Izi zimathandiza woyang'anira zombo kuzindikira ngati zomwe zilipo panopa zikugwira ntchito mopitirira muyeso kapena mochepera zomwe zikuyembekezeredwa, ndikupanga zisankho zokhudzana ndi data yokhudza kukweza kapena kusintha giredi ya GET. Ndikupangira pulogalamu yowunikira nthawi yogwiritsidwa ntchito pa ntchito zonse za zombo za m'migodi.
Pulogalamu yowunikira yomwe ndikupangira imatsata miyezo yotsatirayi ya seti iliyonse ya GET yomwe yayikidwa pa makina aliwonse: tsiku lokhazikitsa ndi maola ogwirira ntchito pokhazikitsa; masiku owunikira ndi maola ogwirira ntchito poyesa kulikonse; kulemera kwa nsonga pakukhazikitsa (koyesedwa pa sikelo yolinganizidwa musanayike); kulemera kwa nsonga pakuyesa kulikonse (koyesedwa mwanjira yomweyo); chifukwa chochotsera (chosweka, chosweka, chotayika, chosinthidwa nthawi yokonzedweratu); maola ogwirira ntchito pochotsa; ndi matani azinthu zomwe zasunthidwa panthawi ya moyo wa seti ya GET (kuchokera ku zolemba zopangira). Kuchokera ku deta iyi, ma KPI otsatirawa amatha kuwerengedwa: maola pa seti iliyonse ya nsonga (nthawi yovalira), matani pa seti iliyonse ya nsonga (nthawi yovalira yosinthidwa ndi kupanga), mtengo pa ola limodzi logwirira ntchito, ndi mtengo pa tani yazinthu zomwe zasunthidwa. Ma KPI awa amatha kuyerekezeredwa pakati pa makina, pakati pa madera a miyala, pakati pa nyengo, ndi pakati pa magiredi a GET kuti adziwe zomwe zili zoyenera pa ntchito iliyonse yeniyeni.
Ndakhazikitsa pulogalamu yowerengera ndalama kwa makasitomala angapo a sitima zapamadzi, ndipo detayi ikuwonetsa kusintha kwakukulu kwa magwiridwe antchito a GET m'sitima yonse yomwe sikufotokozedwa ndi kusiyana kwa zinthu zokha. Pankhani ina, tinapeza kuti dozer imodzi inali kupeza nthawi yochepera theka ya moyo wa makina ofanana omwe amagwira ntchito m'dera lomwelo la migodi, zomwe kafukufuku adawonetsa kuti zidachitika chifukwa cha kukhazikika kolakwika kwa ngodya ya chidebe komwe kunkapangitsa kuti GET ikwapule m'malo modula zinthuzo. Kukonza ngodya ya chidebe (kusintha kopanda mtengo) kunapangitsa kuti moyo wa GET ukhale wovalidwa ndi 60% ndikuchepetsa mtengo wa GET pa tani ndi 35% - zonse kuchokera pakukonzanso machitidwe okonza komwe kudadziwika kokha kudzera mu kuwerengera moyo wa kuvala mwadongosolo.
Mtengo Wonse wa Kusanthula kwa Eni ake pa Zisankho za GET Specification
Njira yolondola yoyerekeza zofunikira zosiyanasiyana za GET ndi kusanthula mtengo wonse wa umwini (TCO) komwe kumawerengera zigawo zonse za mtengo panthawi yowunikira, osati mtengo woyamba wa zigawo zokha. Ndikupangira kusanthula kwa TCO ndi zigawo zotsatirazi, zowerengedwa pamlingo wa tani imodzi ya zinthu zomwe zasunthidwa: Mtengo wa gawo la GET (kuphatikiza ma tips, ma adapter, ndi zida zilizonse zosungira); mtengo wa ntchito ya GET (kuphatikiza kuchuluka kwa ntchito zamakanika, maola pakusintha, ndi kuchuluka kwa kusintha pa nthawi iliyonse); mtengo wa nthawi yopuma ya zida (kuphatikiza kutayika kwa kupanga panthawi yosintha kwa GET, komwe kumawerengedwa pa ndalama zochepa pa tani imodzi ya zinthu zomwe zasunthidwa); mtengo wokhudza kupanga (kuchepa kwa magwiridwe antchito a dozer panthawi yomwe GET yavalidwa koma sinasinthidwebe, yomwe imawerengedwa pogwiritsa ntchito kusiyana pakati pa kakulidwe ka magwiridwe antchito ka GET yovalidwa ndi yatsopano); ndi mtengo wachiwiri wowonongeka (kukonzanso kulikonse kwa kapangidwe ka tsamba komwe kumachitika chifukwa cha GET yovalidwa, yochepetsedwa panthawi yowunikira).
Kusanthula koyenera kwa TCO nthawi zambiri kumavumbula kuti kufotokozera mtengo wotsika kwambiri kwa GET ndi kokwera mtengo kwambiri pamaziko a TCO, ndipo mosemphanitsa. Mu kusanthula kwina kwa malo osungira miyala yamwala omwe amagwiritsa ntchito ma bulldozer anayi, ndinayerekeza GET yachitsulo yokonzedwa bwino (USD 180 pa seti iliyonse, moyo wovala maola 300) ndi GET yapamwamba kwambiri ya chrome carbide overlay (USD 380 pa seti iliyonse, moyo wovala maola 550). Mtengo wa GET mwachindunji pa ola limodzi unali USD 0.60 pa muyezo poyerekeza ndi USD 0.69 pa mtengo wapamwamba - mtengo wapamwamba unali wokwera kwambiri pamtengo mwachindunji. Koma pamene zotsatira za kupanga ndi kuwonongeka kwachiwiri zinaphatikizidwa, GET wamba unali ndi TCO ya USD 2.40 pa ola limodzi logwira ntchito pomwe GET yapamwamba inali ndi TCO ya USD 1.85 pa ola limodzi logwira ntchito - phindu la 23% la TCO pa kufotokozera mtengo wapamwamba ngakhale kuti mtengo wake woyamba unali wapamwamba.
