Title: BIZNESA PROCESU MODELE


1
BIZNESA PROCESU MODELEŠANA IZMANTOJOT
METAMODELEŠANAS PANEMIENUS
  • Valdis Vitolinš
  • Promocijas eksamens

2
Saturs
  • Modeli, metamodeli un metamodelešana
  • Unified Modeling Language (UML) 2.0 standarti
  • (pasaule, kura dzivojam)
  • Petijumu apraksts
  • Vienots biznesa procesa metamodelis
  • Biznesa procesu merišana
  • UML 2.0 aktivitašu diagrammas preciza semantika
  • Biznesa procesu transformacijas
  • Turpmakie petijumi

Kas ir metamodelešana
  • Metamodelešana ir modelešanas valodas un tas
    likumu izstrade.
  • Metamodelešana ir visparigu likumu piemerošana
    (instancešana) konkretiem modeliem vairakos
    piegajienos, ta veidojot vairakus metaslanus.
  • Metamodelešana ir modelu izstrade, pielietošana
    un manipulacijas ar tiem, taja skaita ari modelu
    transformacijas
  • Metamodelis ir preciza modela un ta semantikas
    (jegas) apraksts, kas nepieciešams modela
    izveidei.

Kas ir biznesa procesu modelešana
  • Biznesa procesu modelešana (Business Process
    Modeling - BPM) ir ir uznemuma darbibas
    aprakstišana ieskaitot pašreizejo un velamo
    stavokli, un iespejams ari izmainu (parejas)
    procesu no esoša stavokla uz velamo stavokli.
  • BPM tiek veikta, izmantojot dažadas BPM valodas,
    rikus un metodikas.
  • Mes galvenokart izmantojam
  • UML valodu (Unified Modeling Language),
  • MDA (Model Driven Architecture) konkretak - MDD
    (Model Driven Development) metodiku.

    parasti neaplukojam, jo attiecas uz
    implementaciju)

Musu apvienotais uznemuma (biznesa) metamodelis
  • Apvienotaja metamodeli ir daudzi jedzieni, kas
    škiet svarigi biznesa analitikiem, bet kuru nav
    UMLa. Acimredzot tapec, ka UML vesturiski ir
    veidojies ka programmaturas izstrades, nevis
    biznesa analizes standarts.
  • Zimigi vardi ir Notataion Independent tas
    atspogulo musu ta laika domas par kopigo
    metamodeli dažadam valodam

14
Musu biznesa procesa metamodelis
Metamodelis sasaucas ar UML 2.0 aktivitašu
diagrammu, bet tas ir papildinats ar jaunam
klasem un asociacijam (stipri modificets).
Piem. Performer klase un Actor asociacija ir
janievedums, kas ir nacis no musu biznesa procesa
profila (pakotnes). Šadi papildinajumi gan ir
saskana ar MOF un UML, bet datu apmainu starp
dažadiem rikiem veikt nevar, jo papildinajumus
tie var nesaprast.
15
GRADE BM un UML 2.0 Aktivitašu diagrammu piemeri
  • Abas valodas aprakstits tas pats biznesa process

16
Biznesa modelu transformacija kopeja metamodela
pieeja
  • Dažadas valodas uzskatijam ka valodas
    neatkarigu jedzienu attelojumus

17
Modelu transformacija pirms MOLA
  • Exigen Business Modeler pieeja izmantojot
    kopigo metamodeli

Pareizak butu teikt, ka šeit veikta modelu
salagošana (mapping), jo transformacija tira
veida netiek veikta. Šobrid, izmantojot MOLA,
modeli tiktu parveidoti no viena uz otru,
izlaižot Notation Independent Domain.

Kas ir biznesa procesu merišana
  • Biznesa procesa meri ir jedzieni, kas attelo
    dažadus biznesa procesu aspektus (ipašibas)
  • Laiks
  • Nauda
  • Resursi
  • Kvalitate
  • ar precizu definiciju un jegu
  • Ar precizu skaitli un mervienibu.
  • Saskana ar Gartner, biznesa procesu preciza
    merišana ir noteikta ka kritiska Biznesa procesu
    parvaldibas (BPM) joma.
  • Gartner, Inc, Executive Report Library, Winning
    Asset Management Series. Introduction and Report

  • Farok J. Contractor, Valuation of Intangible
    Assets in Global Operations, Quorum Books, 2001
  • Bet neviena no šim metodikam nav balstita uz
    metamodelešanu, tapec var teikt, ka nav
    pietiekami preciza un formala

21
Balanced Scorecard metodika
  • Dažadas meru perspektivas
  • (Customer, Financial, Internal, Learning
    Growth)
  • Katras perspektivas meri izsakami ar preciziem
    skaitliem

22
Intangible Asset Monitoring
  • Bazeta uz Balanced Scorecard metodiku
  • Piedava dažadus skaitliski izmeramus merus
    netaustamiem raditajiem, un daleji ari to
    saistibu, piem.
  • Indicators of Growth
  • Indicators of Renewal/Innovation
  • Indicators of Efficiency/Utilisation
  • Indicators of Risk/Stability
  • Indicators of Renewal/Innovation
  • Iesaka pielietot skaitliskus merus ari dažadam
    gaisigam lietam, ka piem. customer satisfaction
    ka atgriezušos klientu skaitu, vai procentu no
    visiem apkalpotiem klientiem, u.tml.

23
Nopietnakie riki ar procesu merišanu
  • GRADE, IDS Scheer ARIS, Popkin Software System
    Architect
  • Lauj merit procesu simulaciju (laiks, izmantotas
    instances, rindas, u.tml)
  • Merus uzdot atseviška simulatora
  • Sekojošie riki praktiski atbalsta tikai Internal
    Business un Financial perspektivu merus, kurus
    var piemerot procesu parvaldibai
  • Meru agregacija notiek veidojot parskatus, pašam
    jazin, ko un ka saskaitit
  • QPR ScoreCard
  • Elementarajam aktivitatem predefineti vienadi
    meri, ka
  • Izpildes laiki (sakums, beigas, kopejais ilgums,
    aktivais ilgums)
  • Izmaksas, objektu dekompozicija var sadalit
    izmaksas
  • Skaititaji ( defektiem, kopejais skaits u.tml.)
  • Lidz ar to, ne visiem elementa meriem ir butiska
    jega (reala varbut ir)
  • CaseWise Corporate Modeler

Biznesa procesa modelis no iekšpuses (klašu
diagramma)
  • Šaja atteloti visi Make Order procesa elementi
    (ieklaujot aktivitašu diagramma neredzamos), ka
    konkretas metamodela instances.
  • Attelojumam ir nestandarta pieeja
  • metamodela klase ir attelota ka stereotips,
  • t.i. ltltBusiness Processgtgt Make Order , jalasa ka
    Make OrderBusiness Process
  • metamodela dekompozicija attelota ka modela
    dekompozicija ar konkretam klasem, un konkretam
    asociacijam
  • (UML standarta ieteikta klases nodalijuma
    (compartment) izmantošana iespejama tikai vienai
    metamodela-gtmodela parejai)

26
Meru definicijas metamodelis (M2 slanis)
  • Ari šis metamodelis ir veidots ar specigo
    pielagošanu, ieviešot jaunu Biznesa procesu
    merišanas profilu.
  • Meru definicijas metamodelis ir izmantojams ka
    šablons biznesu procesa meriem (uz metamodeli
    balstita) rika.
  • T.i. rika jau ir defineti gatavi procesa biznesa
    meri un to vertibu aprekinašanas veids
    (formula).

27
Meru veidi un to saistiba ar biznesa procesu
definicijas elementiem (M2 slanis)
  • ltltContainergtgt meriem var uzdot gatavus veidus, ka
    tiek agregeti sastavdalu meru rezultati (jasumme,
    javidejo, jaskaita ka procenti u.tml.)
  • Šis modelis vairak lasams ka konceptuala
    diagramma, kas atspogulo musu domas par
    noderigiem biznesa procesu meriem, neka precizs
    metamodelis. Lai metamodelis butu precizs, taja
    butu jaatspogulo metaklašu instancu un
    metaasociaciju instancu konkretas vertibas, bet
    ka jau tika noradits, UMLa nav noderigu veidu, ka
    to isti attelot.

28
Biznesa procesu meru metametamodelis (M3 slanis)
  • Šaja darba mes ne tikai izveidojam savu
    metamodeli (biznesa procesu merišanas profilu),
    bet patiesiba izveidojam ari savu metametamodeli
    jeb MOFu.
  • Ka labumu var minet to, ka šadi specializejot
    UML MOFu, mes varam vienkaršot metamodeli, jo
    daudzas vajadzigas ipašibas (piem., sapratigi
    ierobežojumi) mums jau ir iešutas MOFa
  • Tas gan ir saskana ar MOF standartu, kas pielauj
    dažadus MOFus
  • Tomer, tas lauž tradicijas, jo apgrutina datu
    apmainu (ko gan varetu labot ar transformacijam)

Jateic, ka šobrid mes cenšamies dzivot preciza
saskana ar UML MOFu un UMLu, lai varam mierigu
sirdsapzinu apgalvot, ka mes dzivojam saskana ar
tiem.

Musu izveidota AD VM ir savadaka no UML standarta
  • Implemente tikai apakškopu (kas nepieciešama
    biznesa procesu parakstišanai)
  • Elementi no Fundamental, Basic, Intermediate,
    daži no Complete Activities
  • Activities, Actions, Control and Object Flows,
    Activity Parameter Nodes, Pins, Control Nodes,
    Activity Partitions and Groups
  • Ierobežojumi diagrammam
  • outgoing edge from a ControlNode is not an
    incoming edge for the same ControlNode
  • there should be no paths between
    CallBehaviorActions, InitialNodes, FinalNodes or
    ActivityParameterNodes containing both ForkNodes
    and JoinNodes

Forbidden Constructs
38
Activity Diagram standarta semantika
  • Control Nodes with Guards are working as "traffic
    switches for visibility of offered tokens
  • Only active elements are Action Engines
  • They try to fill up their input pins with sets of
    tokens using "transitive closure visibility of
    offered tokens
  • Activity Diagram Standard Semantics
  • visibility rules are harder to implement than
    simple actions
  • Processing of offered tokens all at once
    doesnt work correctly for Single Execution mode
    (important for simulation) - concurrent control
    tokens may be lost

39
Musu virtualas mašinas semantika
  • Edges and Control nodes between stable nodes are
    concatenated into Paths
  • PassRule is created from Guards of Paths edges
    which are "anded" together
  • each PassRule can be evaluated independently
  • Main active elements are Push and Pull token
    Engines
  • provide token movement between stable nodes
    (actions, initial, final)
  • Push engines are used for outgoing branches
  • Pull engines are used for incoming branches
  • Our semantics
  • Simple and more suitable for execution
  • Works also in Single Execution mode

40
AD metamodela apakškopa un atbilstošas ADVM klases
41
Celi (Paths) un markieru dzineji (Token Engines)
  • Paths are created as a "transitive closure" of
    Edges and IntermediateNodes between Queues of
    StableNodes.
  • constraints and conditions, coming from Guards
    and Control Nodes are "concatenated" into the
    PassRule
  • TokenEngines for queues are added the following
    way
  • if for an OutputQueue there exists at least one
    OutgoingPath without Join, then a PushEngine for
    this OutputQueue is created
  • if for an InputQueue there exists at least one
    IncomingPath with Join, then a PullEngine for
    this InputQueue is created

(bez ActivityFactory klases)
43
Musu ADVM ekvivalence un izmantošana
  • Equivalence
  • Essential event trace starts of action
    executions and the token sets consumed and
    produced by these actions are the same for both
    virtual machines on any activity diagram.In our
    subset of UML Activity Diagrams
  • there is no real race for tokens by actions in
    the selected subset(no implicit fork, no forks
    in a path leading to a pull engine, mutually
    exclusive guards for decisions)
  • any token will be delivered to its destination in
    our VM not later than in the original VM
  • assertion that all input pins must have at least
    one token (or an appropriate group of tokens, if
    this is a join pin) for the action to start,
    becomes true at exactly the same moment when the
    original VM would have finally collected all the
    offered tokens
  • Usage
  • Works well for BPM and workflow systems, easily
    implementable
  • AD simulator a tool important for workflow
    validation

  • Petijumi uzsakti 2005. gada un tiek turpinati.
  • Petijuma rezultati ir apvienoti raksta Use of UML
    and Model Transformations for Workflow Process
    Definitions, kas tiek gatavots iesniegšanai
    konference.

Kas ir biznesa procesu transformacijas
  • Musdienu pasaule pastav daudz un dažadas
    modelešansa valodas, kuras var izmantot biznesa
    procesu modelešanai
  • UML 2.0 Activity Diagram
  • UML 2.0 State Machine
  • JPDL - jBPM Process Definition Language.
  • DSL -Domain Specific Language (biznesa procesu
    modelešanas profils gan nav definets)
  • BPEL - Business Process Execution Language for
    Web Services
  • XPDL (XML Process Definition Language), BPML
    (Business Process Modelling Language), YAWL (Yet
    Another Workflow Language)
  • Ir ari daudz un dažadi dzineji, kas izpilda
    procesu definicijas (šobrid vairums no tiem
    izpilda uz UML stavoklu diagrammu bazetas
    valodas).
  • Musu uzskats ir ka izstradajot sistemas ar MDD
    pieeju nepartraukti rodas vajadziba transformet
    modelus
  • abstraktaku procesa definiciju konkretaka valoda
    (PIM-gtPSM transformacija),
  • Procesa definiciju viena valoda uz citu lidzigu
    valodu (PIM-gtPIM transformacija)
  • Ja transformacijas nav iespejams veikt
    automatiski, MDD ideja nav dzivotspejiga, jo tad
    biznesa procesu ir izdevigak uzreiz implementet
    kada specifiska veida (programmešanas valoda).

Derek Miers, Paul Harmon, The 2005 BPM Suites
Report,Process Modeling Simulation Tools Report
  • Analize (define) Workflow sistemas
  • Norada uz svarigajam funkcijam
  • Integracija (prasme izsaukt citas sistemas),
  • Automatizacija (kontroles strukturas, izveles,
    cilpas)
  • Resursu parvaldiba (t.i. materiali un ari
    cilveki)
  • Dažadi uzdevumu veidi (sistemas iekšiene, citu
    sistemu izsaukšana, manualas operacijas)
  • Atbalstu manualu operaciju veikšanai uzsveram ari
    mes

BPMN vs AD
  • Stephen A. White, Process Modeling Notations and
    Workflow Patterns
  • BPTrends March, 2004, http//www.omg.org/bp-corner
    /pmn.htm
  • Apgalvo, ka BPMN un UML AD ar laiku sapludis
    viena valoda, jo esot loti lidzigas. Mes tam
    nepiekritam, jo metamodeli ir loti dažadi
  • Dažadi skaidrots (biznesa un viena sadarbibas
    partnera) procesa jedziens,
  • AD ir vairak datu plusmas vadita, bet BPMN
    vairak notikumu vadita
  • Howard Smith, BPM and MDA Competitors,
    Alternatives or Complementary
  • Ari apgalvo lidzigi, ka UML AD un BPMN ir lidzigi
  • AD ir PIM pec definicijas, bet
  • Domas dalas, vai PSM jabut izpildamam, daži
    uzskata, ka PIM ir tuvaks biznesa limenim un
    tadas lietas ka iterators, vertibu pieškiršana
    PIMa nav vajadziga
  • Bet, tad, lai PIMu varetu izpildit, transformejot
    uz PSMu, bus jaliek klat (parasti jaimplemente
    manuali) kaut kas papildus
  • BPMN tiek uzskatita par PIM, bet dažas jomas ta
    ir specifiskaka par AD.Tai ir labak izstradata
  • procesu sadarbiba
  • procesu veiceju norade operacijam
  • dažadu veidu procesu (iekšejie, izsaukumi uz
    arejam sistemam, manuali) izdališana

Business Process Definition Metamodel
  • Standarts
  • Business Process Definition Metamodel Revised
    Submission to BEI RFP bei/2003-01-06, Object
    Management Group (OMG), http//www.omg.org/docs/be
    i/04-01-02.pdf
  • Sasaucas ar Stephen A. White, un ir dots
    vienkaršako diagrammas elementu mapings no BPMN
    uz AD,
  • Nav mapojuši pašu galveno - Business
    Process/Process/Pool/Lane uz AD un tas elementiem
  • Notikumu mapošana ir vienkaršota, nav nemti vera
    start/intermedia/end notikumu mapošanas atškiriba
    uz AD elementiem,
  • Nav nemta vera elementu asociaciju pretejo galu
    elementu mapošana

Jaunakas zinas BPMN un OMG
  • Endrju Votsona (Andrew Watson) 9-Nov-2005
    prezentacija "OMG s new modelling
    specifications
  • norada, beidzot ari OMG ir kerušies pie biznesa
    modelešanas sakartošanas. Vinš min jomas, kas
    augsta limeni sasaucas ar musu pedejo gadu
    petijumiem
  • Business motivation model (biznesa apkartne)
  • Business Process Modelling Notation (dinamikas
    apraksts BPMN AD vieta)
  • Semantics of Business Vocabulary Rules
    (statiskas strukturas apraksts)
  • Organisational structure metamodel (beidzot!)
  • Šobrid balstas uz musu veco ideju, ka BPMN un AD
    var pabazt zem vienota metamodela cepures.
  • Talak paradisim, ka ar transformaciju to izdarit
    ir efektivak, jo nav vajadzigas nedabigas
    kopigas konstrukcijas

PIM -gt PSM workflow transformacijas
  • Stephen A. White "Using BPMN to Model a BPEL
    ProcessBPMN -gt BPEL (Business Process Execution
    Language (for Web Services))
  • Jean Bezivin, u.c., Applying MDA Approach to B2B

  • Keith Mantell, From UML to BPEL, Model Driven
    Architecture in a Web services world AD -gt BPEL
  • Ta ka merka valoda (BPEL) ir šaura, izmanto tika
    dalu no workflow definešanas lidzekliem (tikai
    automatiskas proceduras), iztrukst
  • resursu parvaldiba
  • manualu operaciju atbalsts
  • Nav darbu, kas veiktu pilnvertigu (musu izpratne)
    workflow transformaciju

Biznesa process, aktivitašu diagramma un BMPNa
53
AD biznesa procesa profils (M2 slanis)
  • Šis ir Aktivitašu diagrammas metamodela dala,
    (MOLA transformacijas avots)
  • Metamodelis ir papildinats, izmantojot vajo
    paplašinašanu, t.i. izmantojot tikai stereotipus.
  • Ar stereotipiem metamodelis mainits netiek -
    stereotipiem var tikai pievienot papildus
    elementarus atributus, vai mainit esošo
    asociaciju jegu, bet nevar ieviest jaunas klases
    vai asociacijas

54
BPMN metamodelis (M2 slanis)
  • Šis ir BPMN metamodela dala, (MOLA
    transformacijas merkis)
  • Metamodelis ir veidots pec Business Process
    Modeling Notation (BPMN), Version 1.0 - May 3,
