Palibe zida zamakina oyaka moto, okhala ndi mbiya yosakanikirana yofananira. Mitsuko yake yosakanikirana imatha kusakanikirana kwathunthu, nthawi yomweyo, pakusakaniza, imathanso kusakanikirana kofananira ndi zida zapulasitiki kapena zida zouma zouma. Posakaniza, sichingathe kudyetsa mobwerezabwereza. Chifukwa kudyetsa mobwerezabwereza kumatha kuwonjezera katundu wa makina a njerwa osayaka, zomwe zimapangitsa kuti makina azitsekeka kapena phokoso lalikulu. Zoonadi, mutatha kusakaniza bwino kwa chidebe chosakaniza, kusakaniza kwabwino kosalekeza kumafunika. Zachidziwikire, pakatha nthawi yokwanira yosakanikirana, kutulutsa kosinthika kumatha kuchitidwa, ndipo zida zosakanikirana zitha kutumizidwa kwina, kuti muzindikire kuumba kotsatira ndi kutulutsa Njira yakukanikiza. Mwanjira iyi, zida za mphete zimagwira ntchito yayikulu. Sikuti ndi wothandizira wamkulu woyambitsa, komanso chofunikira kwambiri kuti makina azindikire ntchito yaulere.

Kachiwiri, kuchuluka kwa kugwiritsa ntchito zida.

Poganizira kuchuluka kwa kugwiritsa ntchito makina opangira njerwa osawotcha, mwachiwonekere akatswiri apanganso chidule. Akuganiza kuti zida zopangira izi ndizoyenera kugwiritsa ntchito njerwa za mlatho, kapena ntchito zina za njerwa zomanga. Zachidziwikire, mafakitale ena akuluakulu angagwiritsidwenso ntchito, makamaka fakitale ya konkriti imatha kugwiritsa ntchito njerwa izi. Kagwiritsidwe ntchito kake ndi kambiri. Panthawi imodzimodziyo, malo ogulitsa malonda a zinyalala zolimbazi akukulitsidwa mopanda malire.

Chachitatu, ubwino waukulu wa zipangizo.

Monga tonse tikudziwa, makina opangira njerwa ndi zida zapamwamba kwambiri zopangira njerwa. Zida zamtunduwu ndizowoneka bwino kwambiri, zimazindikira mawonekedwe ake, ndipo mawonekedwe ake ndi ochepa. Choncho, tikamagwiritsa ntchito, sizikhala ndi malo akuluakulu, ndipo zimakhala zosavuta kusuntha, choncho zingagwiritsidwe ntchito mobwerezabwereza m'madera ambiri ogwira ntchito. Zachidziwikire, kugwiritsa ntchito zinyalala kwa zida zafika 95%. Panthawi imodzimodziyo, zinthu zosiyanasiyana zowononga zowonongeka zimatha kufananizidwa mwasayansi ndi kuzindikira kusakaniza ndi kupanga kupanikizika kwa mbiya yosakaniza, ndipo potsiriza kupanga njerwa zomwe zimagwiritsidwa ntchito kwambiri pamsika, kotero kuti ntchito yake yogwiritsira ntchito yawonjezeka kwambiri.

Chifukwa ochita kafukufuku adaphunzira momwe makina a njerwa amadzimadzi okha osayaka, mawonekedwe ake ndi omveka komanso osavuta, komanso kukonza kwake ndikosavuta kwambiri. Zoonadi, chochititsa chidwi kwambiri n’chakuti zipangizozi zimakhala zolimba kwambiri zikagwiritsidwa ntchito. Ndi kusintha kwa kupanga bwino, wopanga akhoza kusunga nthawi ndi mphamvu zambiri, motero kumapangitsa kuti phindu likhale lopindulitsa. Zoonadi, kuumba mwachangu komanso kuchitapo kanthu mwachangu kumapangitsa kuti zida zamtunduwu zizidziwika kwambiri pamsika. Opanga ambiri ayamba kugula ndi kuyambitsa zida, zomwe zimathandizira kwambiri pakuwongolera zinyalala zolimba ku China. Tsopano mazana masauzande a matani a zinyalala zolimba sizingakhudze chilengedwe, koma kuyikidwa mukupanga kachiwiri kuti azindikire phindu lachiwiri lazamalonda. Inde, tiyeneranso kutsatira zofunikira zaumisiri ndi chitetezo tikamagwiritsa ntchito zida, kuti tipewe kuwononga zida ndikuwonjezera ndalama zokonzetsera chifukwa chogwiritsa ntchito mwakhungu komanso kusadziwa za taboos, zomwe zimawononganso mabizinesi opanga.
