Structure Function Based Methods in Evaluation of Availability of Healthcare system.

Reliability analysis is important properties of any system and healthcare system too. The healthcare system has some specifics in reliability analysis. One of them is the heterogeneity, because this system includes components with different background, kind and properties (for example, equipment and human factor). Other specific of healthcare system is great influence of human factor. Typically, the influence of human factor is evaluated by special methods from special part of reliability engineering that is known as Human Reliability Analysis (HRA). But these methods can not be used for evaluation of technical part (components) of healthcare system. In this paper new method for healthcare system evaluation is developed. This method is proposed for the quantitative analysis of healthcare system and, in particular, for Importance Analysis of this system. It is based on the application of mathematical representation that is named Multi-State System (MSS) to indicate some (more than only two) performance levels in investigated system for more details analysis. In this paper the representation of healthcare system in form of Multi-Valued Decision Diagram is used, that typically used for the system of large dimension.
