Ishedyuli Network: Iimbalasane wokwakha

Le grafu womnatha sisixhobo. Nayo kubanjwe ucwangciso kunye nolawulo lomsebenzi. Xa ulawulo lomgangatho xa kusenziwa rhoqo kakhulu wasebenzisa ucwangciso network, okanye itshathi Gantt.

Amaninzi, umzobo womnatha esetyenziswa ukuyila iintlobo ngeentlobo zemisebenzi ezakha iseti yeendidi ezahlukeneyo yezenzo. Ukusetyenziswa kwishedyuli womnatha ukufumanisa imihla xa iprojekthi lugqityiwe, kwaye kunceda ukuchonga amathuba ukunciphisa ixesha lomsebenzi. Oku kuthetha ukuba kumsebenzi womnatha kwishedyuli ye ixesha zihlobene, kwaye oku kukunika ithuba elihle lokuba esweni inkqubela yazo.

Ishedyuli Network kubume bayo - egopheni, encotsheni leyo umi isiganeko (ubume bento okanye umsebenzi ngexesha elithile), kwaye jike ze igrafu (oko kukuthi, ehlanganisa encotsheni ezimbanjeni) zibonisa umsebenzi. Kwenziwa igophe enjalo, inxalenye PERT-ndlela (Inkqubo Evaluation & Review Technique). It yasungulwa ngo-1958 yinkampani yaseMelika, kunye nenjongo yawo yokuqala yaba ukucwangcisa, kwakunye kuvavanyo Injongo inkqubela projekthi.

Ukwakhiwa imizobo womnatha iya kwenziwa ngendlela eyahlukileyo. Kulo mzekelo, encotsheni igrafu - esebenza ngayo, i arc ubonisa ulwalamano olukhoyo phakathi kwabo. Olo khetho lungasetyenziswa ngakumbi, kwaye yinxalenye CMP-ndlela (Critical Indlela Indlela), okanye indlela endleleni ezibalulekileyo.

Inkqubo yokwakha igrafu usebenzisa ezibalulekileyo indlela umendo yenziwa la manyathelo alandelayo:

• Ukuze ubone Iinjongo yesicwangciso.
• Chonga imida ezichaphazela ishedyuli network, ngokunjalo kumsebenzi ocwangcisiweyo.
• Ukumisela ukwakheka lwemisebenzi eziyimfuneko ukuphumeza le njongo.
• Yenza uphawu ubude amakhadi. Oku kukhankanya izixhobo, izibonelelo, nabo bonke onegunya izenzo.
• Ukuqwalaselwa iinjongo kunye nenkcazo into eza kuqala kubulawa.
• Nokwabela imisebenzi ekufuneka yenziwe emva yokuqala.
• Ukubonisa unxibelelwano phakathi imisebenzi. Isetyenziswa kule utolo, ebonisa ukulandelelana izenzo. Ukuze kwakhiwe ucwangciso womnatha, kusetyenziswa ngexesha lethu, umzekelo, inkqubo MS Visio.
• Ukumisela ukuqala kunye wokugqiba umsebenzi ngamnye.
• Ukubekwa ekuqaleni kwexesha nokugqiba kade umsebenzi ngamnye.
• Ingcaciso ixesha yokulinda umsebenzi ngamnye. Oku kubalwa njengokuba umahluko ixesha phakathi kwexesha kwaye nasekuthwaseni yokuqala, kwakunye imisebenzi emva kwexesha neziphelo yokuqala.
• Ukufumanisa indlela apho ixesha somsebenzi ngasinye uvimba ngu zero. Le ndlela kuthiwa ezibalulekileyo.

Ukuba kuyimfuneko, eli ifoun ishedyuli network passes, yaye kuqala umntu kufuneka ukuhlalutya iingxaki sisendleleni ezibalulekileyo.

Ukuba usebenzisa, umzekelo, ukwakhiwa ngomlinganiselo omkhulu kwishedyuli womnatha, ungenza ngokulula ukwakha igrafu inani labasebenzi abaqeshwe, iindleko zomsebenzi, ukuselwa izinto kunye nezigqeba xesha ngalinye. Ezi tshathi kwakhona ukunika ithuba lokuba sabe izibonelelo ukuze ukwandisa ucwangciso womnatha.
