Summary
Studující se podrobně seznámí s obsahem pojmů provozuschopnost, bezporuchovost,
spolehlivost, životnost a se způsoby zjišťování bezporuchovosti, spolehlivosti,
životnosti atp. Naučí se zjišťovat ukazatelé spolehlivosti R(t), F(t), f(t),
lambda (t) a vynášet je jako funkce do grafů. Seznámí se se zkouškami
spolehlivosti. Seznámí se s druhy poruch a jejich klasifikací. Budou se zabývat
bezporuchovostí soustav a metodami jejího zvyšování (zálohování apod.). Dále se
posluchači seznámí se systémy moderní údržby a metodami údržby (údržba podle
reálného stavu technických prostředků, proaktivní údržba, korektivní a následná
údržba).
