Аннотация
Murakkab muhandislik sirtlarini modellashtirishda geometrik aniqlik, sirt uzluksizligi va interaktiv tasvirlash tezligini bir vaqtning oʻzida boshqarish muammosi toʻliq hal etilmagan. Maqsad — parametrik koordinatalar, uzluksizlik nazorati va koʻrish transformatsiyasini yagona hisoblash sxemasiga birlashtiradigan intellektual usulni ishlab chiqish hamda uning samaradorligini anʼanaviy parametrik yondashuv bilan qiyoslash. Metodlar — eksperimental-qiyosiy muhandislik tadqiqoti, algoritmik tahlil, tizim loyihalash, dasturiy sinovlar va tavsifiy samaradorlik oʻlchovlari qoʻllandi. Tanlanma N = 24 boʻlib, intellektual parametrik usul 12 (50 %) va anʼanaviy parametrik usul 12 (50 %) holatda sinovdan oʻtkazildi. Modellashtirish vaqti M = 55,96 daqiqa, SD = 14,44, oraliq 38–75; geometrik xatolik M = 0,32 mm, SD = 0,13, oraliq 0,15–0,51; vizuallashtirish kadr tezligi M = 46 fps, SD = 13,36, oraliq 29–62 boʻldi. Ekspert bahosi 5 ballik shkala boʻyicha M = 4,03, SD = 0,68, oraliq 3,1–4,9 ni tashkil etdi. Intellektual usul modellashtirish vaqtini 39,1 % ga, geometrik xatolikni 56,4 % ga kamaytirdi, kadr tezligini 78,1 % ga oshirdi va ekspert bahosida 1,3 ball farq hosil qildi. Xulosa — taklif etilgan sxema aniqlik va vizual unumdorlikni birgalikda boshqaradi. Ilmiy hissa parametrik diskretlashtirish, sirt uzluksizligi va koʻrish transformatsiyasini yagona baholash mezonida bogʻlashdan iborat.
