What is Enterprise Integration?

Definition: the task of improving the performance of large complex processes by managing the interactions among the participantsCPC: what is this? between development and manufacturi

ng Supply Chain : between supplier and manufacture EI is normally pursed within the context of an emerging,

network-centric environment. Aims at streamlining process, breaking barriers, sharing knowledge,

Modeling Methodology

Overviewexisting enterprise engineering methodologies:

do not completely address collaboration and interaction. are less well suited to modelling certain dynamic aspects of

partners interactions

Integrated Methodology for Enterprise Engineering (IMEE), developed to meet key aspects of modelling multi-partner enterprises, incorporates two complementary kinds of modelling concept:

process oriented modelling in support of enterprise requirements capture and analysis, centered on ‘function’, ‘activity’ and ‘dynamic systems’ modelling and simulation approaches

object-oriented modelling in support of the conceptual design of multiple business systems, centered on ‘function’, ‘information’ and behaviour modelling.

IMEE

Overview - Three axes of enterprise modeling (why 4 bullets below?) Activity : unit of functionality to perform the business process

- Physical activity (PA): deals with the tangible - Logical activity (LA): deals with the intangible

Resource: something required to business process- mfg. facility, human resource, computing resource

Organization: personnel that perform business process Information : data, fact, or knowledge required to perform the business process

Requirements of EI Framework

Functional CapabilityRequirements

Business functions? (active components?) must co-operate with each other despite being distributed and owned by other enterprises

Functions on EI process must communicate with each other to attain the global goal

Functions and organizations which participate in the business process must be defined when designing business scenario

Interaction between functions following a given scenario must be defined with collaboration rules.

Resources of the business partners must be shared and controlled with business scenario

A Function must respond to other function’s task or result


Functional Capability Definition

Possibility of Cooperating through different functions and organizations from each different company

Ability to carry out certain types of activities, tasks or operations on a business process (why not “ability to produce a certain output”?)

Elements of function capability Information needed for function executionResource available for function executionResponse time required for functional response Execution time for required time spanOrganizations that deal with a task ???Priority compared with a current task ???

Synchronous interaction

Function B

A

Asynchronous interaction

• Function B must execute its task with given scenario, as soon as function B receive information that we called active• Thus, Function capability of function B must be considered when function B receives active information.

• Function B execute its task with given scenario, when function B need to do it• Function capability of function B is not considered. We called this information passive

Function Capability


Information Hub Requirements

Business information can be shared between business partners Data must be accessed through distributed environments

Data defined in EI environment are distributed logically or geographically and user may require information that is located in other database system

Data Schema and Semantic must be represented with common meaning?? Product Information must be shared between participants for efficient coll

aboration among set-maker?, suppliers, and customers in order to controls product quality and cost

Because Product information has many different views according to the business partner or business process such as SCM or Engineering process

The semantic of product information must coincide with business partner


Information HubDefinition

Common gateway to support data retrieve from and store into local databases through global database.

Global conceptual schema and local schema are definedData allocation is defined

Information Infrastructure Service Requirements

Despite heterogeneity, information access must be possible (not sure I captured your thought here).

Interoperability between computing components must be guaranteed Common business objects, such as suggested by BOMSIG of OMG will

support interoperability ???

Each system must be defined with common representation semantics ??? and syntax

XML will satisfy this requirement

EI environment is possible when the seamless integration of distributed components is guaranteed in spite of heterogeneities between computing resources of the participants


Information Infrastructure ServiceDefinition

Infrastructure Service that supports borderless access and control of distributed systems

IIS will be supported by the following to provide inter-operability:Business object based on CORBA, DCOM

with business object, Application systems do not need to revised or changed with system expanding, changing, or new construction

Flexible deployment or distribution of application is possible without consideration of each other application
