the entropy-based method and the fuzzy matter-element method are used for comprehensive evaluation to weaken the extreme effect of weighting and realize the effective integration of qualitative and quantitative data from multiple sources.Based on this method,the artificial interference is reduced,the evaluation effect is improved,and the measured data are compared.Experimental results show that the evaluation method has good practicability.
