Using Enterprise Models to Explain and Discuss Autopoiesis and Homeostasis in Socio-technical Systems

The article links two seemingly different fundamental theoretical concepts of autopoiesis and homeostasis and tries to apply them to the realm of socio-technical systems with the use of the Fractal Enterprise Model (FEM). Autopoiesis is the property of a s ...

A Novel Approach to Modeling Enterprise Services Leveraging Object Cloning and Multilevel Classification

Alain Wegmann, Lam Son Lê

Object-oriented modeling is concerned with capturing common properties of objects. The dominant thinking in this realm is to classify objects that share certain properties into what is called a class, which in turn enables us to instantiate additional obje ...

Specification and Implementation of a Meta-model for Information Systems Cartography

Alain Wegmann, Gorica Tapandjieva Sekulovska

Models are used in software engineering, enterprise architecture, requirements engineering, etc. In this context, models can give support in creating a shared understanding of what exists in an enterprise. For this purpose we suggest to use a cartography t ...

The Role of Invariants in the Co-evolution of Business and Technical Service Specification of an Enterprise

Alain Wegmann

We explore invariants as a linking mechanism between the business and technical service perspectives: From the business perspec- tive, invariants can be used to model (business) requirements of an en- terprise; from the technical perspective, invariants ex ...

Towards the Definition, Implementation and Communication of an IT Strategy: The Case of IT Strategy at EPFL

Alain Wegmann, Irina Rychkova, Gorica Tapandjieva Sekulovska, Didier Rey Marchetti

Large enterprises need to coordinate the IT initiatives that exist in different organisational units of the enterprise. If these initiatives are not coordinated, the resulting IT system is likely to become difficult to use and expensive to develop/maintain ...

Hierarchy-oriented modeling of enterprise architecture using reference-model of open distributed processing

Alain Wegmann, Lam Son Lê

Modeling Enterprise Architecture (EA) requires the representation of multiple views for an enterprise. This could be done by a team of stakeholders that essentially have different backgrounds. One way to do this is to structure the model into hierarchical ...

Geometric skeleton computation enabling concurrent product engineering and assembly sequence planning

Dimitrios Kyritsis

This paper introduces a novel modelling approach to geometric skeleton computation enabling concurrent product engineering and assembly sequence planning. Current engineering vision has recently moved towards new modelling and management paradigms to maint ...

SeamCAD: a hierarchy-oriented modeling language and a computer-aided tool for entreprise architecture

Lam Son Lê

Modeling Enterprise Architecture requires representing multiple diagrams of an enterprise, which typically shows the multiples business entities, IT systems, even software components and the services they offer. This could be done by a team of stakeholders ...

Formal semantics for refinement verification of entreprise models

Irina Rychkova

In this dissertation we investigate how Business/IT alignment in enterprise models can be enhanced by using a software engineering stepwise refinement paradigm. To have an IT system that supports an enterprise and meets the enterprise business needs, manag ...

An Example of a Hierarchical System Model Using SEAM and its Formalization in Alloy

Gil Regev, Alain Wegmann, Lam Son Lê, Irina Rychkova, José Diego de la Cruz Garcia

SEAM is an enterprise architecture method based on RM-ODP part 2. In this paper, we present an example of a SEAM hierarchical model where the behavioral part is formalized in Alloy. We introduce four kinds of actions and their relationships to properties t ...

Formal Semantics for Property-Property Relations in SEAM Visual Language: Towards Simulation and Analysis of Visual Specifications

Alain Wegmann, Irina Rychkova

SEAM is an enterprise architecture method that defines a visual language for modeling. Our goal is to provide formal semantics for SEAM. Model simulation, model comparison, and refinement verification are practical benefits we expect from this formalizatio ...

Defining business process flexibility with the help of invariants

Gil Regev, Alain Wegmann

Enterprise survival is about maintaining an identity that is separate from other enterprises. We define flexibility as the ability to change without losing identity. The identity of an enterprise can be analyzed as a set of norms and beliefs about these no ...

A Method of Functional Alignment Verification in Hierarchical Enterprise Models

Alain Wegmann, Irina Rychkova

Enterprise modeling involves multiple domains of expertise: requirements engineering, business process modeling, IT development etc. Our experience has shown that hierarchical enterprise models, made of an assembly of system models, are effective. In these ...

Modelling and monitoring industrial automation systems : with IEC 61346 and SFC

Rodrigo Garcia Garcia

The modelling of a manufacturing enterprise is not an easy task. A manufacturing enterprise is a complex system where technical knowledge is as important as management abilities. For taking more accurate management decisions and for these decisions to have ...

Implementation of a Modeling Tool Using Alloy as Meta-Modeling Language and CrocoPat as Validation Tool

Alain Wegmann, Lam Son Lê, Dirk Thilo Beyer, Lotfi Hussami

The context of our work is a project that focuses on methods and tools for modeling enterprise architectures. An enterprise architecture model represents the structure of an enterprise across multiple levels, from the markets in which it operates down to t ...

Business and IT Alignment with SEAM

Gil Regev, Alain Wegmann

Aligning business with IT requires understanding goals, strategies and needs. To be able to express them, an enterprise model can be developed. We present some of the traditional techniques used for the development of an enterprise model (value system, BPM ...

Definition of an Object-Oriented Modeling Language for Enterprise Architecture

Alain Wegmann, Lam Son Lê

In enterprise architecture, the goal is to integrate business resources and IT resources in order to improve an enterprises competitiveness. In an enterprise architecture project, the development team usually constructs a model that represents the enterpri ...
