Uma uzwa 'u-Payne no-Dolan', abantu abaningi emdlalweni wokwakha umgwaqo ngokushesha bacabanga ngosonkontileka omkhulu wase-Wisconsin, lowo osebenzisa amakhulukhulu amaloli. Ngokuvamile ababonwa njengabakhi bemishini. Yilapho ingxoxo iba mnandi khona. Okusha kwangempela akukona mayelana nokusungula isitshalo esisha kusukela ekuqaleni. Kumayelana nendlela yabo yokulungisa, ukucacisa, kanye nokuhlanganisa amasistimu ukuze uxazulule izinkinga zokukhiqiza ezinevolumu ephezulu oyiqonda kuphela ngemva kokubeka izigidi zamathani. Kungumqondo osebenzayo, ocishe ungabi nazwelo, wobunjiniyela osetshenziswa emishinini ekhona.
Umbono Oyiphutha Womklamo Wangaphakathi
Ake sikusule lokhu kuqala. U-Payne no-Dolan abazakhi izixube zabo zemigqomo noma izindlu zezikhwama esitolo esiyimfihlo. Ukuqamba kwabo okusha kukucaciswe kanye nokulungiswa. Basebenza nabakhiqizi abasunguliwe, kodwa beza etafuleni nohlu lwezidingo ezizalwa ngenxa yeqiniso elinonya, eliphezulu. Akukhona ngezici ezinhle; imayelana nokuqeda iphuzu ngalinye lokwehluleka okungavala ukusebenza okungamathani angama-600 ngehora. Ngizibonile izitshalo zabo, futhi umehluko usemininingwaneni—njengendlela abaqinisa ngayo amaphoyinti okulayisha kumafreyimu okuthutha noma bacacise izinga elithile lensimbi ekwazi ukumelana nemihuzuko yendiza wonke umuntu ayibheka njengejwayelekile.
Yilapho abafana abaningi abathengisa izinto zokusebenza bekuthola kungalungile. Bafaka iphakheji yakamuva ye-automation. Kepha ngomsebenzi onjalo, ukuqanjwa kabusha kuvame ukushoda ngomshini, hhayi isoftware kuphela. Angase agijime amabili aphelele isitshalo se-asphalt lawula amasistimu ngokuhambisana, ikhophi yasenqolobaneni eyisisekelo neshisayo, ngoba iphutha lesofthiwe ngesikhathi sokuthululwa komgwaqo omkhulu wesifundazwe kuba yinhlekelele ngokwezezimali. Lokho akukho kunoma iyiphi incwajana evamile.
Ngikhumbula iphrojekthi lapho bagcizelela khona uhlelo lokulayishwa kwamaloli olwakhiwe ngokwezifiso. Kwakungasheshi ephepheni, kodwa kwaqeda isenzo esithile sokugunda ekuhlanganiseni okwabangela ukuhlukaniswa kwemiklamo ethile yokuxutshwa. Bahlonze inkinga iningi lethu esisanda kuhlala nayo bese bayilungisa. Lona umdlalo wabo.
I-Case in Point: I-Fuel Flexibility Obsession
Emaphakathi nentshonalanga, ukutholakala kukaphethiloli kanye nezindleko zingashintshashintsha kakhulu. Isitshalo esijwayelekile singalungiselelwa igesi yemvelo noma amafutha angu-2. Ukusetha kwe-Payne ne-Dolan kuvame ukwakhelwa ukuguquguquka kokugcina kukaphethiloli. Sikhuluma ngamasistimu angashintsha kalula phakathi kwegesi yemvelo, uwoyela osindayo, ngisho nokumosha uwoyela noma izinhlawulo ze-asphalt binder (RAP) njengesithasiselo sikaphethiloli, ngezinye izikhathi phakathi nosuku olulodwa lokukhiqiza.
Lokhu akukona nje ukwengeza isishisi esengeziwe. Kuwukuhlanganiswa okuphelele kokuphatha uphethiloli, ukushisisa kwangaphambili, ukuhlunga, kanye nokuphathwa komshini wokushisisa. I isitshalo sokuxuba i-asphalt isistimu yokulawula kufanele ilinganise kabusha izilinganiso zomoya kuya kuphethiloli, amazinga okushisa, nezingcindezi endizeni ngaphandle kokuthinta ikhwalithi yokuhlanganisa. Ngike ngezwa ngabo besebenzisana nomkhiqizi wezimbawula ukuthuthukisa idizayini ye-nozzle yokuphathelene ephatha izinguquko ze-viscosity kangcono, inciphisa ukwakheka kwekhabhoni. Baphatha uphethiloli njengento eguquguqukayo, hhayi izindleko ezingaguquki.
Ububi? Inkimbinkimbi. Lezi zinhlelo zidinga omakhenikha abayingxenye kagesi, ingxenye yekhemistri. Kuyi-high-barrier emisha. Usonkontileka omncane angaminza ekulungisweni. Kepha ngesilinganiso sabo, izindleko ezinkulu zibuyela emuva ezinyangeni lapho izimakethe zikaphethiloli zishintsha.
I-RAP Integration Benchmark
Uma kunendawo eyodwa lapho ithonya labo libonakala kakhulu, kusekusetshenzisweni kwephesenti eliphezulu le-Recycled Asphalt Pavement (RAP). Ekuqaleni, badlula imingcele. Ukwenza okujwayelekile komkhakha kungenzeka kube yi-RAP engu-15-20%. Babehlose u-40%, 50%, ngisho nangaphezulu ngaphandle kokuyekethisa ukusebenza. Ukuqanjwa okusha bekusenqubweni yokomisa nokushisisa.
Basuka ekuveleni bajove iRAP phakathi nesigubhu. Ukucaciswa kwabo kuvame ukubiza isomisi se-RAP esizinikele, esihlukile noma isistimu yezigubhu ezimbili eklanywe kakhulu. Umgomo uwukushisa into ebuyisiwe ngobumnene nangokufana ukuze kuxoshwe umswakama ngaphandle kokushiswa kwe-binder endala ebalulekile. Lokhu kudinga izindawo ezinembile zokulawula izinga lokushisa, okuthile izitshalo eziningi ezingekho eshalofini ezinganikezi. Izitshalo zabo aziphathi i-RAP njengesigcwalisi esishibhile, kodwa njengengxenye enembayo edinga umugqa wayo wokukhiqiza olungiselelwe ngaphakathi kwesitshalo esikhulu.
Lokhu kucabanga kwehlile. Manje ubona abakhiqizi abaningi abanikeza amaphakheji e-RAP ephezulu. Kepha umsuka walokho kuphusha, okungenani emkhakheni wevolumu ephezulu, imvamisa isukela kosonkontileka abafana nabo okufakazela ukuthi kungenziwa ngokwethembeka ngezinga elikhulu. Kwashintsha umnotho wayo yonke imboni.
Ukufunda Ku-Supply Chain: Isibonelo se-Yueshou
Awukwazi ukukhuluma ngokuvela kwezitshalo ngaphandle kokubheka i-global supply chain. Osonkontileka abakhulu abakhi zonke izingxenye; bathola okungcono kakhulu. Inkampani efana I-Taian Yueshou Mixing Equipment Co., Ltd. (https://www.taysmix.com) uyisibonelo esihle kakhulu sohlobo lomkhiqizi ozibandakanya kulesi sikhala. Isungulwe ngeminyaka yawo-1990 futhi isebenza endaweni enkulu engu-110,000 sq.m. eShandong, eChina, banesilinganiso sokukhiqiza izingxenye ezinkulu—njengamaqoqo ahlanganisa izigubhu eziphelele noma izisele ezinkulu—ngezimfuneko ezifunwa osonkontileka abakhulu namafemu onjiniyela.
Ukugeleza kokusungula akuyona indlela eyodwa. Usonkontileka ofana no-Payne no-Dolan unenkinga: yithi, ukuguga ngokweqile kuma-paddles okuxuba uma usebenzisa ama-aggregate abi kakhulu. Bazosebenza nethimba labo lonjiniyela kanye nomkhiqizi ofana no-Yueshou ukuze bafanise i-paddle geometry entsha noma into ehlukile yokumbondelana yokushisela. I-Yueshou, enendawo enkulu yokukhiqiza kanye nabasebenzi, ingakha, ihlole futhi iphindaphinde. Ingxenye ewumphumela ingase ibe inketho evamile kukhathalogi ye-Yueshou kwamanye amakhasimende. Usonkontileka uthola isisombululo, umenzi uthuthukisa umugqa womkhiqizo wakhe. Iwuhlobo lwe-Symbiotic, olusebenzayo lwe-R&D.
Yingakho nje ukubheka izinto ezintsha zikasonkontileka ngokuzihlukanisa kudukisa. Inethiwekhi. Okusha kwangempela wuhlelo lwemvelo lokuhlonza izinkinga, ukucaciswa, kanye nokwakhiwa komhlaba wonke abafunde ukuzulazula kuzo.
I-Hidden Innovation: Logistics and Control
Indawo enganakwa kakhulu ukuhlelwa kwezitshalo nokulawulwa kwedatha. Kusonkontileka wezitshalo eziningi, ukuqanjwa kabusha kusekuthunyelwe nasekulandeleni umkhondo. Batshale izimali ezinhlelweni ezihamba ngaphezu kokulandela umkhondo wamaloli. Sikhuluma ngamathegi e-RFID kuwo wonke amaloli, ahlanganiswe nezilawuli zeqoqo lesitshalo kanye ne-telematics yokuvula iphrojekthi.
I isitshalo se-asphalt ayikhiqizi nje ingxube eshisayo; ikhiqiza iphakethe ledatha elinawo wonke ama-batch—i-ID yokuklama hlanganisa, isikhathi sokukhiqiza, izinga lokushisa, i-ID yeloli, iphrojekthi yendawo, ngisho nesikhathi sokuhamba esilinganiselwe ngokusekelwe kuthrafikhi yesikhathi sangempela. Umsebenzisi we-paver angabona iloli ngqo kanye nengxube eza kuye. Leli zinga lokuhlanganisa livimbela ukulahlwa okungalungile, livumela ukukhiqizwa okufika ngesikhathi, futhi lidale irekhodi lekhwalithi elingaguquleki. Iguqula isitshalo sisuke esiqhingini sokukhiqiza sibe indawo ezungezile ohlelweni lokwakha olunenethiwekhi ngokugcwele.
Ukuthuthukisa lokhu kwakungeyona into ekhazimulayo. Kubandakanye iminyaka yokubambana nesoftware engahambelani evela kubakhiqizi bezitshalo, ama-OEMs wamaloli, kanye nabenzi bemishini yokugandaya. Ukuqamba okusha kwaba ukuphikelela ngenkani kokubenza bakhulume bonke, ngokuvamile bebhala i-custom middleware. Inkokhelo iwukuncishiswa kwemfucuza efinyelela iphuzu elibalulekile. Kungukuqamba okusha okuthulile, okusekelwe ku-software okungangabazeki ukuthi kubaluleke kakhulu kunanoma yiluphi ucezu lwensimbi olusha.
Ngakho-ke, Liyini Ifa Langempela?
Ukubuza mayelana noPayne noDolan emisha plant asphalt uyabuza ngempela ukuthi usonkontileka osezingeni eliphezulu uyilolonga kanjani imakethe yemishini. Abawakhiphi amamodeli amasha. Bakha izindinganiso ezintsha. Ifa labo liyisethi yokulindelwe okuphakeme: ukuguquguquka kukaphethiloli, amandla e-RAP, ukuqina kwemishini, kanye nokuhlanganiswa kwedijithali.
Abakhiqizi manje baklama izitshalo benala makhono engqondweni ngoba imakethe ikulindele lokho. I-P&D spec isiphenduke isifinyezo sezinhlelo ezakhiwe ngokweqile, ezithembeke kakhulu, nezididiyelwe ngokujulile. Iphushele yonke imboni kumadizayini aqinile. Ingabe konke ukuhlola kube yimpumelelo? Akunjalo neze. Ngizwile izindaba zezinhlelo eziyinkimbinkimbi kakhulu ezakhishwa kamuva. Kepha lokho kuyimvelo yokuqamba okusha komhlaba wangempela-uyazama, uyehluleka, uyafunda, uyavumelana.
Ekugcineni, ukusungula kwabo okukhulu kungase kufakazele ukuthi izwi likasonkontileka libalulekile ekwakhiweni kwemishini. Kuyingxoxo esebenzayo, exazulula izinkinga eyisa ubuchwepheshe phambili, ikhanda elilodwa elixazululiwe ngesikhathi. Ukweqa okukhulu okulandelayo ekwakhiweni kwezitshalo ngeke kuqhamuke kumdwebo weshidi elihlanzekile ehhovisi likanjiniyela; izovela engxoxweni ku-trailer yomsebenzi eduze kwesitshalo esisebenza ngo-24/7 inyanga yonke, ithola ukuthi yini ezophuka ngokulandelayo nokuthi ungayimisa kanjani.
