IDEF0 umdwebo: izibonelo kanye nemithetho wokwakha

IDEF0 umdwebo esakhiwe usebenzisa uhlelo BPWin. Ahloselwe ukumodeliswa sokuqhafaza izinqubo zebhizinisi ezenzeka

On indlela IDEF0

Indlela Yokwenza IDEF0 kabanzi sibonga elula futhi ecacile ukuze uqonde notation sokuqhafaza, asebenzisa ukwakha imodeli Kuyinto elula kakhulu. Indawo eyinhloko kule indlela kunikezwa imidvwebo. Umdwebo bamele weJiyomethri uhlelo umsebenzi by iinkwere, nokuxhumana etholakalayo phakathi kwemisebenzi kanye imvelo bangaphandle. Izixhumanisi ziboniswa esebenzisa imicibisholo. Lokhu kungabonakala, ubone ukuthi linikeza IDEF0 umdwebo, izibonelo zazo zingatholakala kulesi sihloko.

Iqiniso ukuthi ukumodeliswa wasebenzisa imifanekiso emibili kuphela primitives, ukuvumela ngokushesha ngokwanele ukuchaza imithetho zamanje ekusebenzisaneni IDEF0 labo bantu abangenalo umqondo ngalokhu uhlobo imidvwebo. Ngokusebenzisa imidvwebo IDEF0 ukuxhuma ikhasimende ukuba izinqubo eziqhubekayo washeshe ngaphezulu ngokusebenzisa ulimi ezibukwayo ingcaca. Ungabona enikeza IDEF0 umdwebo, izibonelo zalo ezingenakususwa kukhonjisiwe ngezansi.

Izakhi esetshenziselwa IDEF0

Njengoba sekushiwo, lisetshenziswa 2 izinhlobo primitives Jomethri: amabhokisi nemicibisholo. Onxande amelela izinqubo ezithile, imisebenzi, umsebenzi noma imisebenzi ube nezinhloso kanye kuholele kunomphumela ophawulekayo. inqubo Ukuxhumana phakathi ngokwayo futhi imvelo bangaphandle kuboniswa imicibisholo. Ngo IDEF0 ukuhlukanisa izinhlobo ezinhlanu ezahlukene imicibisholo.

• Ngemvume. Libhekisela yezinto ezibonakalayo noma izikhundla ulwazi kuzoholela okukhiphayo.
• Ukuphathwa. Abekwe ngokomthetho, idatha zokulawula nokulawula, okuyinto iholwa inqubo ngesikhathi abulawe yayo.
• Phuma. Imininingwane noma impahla ukuthi kuwumphumela umsebenzi ukuthi enze kube nokwenzeka ukuba "kwakuthiwa" uhlole ukuthi libonisa IDEF0 idayagramu. Izibonelo ukuqaliswa izinhlelo ezahlukene model enjalo zingatholakala kule domain yomphakathi.
• Mechanism. Izinsiza ezidingekayo ukuba benze lo msebenzi.
• Call. Ingxenye yomsebenzi, okuyinto eyenziwa yenqubo.

The kungenzeka usebenzisa IDEF0

IDEF0 indlela engasetshenziswa yokusungula aspect obusebenzayo yiluphi uhlelo ulwazi.

• Lichaza yiluphi uhlelo. Ukuze unombono, ungakwazi ukubheka IDEF0 (izibonelo amashadi eziye zaba abanye abantu).
• Lichaza noma iyiphi indawo sangaphandle yiluphi uhlelo, ngisho nangaphambi nokubhalwa izidingo sokugcina. Ngesinye uhlelo kanye nendawo yazo kungenziwa eyenziwe ngisho nangaphambi isethulo kuyoba ngaye incarnation wakhe.

Izinhlobo izixhumanisi phakathi izinqubo IDEF0

Ukuze kugcinwe imodeli ukudala izixhumanisi elinjalo eyakhelwe nezokuxhumana zangaphakathi zazibangela ngangokunokwenzeka, futhi yangaphandle - njengendlela ababuthakathaka kungenzeka. Lena ohlangothini okunamandla ukumodeliswa usebenzisa IDEF0. Izibonelo ishadi ungabona ngokwakho futhi ukuqiniseka ngokuthi la mazwi ayiqiniso. Ukuze iwenze ube lula ukusungulwa ukuxhumana anjalo uxhumeke kwi-amamojuli. Phakathi amamojuli efakwe uxhumano zangaphandle, futhi amamojuli ngaphakathi - yangaphakathi. Kunezinhlobo eziningana ukuxhumana.

1. phezulu ( "ingxenye" - "yonke") uxhumano.

2. Ukuphathwa (zokulawula, ongaphansi):

1) ngqo nokuphathwa uxhumano;

2) ukulawula impendulo.

3. Functional noma inqubo:

1) okokufaka ngqo;

2) yokufaka ephambene.

3) umthengi;

4) logic;

5) noma kontanga methodological;

6) umthombo;

7) ulwazi;

8) isikhathi;

9) okungahleliwe.

Amabhlogo wokwakha kanye izixhumanisi amashadi

IDEF0 indlela inikeza eziningi imithetho nezincomo ngokusetshenziswa kwayo futhi ngcono ikhwalithi ukusetshenziswa. Ngokwesibonelo, e ishadi omunye ubonisa block lapho ungacacisa igama uhlelo, injongo yalo. Ukuze uvimbele noma block kuholela imicibisholo 2-5. Ungakwazi ucishe, izandla kodwa okungenani ezimbili ayadingeka entry / ophumayo, kanti bonke abanye senze umsebenzi owengeziwe nesiqondiso kulombhalo. Uma Bhalobhasha ingaphezu 5, kufanele ucabange mayelana nomklamo kahle le imodeli, uma ungakwazi ukwenza kube enemininingwane nakakhulu.

Emabhuloki ekwakha ku imidvwebo yokubola

Isibalo emabhuloki kuyoba kugrafu efanayo, kutuswa kunombolo 3-6. Uma kunjalo kancane, lezi amashadi cishe baphathe incazelo. Uma inani amabhlogo kuyoba omkhulu, bese ufunda idayagramu ezinjalo kungaba nzima kakhulu, uma kucatshangelwa ukutholakala imicibisholo ezingasho. Ukuze uthuthukise yokwamukela ulwazi amabhlogo Kunconywa ukubeka phezulu kuya phansi kanye kwesokunxele kuya kwesokudla. Leli lungiselelo kuzovumela ukubonakalisa logic of the ekwenzeni izinqubo. Kanye umcibisholo kuzodala ukudideka kancane, kokuba inombolo okungenani ezimpambanweni nomunye.

Uma uphelelwa umsebenzi othile kungalawulwa, futhi inqubo iqalwe nganoma yisiphi isikhathi, lesi simo limelela kungekho imicibisholo, okusho ukuphathwa kanye input. Kodwa khona Esimweni esinjalo ongakhuluma abalingani engaba mayelana ukuntengantenga ezithile kanye nesidingo ukuthatha sihlolisise umlingani ezingaba khona.

Iyunithi, esesikhundleni emnyango kuphela umcibisholo kubonisa ukuthi inqubo uthola imingcele okokufaka, kodwa abaphathi kanye ukulungiswa ngeke kwenzeke phakathi kokusebenzisa. Iyunithi, okuyinto kunesikebhe ukulawula umcibisholo isetshenziswa ubheke imisebenzi, okuyinto ngobudedengu oda olukhethekile uhlelo lokulawula. Basuke elawulwa futhi kushintshwe yonke ezigabeni.

Kodwa isibonelo ukwakhiwa imidvwebo IDEF0 yizwa ukuthi eziphelele kakhulu uhlobo female idayagramu ngemicibisholo nokulawula okokufaka.

lokuphakamisa

Ukuze uthuthukise okuqonda sibonwa block ngamunye nomcibisholo ngamunye kufanele igama lalo, ukuthi kuzovumela ukuthi azozibona phakathi sebuningini nezinye amabhulokhi nemicibisholo. Ngakho sibheke izibonelo IDEF0 imidvwebo. uhlelo Imininingwane, wakha ngosizo kubo, kuzokuvumela ukuba baqonde yonke amaphutha nokuba yinkimbinkimbi imodeli.

uhlangane imicibisholo avame ukusetshenziswa, futhi kukhona imibuzo mayelana yokuqamba yabo. Kodwa ekubumbaneni kungenzeka kuphela uma ukudluliswa kwedatha eyohlobo, ngakho abanye amagama akuzona kudingekile, nakuba uhlelo BPWin kungenziwa isethwe. Futhi, uma kukhona ukungahambisani phakathi imicibisholo, zingaba amathuluzi ngokwehlukene igama, ukuqonda ukuthi yini emenza ukuthi.

Uma igatsha ayikho lapha, kodwa kukholakala ukuthi igama ncamashi njengoba kwakunjalo ngaphambili ekhelini. Ngakho-ke kungaba, uma amayunithi ezimbili ezidinga ulwazi olufanayo. Yokuqukethwe idayagramu IDEF0, isibonelo lapho kungatholakala kulesi sihloko, uqinisekise lezi mazwi.

Ulwazi imicibisholo

Imicibisholo engena futhi owayephuma kusuka one block eshadini ukwakhiwa Ukwakheka liboniswe kwalo. Amagama zeJiyomethri, yayiswa umdwebo kufanele ibe kahle ulwazi olufanayo ephezulu ezingeni. Uma imicibisholo amabili kukhona parallel isihlobo komunye nomunye lwesikhathi (ie, on the esengozini ukuqala inqubo kanye ekupheleni kokubili ebusweni omunye enye inqubo), kungenzeka ukuba nokwandisa kubo okumelwe uzihlanganise futhi uthole ofanele imodeli igama uboniswa esihle IDEF0 (imidvwebo izibonelo Visio zingatholakala).

Isibonelo ukuqaliswa kwe-IDEF0 indlela ku lolutsite

Zonke ulwazi imithetho, iziqondiso kanye izici zokwakha beziyoba kube kuqondile ababuthakathaka oyifunayo ngaphandle kokunikeza izibonelo ezingokoqobo ukuqaliswa kwe-IDEF0 indlela.

Usuvele sathola ukuthi kungakanani esikwazi IDEF0 umdwebo, izibonelo kanye nemithetho maqondana nokwakhiwa imidvwebo enjalo kubonakala ingxenye. Manje kubalulekile ukubhekana kokubili umkhuba. Ukuze uqonde kangcono incazelo ngeke siqhubeke eminye imodeli "jikelele", futhi isibonelo esikhethekile, okuyokwenza kangcono futhi baqonde ngokugcwele imininingwane ukusebenza IDEF0 ohlelweni BPWin.

Njengoba isibonelo, ukuletha ukusuka endaweni A isivinini izitimela ukuze ukhombe B. Kuyadingeka ukuba acabangele ukuthi isitimela ongafinyelela ngesivinini engaphezu kuka athathwe njengoba kuvunyelwe. Lokhu ubuso isethwe ngesisekelo isipiliyoni tekusebenta nethonya ukwakheka ku ujantshi wesitimela. Kufanele kuqondwe ukuthi injongo ukwakheka kuyinto ukulethwa abagibeli owavele, ikhokhelwa zokuphepha nenduduzo ukuze uthole lapho uya khona. Ngilusizo IDEF0 umdwebo, izibonelo zazo zingatholakala kulesi sihloko.

Ulwazi kokuqala:

1. pro izindlela umugqa idatha;
2. Iphasiphothi yase-kulo lonke uhlanga;
3. uhambo uhlelo.

idatha Control:

1. Phawula Chief, Shona Yesevisi izindlela.
2. Ulwazi mayelana ukugeleza samanje ukuhamba izitimela.
3. Ulwazi mayelana ukulungiswa kuhlelwe, ekwakhiweni kabusha izindlela ezishintshayo.

Umphumela we-oyisibonelo sithi:

1. Linganisa velocities zivumelekile, ekhombisa izizathu izivimbelo.
2. isivinini Esamukeleka uma ushayela ezindimeni ehlukile futhi izingoma Ukudlalwa.

Lapho kwakhiwa umongo umdwebo, kufanele kunikelwe umfundi bese usethe idayagramu esiyinhlanganisela okuyinto idayagramu ezingeni lokuqala. Kuzoboniswa zonke Imisebenzi esemqoka ohlelweni. Of IDEF0 indlela futhi ishadi, ngokuba yikuphi esibolile, ngokuthi umzali. IDEF0 noqhekeko ibizwa ngokuthi inkampani.

isiphetho

Ngemva noqhekeko wenziwa ezingeni noqhekeko lokuqala ezingeni lesibili - ngakho kuze kube yilesi sikhathi, kuze noqhekeko olwengeziwe akaphelelwa nencazelo yalo. Konke lokhu kwenziwa ukuze bathole enemininingwane kakhulu ihluzo izifunda okwenzeka nezinqubo okuhleliwe. Kuyinto isibonelo elungele IDEF0 imidvwebo, okuyinto ungakwazi ukuzulazula manje.
