Plow Plane Multi-level Fuzzy Evaluation Based on Gray Level Correlation Decision Model and Entropy Value Law

The evaluation of the thin coal mining plow equipment based on the traditional method suffers from its subjective nature and measurement difficulties. This paper proposes an assessment method of the plow based on the entropy value law and the gray level correlation theory, and the recursive operation is used according to the normalized formula, to calculate membership functions of all levels separately, to establish the gray level correlation decision-making model for the plow. The results show that the evaluation method is feasible, and the plow planning predicted results agree very well with the actual test results. Taking Shaanxi province Nanliang mine as an example, a three-level evaluation model is built for Shanxi province Nanliang mine, for the multi-level fuzzy calculation. The calculation results show that the plow adaptive multi-level fuzzy evaluation analysis system is effective for China coal seam.
