Decisions made about the renovation or replacement of machinery and equipment are mainly based on the last two types of deterioration and are therefore dependent on the physical condition of the machinery and equipment or on external circumstances, e.g., regulation changes. Such decisions are usually not supported by studies of economic feasibility. Economically feasible renovation or replacement of machinery and equipment is usually primarily dependent on functional obsolescence. The paper is a detailed study of the role of functional obsolescence in the process of making decisions about renovation and the replacement of machinery and equipment. We have given special attention to measuring the curability of this obsolescence. We have, for this reason, introduced the term quotient of curability of functional obsolescence. This quotient is based on the relation between the present value of the quantified effects of functional obsolescence for machinery and equipment, and the investment necessary for its repairDelovna zastarelost strojev in opreme se velikokrat pojavlja v senci fizične obrabe oziroma gospodarske (ekonomske) zastarelosti. Na teh oblikah poslabšanja, torej v odvisnosti od fizičnega stanja strojev in opreme oziroma v odvisnosti od zunanjih vplivov (npr. spremembe predpisov), temeljijo tudi odločitve o obnovi ali zamenjavi strojev in opreme. Taksne odločitve praviloma niso podprte s studijami ekonomske upravičenosti. Ekonomsko utemeljene obnove ali zamenjave strojev in opreme pa se opirajo predvsem na preučitev njihove delovne zastarelosti. V tem prsipevku podrobno obravnavamo vlogo delovne zastarelosti v postopku odločanja o obnovi ali zamenjavi strojev in opreme. Posebno pozornost smo namenili merjenju njene ozdravljivosti. V ta namen smo vpeljali tako imenovani količnik ozdravljivosti delovne zastarelosti, ki temelji na razmerju med sedanjo vrednostjo ovrednotenih učinkov delovne zastarelosti ter med vložkom, ki je potreben za njeno odpravoTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
