Production Safety Evaluation Model Based on Principal Component Analysis

This paper carry out principal component analysis for daily production safety assessment data based on principal component analysis (PCA). By defining principal component weighted mean aggregation operator and weighted geometric aggregation operators, we construct 6 comprehensive evaluation functions with different properties to establish a new production safety evaluation mathematical model. The proposed model can achieve safety assessment from the scattered data and qualitative analysis into systematically quantitative analysis, simplify the data processing work of safety evaluation, and provide effective analysis techniques for the daily production safety from the point of view of the time point, individual and overall. At last, apply the model to the assessment in coal mine driving production safety, and the results proved its usefulness and effectiveness. (C) 2011 Published by Elsevier Ltd.
