MODELLING OF DYNAMIC RELIABILITY STAGES OF A SHIP PROPULSION SYSTEM WITH SAFETY AND EXHAUST EMISSION

This paper elaborates on the efficacy of application of the combination of Markov chains and systematic-dynamic modelling during research on technical systems reliability problem. The original mathematical model of a ship propulsion system has been shown in six stages. The very combination of Markov model with systematic-dynamic model contributes to original solution to the problem of the ship propulsion system reliability. By the application of systematic-dynamic simulation model it is possible to quantify the system structure maintenance efficacy parameters and enable better reliability and availability of a specific technical system. Simulation programme POWERSIM has been used to simulate the subject simulation model. AMOS maintenance programme package data base has been applied, which is being used on board the m/v Explorer. On the basis of the results obtained it is possible to plan and timely and efficiently influence a higher quality ship propulsion systems management.Original Abstract: U radu je prikazana uspjesnost primjene spoja Markovljevih lanaca i sustavno dinamickog modeliranja pri istrazivanju problema pouzdanosti tehnickih sustava. Prikazan je originalni matematicki model brodskog porivnog sustava sa sest stanja. Sam spoj Markovljevog modela sa sustavno dinamickim simulacijskim modelom, doprinosi originalnosti rjesavanja problema pouzdanosti brodskog porivnog sustava. Primjena sustavno dinamickog simulacijskog modela omogucuje kvantifikaciju parametara efektivnosti odrzavanja strukture sustava i utjece na poboljsanje pouzdanosti i raspolozivosti konkretnog tehnickog sustava. Izradeni simulacijski model simuliran je pomocu simulacijskog programa POWERSIM. Koristena je baza podataka programskog paketa odrzavanja AMOS, koji se koristi na M/B Explorer. Na temelju dobivenih rezultata moze se planirati te pravodobno i ucinkovito utjecati na kvalitetnije upravljanje brodskim porivnim sustavima.
