A NOVEL INTUITIVE DYNAMIC MODELLING METHOD FOR DIGITAL IC SYSTEMS IN NUCLEAR POWER PLANTS

摘要

Conventional static reliability analysis methods are inadequate for modelling dynamic interactions between components of a system. Various techniques have been proposed for modelling dynamic systems based on improvement of the conventional modelling methods. However those methods are inadequate to apply to digital instrumentation & control (I&C) systems in nuclear power plants from the viewpoint of intuitiveness. In this paper we introduce dynamic nodes to the existing reliability graph with general gates (RGGG) as an intuitive modelling method to model dynamic systems including the digital I&C systems.
