    2. Lectures at the University of Bratislava/Autumn 2011 19.09.2011 Lecture 1 Introduction in CNO’s & Basics of Supply Networks 26.09.2011 Lecture 2 Kanban & Essential Supply Chain Processes 10.10.2011 Lecture 3 Business Processes & Semantic Web 17.10.2011 Lecture 4 SOA and SOA basing on J2EE 14.11.2011 Lecture 5 B2B & Cloud Computing Dr.Withalm

    3. Today’s Agenda • Brief introduction of ARIS • Connection SOA with ARIS • Event Control – Event Driven Process Chain (EPC) • Function Allocation Diagram • Information Flow Diagram • Event Diagram • Function Organization Data • EPC/PCD • Semantic WEB • Example • Ontology • Connection to WS Dr.Withalm

    4. ARIS(ARchitecture of integrated Information Systems)/1 • Main focus is modeling of business processes and their implementation on information systems • This architecture concept enables methods to be evaluated and organized • By concentrating on their focal points • And it also serves as an orientation Framework for complex development projects • Because in its structuring elements • It contains an implicit procedural model • For the development of integrated information systems Dr.Withalm

    5. ARIS(ARchitecture of integrated Information Systems)/2 • An architecure of this kind naturally leads toward standardization in the use of methods • As a result existing and new modeling methods were merged • To create a holistic method for modeling business processes • On the basis of this architecture • This ARIS architecture was then used as the basis for the development of the • ARIS toolset – a family of tools developed by IDS Scheer • i.e. ARIS Simulation, ARIS Web Publisher, ARIS Lotus Notes Connectivity • ARIS toolset supports consultants and companies in • Creating, analyzing, and evaluating company processes • For purposes of Business Process Reengineering Dr.Withalm

    6. ARIS(ARchitecture of integrated Information Systems)/3 • Following issues are tackled (more than 2000 pages!!): • Structure and structuring elements • Allocation of the individual modeling methods to the the structuring elements of the ARIS architecture. • Implementation of UML in ARIS • Implementation of OMT in ARIS • Knowledge Management methods • ARIS solutions for specific business management problems • ARIS BSC (Balanced Score Card) method • eBusiness Scenario Diagram and CBusinessMaps Dr.Withalm

    7. ARIS(ARchitecture of integrated Information Systems)/4 Dr.Withalm

    8. ARIS(ARchitecture of integrated Information Systems)/5 Dr.Withalm

    9. ARIS Analytical Views of the Process Model Dr.Withalm

    10. Process Model Views Dr.Withalm

    11. Example of a Process Chain Diagram Dr.Withalm

    12. Descriptive Levels of an Information System Dr.Withalm

    13. ARIS Concept Dr.Withalm

    14. Example of a Process Chain Diagram Dr.Withalm

    15. Representation of a Function • A function is a technical task or activity performed on an object in support of one or more company objectives • Elementary functions are functions which cannot be reduced any further for the purpose of business process analysis. • Example: Dr.Withalm

    16. Function Tree (Extract) Dr.Withalm

    17. Object –oriented Function Tree Dr.Withalm

    18. Process – oriented Function Tree Dr.Withalm

    19. Execution - Oriented Function Tree Dr.Withalm

    20. Mapping of an ARIS function onto a SOA service/1(Architecture of Integrated Information systems) Dr.Withalm

    21. Mapping of an ARIS function onto a SOA service/2 • The ARIS function which denotes a business service • Is directly mapped onto a SOA service • I/O data are mapped to the respective I/O data of the service • The operating entity is the SOA service provider • Activating and resulting events are elements of the service of the service consumer • In which the service is employed Dr.Withalm

    22. Event Control-Event-Driven Process Chain (EPC) /1 • Events such as Customer order received or Invoice produced define the point • at which a change in the state of information objects (data) occurs. • They are described in the data view of the ARIS architecture. • The procedural sequence of functions in the sense of business processes • is represented in process chains. • This means that the start and end events can be specified for each function. • Events are not only trigger functions, but they are results of functions. Dr.Withalm

    23. Event Control-Event-Driven Process Chain (EPC)/2 • By an event we understand the fact • that an information object (data) has taken on a business-relevant state • which is controlling or influencing the further procedure of the business process. • Unlike a function, which is a time-consuming occurrence, • an event is related to one point in time. Dr.Withalm

    24. Event Control-Event-Driven Process Chain (EPC)/3 • The change in state of an information object • may refer to the first occurrence of this information object • e.g., Customer order received • or to a change in state in the sense of a change in status • that is recorded in an attribute occurrence • e.g., Offer is refused. Dr.Withalm

    25. Event Control-Event-Driven Process Chain (EPC) /4 • Since information objects and attributes are described in the ARIS data view, • the event-driven representation of process chains is a link • between the data view and the function view. • Hence it is assigned to the ARIS control view. • Events are graphically represented as hexagons. • The description should not only contain the information object itself (Order), • but also its status change (received). Dr.Withalm

    26. Event Control-Event-Driven Process Chain (EPC)/5 Events (Graphical Representation): Dr.Withalm

    27. Event Control-Event-Driven Process Chain (EPC) /6 • Events trigger functions and are the results of functions. • By arranging this event-to-function change in a sequence, • so-called event-driven process chains (EPCs) are created. • An event-driven process chain (EPC) shows • The chronological-logical procedure of a business process. Dr.Withalm

    28. Event Control-Event-Driven Process Chain (EPC)/7 Example of EPC: Dr.Withalm

    29. Event Control-Event-Driven Process Chain (EPC)/8 • An example of an EPC is shown in above figure. • Since events determine which state or condition will trigger a function • and which state will define the end of a function, • the starting and end nodes of such an EPC are always events. • Several functions can originate simultaneously from one event and conversely • a function can have several events as its result. Dr.Withalm

    30. Event Control-Event-Driven Process Chain (EPC) /9 • A link in the form of a circle is used to represent • branches and processing loops in an EPC. • These connections, however, not only serve as graphic operators, • but define the logical links • between the objects they connect. Dr.Withalm

    31. Event Control-Event-Driven Process Chain (EPC) /10 Dr.Withalm

    32. Event Control-Event-Driven Process Chain (EPC)/11 • In the first example of above Figure • the starting events are linked by an AND operator. • This means that the procedure Release operation • is only started if a routing is available • and the necessary resources have been verified. • Therefore, both events must have occurred before the procedure can begin. Dr.Withalm

    33. Event Control-Event-Driven Process Chain (EPC) /12 • The second example shows an exclusive OR operator • The Check supplier offer function may either result • in acceptance or rejection of the quote. • Both results, however, cannot occur at the same time. Dr.Withalm

    34. Event Control-Event-Driven Process Chain (EPC) /13 • Besides these two cases and the "Inclusive OR" operator, • more complex relationships are conceivable. • In this case, a general rule can be represented in an EPC • which will be described later in more detail in the form of a rule diagram. Dr.Withalm

    35. Event Control-Event-Driven Process Chain (EPC) /14 • Therefore, we can distinguish between two different types of operators: • Event operators • Function operators Dr.Withalm

    36. Event Control-Event-Driven Process Chain (EPC)/15 overview of all possible event operators: Dr.Withalm

    37. Event Control-Event-Driven Process Chain (EPC)/16 overview of all possible function operators: Dr.Withalm

    38. Event Control-Event-Driven Process Chain (EPC) /17 • In this context, special attention must be paid to the restrictions • which exist for function operators. • Due to the fact that events cannot make decisions • Only functions can do this • a triggering event must not be linked using an OR or XOR operator ! • Below, possible operators are explained using examples. Dr.Withalm

    39. Event Control-Event-Driven Process Chain (EPC) /18 Operator for Triggering Events /1AND Operator The function can be started only after all events have occurred. Dr.Withalm

    40. Event Control-Event-Driven Process Chain (EPC) /19 Operator for Triggering Events /2OR Operator • The function will be carried out • after at least one of the events has occurred. Dr.Withalm

    41. Event Control-Event-Driven Process Chain (EPC) /20 Operator for Triggering Events /3XOR operator • The function is started after exactly one and only one event has occurred. Dr.Withalm

    42. Event Control-Event-Driven Process Chain (EPC) /21 Operator for Created Events /1AND Operator • The function results in all events occurring. Dr.Withalm

    43. Event Control-Event-Driven Process Chain (EPC) /22 Operator for Created Events /2OR Operator • Executing the function results in at least one of the events occurring. Dr.Withalm

    44. Event Control-Event-Driven Process Chain (EPC) /23 Operator for Created Events /3XOR Operator • Executing the function results in one event at the most occurring. Dr.Withalm

    45. Event Control-Event-Driven Process Chain (EPC) /24Linking of functions with created events /1AND Operator of Functions with Created Events • The event occurs only after all functions have been carried out. Dr.Withalm

    46. Event Control-Event-Driven Process Chain (EPC) /25Linking of functions with created events /2OR Operator of Functions with Created Events • The event occurs after at least one of the functions has been carried out. Dr.Withalm

    47. Event Control-Event-Driven Process Chain (EPC) /26Linking of functions with created events /3XOR Operator of Functions with Created Events • The event occurs when exactly one of the functions • has been carried out. Dr.Withalm

    48. Event Control-Event-Driven Process Chain (EPC) /27Linking of functions with triggering events /1AND Operator of Functions with Triggering Events • The event triggers all functions. Dr.Withalm

    49. Event Control-Event-Driven Process Chain (EPC) /28Linking of functions with triggering events /2OR Operator of Functions with Triggering Events • Events have no decision-making power! • This operator is not possible! Dr.Withalm

    50. Event Control-Event-Driven Process Chain (EPC) /29Linking of functions with triggering events /3XOR Operator of Functions with Triggering Events • Events have no decision-making power! • This operator is not possible! Dr.Withalm
