Simulation - ib tug tseem ceeb heev txoj kev

Model - ib tug tshiab khoom, uas qhia tag nrho cov ntsiab yam ntawm cov kev kawm uas yog tau kawm. Nyob rau hauv tag nrho cov spheres ntawm science lawv kawm los ntawm ntau cov ces kaum. Ib tug thiab tib yam khoom tej zaum yuav muaj ib tug ob peb ua qauv, thaum ib tug ntau ntawm lawv muaj peev xwm yuav thaws rov los nyob rau hauv ib tug. Nws yog tsim nyog rau peb nyob rau hauv thiaj li yuav muaj peev xwm qhia ib yam dab tsi los yog piav qhia txog. Piv txwv li, thaum tsim ib tug tshiab aircraft engine designers yuav tsum xyuas nws nyob rau hauv tus txheej txheem ntawm nyuaj davhlau tej yam kev mob. Tom qab tag nrho, ce yog nyob rau hauv kev muaj tiag - nws phomsij ib txoj kev kuaj tsav. Yog li ntawd, cov tau davhlau tej yam kev mob yuav tsum simulated rau tshwj xeeb sawv.

Nws hais ntxiv hais tias lub simulation - ib tug muaj kev ruaj ntseg thiab ntau yam ntawm tej yam kev mob. Tej qauv, ib txoj kev los sis lwm, yuav tsum ua raws li nrog tus kwv, thiab nws yuav ua tau zoo ib yam li nws nyob rau hauv:

• tsos;
• qauv;
• tus cwj pwm.

Simulation - qhov no yog qhov tseem ceeb txoj kev kawm, uas muaj txog cov creation thiab kev tshawb fawb chaw. Nws yog siv los muab tau tag nrho cov lus qhia nyob rau hauv tus txheej txheem nyob rau hauv txoj kev tshawb no, uas yog tsim nyog rau cov kev pom kev tshuaj kev pab raws qib. Tab sis nyob rau tib lub sij hawm, tsis muaj qauv tsis hloov ib tug tiag tiag kev tshwm sim. Tsuas yog nyob rau hauv kev daws tej kev pab raws qib, tej zaum nws yuav pab tau, thiab tej zaum lub cuab tam tsuas ntawm kev tshawb fawb.

Modeling - yog:

• cov kev hloov ntawm lub sij txheej txheem ntawm nws imitation;
• tsim tau ib tug qauv ntawm cov khoom los yog cov txheej xwm;
• Kawm nyob rau hauv lub tsim cov qauv.

Nws li nram no los ntawm lub foregoing hais tias cov modeling - nws yog ib feem ntawm tej kas ua si.

kev faib

Simulation system yog muab faib ua 3 chav kawm:

1. Nyiaj.

2. Abstract.

3. Cov Ntaub Ntawv.

Tus heev txheej txheem ntawm qauv yuav cov nram qab no cov kauj ruam:

1. Lub hom phiaj ntawm los.

2. Ib qho kev ntsuam ntawm tag nrho cov zog ntawm qhov system.

3. rho tawm ntawm lawv lub tseem ceeb tshaj plaws nta.

4. Xaiv qhov zoo.

5. Formalization.

6. Analysis ntawm cov qauv tso zis.

7. Mus saib cov adequacy ntawm tus qauv tau los ntawm lub system thiab lub hom phiaj ntawm txoj kev tshawb.

Modeling thiab formalization

Ntuj lus yog tsim los tsim kuas ntaub ntawv ua qauv. Tsim kuj cia koj mus ua lwm kuaj. Qhov no yog hu ua formalization.

Ib qho ntawm feem ntau tsim lus yog kev kawm txog zauv - nws tso cai rau formulate lub functionality ntawm qhov tseem ceeb. Nyob rau hauv no txoj kev, Newton pom tau hais cov formalization ntawm lub heliocentric system ntawm lub ntiaj teb no, thawj sab kev cai lij choj ntawm universal gravitation thiab cov cai ntawm mechanics thiab sau ntawv rau lawv nyob rau hauv daim ntawv ntawm cov zauv sib raug zoo.

Cov neeg tam sim no siv modeling thiab tsim los ntawm kev txawj ntse ntawm tej ib chig. Tab sis li cas yog nws hais tias kom "formalization"? Qhov no yuav txo tau ntawm ib tug cov ntsiab lus ntawm cov xaiv zoo lawm. Piv txwv li, ib tug txheej txheem - qhov no yog qhov formalization ntawm ib tug ntau heev ib feem ntawm nws, thiab cov ntawv nyeem rau nws tus kheej - ib daim ntawv qhia los ntawm cov lus ntawm kev xav, reflections thiab cov tswv yim ntawm cov neeg sau ntawv.

Lub peev xwm ntawm txoj kev no yog raws li nyob rau hauv qhov siv txoj hauj lwm, yog hu ua cov yooj yim thesis. Lub essence ntawm ib tug kwv los yog system tsis hloov yuav ua li cas peb hu lawv. Qhov no txhais tau tias lawv yuav tsum tau hu ua li hais tias lub npe ntau li ntau tau mus ntsib lawv. Tsis kam muab cov formalization ntawm lub ntsiab tswv yim sib cav yog hais tias lub npe ntawm lub chaw los yog yuav tsum qhia nws cov essence. Yog li ntawd, nyob rau hauv cov ntaub ntawv no, nws yuav tsum tau muab tsuas yog ib lub npe.
