4. Cikakkun Bayanai na Fasaha & Ƙirar Lissafi
Babbar matsala a cikin MEC ita ce cire lissafi. Za a iya tsara ƙirar sauƙaƙa azaman matsala ta rage jinkiri. Yi la'akari da na'urar wayar hannu tare da aiki mai girman $L$ (a cikin bits) yana buƙatar $C$ zagayowar CPU don lissafin.
Jinkirin Ai da Kai na Gida: $T_{local} = \frac{C}{f_{local}}$, inda $f_{local}$ shine mitar CPU na na'urar.
Jinkirin Cirewa na Bakin Ciki: Wannan ya ƙunshi sassa uku:
- Lokacin Watsawa: $T_{tx} = \frac{L}{R}$, inda $R$ shine ƙimar bayanai mai hawa zuwa uwar garken bakin ciki.
- Lokacin Lissafi na Bakin Ciki: $T_{comp} = \frac{C}{f_{edge}}$, inda $f_{edge}$ shine mitar CPU da aka ware na uwar garken.

6. Ayyukan Gaba & Hanyoyin Bincike
Ayyukan da ke Tasowa:

Mahimman Hanyoyin Bincike:
- Tsarin MEC na Asalin AI: Ƙirar tsarin inda AI ba kawai ke gudana a kan bakin ciki ba har ma yana sarrafa kayan aikin bakin ciki da kansa (hanyoyin sadarwa masu inganta kansu).
- Sadarwa na Ma'ana & Lissafi Mai Manufa: Matsawa fiye da watsa bayanai na danye zuwa aika bayanan da ke da alaƙa da ma'ana kawai waɗanda ake buƙata don kammala aiki, yana rage buƙatun bandwidth sosai.
- Koyo na Tarayya a Girma: Haɓaka ƙa'idodi masu inganci don horar da ƙirar AI na duniya a cikin miliyoyin na'urori na bakin ciki iri-iri yayin kiyaye keɓantacce.
- Haɗin kai tare da Hanyoyin Sadarwa na Gaba: Haɗin gwiwar ƙira mai zurfi na MEC tare da fasahohin 6G kamar saman hankali mai sake fasalin (RIS) da sadarwar terahertz.
- Ƙira Mai Dorewa: Ingantaccen tsarin tsarin MEC don rage sawun carbon, haɗa hanyoyin makamashi mai sabuntawa a wuraren bakin ciki.

8. Ra'ayin Mai Bincike: Fahimtar Tsakiya, Tsarin Ma'ana, Ƙarfi & Kurakurai, Fahimta Mai Aiki
Fahimtar Tsakiya: Takardar ta gano daidai MEC ba a matsayin haɓaka kawai ba, amma a matsayin jujjuyawar tsari na asali—tura hankali da sarrafawa zuwa iyaka. Duk da haka, ta rage yin la'akari da sauyin tattalin arziki da aiki da wannan ke buƙata. Wannan ba matsala ta fasaha kawai ba ce; juyin juya halin tsarin kasuwanci ne. Dole ne kamfanonin wayar tarho su canza daga bututun bit zuwa masu samar da dandamali masu rarrabawa, canji mai zurfi kamar yadda AWS ya ƙirƙira lissafin girgije. Babban cikas ba fasahar da aka zayyana (NFV/SDN) ba ne, amma rukunin ƙungiyoyi da dabarun samun kuɗi na gado da dole ne ta rushe.
Tsarin Ma'ana: Tsarin takardar yana da inganci a ilimi amma yana bin tsarin "matsala-magani-kalubale" mai hasashe. Ya rasa damar tsara labarin cikin ƙarfi: MEC a matsayin hanyar tilastawa don dokokin jinkiri na kimiyyar lissafi a cikin duniyar dijital ta ainihin lokaci mai ƙaruwa. Ya kamata ta zama: Ƙuntatawa ta Jiki (jinkiri, bandwidth) -> Larura ta Tsari (rarraba lissafi) -> Ƙirƙirar Ƙimar Sabuwa (gogewa mai nutsewa, tsarin cin gashin kansu) -> Matsalar Aiki ta Sakamako (kalubalen huɗu). Tsarin da aka gabatar yana bayyana ne; yana buƙatar zama mafi yawan umarni da sakamako.
Ƙarfi & Kurakurai: Ƙarfi: Takardar tana ba da cikakken bayani game da manyan hanyoyin bincike na fasaha. Gano buƙatar "hanyoyin tsaro guda ɗaya" musamman yana da hankali, yana motsawa fiye da tsarin tsaro na akwatin zuwa ra'ayi na tsarin. Haɓaka ingancin makamashi tare da aiki yana da mahimmanci don tura ainihin duniya. Kurakurai Masu Bayyanawa: Binciken ba shi da jini. Yana ɗaukar kalubale kamar "gudanar da albarkatu" a matsayin wasanin gwada ilimi da za a warware, yana yin watsi da gaskiyar mawuyacin hali na mahalarta da yawa, yanayin mai siyar da kaya a bakin ciki. Wa ke mallakar uwar garken a bene na masana'anta? Kamfanin wayar tarho, masana'anta, ko babban mai girma? Yaya ake yin jayayya game da albarkatu tsakanin aikace-aikacen AR mai mahimmanci da rafin Netflix na ma'aikaci? Ƙirar takardar tana ɗauka mai ingantawa na tsakiya, ba gaskiyar tattalin arzikin bakin ciki mai rikitarwa, tarayya, kuma sau da yawa adawa ba.
