Semi-Markov model for the Kaplan preventive repair system for water turbines
M Czyżewska, K Migawa… - MATEC Web of …, 2023 - matec-conferences.org
The article presents a semi-Markovian model of a system of preventive repairs according to
age, carried out in water power plants with the use of Kaplan turbines. In the case of the
analyzed technical objects, the profit per unit of time is considered as a criterion for the
considered function. On the basis of the adopted assumptions, formulas describing the
criterion function were presented for the developed mathematical model, and then the
conditions for the existence of the maximum of this function were formulated. The proposed …

Semi-Markov model for the Kaplan preventive repair system for water turbines with periodic inspection of the technical condition
K Migawa, A Sołtysiak, M Czyżewska… - MATEC Web of …, 2021 - matec-conferences.org
The paper presents a semi-Markow model of a preventive repair system by age,
implemented in hydroelectric power plants with Kaplan turbines. In the case of the analyzed
technical objects, the profit per time unit is considered as the criterion of the quality of
functioning. On the basis of the adopted assumptions, for the developed mathematical
model, formulas describing the criterion function were determined and the conditions for the
existence of the extreme (maximum) of this function were formulated. The proposed method …
