【摘要】 计算出系统动力学(简称SD)模型中的反馈环是系统动力学复杂系统反馈分析的基础，这也是目前许多系统动力学仿真软件没有解决的问题。流率基本入树建模法不仅实现了规范化建模，而且有利于反馈环的计算和反馈性分析清晰化。本论文在研究了系统动力学及流率基本入树建模法的基础上，通过比较常见反馈环计算的方法，得出在时间复杂度上枝向量矩阵算法优于其它方法。依据此算法，运用功能强大的MATLAB设计出了用于SD模型反馈性分析的软件MSAFL。论文详细介绍了软件的实现和设计过程。最后，结合“公司+农户”规模经营模型说明了此软件的使用，并验证了其有很好的应用效果。结果表明，MSAFL软件大大提高了系统动力学建立和分析模型的效率。更多还原

【Abstract】 To search feedback loops of system dynamics (SD) models is the basis of complex system feedback analysis of system dynamics, which hasn’t been solved by many simulation softwares of system dynamics at present. SD rate variable fundamental in-tree modeling not only realizes standardization of modeling but also is beneficial to calculation of feedback loops and perspicuity of feedback analysis.On the basis of researching system dynamics and SD rate variable fundamental in-tree modeling and compared with some normal methods of searching feedback loops, we obtain that branch vector matrix algorithm is superior to others with regard to time complexity. In terms of this algorithm, the software MSAFL for feedback analysis of SD models was designed in virtue of powerful MATLAB language. This paper introduces the process of implemention and design of the software in detail. At last, we introduce how to use the software and validate its wonderful application effect according to "Company & Farmer" management modeling. The result shows that the MSAFL software greatly improves the efficiency of establishment and analysis of system dynamics models.更多还原
