Abstract
System dynamics is a quantitative method used to study the complex social economic system by means of computer simulation technology. In this paper, the system dynamics was introduced to build security economic decision-making model for enterprises. With the method of system thinking, the influence factors of safety investment system are identified and the casual relationships between various factors are found to determine the internal influence mechanism that the safety investment impacts on the accident risk and economic output. Based on accident control theory and system dynamic modeling system, the system of security economic decision-making was built, including enterprise production subsystem, employee security subsystem and technology and equipment subsystem. Finally, Vensim system dynamics modeling software was used to simulate the built model. Then the proportion of enterprises' safety resource allocation was adjusted to seek for the optimal investment plan.
