Weighted Grey Relation Evaluation Model on Colliery Safety Factors

Abstract:

Aiming at the shortage of existing grey relation model, the colliery safety factor evaluation index system is built with the weighted grey relation evaluation model which combines the subjective weighting process and the objective weighting process. The analysis conclusions of the four collieries of Zao Zhuang Coal Mining Co. Ltd show that the evaluation of colliery safety factors based on the weighted grey relation evaluation can make a good division and evaluation for various colliery safety factors, and also eliminate the gray characteristics the colliery safety system owns effectively, thus it can keep evaluation results objective and reasonable.
