7.4. SINHRONІZATSІYA TSIKLІV VIROBNITSTVA

Sinhronіzatsіya tsiklіv vigotovlennya virobіv that їh Chastain Je warehouses whether yakogo virobnichogo processes, ale yavische tse, yak usually nepomіtne, tobto yogo nachebto Absent. Yakscho sinhronіzatsіya tsiklіv protsesіv nekerovana, trivalіst tsiklіv zrostaє vtrichі, to scho todі calendar virіvnyuvannya kozhnoї Chastain processes perevischit rozmіr naybіlshogo cycle vіdpovіdnoї Chastain processes. Tse is true for skin rіvnya rozpodіlu processes vigotovlennya virobu at Chastain: operatsіya, detail, komplektooperatsіya, kit of parts, stadіya vigotovlennya virobu (zagotіvelna, mehanoobroblyuvalna, skladalna). Nekerovana sinhronіzatsіya generally produces up perevischennya digit ratsіonalnogo rіvnya UNFINISHED virobnitstva that sprichinyaє velikі vtrati robochem hour robіtnikіv i obladnannya (by now a non-threaded virobnitstvі tsі vtrati robochem hour syagayut 50%). Knowledge of the law sinhronіzatsії tsiklіv protsesіv vigotovlennya virobіv that їh Chastain neobhіdnі yak basis Mistetstvo keruvannya virobnichim processes h metoyu mіnіmіzatsії vitrat on virobnitstvo. For zabezpechennya konkurentospromozhnostі pіdpriєmstva mozhlivіst mіnіmіzatsії vitrat on virobnitstvo Got yak usually pershochergove values.

Mіzhoperatsіyne prolezhuvannya predmetіv pratsі that prostoї robochem mіsts in protsesі vigotovlennya virobіv sluguyut svoєrіdnimi calendar compensators, scho virіvnyuyut calendar trivalіst sumіzhnih tehnologіchnih operatsіy on virobnichih dіlnitsyah.

Calendar organіzatsіya usіh forms stream virobnitstva ґruntuєtsya on printsipі bezperervnogo Ruhu details: sinhronіzatsіya trivalostі detaleoperatsіy then small b zdіysnyuvatis tіlki for rakhunok prostoїv robochem mіsts, Ale tse not Je efektivnosti, to scho Godin downtime robochem Georeferencing (robіtnika i obladnannya) koshtuє dorozhche nіzh hour prolezhuvannya odnієї detalі. Tom organіzovuєtsya parallel-ruh poslіdovny parts, if usі mіkroprostoї robochem mіsts kontsentruyutsya.

Kontsentratsіya staє mozhlivoyu for rakhunok poached deyakogo mіzhoperatsіynogo prolezhuvannya details. Kontsentratsіya mіkropauz prostoїv skin robochem Georeferencing dozvolyaє zvіlniti robіtnika i on Tsei hour yogo translate into another operatsіyu. Here sinhronіzatsіya trivalostі detaleoperatsіy schodo rozmіru tact potochnoї lіnії vіdbuvaєtsya yak rakhunok for prostoїv obladnannya robochem mіsts, so i for rakhunok mіzhoperatsіynogo prolezhuvannya details.

For whether yakoї FORMS organіzatsії virobnitstva nerіvnі trivalostі tehnologіchnih operatsіy virіvnyuyutsya to deyakoї kalendarnoї mezhі abo for rakhunok prolezhuvannya details abo for rakhunok prostoїv robochem mіsts, abo for rakhunok th of іnshogo odnochasno. Virіvnyuvannya trivalostі tehnologіchnih operatsіy in a non-threaded virobnitstvі Got Dvi ob'єktivnі reasons. Persha polyagaє in the fact scho for drain-line virobnitstva organіzatsіya bezperervnostі protіkannya virobnichogo processes in a non-threaded virobnitstvі vimagaє sinhronіzatsії trivalostі operatsії. Another reason virіvnyuvannya - neobhіdnіst komplektuvannya partіy predmetіv pratsі in protsesі їh vigotovlennya to rozmіrіv scheduled oblіkovoї odinitsі (car kits, umovny kit brigadokomplekt, Trip set toscho).

Calendar boundary virіvnyuvannya trivalostі tehnologіchnih operatsіy harakterizuє virobnichy processes oboh s yogo protilezhnih bokіv - yak bezperervnіst zavantazhennya robochem mіsts (Rj) i yak bezperervnіst vigotovlennya predmetіv pratsі (Ri).

Not viklikaє sumnіvіv those scho Quest organіzatsіyno-tehnologіchnih minds mіnіmum vitrat on virobnitstvo dosyagaєtsya at naybіlshіy bezperervnostі vikoristannya zasobіv virobnitstva (robochem mіsts) and tse vіdpovіdaє єdinomu optimal rіvnyu vigotovlennya partіy virobіv in virobnitstvі (Re).

Ob'єmno-dinamіchny method planuvannya th organіzatsії virobnitstva the principle bezperervnogo zavantazhennya planned robochem mіsts daє zmogu zabezpechiti not tіlki bezperervne zavantazhennya planned robochem mіsts and minutes Maximum trivalіst virobnichogo cycle route stvorennya analіzovanogo kit of parts (T MDC). Yakscho on kozhnіy operatsії processes vigotovlennya routing kit of parts (tobto on komplektooperatsії) vikoristovuєtsya odne chi bіlshe robochem mіsts then trivalіst yogo virobnichogo cycle can viznachiti of the formula:

de n? - Quantity naymenuvan virobіv, scho will vigotovlenі on dіlyantsі in Pevnyi planned perіodі i skladayut one set of parts;

- Serednіy іnterval hour, through yaky zdіysnyuєtsya transfer partії virobіv one naymenuvannya on the following komplektooperatsіyu pіslya completion їh obrobki to the j-th komplektooperatsії

- Mensch s dvoh serednіh іntervalіv hour through SSMSC zdіysnyuєtsya transmission parts kit s sumіzhnih -ї chi j (j + 1) -ї komplektooperatsіy;

Cj - Quantity robochem mіsts, vikoristanih in obrobtsі parts kit on bіlsh vuzkіy j th komplektooperatsії;

tj - serednya trivalіst vikonannya tehnologіchnih operatsіy s vigotovlennya parts kit for the j-th komplektooperatsії (chi on

j-th rіvnі robіt);

j - serial number komplektooperatsії chi operatsії tehnologіchnogo typical route for Yakima detalі zaznachenogo kit passing obrobku (j = 1, m).

Here cycle vigotovlennya kit of parts viznachaєtsya s urahuvannyam minds organіzatsії virobnichogo Process: kіlkostі nomenklatura pozitsіy in planі (n?); kіlkostі robochem mіsts scho vikoristovuyutsya on kozhnіy operatsії Process (Cj); serednoї trivalostі vikonannya odnієї tehnologіchnoї operatsії s piece set in the j-th kozhnіy komplektooperatsії (Re). For tsієyu formula viznachaєtsya phone reception mіzh kіlkіstyu nomenklatura pozitsіy in planі, planning-of-line vikonannya robіt i Normative rozmіrom partії details.

Calendar sinhronіzatsіya tsiklіv vigotovlennya details Got yavny character. So, Yakscho detalі toil odnakovu Quantity operatsіy then їh cyclic virіvnyuyutsya vnaslіdok virіvnyuvannya trivalostі operatsіy s їh vigotovlennya. Detalі in virobnichih pіdrozdіlah vigotovlyayutsya, yak rule sets, and tse oznachaє scho trivalіst cycle vigotovlennya kozhnoї detalі kit dorіvnyuє trivalostі cycle vigotovlennya danogo kit of parts.
