A projection analysis of C2R models applied in grey prediction on OHASA18001 safety investment and benefit of a mining industry

A projection analysis of C2R model is adopted to calculate the safety investment, and benefit. On this basis, GM(1:1)model (Grey prediction model) is established to predict the safety benefit and safety investment values of 2017. This integrated method of C2R model and GM(1:1)model provides a direction and theoretical reference for optimizing the investment and a structure for the effective operation of mining industry occupational health and safety management system.
