Kugadzirisa Kunofambiswa Nedata uye Kugadzirisa Zvinofanotaurwa
Remangwana reWFGDKudzora maitiro kuri kupfuura nzira dzechinyakare dzekugadzirisa zvinhu. Kuyerera kuri kuramba kuchienderera mberi kwedata remhando yepamusoro kubva kumamita ehuwandu hwemadhijitari epamhepo nemamwe masensa kunopa hwaro hwemafuremu anotungamirwa nedata anoshandisa kudzidza kwemuchina uye njere dzekugadzira. Aya mamodheru epamusoro anogona kugamuchira huwandu hwakawanda hwedata rekare uye renguva chaiyo kuti aone maparamita ekushanda akakodzera pasi pemamiriro akasiyana-siyana, akadai sekuchinja kwemagetsi emarasha kana mitoro yakasiyana-siyana yemayuniti.
Maitiro aya epamusoro anomiririra shanduko huru muhuzivi hwekushanda. Pane kungopindura kune maalamu anoratidza kuti parameter haisi pane yakatarwa, masisitimu aya anogona kufanotaura kutanga kwedambudziko uye kugadzirisa parameters nekukurumidza kuti ridzivise. Chinangwa chikuru chemamodeli aya ndechekugadzirisa zvinangwa zvakawanda, dzimwe nguva zvinopesana, panguva imwe chete, zvakaita sekuderedzamaitiro ekubvisa sulfurizationmutengo uye kuderedzaSO₂Nekuramba uchiongorora "minwe" yedata rekushanda kwechirimwa, kusanganisira huwandu hwevanhu, masisitimu aya anogona kugara achiwana mwero wepamusoro wekuchengetedza uye kushanda zvakanaka kwehupfumi.
