Biomedical system engineering: methodology and aspects

Biomedical system engineering specificity is analyzed and new approaches to biomedical systems (BMS) projecting are proposed. Outlining of the system is equivalent to the assignment of the main function, the functional criterion of efficiency and the structure of functional subsystems. The certain objections are called by outlining medical and biomedical systems, which traditionally are considered to be purely technical: the bioobjects (either doctor or patient) are taken out of a system. Such outlining results in magnification of the duration of a projecting cycle, and decrease of its efficiency. From our point of view, it is necessary to consider a kind of bioengineering system, in which at least 2 subsystems are alive in nature. As a result, the system homeostasis is supported by new relations promoting an amplification of the undesirable tendencies of the system behaviour.
