Importance measures in reliability analysis of healthcare system

Abstract

Healthcare system is modern complex system that includes four principal components in point of view of reliability engineering. They are hardware, software, human factor and organization component. There are different methods in reliability engineering for analysis and quantification of every of these components. But new tendency in reliability analysis needs methods that evaluate the system as a single whole. In accordance with this tendency one aspect of reliability engineering (importance analysis) is considered in the paper. The importance reliability analysis allows to estimate influence of every healthcare system component to the system reliability and functioning. New algorithms for importance analysis of healthcare system are proposed in this paper. © 2012 Springer-Verlag Berlin Heidelberg.
