摘要
根据矿山安全评价所存在的模糊性和随机性的特点,在建立多级模糊综合评价的指标体系的基础上,借用信息论中熵的概念计算客观权重的方法,运用模糊数学理论,建立二级模糊综合评价模型,提高了矿山安全现状评价的客观性和科学性,具有一定的工程实际应用价值.
In view of the existing fuzziness and randomness in the comprehensive safety evaluation for mines, a two--level fuzzy assessment model for the evaluation of petrochemical production units is established by using the theory of fuzzy mathematics. The calculation method of objective index weight through the concept of entropy in information theory avoided man-made subjectivism. Fuzzy comprehensive evaluating steps based on entropy weight were exemplified by a practical case. It is shown that the model developed is practicable and easy to apply. Therefore, it is worthy of study and is practicable in safety engineering applications.
