Deterministic womuenzaniso: tsananguro. The Mhando chikuru chokufunga deterministic yokutevedzera

Modelling chimwe chezvombo zvikuru muupenyu ano kana vachida kufanoziva remangwana. Uye ichi hazvishamisi, nokuti kururama nzira iyi chaizvo. Ngationei kuti deterministic muenzaniso munyaya ino.

Vhuṱanzi

Deterministic hurongwa mhando vane chinhu kuti kunogona kudzidzwa analytically, kana vari nyore. In nevakomana nyaya, kana uchishandisa vazhinji equations uye variables kuti chinangwa ichi chinogona vakavhiyiwa zvemagetsi makombiyuta. Uyezve, kushandisa kombiyuta, ave mutemo, zviri pamusoro kupfuura achitaura navo uye kuwana mhinduro. Nemhaka iyi, unofanira kuchinja mamiriro equations uye shandisa zvakasiyana zvakabudiswa. Izvi vlochet kune mikana yakawanda kukanganisa munyika Masvomhu. mhando dzose deterministic mienzaniso inozivikanwa ndechokuti zivo parameters pane imwe penguva akadzidza tikwanise kuziva zvakazara simba rinomutsa vana kukura mhiri kwemakungwa nenhamba vakakurumbira.

Features

Deterministic kwemasvomhu mhando usaregawo mawa kutsunga kufurirwa zvinhu zvakawanda, uye musatora nhoroondo zvakafanana dzavo dzinovaka mugadziriro. On chii akavaka functionality kwavo? Zvinonzi inobva kwemasvomhu mitemo anorondedzera mumuviri namakemikari dzinotsanagura chinhu. Nokuda ichi nokururamisira zvakarurama kufanotaura maitiro mugadziriro wacho.

Nokuti kuvakwa anoshandiswawo generalized equations nokupisa zvinhu zviyero, rinorondedzerwa macrokinetics muitiro. Nokuti kufungidzira yakarurama deterministic muenzaniso vanofanira kufadza zvichibvira nhamba kutanga mashoko pamusoro kare chinhu. Inogona kushandawo panyaya zvekushandisa matambudziko, izvo akabvumira kuti chero chikonzero kuregeredza chero nokufamba chaiyo iri tsika pakati parameters uye migumisiro nezviyero dzavo. Uyewo mumwe zvairatidza kuti kushandiswa ndechokuti neapo zvikanganiso zvingasanyanya kushanda hwokupedzisira kukarukureta wegadziriro.

Types Deterministic Modèles

Varege kuva / nguva nenguva. Both mhando kungava kuramba munguva. ivo achimiririrwa kutevedzana kwezviitiko discrete pulses. Vanogona kutsanangurwa kushandisa mufananidzo Laplace uye Fourier chinokosha nokuvonga.

Deterministic chinhu zvokushambadzira vane imwe ukama pakati mazano uye goho parameters acho. Vari inopiwa musoro womuenzaniso, differential uye algebraic equations (kunyange inogona kushandiswa uye avo mapedzero akauya ari kushanda nguva). Uyewo, sezvo hwaro pamusoro Masvomhu anogona kuti experimental mashoko dzakanga vakawana dzinongoitika ezvinhu kana mune nokukurumidza ngura nemiedzo. Chero muenzaniso deterministic inopa zvimwe paavhareji zvechadenga hurongwa.

Kushandisa upfumi

Ngatimboonai kushanda. Kuti aite izvi, chakakodzera deterministic muenzaniso pakushandisa Inventory. Zvinofanira kucherechedzwa kuti vari formalized mune boka Linear zvirongwa matambudziko.

Saka, nokuti Masvomhu zvakakodzera kuziva zvinotevera parameters: mari zviwanikwa uye goho kushandisa dzakasiyana-siyana modes okuwana, imwe neimwe ine yayo zvikuru; variables achirondedzera unhu zvose yokuvamba pezvakaitwa (kusanganisira yakatsvuka zvinhu). Zvose ane zviitwe. Mumwe nomumwe zvekuvaka, chigadzirwa, basa - zvose izvi kuna zvinhu mwero.

Uyewo kuti kukwana mhinduro zvakakodzera kupa nechinangwa tinyatsonzwisisa unhu zvisarudzo. Saka deterministic zvoupfumi mhando vari akakodzera kurondedzera pezvakaitwa izvo kuvimba kwokutanga mamiriro wegadziriro. Kana kushanda zvemagetsi makombiyuta zvinokosha kuyeuka kuti makombiyuta vanogona chete kushanda pamwe pazvinhu zvinokonzera.

Building mienzaniso

Pakazosvika nzira mharidzo inokosha parameters kuti zvichiitika pezvakaitwa zvinogona rakakamurwa mhando mbiri:

1. Rakada womuenzaniso. In kwavo nomumwe inogadzirwa zviumbu dzinoturwa se kutaridza wakaiswa vectors ose muganhu nzira kuti inoshanda kwavo.
2. Models pamwe shanduka parameters. Muchiitiko chino, uine vamwe kushanduka siyana, uye unoenderana Vector muganhu nzira dzokuwedzera equations nezvevanakomana.

Izvi deterministic chikonzero mienzaniso achibvumira kushandiswa kwavo munhu kuona migumisiro chaiyo urongwa mamwe maitiro. Asi kuenda makakombama kuzvitsaura akaverenga mashoko hakushandi. Kana ticharamba ngaaverenge simba Optimization dzamarudzi kugadzira, hazvifaniri kufunga probabilistic hunhu mashoko mberi sei muitiro.

factorial Modelling

References izvi zvinogona kuonekwa nyaya yose, asi chii, hatina asi kukurukurwa. Factorial Modelling zvinoreva kuti rine pfungwa zvokudya, izvo zvinoda munhu quantitative kuenzanisa. Kuti aite kudzidza ikabereka kutendeuka zvinangwa chimiro.

Kana nokuramba wakaomerera panzira deterministic womuenzaniso une zvinopfuura zviviri, kunonzi multi-chikonzero. Ongororo Yaro zvinogona anoitwa nzira dzakasiyana-siyana. Somuenzaniso, mashoko akarongeka nhamba. Muchiitiko chino, izvozvo anoona mabasa maererano pre-makasimbiswa uye akashanda ari priori yokutevedzera. Kusarudza pakati pavo rinoitwa musi mufananidzo zvakunoreva.

For yepamusoro kuvaka muenzaniso muchida kushandisa yokungotaura uye experimental kuongorora zviri musimboti kwacho uye ayo Matambudziko. Kuti ichi ndicho chikuru mukana nyaya pasi kukurukurwa. Model deterministic chinhu kuongorora kubvumira kufungidzira yakarurama munzvimbo zhinji hwedu. Nemhaka ravo yepamusoro uye ichiita mabasa akawanda, uye vakanga zvakapararira kudaro.

Cybernetic deterministic womuenzaniso

Ivo vari kufarira nokuda kuchinja kwacho kunobva kurutivi nenyaya kwatiri, izvo muka zvachose, kunyange kuchinja zvikuru vasingakoshi kuna kungatikanganisa hunhu kwezvakatipoteredza. Zvive nyore uye nokukurumidza kubva Masvomhu Nezvagara Zviripo kuchatsiviwa muenzaniso Chakarerutswa. Chinhu chinokosha ndechokuti anosangana zvose zvinodiwa zvinokosha.

Kubva kubatana vose anodiwa parameters zvaanoda nokushanda otomatiki kudzora maitiro uye kubudirira kwayo sarudzo. Zvakakosha kugadzirisa dambudziko iri: zvikuru mashoko achaunganidzirwa, dzakanga mukana kwokukanganisa uye zvikuru kugadzira nguva. Asi kana imi kutirambidza muunganidzwa mashoko ako, unogona kuverenga pamusoro zvishoma zvakavimbika zvabuda. naizvozvo zvakafanira kuti kuwana mwero achapa mashoko yakakwana zvakarurama, uye panguva imwecheteyo hakuzovipo buda kuoma pamwe zvisingakoshi okunze.

Multiplicative deterministic womuenzaniso

It inovakwa kupatsanura zvinhu zvavo yakatarwa. Somuenzaniso, funga muitiro rokuumba bhuku kugadzirwa (PP). Saka, unofanira kuva basa (RS), zvinhu (M) uye simba (E). Panyaya iyi, iyo chinhu pamusoro PP inogona kupatsanurwa kuva muzvizhinji (MS; M; E). musimboti ichi anoratidza multiplicative chinhu mhando maitiro uye mukana wayo kuparadzana. Muchiitiko ichi zvichibvira kushandisa nzira dzakadai shanduko: chiwedzerwa yakarongwa kuwedzera uye elongation. Kusarudza yokutanga zvikuru kushandiswa kuongorora. Inogona kushandiswa ngaaverenge kunyatsoshanda ari mushandi, uye zvichingodaro.

Pakukumbira rimwe ukoshi kuchatsiviwa zvimwewo. Asi pakupedzisira vanofanira zvakafanana nhamba. elongation muenzaniso kwataita pamusoro. It inongori yakarongwa kuwedzera. Kunosanganisira kushandisa kuwedzera yepakutanga dhinomineta chinhu muenzaniso nokutsiva rimwe kana kupfuura parameters. Funga muenzaniso uyu: isu kutarisira profitability okuwana. Nokuti mari iyi purofiti yakakamurwa kukura mutengo. Kana kuchangamuka pachinzvimbo chete ukoshi inokamukana nokuda akapfupikisa zvekushandisa kuti zvinhu, vashandi, mitero uye nezvimwewo.

Pasinei

Oh, kana zvose akaenda yakanyatsofanana aronga! Asi ichi zvinoitika kazhinji. Saka, muna tsika, aiwanzoshandisa pamwe deterministic uye probabilistic yokutevedzera. Tingatii pamusoro kare? peculiarity wavo kuti vanobvumira kuti zvakawanda uye zvakasiyana fungidziro. Somuenzaniso, sezvinotevera. Pane vaviri inoti. The ukama pakati pavo akaipa chaizvo. Wechitatu bato achasarudza kana kuti mari iri boka rimwe nyika. Pashure pezvose, kana hondo ikamuka, mubereko akuvadzwa kwazvo. Kana munhu anogona kumbotipa somuenzaniso rokuvaka muti munzvimbo dzakakwirira zvizivikanwe nemichina basa. Pano, nekuti pane dzinongoitika zvinhu haagoni zvawanikwa chokwadi, tinogona kuita izvi chete pamusoro.

mhedziso

Takurukura kuti vanomiririra deterministic womuenzaniso kuongorora. Haiwa, asi kunzwisisa navo zvizere uye kukwanisa kushandisa tsika, yakanaka chaizvo kudzidza. Yokungotaura Nheyo kare vane. Uyewo sezvo chikamu nyaya akaratidzwa uye mimwe mienzaniso iri nyore. Next yakanaka kuenda munzira zvishoma nezvishoma kuomesa yokushanda zvinhu. Unogona kuponesa vamwe achitaipa uye kutanga kudzidza Software kuti anogona kuita runoenzanirana simulation. Asi chero chisarudzo angava, kunzwisisa zvinokosha uye kuti kukwanisa kupindura mibvunzo ipi, sei uye nei, zvichiri zvakakodzera. Vanofanira kudzidza kutanga kusarudza zvakarurama kwezvavakaisa wasarudza achida kuita. Ipapo chirongwa achagona tobudirira kuita mabasa aro.
