Pakalipano, mtundu wotchuka kwambiri wa zida zopangira njerwa pamsika ndi makina a njerwa osawotcha, omwe ali ndi mawonekedwe a liwiro lowumba mwachangu komanso mwachangu. Choncho, ambiri opanga njerwa zinyalala anayambitsa mtundu uwu wa makina ndi zipangizo. Malingana ndi zizindikiro zazikulu za zida zamtundu uwu, palinso chidule chotsatirachi chofotokozera.

Choyamba, kayendedwe ka kachitidwe ka chipangizo.Palibe choyaka zida zamakina a njerwa, ndi chidebe chofananira chosakanikirana. Mitsuko yake yosanganikirana imatha kusakanikirana yokha, nthawi yomweyo, ikasakaniza, itha kugwiritsidwanso ntchito pazinthu zina zapulasitiki, kapena zida zowuma zowuma zosakanikirana zofananira. Mukusakaniza, kudyetsa mobwerezabwereza sikuloledwa. Chifukwa kudyetsa mobwerezabwereza kumatha kuwonjezera katundu wamakina osawotcha, zomwe zimapangitsa kuti makina azitsekeka kapena phokoso lalikulu. Zachidziwikire, chidebe chosakanikirana chikasakanizidwa bwino, ndikofunikira kuchita kusakanikirana kopitilira muyeso. Zoonadi, itatha kusakaniza nthawi yokwanira, kutulutsa kosinthika kumatha kuchitika, ndipo zida zosakanikirana zitha kutumizidwa kwina, kuti muzindikire kuumba ndi kutulutsa kotsatiraku. Pochita izi, mphete ya mphete imakhala ndi gawo lalikulu, ndiye wothandizira wamkulu wa kusakaniza, komanso chofunikira kwambiri kuti azindikire kugwira ntchito kwaulere kwa makina.

Kachiwiri, kuchuluka kwa zida zogwiritsira ntchito. Poganizira kukula kwa makina opangira njerwa osawotcha, zikuwonekeratu kuti akatswiri aperekanso chidule. Akuganiza kuti zida zamtunduwu zopangira ndi kukhazikitsa ndizoyenera kugwiritsa ntchito njerwa za milatho ina kapena malo ena omanga. Inde, mafakitale ena akuluakulu angagwiritsidwenso ntchito, makamaka fakitale ya konkire yachigawo ingagwiritse ntchito bwino njerwazi. Kuchuluka kwawo kwa ntchito ndi kwakukulu, ndipo panthawi imodzimodziyo, malonda a zinyalala zolimbazi akukulitsidwa mopanda malire.

Chachitatu, ubwino waukulu wa zipangizo.Monga tonse tikudziwira, makina a njerwa osawotcha ndi zipangizo zamakono zopangira njerwa. Zida zamtunduwu ndizowoneka bwino kwambiri ndipo zimazindikira kapangidwe kake. Panthawi imodzimodziyo, mawonekedwe ake ndi ochepa. Choncho, tikamagwiritsa ntchito, sizidzatenga malo ambiri, panthawi imodzimodziyo, ndi yabwino kusuntha, kotero kuti ingagwiritsidwe ntchito mobwerezabwereza m'madera ambiri ogwira ntchito. Zachidziwikire, kugwiritsa ntchito zida zafika 95%. Pakadali pano, zida zosiyanasiyana zotayira zolimba zitha kufananizidwa mwasayansi kuti zizindikire kupangika ndi kukanikiza kwa chidebe chosakanikirana, ndipo pomaliza njerwa zomwe zingagwiritsidwe ntchito kwambiri pamsika zidzapangidwa. Chifukwa chake, kuchuluka kwa kugwiritsidwa ntchito kwake kwawonjezeka kwambiri.

Chifukwa ochita kafukufuku adaphunzira momwe makina opangira njerwa osawotcha, mawonekedwe ake ndi omveka komanso osavuta, komanso kukonza kwake ndikosavuta kwambiri. Zoonadi, chochititsa chidwi kwambiri ndi chakuti zipangizo zamakono zimakhala zapamwamba kwambiri zikagwiritsidwa ntchito. Kuwongolera bwino kwa kupanga kumapangitsa wopanga kupulumutsa nthawi ndi mphamvu zambiri, motero amawongolera kwambiri malo opindulitsa. Zoonadi, kuumba kumakhala mofulumira ndipo zotsatira zake zimakhala zofulumira, zomwe zimapangitsa kuti msika ukhale wotchuka kwambiri wa zida zamtundu uwu wa njerwa. Opanga ambiri ayamba kugula ndi kuyambitsa zida, zomwe zathandizira kwambiri kuwongolera zinyalala zolimba ku China. Masiku ano, mazana masauzande a matani a zinyalala zolimba sizingakhudze chilengedwe, m'malo mwake, zidzapangidwanso kuti zizindikire kuwonetsera kwachiwiri kwamtengo wapatali. Inde, tiyeneranso kutsata zofunikira zachitetezo chaukadaulo pogwiritsira ntchito zida, kuti tipewe kuwononga zida chifukwa chogwiritsa ntchito mwakhungu zinthu zomwe sizikudziwa kugwiritsa ntchito zida, zomwe zimapangitsa kuti pakhale kuwonjezeka kwa ndalama zokonzetsera, zomwe zimawononganso mabizinesi opanga.
