Safety Status Index Optimization of Coal Mine Production Logistics Based on Grey Theory

In order to define the elements that affect coal mine production logistics and predict the safety status of coal mine production logistics accurately, the study proposes a method to construct the index system on coal mine production logistics safety status based on grey theory. According to coal mine production logistics operational status of each subsystem, study constructs a subjective hierarchical evaluation index firstly, and then, reduces index relativity by grey clustering, filtrates and optimizes the index system by grey relational analysis. This not only avoids the interference of human subjectivity, but also achieves the optimization of index system. This research laid a foundation for the evaluation of coal production logistics safety status in the future.
