Stroj so 160 prev\u00e1dzkov\u00fdmi hodinami a \u0161tyrmi poruchami m\u00e1 nameran\u00fa hodnotu MTBF 40 prev\u00e1dzkov\u00fdch hod\u00edn.

Podstatn\u00e9 je, \u010do v\u00e1m priebeh por\u00fach napoved\u00e1 o tom, \u010do treba presk\u00fama\u0165 a zmeni\u0165.

Samotn\u00e9 delenie je jednoduch\u00e9. Viac pozornosti si vy\u017eaduje to, aby prev\u00e1dzkov\u00e9 hodiny aj po\u010det por\u00fach vych\u00e1dzali z rovnakej defin\u00edcie. Sk\u00f4r ne\u017e si priprav\u00edte v\u00fdkaz, dohodnite sa s \u013eu\u010fmi, ktor\u00ed \u00fadaje zaznamen\u00e1vaj\u00fa, na \u0161tyroch veciach.<\/p>\n\n\n

Vymedzte sledovan\u00e9 zariadenie<\/h3>\n\n\n

Za\u010dnite konkr\u00e9tnym strojom alebo jasne ohrani\u010den\u00fdm syst\u00e9mom. Obr\u00e1bacie centrum, jeho vreteno a cel\u00e9 oddelenie obr\u00e1bania predstavuj\u00fa odli\u0161n\u00fd rozsah merania.<\/p>\n\n\n

Ak sledujete cel\u00fd stroj, porucha vretena, ktor\u00e1 mu znemo\u017en\u00ed vykon\u00e1va\u0165 po\u017eadovan\u00fa pr\u00e1cu, je poruchou stroja. V\u00fdmena s\u00fa\u010dasti vretena a op\u00e4tovn\u00e9 uvedenie stroja do prev\u00e1dzky neznamenaj\u00fa, \u017ee stroj treba pova\u017eova\u0165 za neopravite\u013en\u00fd v\u00fdrobok.<\/p>\n\n\n

MTBF mo\u017eno sledova\u0165 aj na \u00farovni linky, no za poruchu linky pova\u017eujte stratu jej po\u017eadovanej funkcie. Ak s\u010d\u00edtate v\u0161etky alarmy jednotliv\u00fdch s\u00fa\u010dast\u00ed, m\u00f4\u017eete jedno preru\u0161enie chodu linky zapo\u010d\u00edta\u0165 viackr\u00e1t.<\/p>\n\n\n

Definujte poruchu, nie iba zastavenie<\/h3>\n\n\n

Ur\u010dite po\u017eadovan\u00fa funkciu a udalos\u0165, ktor\u00e1 sa bude pova\u017eova\u0165 za jej stratu. Za poruchu mo\u017eno pova\u017eova\u0165 aj chybu zariadenia, pre ktor\u00fa stroj nedok\u00e1\u017ee sp\u013a\u0148a\u0165 po\u017eadovan\u00e9 prev\u00e1dzkov\u00e9 podmienky, hoci sa \u00faplne nevypol.<\/p>\n\n\n

Pl\u00e1novan\u00e1 \u00fadr\u017eba, be\u017en\u00e9 pretypovanie na in\u00fd v\u00fdrobok, nepr\u00edtomnos\u0165 obsluhy ani \u010dakanie na materi\u00e1l nie s\u00fa automaticky poruchami zariadenia. Tieto straty na\u010falej evidujte, ale nezah\u0155\u0148ajte ich do po\u010dtu por\u00fach.<\/p>\n\n\n

Dohodnite sa, ako budete evidova\u0165 kr\u00e1tkodob\u00e9 poruchy a opakovan\u00e9 resetovania. Viacero z\u00e1znamov alarmu po\u010das jednej neodstr\u00e1nenej poruchy sa nem\u00e1 po\u010d\u00edta\u0165 ako viacero nez\u00e1visl\u00fdch por\u00fach. Nov\u00e1 porucha po skuto\u010dnom obnoven\u00ed funkcie je novou udalos\u0165ou. Uchov\u00e1vajte p\u00f4vodn\u00e9 podrobn\u00e9 z\u00e1znamy, aby ste mohli opakuj\u00face sa poruchy presk\u00fama\u0165, namiesto toho, aby sa stratili v d\u00f4sledku nastaven\u00e9ho prahu pre vykazovanie.<\/p>\n\n\n

Zvo\u013ete, ak\u00fd \u010das budete mera\u0165<\/h3>\n\n\n

V tomto n\u00e1vode pou\u017e\u00edvame MTBF zalo\u017een\u00e9 na prev\u00e1dzkovom \u010dase<\/strong>: na hodin\u00e1ch, po\u010das ktor\u00fdch je sledovan\u00e9 zariadenie skuto\u010dne v prev\u00e1dzke v r\u00e1mci vymedzen\u00e9ho rozsahu merania. \u010cas opr\u00e1v ani in\u00fd \u010das mimo prev\u00e1dzky nevstupuj\u00fa do \u010ditate\u013ea. V\u00fdsledkom nie je priemern\u00fd kalend\u00e1rny interval medzi okamihmi vzniku dvoch po sebe nasleduj\u00facich por\u00fach.<\/p>\n\n\n

Poruchy zapo\u010d\u00edtavajte pod\u013ea toho, kedy v tomto obdob\u00ed vznikli.

Do celkov\u00e9ho \u010dasu odst\u00e1vok za dan\u00e9 obdobie zapo\u010d\u00edtajte len hodiny nedostupnosti, ktor\u00e9 do\u0148 spadaj\u00fa. Ak porucha presahuje hranicu obdobia, samostatne uchovajte \u00fapln\u00fd z\u00e1znam udalosti aj obnovenia prev\u00e1dzky.<\/p>\n\n\n

Pri ka\u017edej poruche uchovajte identifik\u00e1tor stroja, \u010das vzniku, \u010das obnovenia prev\u00e1dzky, pozorovan\u00fd pr\u00edznak alebo sp\u00f4sob poruchy a relevantn\u00e9 prev\u00e1dzkov\u00e9 podmienky.
