With social pogess ad sciece ad techology apidly developmet, competitive spots evets competitios have also gow fiece, geat powes i iteatioal put cosideable emphasis o swimmig developmet, ad Chia also has o exceptio. Ameica is acowledged as powe i competitive swimmig evets i the wold, swimmig is also big evet that Ameica wis the gold medal i Olympic Games, which ca well explai swimmig evets decisive effects o iteatioal lage-scale competitios. I view of histoy, Chiese swimmig evets have both gloious ad lows i developmet pocess [-3]. I 99 Baceloa Olympic Games, its pefomace is pomiet that has achieved fou gold medals ad five silve medals i swimmig evets; i 000 Sydey Olympic Games, it has gaied othig i swimmig evets; i 008 Beig Olympic Games, it has achieved oe gold medal, thee silve medals ad two boze medals i swimmig evets [4-6]. With Chiese opeig-up ad efom as well as ecoomic system deepe efom, plaed ecoomy caused some afteeffects always affect ad estict Chiese swimmig competitive evets eseve talet cultivatio ad supplyig. Howeve, coespod to swimmig type eseve talet amout, quality high o low diectly affects Chiese swimmig type evets sustaiable developmet ad magificet taget implemetatio. Fo a log tem, Chiese swimmig type evet eseve talet maily elies o amateu spots school swimmig school spots school spots team the thee gades mode to cay out, the mode obviously caot adapt to iceasigly chaged wold ad bette povide high quality swimmig type eseve talet amout, the mode has suffeed some impact. heefoe, it affects Chiese competitive swimmig eseve talet impovemet ad populaizatio to some extet [7-0]. Chiese competitive swimmig evets have got some achievemets i ecet yeas, but with yealy Chiese 40

Swimmig type spots evets eseve talet cultivatio is a poblem that to be ugetly solved i competitive spots developmet, accodig to Chiese peset status, it should focus o swimmig eseve talet coespodig echelo costuctio, oly the ca Chiese competitive spots developmet get vey fa ad catch up with iteatioal advaced levels. MODEL ESABLISHMEN Fuzzy clusteig is a method that accodig to data afte stadadizatio, ad maes classificatio accodig to data elatios ad quatity sizes, it is geeally applicable to coelated factos to mae combiatio ad futhe gathe ito oe id. Fuzzy clusteig aalysis method Basic thought of fuzzy elatios equivalet fuzzy clusteig aalysis method is: due to fuzzy equivalet elatio is domai of discouse set U ad itself diect poduct U U oe fuzzy subset, mae pope decompositio o, hee use λ to expess hoizotal cut set o, the cutu U oe geeal subset λ is U oe equivalet elatio, ad so it also get oe id of classificatio of U classified objects elemets. Whe λ falls fom to 0, obtaied classificatio chages fom fieess to coaseess, ad gadually mege so that fom ito a dyamic clusteig tee diagam. heeupo, classificatio object set U fuzzy equivalet elatio establishmet is oe ey li i the clusteig aalysis method []. Establish fuzzy equivalet elatio: I ode to establish object classificatio set U * elatio, geeally we eed to fistly calculate each classified object similaity statistics, establish classificatio object set U fuzzy similaity elatio that is defied as. Fuzzy similaity elatio establishmet egadig each classificatio object similaity statistics computig, except fo adoptig icluded agle cosie fomula ad similaity coefficiet fomula, it ca also adopt followig computatioal fomulas. i j j,, L, m xi x / M i j Dot poduct method: M I above fomula, M is a pope selected positive umbe, i geeal, it should meet: i j j,, L, m c xi x i j Absolute value diffeece method: I above fomula, c 0 ( i j is a pope selected positive umbe, let.

Clusteig aalysis pocess based o imum fuzzy spaig tee, its steps is as followig. Step oe: Fist costuct a mutually fuzzy diagam. he opeate the step as followig method: Fist calculate classificatio items similaity statistics as classificatio object set U coespodig similaity elatio Expess as a m pieces of odes composed fuzzy diagam to have each side to coect, ad edow the side weight as.

CONCLUSION Swimmig team scale is expadig yealy, which eeds to stegthe maagemet so that ca well impove swimmig team eseve talet quality. Duig aalysis of swimmig team coaches, it is clea that coaches oveall quality is highe, age distibutio is elative easoable, duig coachig pocess, mostly follow syllabus cotets. Fom above types, we ca see that Chiese competitive swimmig evet eseve talet maagemet is elative easoable, which ca meet supplyig of Chiese swimmig team eseve talet. Ad meawhile it also hopes that Chiese swimmig team ca meet the expectatio, get good esults, ad seve the mothelad i iteatioal lage-scale competitios. EFEENCES [] ZHANG Mig-fei, CHEN Ya, ZHANG Yi-hua.
