    Umuyoboro w'umushumi w'ubwiza bwo hejuru

    Umuyoboro w'umushono w'ubwiza bwo hejuru Ishusho igaragara
    • Umuyoboro w'umushumi w'ubwiza bwo hejuru

    Ibisobanuro bigufi:

    Umuyoboro wacu w’umugozi wo mu rwego rwo hejuru ukwiriye gukoreshwa mu buryo butandukanye, harimo ubwubatsi, peteroli na gaze, ndetse no gutwara abantu mu mazi. Kubera imbaraga zawo zidasanzwe no kuramba, wagenewe kwihanganira igitutu no kurwanya ingese, bigatuma uba igisubizo kirambye ku byo ukeneye mu miyoboro yawe.


    Ibisobanuro birambuye ku gicuruzwa

    Ibirango by'ibicuruzwa

    Tubagezaho umuyoboro wacu wo mu bwoko bwa spiral-seam, ibicuruzwa bigaragaza imbaraga, kuramba no gukora neza. Byakozwe hakoreshejwe uburyo bugezweho bwo gusudira spiral, imiyoboro yacu ikorwa mu byuma bishyushye bikozwe neza mu ishusho y'uruziga kandi bigahuzwa ku muyoboro wo mu bwoko bwa spiral. Ubu buryo bushya bwo gukora ntibutuma imiyoboro irushaho kuba myiza gusa, ahubwo bunatuma ishobora kwihanganira ikoreshwa rigoye cyane.

    Muri sosiyete yacu, twishimira ubwitange bwacu budatezuka mu kunyurwa kw'abakiriya. Mu myaka yashize, twubatse izina ryiza cyane dushyira imbere ibyo abakiriya bacu bakeneye muri buri cyiciro cy'uburyo bwo kugura. Kuva ku nama mbere yo kugurisha kugeza ku bufasha mu kugurisha no gutanga serivisi zirambuye nyuma yo kugurisha, twiyemeje guhaza ibyo abakiriya bacu bakeneye byose. Ubu buryo bwo kwita ku bakiliya bwacu bwatugiriye icyizere n'ubudahemuka bw'abakiriya bacu, bahora bishimira ireme ry'ibicuruzwa byacu n'uburyo serivisi zacu zizewe.

    Ubwiza bwacu bwo hejuruumuyoboro w'umugozi uzungurukaikwiriye gukoreshwa mu buryo butandukanye, harimo ubwubatsi, peteroli na gaze, ndetse no gutwara abantu mu mazi. Kubera imbaraga zayo zidasanzwe no kuramba, yagenewe kwihanganira igitutu no kurwanya ingese, bigatuma iba igisubizo kirambye ku byo ukeneye mu miyoboro yawe.

    Akamaro k'ibicuruzwa

    1. Imwe mu nyungu z'ingenzi z'umuyoboro w'uruziga ni imbaraga zawo nziza cyane. Uburyo bwo gusudira uruziga butuma umuyoboro ukomeza gusudira, bityo bikarushaho kunoza imiterere yawo. Ibi bituma uba mwiza mu gutwara amazi n'imyuka mu gihe ufite umuvuduko mwinshi.

    2. Uburyo bwo gukora bukora neza, butuma imiyoboro miremire ikorwa hatabayeho gukenera imiyoboro, ibyo bikaba bishobora kuba intege nke.

    3. Indi nyungu ikomeye yaumuyoboro w'umugozi wo mu gisengeni uburyo bwo gukora ibintu byinshi. Bishobora gukorwa mu buryo butandukanye bwa diameter n'ubugari bw'inkuta kugira ngo bikoreshwe mu buryo butandukanye kuva ku gutwara peteroli na gaze kugeza ku miyoboro y'amazi.

    4. Amasosiyete akora iyi miyoboro ashyira imbere kunyurwa kw'abakiriya kandi agatanga serivisi zirambuye mbere yo kugurisha, mu gihe cyo kugurisha, na nyuma yo kugurisha. Iyi ntego ireba abakiriya bahabwa ibicuruzwa bijyanye n'ibyo bakeneye byihariye, bigatuma ubunararibonye muri rusange burushaho kwiyongera.

    Ibura ry'ibicuruzwa

    1. Uburyo bwo gusudira bushobora kuba bugoye kurusha uburyo bwa gakondo bwo gusudira, ibyo bikaba byatera ikiguzi cyo gukora kiri hejuru.

    2. Nubwo imiyoboro y'uruziga ikomeye, ishobora kudahangana n'ubwoko bumwe na bumwe bwa ingese kurusha indi miyoboro kandi igasaba gutwikirwa cyangwa kuvurwa.

     

    umuyoboro w'icyuma uzunguruka

     

     

    Ibibazo Bikunze Kubazwa

    Q1: Umuyoboro w'umugozi uzunguruka ni iki?

    Umuyoboro w'umugozi ukozwe hakoreshejwe uburyo bwihariye bwitwa inzira yo gusudira mu buryo bw'umugozi. Ubu buryo bushya bukoresha imigozi y'icyuma ishyushye ikorwa mu buryo bw'umuzenguruko hanyuma igasukwa ku mugozi uzunguruka. Umuyoboro uvamo ntugira imbaraga nyinshi gusa ahubwo unaramba neza, bigatuma uba mwiza mu bikorwa bitandukanye, harimo gutwara peteroli na gaze, gutanga amazi no gushyigikira inyubako.

    Q2: Kuki uhitamo umuyoboro w'umushono w'ubwiza bwo hejuru?

    Akamaro gakomeye k'imiyoboro y'uruziga nziza ni uko ikora neza. Uburyo bwo gusudira uruziga butuma habaho gusudira buri gihe, ibyo byongera ubuziranenge n'ubudahangarwa bw'umuvuduko w'umuyoboro. Byongeye kandi, iyi miyoboro ishobora gukorwa mu bunini butandukanye n'ubunini kugira ngo ihuze n'ibyo imishinga itandukanye ikeneye.

    Q3: Ni iki nkwiye kureba mu mucuruzi?

    Mu gihe uhitamo umucuruzi w’imiyoboro y’uruziga, ni ngombwa guhitamo ikigo gishyira imbere kunyurwa n’abakiriya. Shaka umucuruzi utanga serivisi zirambuye mbere yo kugurisha, kugurisha, na nyuma yo kugurisha. Ikigo cyizewe kizagenzura ko ibicuruzwa byacyo byujuje ibisabwa kandi gishobora kubahiriza ibyo ukeneye byihariye, kikakwemeza ko ubona ibicuruzwa na serivisi byiza abakiriya bawe bazishimira.
