为了将汪培庄先生提出的因素空间与因素库理论应用到实际研究,本文就该理论的特点,应用其概念分析和推理能力,考虑到目前煤矿安全分析大多采用定性论述的现状,对煤矿的安全情况论述使用概念分析表进行了推理和化简,以降低安全性论述中冗余信息对定性安全评价的影响,得到简洁准确的安全性概念,从而对不同煤矿企业的安全情况进行区分.结果表明:在研究对象集合U和因素集合F不变的情况下,按照不同的因素排序进行划分得到的概念格是不一样的;初始的安全性描述可以通过合理安排因素排序和去掉虚分得到较为简化的概念格,而得到相应简化的安全性描述;使用因素空间与因素库的概念,对安全性概念进行推理并化简是可行的,可用于区分多个煤矿的安全情况的差别,并进行分级和对比.
In order to apply the theory of factor space and factor library put forward by Mr. Wang Peizhuang to practical research, this paper applies the concept analysis and reasoning ability of the theory. Considering that the current status of the coal mine safety analysis is mostly qualitatively discussed, Discusses the reasoning and simplification using the concept analysis table, in order to reduce the impact of redundant information on the qualitative security evaluation in the security discussion and get the concise and accurate concept of security to distinguish the security situation of different coal mining enterprises.The results show that: In the case of the same set U and the same set F of factors, the concept lattices are divided according to different factors. The initial security descriptors can be simplified by reasonably arranging the factors and removing the imaginary ones Concept Lattice, and get the corresponding simplified security description. It is feasible to use the concept of factor space and factor library to reason and simplify the concept of security, and it can be used to distinguish the difference of safety conditions among multiple coal mines, Compared.
