Abstract The purpose of this research is to develop a computer‐aided tool for diagnostic and educational support of the living‐body circulatory system using the Human model devised by Coleman. The Human model is a dynamic model described by simultaneous differential equations, and consists of 25 physiological modules, such as the cardiovascular system, respiratory control, and kidney function, whose variables are exchanged with each other in order to emulate human‐body circulatory phenomena. For application of the human model to diagnosis and education, the supporting tool should have the capability of qualitative analysis to explain the causal relationships of numerical values of relevant variables in the model. We develop a supporting function to analyze the hierarchical structure of variables and parameters. The tool can be used to diagnose the causes of an unusual variable by path tracking in the human model. Furthermore, this supporting tool provides for editing of mathematical expressions for the purpose of validating the model. © 2001 Scripta Technica, Syst Comp Jpn, 32(14): 1–11, 2001
