Abstract


Create a system dynamics model is the structure of the system of qualitative analysis and quantitative analysis. Structural modeling of the system , experts in different fields have different opinions, so-called matter of opinion, but the lack of normative modeling . Therefore, how to regulate the establishment of system dynamics model of the structure is an important issue. Structure of the system modeling method are reviewed proposed system architecture modeling necessity of standardization . According to the system of scientific theories , theoretical analysis through differential equations proposed system dynamics model into a tree structure diagram of the two segments improved methods and theories through case analysis and simulation analysis to verify the validity of the new method . Based on the characteristics of various modeling methods , structural equation modeling approach and the establishment of the special advantages of the needs of system dynamics model is proposed structural model of system dynamics modeling steps : First , a clear problem ; Second, determine the system boundary ; Third, the use of factor analysis the system is divided into several subsystems , and then use the rhombus thinking patterns to determine the elements of each subsystem ; Fourth, the application of structural equation modeling method to establish the structural model of the system ; Fifth, the establishment SD structural model . And Gan River Basin water ecological carrying capacity of an example for empirical analysis . Established the Gan River Basin water ecological carrying capacity SD structural model .
