Kupanga kwa UOE ndi JCOE, kusiyanitsa kwazinthu zosiyanasiyana

Kawonedwe kuchokera ku njira ziwiri zopangira, zonse popanga kutsogolo ndi kumbuyo ndizofanana, kusiyana kwakukulu ndikuti njira yowumba.Kupanga kwa UOE kumakhala ndi masitepe awiri: U kupanga ndi O kuumba.Ndipo JCOE yomwe imapanga gawo la pulogalamuyi imagawidwa m'magawo asanu ndi limodzi, kupanga bwino kumachepetsedwa kwambiri.Kupanga njira zosiyanasiyana, zomwe zimatsogolera ku kusiyana kwa UOE ndi JCOE m'mimba mwake, makulidwe a khoma, miyeso, magwiridwe antchito, kuchuluka kwa zokolola.

Chitoliro cha mzere wa UOE ndi JCOE wa chitoliro cha mapaipi kuchokera pakuwunika koyerekeza kwa njira yopangira ndi mtengo wopangira, mfundo zotsatirazi:

(1) UOE kupanga dzuwa, mphamvu, ndi m'malo nkhungu nthawi yaitali, oyenera kupanga

(1) UOE kupanga dzuwa, mphamvu, ndi m'malo nkhungu nthawi yaitali, oyenera kupanga zedi lalikulu, mankhwala a specifications limodzi;kupanga JCOE yocheperako, nkhungu yofananira ndi mafotokozedwe osiyanasiyana, oyenera kupanga voliyumu yaying'ono, zinthu zamitundu yambiri.

(2) ndi UOE kupanga mankhwala m'mimba mwake osiyanasiyana osiyanasiyana makulidwe ayenera kukhala zosakwana JCOE, koma mokwanira kukwaniritsa zofunika za polojekiti.

(3) Kuchokera pamawonedwe a magwiridwe antchito, chitoliro cha mzere wa UOE poyerekeza ndi JCOE omwe ali ndi nkhawa yotsalira, Miyeso yolondola kwambiri imabweretsa zabwino kuposa zazing'ono.
