Q

Overview of lectures this week

Interactive models for enterprise modeling – More on

EEML for modeling interactive models

Dynamic networked organizations / Virtual Enterprises Presentation of an overall infrastructure for supporting

networked organizations

Experiences and results Based on

• A2: Interactive models for Supporting Networked

Organizations (some overlap with A1)

• A3: Interactive Models for Virtual Enterprises
• A4: Moran, T., Cozzi, A. and Farrell, S.P. Unified activity

management

Q

Interactive models

Visual (graphical) models of enterprise aspects (goals,

tasks, roles, organizations, persons, information, systems...)

Available for industrial users to be viewed, traversed,

analyzed, simulated, adapted, and executed

Changes to the models influence the information

systems supporting the enterprise/business network

Examples

• Emergent Workflow
• Dynamic ontologies
• Product models
• Information retrieval

Activation

Activation = Initiative + Interpretation + Action 3 ways

Manually through users Automatic through a system Interactivly: User and system cooperate

Automating Informating Reactive users Proactive users

Q

EEML - Background

EEML - Extended Enterprise Modelling Language Originally developed in EXTERNAL to support

development and use of interactive models

Also for other types of enterprise modeling (sense-

making, context for systems development)

Enterprise modelling on type and instance level Used as input for UEML (UEML, INTEROP) and POP*

(ATHENA)

Further developed in Norwegian research project

(MONESA)

The approach also taken further in EU (MAPPER

project) and as basis for spin-off company (AKM)

Current version EEML2005

Conceptual metamodel of main parts: Goal modelling and process modelling

TDT4250 - Modeling of Information Systems, Autumn 2006

Q

Process modelling

Task (instance and type level) Decision point (milestone, start, end, input, output) Resource roles (object, organization, person, tool)

• Object usage (CRUD)
• Person role type (participant, customer, responsible)

Flow (control/data/material flow)

Q

Goal modelling

Goal

• If context then deontic operator achieve state
• Deontic operator: Necessitate, obligate, recommend, permit,

discourage, forbid, contradict

Goal connectors for more advance goal-hierarchies Goal-relationships

• goal deontic operator goal (argument)

Goal applies to task/milestone/resourcerole/resource Goal is action rule for task Goal is precondition/decision rule/postcondition for

decission point

Role/resource source of goal

Q

EEML vs. modeling perspectives

Structural: UML class diagrams, information

• bjects

Functional: Task modelling Behavioral: Flow of control in process models Rule-oriented: Goal hierarchies Object-oriented : Class diagrams, but process

focus

Social communication: E.g. ’Conversation for

Action’ can be expressed through specific patterns of decision-points and tasks

Actor/role-oriented: well covered
