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

Gil Regev

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

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, 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

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 ...

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

Alain Wegmann, Gil Regev, 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

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

Alain Wegmann, Gil Regev

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 ...
