Dipatimenti ya VTB IT kangapo idayenera kuthana ndi zochitika zadzidzidzi pakugwira ntchito kwa machitidwe, pomwe katundu wawo adakwera nthawi zambiri. Chifukwa chake, pakufunika kupanga ndikuyesa chitsanzo chomwe chinganeneretu kuchuluka kwazinthu zofunikira kwambiri. Kuti achite izi, akatswiri a IT aku banki amakhazikitsa zowunikira, kusanthula deta ndikuphunzira kupanga zolosera. Tidzakuuzani m'nkhani yaifupi zida zomwe zidathandizira kuneneratu za katunduyo komanso ngati zidathandizira kukhathamiritsa ntchitoyo.
Mavuto omwe ali ndi ntchito zolemetsa kwambiri amapezeka pafupifupi m'mafakitale onse, koma kwa gawo lazachuma ndizovuta kwambiri. Pa ola la X, magulu onse omenyera nkhondo ayenera kukhala okonzeka, choncho kunali koyenera kudziwiratu zomwe zingachitike komanso kudziwa tsiku limene katunduyo adzalumphira ndi machitidwe omwe angakumane nawo. Zolephera ziyenera kuchitidwa ndi kupewedwa, kotero kufunikira kokhazikitsa dongosolo lolosera lolosera sikunakambidwe nkomwe. Zinali zofunikira kukonzanso machitidwe malinga ndi deta yowunikira.
Analytics pa mawondo anu
Ntchito yolipira malipiro ndi imodzi mwazovuta kwambiri zikalephera. Ndizomveka bwino pakulosera, chifukwa chake tidaganiza zoyamba nazo. Chifukwa cha kulumikizana kwakukulu, ma subsystems ena, kuphatikiza ma remote banking services (RBS), amatha kukumana ndi zovuta nthawi zambiri. Mwachitsanzo, makasitomala amene anasangalala ndi SMS za chiphaso cha ndalama anayamba kugwiritsa ntchito mwakhama. Katunduyo ukhoza kulumpha moposa dongosolo la ukulu wake.
Chitsanzo choyamba cholosera chinapangidwa pamanja. Tinatenga zojambulidwa chaka chatha ndikuwerengera masiku omwe nsonga zapamwamba zimayembekezeredwa: mwachitsanzo, 1st, 15th ndi 25th, komanso masiku otsiriza a mwezi. Chitsanzochi chinkafuna ndalama zambiri zogwirira ntchito ndipo sichinapereke chidziwitso cholondola. Komabe, idazindikira zovuta zomwe zidali kofunikira kuwonjezera zida, ndikupangitsa kuti zitheke kukhathamiritsa njira yotumizira ndalama pogwirizana ndi makasitomala a nangula: kuti asapereke malipiro mugulp imodzi, zochitika zochokera kumadera osiyanasiyana zidasiyanitsidwa pakapita nthawi. Tsopano timawakonza m'magawo omwe mabanki a IT atha "kutafuna" popanda kulephera.
Titalandira zotsatira zabwino zoyambirira, tidapitilira kulosera zam'tsogolo.
Kugwirizana njira
VTB yakhazikitsa njira yowunikira kuchokera ku MicroFocus. Kuchokera kumeneko tinatenga kusonkhanitsa deta kuti tilosere, njira yosungiramo zinthu ndi ndondomeko yoperekera malipoti. M'malo mwake, kuyang'anira kunali kale, zomwe zidatsala ndikuwonjezera ma metric, gawo lolosera ndikupanga malipoti atsopano. Chisankhochi chimathandizidwa ndi makontrakitala akunja a Technoserv, kotero ntchito yayikulu pakukhazikitsa polojekitiyi idagwera akatswiri ake, koma tidapanga tokha chitsanzocho. Njira zolosera zidapangidwa kutengera Mneneri, chinthu chotseguka chopangidwa ndi Facebook. Ndiosavuta kugwiritsa ntchito ndipo imaphatikizana mosavuta ndi zida zathu zophatikizira zowunikira komanso Vertica. Mwachidule, makinawo amasanthula graph yonyamula ndikuyiwonjezera kutengera mndandanda wa Fourier. N'zothekanso kuwonjezera ma coefficients ena masana, otengedwa kuchokera ku chitsanzo chathu. Ma metric amatengedwa popanda kulowererapo kwa anthu, zoloserazo zimawerengedwanso kamodzi pa sabata, ndipo malipoti atsopano amatumizidwa kwa olandira.
Njirayi imazindikiritsa ma cyclicities akuluakulu, mwachitsanzo, pachaka, mwezi uliwonse, kotala ndi sabata. Malipiro amalipiro ndi zopititsa patsogolo, nthawi yatchuthi, tchuthi ndi malonda - zonsezi zimakhudza kuchuluka kwa mafoni ku machitidwe. Zinapezeka, mwachitsanzo, kuti mikombero ina imadutsana, ndipo katundu wamkulu (75%) pamakina amachokera ku Central Federal District. Mabungwe ovomerezeka ndi anthu amachita mosiyana. Ngati katundu wochokera ku "katswiri wa sayansi ya zakuthambo" akugawidwa mofanana pamasiku a sabata (izi ndizochepa zazing'ono), ndiye kuti makampani 99,9% amagwiritsidwa ntchito pa maola ogwira ntchito, ndipo zochitikazo zingakhale zazifupi, kapena zikhoza kukonzedwa mkati mwa angapo. mphindi kapena ngakhale maola.
Malingana ndi zomwe zapezeka, zochitika za nthawi yayitali zimatsimikiziridwa. Dongosolo latsopanoli lawulula kuti anthu akuyenda mochuluka kupita ku mabanki akutali. Aliyense akudziwa izi, koma sitinayembekezere kukula koteroko ndipo poyamba sitinkakhulupirira: chiwerengero cha mafoni ku maofesi a banki chikuchepa mofulumira kwambiri, ndipo chiwerengero cha zochitika zakutali chikukula mofanana ndendende. Chifukwa chake, katundu pamakina akukulanso ndipo apitiliza kukula. Tsopano tikulosera za kuchuluka kwake mpaka February 2020. Masiku wamba akhoza kuneneratu ndi cholakwika cha 3%, ndi masiku apamwamba ndi cholakwika cha 10%. Izi ndi zotsatira zabwino.
Zowopsa
Monga mwachizolowezi, izi sizinali zopanda mavuto. Makina owonjezera omwe amagwiritsa ntchito mndandanda wa Fourier samadutsa ziro bwino - tikudziwa kuti mabungwe azovomerezeka amapanga zochepa kumapeto kwa sabata, koma gawo lolosera limatulutsa zinthu zomwe sizili kutali ndi ziro. Zinali zotheka kuwawongolera mokakamiza, koma ndodo si njira yathu. Kuphatikiza apo, tidayenera kuthana ndi vuto lochotsa deta mopanda ululu kuchokera kumakina oyambira. Kutolera zidziwitso pafupipafupi kumafuna zida zamakompyuta, chifukwa chake tidapanga zosungira mwachangu pogwiritsa ntchito kubwereza ndikulandila zambiri zamabizinesi kuchokera ku zofananira. Kusapezeka kwa katundu wowonjezera pa machitidwe ambuye muzochitika zotere ndizofunikira zotsekereza.
Mavuto atsopano
Ntchito yowongoka yolosera nsonga zamtsogolo idathetsedwa: sipanakhale zolephereka zochulukirachulukira kubanki kuyambira Meyi chaka chino, ndipo dongosolo latsopano lolosera lidathandiza kwambiri pa izi. Inde, sizinali zokwanira, ndipo tsopano banki ikufuna kumvetsetsa momwe nsonga zake zilili zoopsa kwa izo. Tikufuna kulosera pogwiritsa ntchito ma metrics kuchokera pakuyesa katundu, ndipo pafupifupi 30% ya machitidwe ovuta awa akugwira ntchito kale, ena onse ali mkati molosera. Pa siteji yotsatira, tidzaneneratu za katundu pa machitidwe osati muzochita zamalonda, koma malinga ndi zomangamanga za IT, mwachitsanzo, tidzapita pansi pagawo limodzi. Kuphatikiza apo, tifunika kupanga makina osonkhanitsira ma metric ndikumanga zolosera motengera iwo, kuti tisamatsitse. Palibe chosangalatsa pa izi - tikungodutsa kuyang'anira ndikuyesa kuyesa molingana ndi machitidwe abwino apadziko lonse lapansi.
