Qualitative and quantitative evaluation of the security degree for Chinese iron and steel industry

Abstract

In order to objectively measure the security degree for Chinese iron and steel industry, a security evaluation system is proposed. The proposed system includes 12 carefully selected indexes which are designed based on industrial domestic environment, industrial international competitiveness, industrial dependence on foreign and industrial control. Analytic Hierarchy Process (AHP) is used to obtain the index's weight. Linear comprehensive model is adopted and nonlinear comprehensive evaluation model is proposed to aggregate the indexes together. To demonstrate the validity of the proposed system, the evaluation of the security degree for Chinese iron and steel industry from 2000 to 2010 has been conducted. Results have shown that the system can effectively reflect the security status. © Springer-Verlag Berlin Heidelberg 2013.
