Saadka difaaca iyo diyaarnimada Qaabka tooska ah

Shabakad ilaalin guud heerka caqiidada dadweynaha iyo buugaagta waxbarashada: 24 madal oo guud, 8 koox dayactir, kaydsan sahayd oo gawaaridu quudiyaan, shabakad raadiyo oo 12 kanaal leh iyo shan goob oo dareemayaal ah. Ma jirto nidaam, cutub ama hawlgal dhab ah oo la jilayo — kani waa cilmi-baaris hawlgal oo ka dambeysa diyaarnimada.

Xakamayaal

Saacadaha hawlgalka madal kasta maalintii. Xawaare badan, jabka iyo shidaalka badan.

Ka mid ah 8 koox dayactir; inta kale waxay ka shaqeeyaan madalada.

Qayb ka qaado madal hore u sugaysa qaybo. Way ka dhakhso badan tahay, laakiin shaqada waa laba jibaarayaa.

Saacadaha u dhexeeya socodka gawaarida sahayda (culays go'an socod kasta).

Masaafadu waxay kortaa xididka afraad ee awoodda; isticmaalka shidaalku wuxuu kordhaa si toosan.

Wicitaannada caadiga ahi ma qaadan karaan r kanaal oo bannaan ee ugu dambeeya.

Waxay ballansataa hal shixnad mudnaan leh: ilaa 4 dalab oo furan ayaa yimaada 24 saacadood gudahood. Hal shixnad oo keliya ayaa hawada ku jiri karta hal mar, mid kastana waxay ka dhacdaa miisaaniyadda gaadiidka.

Waxay ku dartaa 4 kanaal kadib 3 saac oo dejin ah; waxay isticmaashaa shidaal yar.

Xaaladaha dhibaatada

Heerka 1 · Kor-u-kaca diyaarnimada

Layli ayaa afar maalmood labanlaab ka badan ka dhigaya baahida saacadaha hawlgalka. Qaybaha dayactirku waa yar yihiin, sahayda caadiga ahi waxay qaadataa afar maalmood, miisaaniyadda gaadiiduna waxay daboolaysaa laba shixnadood oo mudnaan leh. Keen saacadaha adigoon burburin diyaarnimada, adigoon kaydin dalabaad dib u dhacay, adigoon xannibin shabakadda raadiyaha.

  • Ugu yaraan 790 saacadood oo hawlgal ah oo kooxda qalabka inta kor-u-kacu socdo
  • Celceliska diyaarnimada hawlgalka ≥ 86 % laga bilaabo saacadda 30
  • Celceliska dalabaadka dib u dhacay ≤ 2 maalinta ugu dambeysa
  • Ugu badnaan 2 shixnadood oo mudnaan leh (miisaaniyadda gaadiidka)
  • Celceliska xannibaadda mudnaanta ≤ 2 %
  • Celceliska xannibaadda caadiga ah ≤ 35 %

Heerka 2 · Waddada sahaydu waa xiran tahay

Daad ayaa xidha waddada keliya ee kaydsanka 60 saac. Gawaaridu way safsafaan gadaashiisa. Ka dhig kaydku inuu sii jiro adigoon u oggolaan dabooleynta ilaaladu inay burburto.

  • Kaydku marnaba ma madhan (xad adag)
  • Celceliska dabooleynta ilaalada ≥ 89 %
  • Ugu yaraan 60 saacadood oo hawlgal ah oo hawlgallo ah ka hor inta aan waddada la xidhin
  • Wadar ahaan ugu yaraan 440 saacadood oo hawlgal ah oo kooxda qalabka
  • Ugu yaraan 255 saacadood oo hawlgal ah kadib marka waddada dib loo furo

Heerka 3 · Carqalad raadiyo iyo cillado dareemayaal

Carqalad ayaa burburisay badhkii kanaallada raadiyaha. Laba iyo toban saac kadib laba goob oo dareemayaal ah way guuldareystaan. Ka dhig taraafikada mudnaantu inay socoto oo soo celi dabooleynta.

  • Celceliska xannibaadda mudnaanta ≤ 3 %
  • Celceliska dabooleynta ≥ 88 % kadib cilladda dareemayaasha
  • Celceliska xannibaadda caadiga ah ≤ 40 % (ha ka saarin taraafikada caadiga ah gabi ahaanba)
  • Celceliska diyaarnimada hawlgalka ≥ 80 %

Aasaas — moodelka ka dambeeya tirooyinka

Xiriir kasta oo jilaha isticmaalo, iyo ilaha uu ka yimid. Mudnaanta lagu calaamadiyay malo-awaal waa hagaajin muunad ah.

Diyaarnimada hawlgalka: qaybta waqtiga nidaamku diyaar yahay, oo ay ku jirto dib-u-dhaca saadka.
Ao = uptime / (uptime + downtime) ≈ MTBF / (MTBF + MTTR + MLDT)[1][2]
Madaladu si aan kala sooc lahayn ayay u guuldareystaan iyagoo leh waqti-ilaa-guuldarro tibaax ah marka ay hawlgalayaan.
P(fail during h operating hours) = 1 − e^(−h/MTBF), MTBF = 40 h[2]Malo-awaal: MTBF, suurtagalnimada qaybta, heerarka isticmaalka iyo taraafikadu waa tirooyin qorshayn guud ah, ma aha xog nidaam dhab ah.
Aragtida Palm: iyadoo beddelka mid-mid ah, qaybaha tubada ku jira waxay raacaan qaybinta Poisson.
pipeline ~ Poisson(mean = demand rate × lead time); backorders = (pipeline − S)⁺[4][3]
Dayactirradu waxay sugaan safka ay u adeegaan tiro go'an oo koox ah.
c teams serve the maintenance queue (M/M/c); site teams + fleet teams = 8[9]Malo-awaal: MTBF, suurtagalnimada qaybta, heerarka isticmaalka iyo taraafikadu waa tirooyin qorshayn guud ah, ma aha xog nidaam dhab ah.
Maalmaha sahayda: inta ay kaydkeedu sii jiri doonto isticmaalka maanta.
DOS = stock / daily consumption[10]Maalmaha sahaydu waa cabbir qorshayn oo laga isticmaalo caqiidada ilaalinta; saamigu laftiisu waa xisaab fudud.
Xannibaadda Erlang B, iyo balaadhintiisa saxda ah marka kanaallo loo kaydiyo taraafikada mudnaanta leh.
B(0)=1, B(k) = A·B(k−1) / (k + A·B(k−1)); with reservation r: exact birth–death chain[5][6]
Isleegga radar-ka: masaafada ogaanshuhu waxay kortaa xididka afraad ee awoodda la diray.
R ∝ P^(1/4) ⇒ πR² ∝ √P[7]
Mudnaanta kale ee qorshaynta ee uu moodelku isticmaalo.
MTBF 40 operating h · part needed 40 % · repair Exp(6 h) · sites MTBF 300 h, repair Exp(8 h) · convoy 200 u · burn 1 u per operating h + 0.5 u/h per site at full power · relay +4 channels after 3 h · priority shipment: ≤ 4 open orders, lands within 24 h, one in flight at a time · ≥2 channels always open to routine trafficMalo-awaal: MTBF, suurtagalnimada qaybta, heerarka isticmaalka iyo taraafikadu waa tirooyin qorshayn guud ah, ma aha xog nidaam dhab ah.
Moodelka dabooleynta Boolean: suurtagalnimada in barta ay aragto ugu yaraan mid ka mid ah dhowr saxan oo dareemayaal ah.
coverage = 1 − exp(−Σ πR_i² / A)[8]Malo-awaal: MTBF, suurtagalnimada qaybta, heerarka isticmaalka iyo taraafikadu waa tirooyin qorshayn guud ah, ma aha xog nidaam dhab ah.

Aan-kala-sooc: abuurahaha mulberry32 oo abuur leh; qaybinta la isticmaalay — isku-mid, tibaax (CDF rogan), caadi (Box–Muller), Poisson (Knuth). Abuurka waa la muujiyaa waana la wadaagi karaa.
