论文摘要

结构控制理论可以应用于研究社会,经济和管理系统的控制原理。系统动力学(SD)是社会经济科学的目标领域,用于内生该理论,该理论为现实世界中的问题提供了建模解决方案。 SD模型采用示意图,使其成为利用类似图形表示的移植结构控制理论的理想基础。这项研究为在SD模型上进行结构控制分析(SCA)的理论基础,总结为SD从业人员的建模后工作流程,该工作流是社会经济科学中一般结构控制理论的特定应用。 SCA组件的理论和实用机构是协调开发的。具体来说,本研究解决了以下问题:(1)SD模型与图形表示中的物理控制系统有何不同,这些差异如何影响将结构控制理论应用于SD的方式? (2)如何在SD模型中识别控制输入,如何概念化SD模型中不同级别的系统控制? (3)重要的SD组件的结构控制属性是什么,这些特性和控制原理如何有助于证明SD实践中的建模启发式方法是合理的? (4)在SD模型中进行结构控制分析(SCA)的程序是什么?SCA结果对模型校准和决策的影响是什么?总体而言,这项研究为非线性动态模拟模型的系统控制分析提供了一般见解,该模型可能超出了SD并扩展到社会经济科学的各种学科。

Structural control theory could be applied to study the control principles of social, economic and managerial systems. System Dynamics (SD) is the target field in social-economic sciences for endogenizing this theory, a subject that provides modeling solutions to real-world problems. SD models adopt diagrammatic representations, making it an ideal ground for transplanting structural control theory which utilizes similar graphic representations. This study sets up the theoretical ground for conducting structural control analysis (SCA) on SD models, summarized as a post-modeling workflow for SD practitioners, which serves as a specific application of the general structural control theory in social-economic sciences. Theoretical and practical establishments for SCA components are developed coordinately. Specifically, this study addresses the following questions: (1) How do SD models differ from physical control systems in graphic representations, and how do these differences affect the way of applying structural control theories to SD? (2) How could one identify control inputs in SD models, and how could different levels of system control in SD models be conceptualized? (3) What are the structural control properties for important SD components, and how could these properties and control principles help justify modeling heuristics in SD practice? (4) What are the procedures for conducting Structural Control Analysis (SCA) in SD models, and what are the implications of SCA results for model calibration and decision making? Overall, this study provides general insights for system control analysis of nonlinear dynamic simulation models, which may go beyond SD and extend to various disciplines in social-economic sciences.
