4.2 Raws li kev tsim software
4.2.1 BOM hauv CAD
Tus tsim chav ua haujlwm yog tus tsim lub BOM thiab tus neeg siv ntawm BOM. Ib qho khoom xws li cov duab kos, cov khoom siv (yam khoom 45 fais fab), hnyav, ntim, tsim kev hloov kho, hnub pib siv, thiab lwm yam .; yam khoom sab nraud los yog lwm yam khoom muaj xws li sab nrauv, khoom siv, qhov chaw dav, Qhov nruab nrab, qiv qhov chaw, sib sau ua ke ntawm txhua qhov ntawm ib sab, ib feem ntawm daim duab, thiab lwm yam .; kev teeb duab, kev siv khoom, cov ntaub ntawv pov tseg, cov ntawv pov thawj, thiab lwm yam. Cov no yog tag nrho cov ntaub ntawv BOM.
Hauv qhov kev tsim fab (CAD), qhov kev sib tham nrog BOM yog daim ntawv teev npe, uas yog ib daim ntawv pov thawj uas tsom rau cov ntaub ntawv xov xwm khoom sib sau.
Tus tsim chav tsom kwm BOM cov lus qhia los ntawm tus xov tooj ntawm cov khoom ntawm ib hom qee yam. Tom qab tau txais daim ntawv xaj, tus tsim chav ua haujlwm yuav ua raws li qhov yuav tsum tau ua. Raws li ib txwm muaj, peb muaj peb lub tswv yim tsim: cov qauv saum toj-down, tsim daim qauv hauv qab, thiab nruab nrab-rau-ob daim qauv tsim.
Tsis hais txog kev tsim qauv, lub koomhaum ntawm tus lej naj npawb yog zoo ib yam. Cov ntaub ntawv xov xwm no muab tso ua ke raws li tus najnpawb zauv, thiab tag nrho cov sij hawm, cov txheej txheem cov lus teev tseg, cov khoom yuav ntaws cov lus piav qhia, thiab sab nraud ntawm qhov khoom tsim. Cov nplooj ntawv xaus, thiab lwm yam., Kuj tuaj yeem tsim cov khoom catalogs thaum tsim nyog (rau cov neeg muas zaub los sis cov tuam txhab tawm sab nrauv uas tsis khiav ERP systems).
Qee lub sij hawm ib qho zoo tib yam nyias muaj nyias cov zauv vim nws yog cov khoom sib txawv, vim li ntawd nws tsis yog qhov yuav tsum tau xav txog lub ntsiab lus ntawm lub tuam txhab khoom. Nws yuav tsum raug sau tseg tias tom qab tsim cov nqi ntawm cov ntaub ntawv, txhua cov ntaub ntawv muaj ib cov cai cim, uas yog, cov khoom naj npawb. Tsis txhob qee yam khoom npe (CAD raws li BOM) nrog BOM cov ntaub ntawv hauv ERP.
Cov lus qhia txog cov lus qhia hauv chav tsim tsim yog hloov mus rau hauv cov ntaub ntawv BOM hauv ERP system. Nws yuav tsum muaj kev koom tes ntawm lub chav tsim, lub koom haum thiab lub koomhaum kev tsim khoom, thiab kev tswj cov khoom kev sib raug zoo ntawm PDM (khoom siv cov ntaub ntawv tswj) tsim los daws cov khoom sau thiab BOM. Qhov sib thooj thiab sib txawv ntawm cov ntxhuav, tshwj xeeb yog qhov tsis sib haum ntawm tus najnpawb zauv thiab tus nab npawb (tus qauv PDM khoom qauv yog ua tiav los ntawm nws txoj cai tswjfwm, cov kev hloov thiab cov haujlwm sau ua haujlwm).
Raws li kev siv, thaum twg cov qauv khoom hloov, lossis cov qhua tuaj hloov cov ntaub ntawv, muaj qhov teeb meem zoo, lossis rov tsim dua ib feem, tsim tsab ntawv ceeb toom tsim nyog yuav tsum tau txais kev pom zoo kom meej meej. raws li. Hauv txoj kev qhia ntawm kev hloov daim ntawv ceeb toom kev tsim qauv, lub tuam tsev tsim tau txais cov ntaub ntawv nyob rau txhua qhov chaw thiab lawv cov ntaub ntawv qhia los ntawm BOM cov lus qhia.
Tsuas yog los ntawm kev muab cov ntaub ntawv no tuaj yeem muab txhais, piav qhia lossis hloov kho thiaj li yuav tsim tau txhua zaus (tshwj xeeb yog tus neeg mob daim ntawv ceeb toom ceev). Raws li tus qauv tsim qauv qhia, nrog PDM kev txhawb nqa, nws yog ib qho yooj yim los muab kev hloov cov ntaub ntawv thiab qhia cov kev ua ub no xws li kev tsim khoom, kev xa tawm, thiab kev pab tom qab muag.
Hauv cov txheej txheem ua haujlwm ntau dhau, tsim cov kev hloov yog qhov tseem ceeb tshaj uas yuav ua rau cov ntaub ntawv tsis muaj tseeb, yog li yuav tsum muaj txheej txheem tsim cov kev hloov kev ceeb toom kev tswj cov kev tswj cov kev hloov cov qauv tsim. Txij li nws yuav muag, muag, tsim, engineering, nyiaj txiag, thiab lwm lub tuam tsev, qhov kev hloov daim ntawv tshaj tawm yog feem ntau tswj los ntawm lub tuam txhab cov thawj coj loj. Cov txheej txheem no yog ua rau tsib theem kev qhia kom paub hloov kev txheeb xyuas, kev tsom xam, kev pom zoo, cov ntaub ntawv thiab kev saib xyuas. Ib feem ntawm cov ntaub ntawv tau tsim los ntawm chav tsim (CAD) yog ua los ntawm PDM thiab xa mus rau ERP system.
Nws muaj ntau lub tswv yim ntxiv rau qhov tsim kom muaj BOM:
Lub Cheeb Tsam ntawm Cheeb Tsam ntawm cov qauv khoom ntoo tau muab faib ua peb pawg: tus qauv, qhov sib txuam, thiab tsim qhov chaw.
Txoj kev tsim cov khoom tsim tsim muaj peev xwm tsim los ntawm cov 3DCAD sib txawv lossis 2D CAD cov sijhawm, thiab yog tsim los ntawm peb lub koomhaum lossis cov qauv cog kev tsim.
Cheeb Tsam Cheeb Tsam Tsev Kawm Ntawv yuav muaj duab los sis kos duab yooj yooj yim. Cov npe ntawm cov khoom tsim coj los ntawm cov khoom siv feem ntau yog cov khoom qauv kos duab, cov khoom qauv saw, qauv khoom sib dhos, khoom ntim, thiab lwm yam.
Cov ntaub ntawv no yuav tsum muaj nyob rau hauv ntau lub tuam tsev cov qauv khoom ntoo, tab sis cov ntaub ntawv no tuaj yeem tsis tau ntawm lub rooj sib txoos ua ke. Piv txwv, cov qauv duab kos thiab qhov khoom sib dhos yog qhov siv tau yog hais tias lawv tau dai ntawm qhov khoom siv, tab sis tus cwj pwm neeg siv feem ntau yog qhov khoom ua qauv duab. Nws yog tib theem li qhov khoom sib dhos khoom; tsis tas li ntawd, lub thawv ntim hauv subtree yuav tsum tau tsim muaj manually tom qab lub hnab ntim cov pob ntawv nthuav, thiab tsis tuaj yeem sib txuas ncaj qha los ntawm cov lus ntxaws los ntawm BOM expansion.
Cov ntsiab lus tseem ceeb muaj xws li cov khoom nruab nrab ntawm cov tsev qiv ntawv thiab cov tuam txhab thiab cov tuam txhab kev lag luam. Thiab muaj peev xwm muab hloov kho thiab muab deleted thiab sib sau ua ke, ntxiv ib qhov chaw qiv ntawv kom zoo zoo xyuas cov txheej txheem. Cov tshav dav hlau tuaj yeem hloov tau los ntawm qhov qiv nyiaj.
Tib yam khoom, nws cov yam ntxwv ntawm yam ntxwv, thiab qee qhov tsim tsim lossis qhov khoom txheem yuav muaj ntau txoj kev xaiv. Yog li, tib yam khoom tsim thiab kev muag khoom hais tau muaj ntau cov qauv ntaub ntawv ua ke (xws li cov nqi, cov khoom siv, lub sijhawm hnub) rau cov neeg siv khoom sib txawv.
Txawm li cas los xij, cov kev mob no feem ntau tswj tuav hauv ERP system, thiab qhov PDM tsuas xav tau kom muaj lub meej mom thiab sib luag ntawm cov ntaub ntawv.
