持份者未必愿意與其他各方共享數(shù)據(jù),尤其是較爲(wèi)敏感的數(shù)據(jù)或個人數(shù)據(jù)。因此,需要有一個強(qiáng)而有力的問責(zé)框架(如下所述)來鼓勵數(shù)據(jù)共享,同時為共享數(shù)據(jù)的各方提供足夠程度的保護(hù)。數(shù)據(jù)標(biāo)準(zhǔn)—

缺乏一致的數(shù)據(jù)標(biāo)準(zhǔn)和規(guī)則來收集數(shù)據(jù),導(dǎo)致不同部門難以共享數(shù)據(jù),無法通過協(xié)作創(chuàng)造協(xié)同效益,

及最大化數(shù)據(jù)價值。更新信息—

需要一套系統(tǒng)更新機(jī)制來不斷更新靜態(tài)物件并掃描新出現(xiàn)的物件,以確保與現(xiàn)實(shí)世界對應(yīng)的數(shù)字孿生的準(zhǔn)確性,從而做出準(zhǔn)確的決策。人才競爭

盡管AI等技術(shù)可以用更少的人力資源來做更多的事情,事實(shí)上仍需要大量的專業(yè)人員(例如數(shù)據(jù)科學(xué)家/工程師和建筑師)來梳理海量的信息。Accountable,SecurityandPrivacyDigitalTwinsinSmart

從獲取,充實(shí),維護(hù),使用,歸檔和清除,整個數(shù)據(jù)生命周期必須確保免受惡意行為者和侵犯私隱權(quán)的侵害。問責(zé)制—

缺乏問責(zé)制框架,例如數(shù)據(jù)發(fā)布的開放數(shù)據(jù);與私隱和網(wǎng)絡(luò)安全有關(guān)而不斷更新的法規(guī);

持份者必須對實(shí)施數(shù)字孿生的預(yù)期結(jié)果達(dá)成共識(并適當(dāng)考慮資源限制),并制定一套適當(dāng)?shù)腒PI,以反映數(shù)字孿生將帶來的益處。4.Tailoredimplementationapproach–Thereisno“one-size-fits-all”approachfordigitaltwindevelopment.Thishighlightstheneedforeachcitytocatertolocalcircumstances.ThelocalcontextdrivestheDigitalTwinModels(andmix)andimplementationscheduleofdigitaltwininitiatives.Forinstance,withawidespectrumofpossibilitiesbutlimitedresources,governmentsneedtoprioritiseandmapoutanimplementationplanonturninggreenfieldsitesintosmartdevelopmentswithwell-integratedinfrastructuresandseamlessdeviceconnectivity,orconvertingexistingsitestoenabledigitaltwin

為了確保具有高度安全性和私隱性的豐富的數(shù)據(jù)環(huán)境,需要建立政策和

標(biāo)準(zhǔn),以闡明如何收集,交換,分發(fā)數(shù)據(jù)以及如何分發(fā)和使用信息。創(chuàng)建受信任和受監(jiān)管的流程是建立強(qiáng)大的數(shù)據(jù)環(huán)境的關(guān)鍵,

該環(huán)境將推動數(shù)據(jù)和數(shù)字孿生的使用。4.量身定制的實(shí)施方法—
