【摘要】 针对系统动力学(System D ynam ics,简称SD)模型中枝向量行列式算法只用于计算经过流入流率和流出流率的合流率的全部反馈环的情况,运用组合数学的思想,对原有算法进行拓广,使之能计算出经过各独立流率的全部反馈环,给出相应算例。算法与原模型完全对应,为分析模型提供了更大的方便。更多还原

【Abstract】 The algorithm for branch vector determinant in system dynamics has been only used to calculate the whole feedback loops based on the compound rate variable as yet.By the thought of combinatorial theory applied,the algorithm is extended to calculate the whole feedback loops based on the independent rate variable.The extended algorithm is fully corresponding to the original model,and it can express the model’s thought clearer,so it is more convenient for analyzing a model.更多还原
