Optimizing the periodicity of machine maintenance with respect to the underused resource

  • 1 Institute of Soil Science, Agro-Technology and Plant Protection “Nikola Pushkarov", Sofia, Bulgaria


The intensity of aging and wear of the components /aggregates and assemblies/ of the machines is different and hence the necessity of carrying out repair service interventions has different periodicity and volume.
A model has been developed to optimize the periodicity of maintenance of machine components, taking into account the losses from the underuse of their resource.
The influence of the parameters of the law and the economic indicators on the optimal periodicity of the maintenance was examined at the density of the distribution of work until failure to the Weibull distribution.
