- The paper presents reasons for the need of discerning the notions: likelihood of diagnosis and rightness of diagnosis while taking operating decisions. A probability formula for establishing the right diagnosis has been derived as a likelihood measure of diagnosis. For deriving the formuła, the theory of semi-Markov processes and Bayes' formula of the conditional probability have been applied. Other probability measures of likelihood of diagnosis have been also presented. These measures concern the technical state of such important systems as combustion engines of sea-going ships. However, they can be of use also for other ship systems. The paper provides description of a stochastic decision situation following from operation of combustion engines in any operating system and on this background there is presented some proposals of applying the technical diagnostics for controlling the engine operating process. Formulating a problem for the combustion engines, solving the problem, diagnostic inference and likelihood of diagnosis as well a simplified model of combustion engine operation taking into account diagnosis and control in time of operation are presented in the paper.
