Abstract
Aiming at the existing relevant problems in cost management for the projects of petrochemical enterprises, this paper includes a large quantity of practical data and summarizes the indicators which influence the cost of projects of petrochemical enterprises into 14 indicators including investment scale, integrated operation, key technologies of production, and environment. DEMATEL quantization algorithm is used to calculate and rank above 14 indicators. Research conclusion indicates that the ranking (from the high to the low) of importance degree of indicators which influence the cost of projects of petrochemical enterprises can be cost, investment scale, logistical support, social responsibility, key technology of production, management of production quality and so on. They are the main driving forces which influence other cost indicators. While analyzing and forecasting cost, environment, investment scale, production technology, logistical support and the social responsibility taken by enterprises shall be firstly considered. Other factors are secondary. In the latest years, petrochemical enterprises consider more cost of environment. The concentration of SO2 lowers largely. It lowered for 107.2% in 2015 comparing with that in 2006. The complex energy consumption of production value per ten thousand yuan declined for about 31.4%.
