Abstract

The paper presents semi-Markov models of technical state transitions for diesel engines, useful for determining reliability of the engines. A possibility of application of a three-state model with a simplified matrix function, or even a two-state model, to determine reliability of the engines, has been described herein on examples of known from literature semi-Markov models, for the case when appropriate diagnosing systems (SDG) are used to identify technical condition of the engines considered as diagnosed systems (SDN)). A risk function and a renewal (restitution) function have been proposed to apply for developing a two-state model of engine state transitions. An opportunity of considering reliability of diagnosis while making operational decisions by applying the statistical decision theory, has also been presented. Conditional probability P(si/Ki) is recognized as a measure of reliability of diagnosis.
