Construction of healthcare system structure for reliability analysis

The principal goal of application of information technologies in medicine is improvement of medical care. Modern healthcare systems have to guarantee perfect care of patient. Therefore, the healthcare has to be characterized by high reliability first of all and reliability analysis of such system is an important problem. Most of the reliability analysis methods suppose the investigation of the structure of a system. But the healthcare system consists of heterogeneous components, such as software, hardware, human factor and etc. The structure definition for such system is a complex problem. We propose original approach for the construction of a healthcare system structure based on the monitoring of the system behavior. The monitoring examples are interpreted as Direct Partial Logic Derivatives of the structure function of the healthcare system. The structure function defines the correlation between system components states and system performance level unambiguously.
