A system dynamics model for integrated environmental and economic accounting环境与经济综合核算的系统动力学模型绿色GDP科学发展观可持续发展系统动力学环境经济核算环境与经济综合核算(绿色GDP核算)是最主要的评价经济增长真实状况的手段之一.然而,绿色GDP的核算在国内外却备受争议.其原因就在于核算方式是不完整的,静态...
In order to do so, we need to have a model that highlights our objectives and visions. In this research, System Dynamics (SD) is being used for productivity modeling for the first time. A System Dynamics is a concept the enable us to understand the complexity of any systems. This ...
The system dynamics (SD) model is suitable for the study of complex systems that exhibit nonlinear, multi-feedback and time-varying properties (Yang et al., 2019). The SD model provides a feasible way to simulate the behaviors of the WEFN system and predict future scenarios. Many existing ...
Therefore, this study aims to develop a conceptual System Dynamics (SD) model to analyse cybersecurity in the complex, uncertain deployment of CAVs. Specifically, the SD model integrates six critical avenues and maps their respective parameters that either trigger or mitigate cyber-attacks in the ...

and the model parameters: m Mass of the vehicle [kg]. a Distance from front axle to COG [m]. b Distance from rear axle to COG [m]. Cx Longitudinal tire stiffness [N]. Cy Lateral tire stiffness [N/rad]. CA Air resistance coefficient [1/m]. The outputs of the system are the lon...
An illustration of a set of six tests for structural validity of a system dynamics model for energy policy analysis follows. Then using Theil inequality statistics, the behavior validity of the model is also tested. Finally, some conclusions on the increased appeal for simulation models for energy...
