ABSTRACT:This report offers an insight into common and distinctive qualities of structural models based on long term experience of structural modeling both technical and biological or medical systems. The results can be summarized as the following: there are obvious differences between structural models of physical and biological systems, as to the configuration of the physical systems models, it is simpler than it of biological systems and in physical systems models the measured parameters predominate. The parameters and their interrelations can be expressed quantitatively and systems faults are modeled as a deviation from the norm. The structural models in medicine depict modified physiological functions under pathological agents. They are characterized by an insufficiency of quantitative parameters. In addition, the prevalence of linguistic parameters is observed. The structural models of biological systems have characteristic qualities of both physical and medical systems models. Besides, the structural models differ according the aims they are made for: diagnosis, recovering, prevention or maintenance of functioning.

KEYWORDS: Structural modeling, technique, medicine
