The problem is generalized in case the random variable has a unimodal failure rate function. This result is illustrated by a numerical example. In the example, the unimodal failure rate function is formed from a mixture of exponential distribution and a distribution with a quadratic and increasing failure rate intensity. 000022897 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000022897 653__ $$aoptimization problem, ageing class, failure rate function, reliability function, unimodal function 000022897 7112_ $$aEngineering Mechanics 2018$$cSvratka, CZ$$d2018-05-14 / 2018-05-17$$gEM2018 000022897 720__ $$aSzubartowski, M.$$iKnopik, L.$$iMigawa, K.$$iSołtysiak, A. 000022897 8560_ $$ffischerc@itam.cas.cz 000022897 8564_ $$s239469$$uhttps://invenio.itam.cas.cz/record/22897/files/857.pdf$$yOriginal version of the author's contribution in proceedings, page , section REL. 000022897 962__ $$r21225 000022897 980__ $$aPAPER
