Imodeli Deterministic: definition. Izinhlobo ezinkulu isici onobuhle deterministic

Modeling ingenye amathuluzi ebaluleke kakhulu empilweni yesimanje lapho befuna ukubona ikusasa kusengaphambili. Futhi lokhu akumangalisi, ngoba ukunemba kwale ndlela kuphezulu kakhulu. Ake sibheke ukuthi imodeli deterministic kulesi sihloko.

ulwazi olujwayelekile

Deterministic izinhlelo onobuhle nesici okungatholakala wafunda analytically, uma ilula ngokwanele. Endabeni okuphambene, uma usebenzisa inani elikhulu zibalo kanye eziguquguqukayo le njongo ingase eziqhutshwa amakhompyutha electronic. Ngaphezu kwalokho, usebenzisa ikhompyutha, njengoba umthetho, kuba ezingaphezu kuka ukhuluma nabo futhi ukuthola izimpendulo. Ngenxa yalokhu, kufanele ushintshe uhlelo of zibalo bese usebenzisa izibonelo zalokho ezahlukene. Lokhu vlochet ukuba babe sengozini enkulu yokufa iphutha izibalo. Zonke izinhlobo onobuhle deterministic libhekene iqiniso lokuthi ulwazi nemingcele at isikhawu ezithile wafunda kusenza sikwazi ukunquma ngokugcwele Dynamics ukuthuthukiswa kwezilwandle izibalo ezidumile.

Izici

Deterministic onobuhle zezibalo ungavumeli ukuzimisela kanyekanye yethonya izici eziningi, futhi ungathathi akhawunti ye interchangeability yabo ohlelweni impendulo. Ukwakhela phezu kwasiphi eyakhelwe ukusebenza kwabo? Kusekelwe imithetho zezibalo ezichaza izinqubo zemvelo namakhemikhali into. Ngenxa yalesi sasivumela ukubikezela ngokunembile ukuziphatha wesistimu.

Ukuze ukwakhiwa nazo asetshenziswa zibalo generalized ukushisa nokubanda impahla ezilinganisweni, kuchazwa macrokinetics inqubo. Ukuze ukubikezela okunembile ngaphezulu imodeli deterministic kufanele abe inombolo enkulu ngangokunokwenzeka ulwazi kokuqala mayelana esidlule into. Kungasetjenziswa mayelana nezinkinga lobuchwepheshe, esangenza ngenxa yanoma yisiphi isizathu ukuba sidebeselele iyiphi iyehla iyenyuka yangempela abakuzuzile imingcele futhi imiphumela izilinganiso zabo. Futhi kungenye yezinkomba ukusetshenziswa wukuthi amaphutha wezikhathi kungase kungabi nethonya elitheni endleleni ukubala kokugcina kohlelo.

Izinhlobo onobuhle Deterministic

Ingase ingatholakali / gqwa. Zombili lezi zinhlobo zezindlu kungenzeka okuqhubekayo ngesikhathi. nabo umelwe ukulandelana pulses leyehlukene. Bona lingachazwa usebenzisa umfanekiso Laplace futhi Fourier sibonga ebalulekile.

Deterministic isici onobuhle sibe nobuhlobo ezithile phakathi input bese okukhipha kwemigomo inqubo. Ingabe okunikezwa okunengqondo imodeli, umehluko kanye algebraic zibalo (nakuba ingasetshenziswa nezisombululo zabo esichazwa ngokuthi umsebenzi isikhathi). Futhi, njengesisekelo izibalo angenza idatha ngokwakho, zazitholakala ezimweni zemvelo noma yashesha ukugqwala ukuhlolwa. Noma yimuphi imodeli deterministic ihlinzeka izici ezithile isilinganiso uhlelo.

Ukusebenzisa umnotho

Ake sibheke ngokoqobo. Ukuze wenze lokhu, ukulingana deterministic imodeli ukulawula yokusungula. Kufanele kuqashelwe ukuthi zenziwe zibe semthethweni eklasini zezinkinga izinhlelo lwento.

Ngakho, i-izibalo ezidingekayo ukucacisa amapharamitha alandelayo: izindleko izinsiza kanye okukhipha usebenzisa ezihlukahlukene izindlela zokukhiqiza, ngamunye ephethe umfutho ayo; eziguquguqukayo echaza izici kuzo zonke izinqubo ezenzeka (kuhlanganise izinto zokusetshenziswa). Konke kufanele lokho kuxazululwe. Ngamunye isisetshenziswa ngazinye, umkhiqizo, umsebenzi - konke lokhu kulethwa ibhalansi impahla.

Futhi ngenxa ukuphelela izixazululo kudingekile ukunikeza ukuhlolwa Inhloso izinga izinqumo. Ngakho, deterministic onobuhle kwezomnotho mahle ukuchaza izinqubo ezincike ku isimo sokuqala kohlelo. Lapho besebenza ngamakhompyutha electronic kuyadingeka ukuze bakhumbule ukuthi amakhompyutha kungasebenza kuphela nge izici isilungisiwe.

onobuhle Isakhiwo

Ngu indlela zokubukwa nemingcele eziyisisekelo okwenzeka izinqubo zingahlukaniswa zibe izinhlobo ezimbili:

1. imodeli isilinganiselo. Ngo ngabanye ukukhiqizwa amayunithi abo ethulwa njengoba iqoqo zithwala elimisiwe ongakhetha umngcele ekusebenzeni kwabo.
2. Amamodeli ngezimiso onhlobonhlobo. Kulokhu, isibonisa ezithile ukushintshashintsha ububanzi, futhi vector elihambisana izinketho umngcele zibalo ezengeziwe yethulwe.

Lezi isici onobuhle deterministic okuvumela ukusetshenziswa umuntu zabo ukunquma umphumela ukulungiselwa okuthile ukuze izici ezithile. Kodwa ukuya Curves ngokuhlukana ibalwa inkulumo ngeke zisebenze. Uma sizobe abale nokwenza ashukumisayo zokukhiqiza okuqhubekayo, akufanele acabangele ubunjalo probabilistic ulwazi sendlela yokuqhubeka izinqubo.

ukumodeliswa ngokwesimo

Izinkomba lalokhu lingabonakala kuso sonke lesi sihloko, kodwa kuyini, asizange okwamanje kuxoxwa. Ngokwesimo ukumodeliswa kusho esimayelana izihlinzeko, edinga ukuqhathanisa ambalwa. Ukuze wenze ucwaningo ekhiqizwa ngenhloso ukuguqulwa komumo.

Uma imodeli isandla deterministic has izici engaphezu kwemibili, ibizwa ngokuthi multi-factor. ukuhlaziywa kwalo engenziwa ngezindlela ezihlukene. Njengoba isibonelo, izibalo zezibalo. Kulokhu, icabangela imisebenzi ngokuya zangaphambi osungulwe futhi wasebenza onobuhle priori. Ukukhetha phakathi kwabo kwenziwa umfanekiso okunenjongo.

Ukuze ukwakhiwa eliphezulu imodeli ofuna ukuyisebenzisa uphenyo theory kanye nama-yokulinga okushiwo inqubo kanye causality yayo. Ukuthi lokhu inzuzo enkulu yalokho ababexoxa ukucabangela. Model deterministic isici ukuhlaziywa uvumele ukubikezela okunembile ezindaweni eziningi ezimpilweni zethu. Ngenxa yabo eliphezulu futhi enza izinto ezihlukahlukene futhi wawusakazeke ngakho.

Cybernetic imodeli deterministic

Ziyakwazi nesithakazelo ngenxa inqubo shintsho esekelwe ukuhlaziywa kithi, okuyinto kuphakama nhlobo, ngisho izinguquko awuwona yini ongelutho kunayo uhlobo ezonakalisayo imvelo. Ukuze kube lula futhi ijubane izibalo isimo indawo a imodeli lula. Into ebalulekile ukuthi lihlangabezana zonke izidingo eziyisisekelo.

Kusukela ubunye bonke nemingcele ezidingekayo ukusebenza engaphansi othomathikhi elawula uhlelo ukusebenza izinqumo zayo. Kuyadingeka ukuba ukuxazulula le nkinga: ulwazi oluthe xaxa izoqoqwa, ayanda namathuba okuba nenkinga futhi mkhulu processing time. Kodwa uma ubeke umkhawulo ukuqoqwa idatha yakho, ungakwazi ukubala imiphumela kangako. Ngakho-ke kudingekile ukuba uthole ukulinganisela ezonikeza ulwazi ukunemba okwanele, futhi ngesikhathi esifanayo ke ngeke ngokungadingekile kuyinkimbinkimbi oluxube ezingadingekile.

Okuguquliwe imodeli deterministic

It yakhiwa sokuhlukanisa izici ku isethi yabo. Njengoba isibonelo, cabanga inqubo obumba ivolumu ukukhiqizwa (PP). Ngakho, udinga ukuba ne-labour (RS), izinto (M) namandla (E). Kulokhu, lo Isici PP zingahlukaniswa zibe sebuningini (MS; M; E). Lokhu samuntu ibonisa okuguquliwe isici lwesistimu futhi kungenzeka ukuba bahlale ngokuhlukana yayo. Kulokhu kungenzeka ukusebenzisa izindlela ezinjalo ukuguqulwa: isandiso ukunwetshwa letihlelekile naletingakahleleki ukunwebeka. Inketho yokuqala kabanzi lisetshenziswe analysis. Ingasetshenziselwa ukubala nekusebenta umsebenzi, nokunye.

Lapho kuyoshaya inani elilodwa esikhundleni nezinye izinto. Kodwa ekugcineni kufanele abe namaswidi alingana. ukunwebeka Ngokwesibonelo sixoxe ngenhla. It uhlala kuphela ukwanda esisemthethweni. Luhilela ukusetshenziswa ukwandiswa yasekuqaleni zihilela isici imodeli ngokufaka esikhundleni esisodwa noma ngaphezulu nemingcele. Cabanga ngalesi sibonelo: silindele inzuzo ukukhiqizwa. Ngenxa yalesi inani inzuzo ehlukaniswa usayizi izindleko. Lapho izithombe esikhundleni inani elilodwa lihlukaniswe by ukusetshenziswa kwemali wafingqa izinto, izisebenzi, izintela nokunye.

amathuba

Oh, uma konke kwahamba kahle njengoba kuhlelwe! Kodwa lokhu kwenzeka akuvamile. Ngakho-ke, empeleni avame ukusetshenziswa ndawonye onobuhle deterministic futhi probabilistic. Singathini ngezinto zesikhathi esidlule? engavamile wabo ukuthi uvumele kwenzeke kakhudlwana futhi ehlukile. Ngokwesibonelo, cabangela izinkondlo, kanje. Kunezinhlobo ezimbili uthi. Ubudlelwano obuphakathi kwabo kubi kakhulu. Umuntu wesithathu ozonquma ukuthi izimali zami kule nkampani ka kwelinye lamazwe. Phela, uma impi Kugqashuka inzuzo kakhulu ubuhlungu. Noma umuntu angabona zilandise njengesibonelo ukwakhiwa zalesi sihlahla esifundeni umsebenzi okusezingeni eliphezulu zokuzamazama komhlaba. Lapha, ngoba kukhona izinto zemvelo ezingeke zaba isiqiniseko, singazenza kuphela lokhu obakhathalelayo.

isiphetho

Sixoxe labamele deterministic imodeli ukuhlaziywa. Maye, kodwa ukuqonda ngokuphelele kubo futhi bakwazi zisebenza ku umkhuba, lihle kakhulu ukufunda. Izikhwama theory kakade. Futhi njengengxenye izihloko banikezwe futhi ezinye izibonelo elula. Okulandelayo engcono ukuya endleleni inkinga kancane kancane impahla ukusebenza. Ungagcina ezinye ukuthayipha bese uqale isofthiwe ukufunda ukuthi angafeza sekulingisa okuhambisanayo. Kodwa kungakhathaliseki ukuthi ukukhetha kungenzeka, ukuqonda eziyisisekelo kanye ukuze sikwazi ukuphendula imibuzo ngalokho, kanjani futhi kungani, kusadingeka. Kumelwe ufunde ukuqala ukukhetha okokufaka okulungile bese ukhetha isenzo oyifunayo. Khona-ke lolu hlelo uzokwazi ngempumelelo ukufeza imisebenzi yayo.
