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 ...

Architecture / Philosophy: how, why, and what the questions seek in three case-studies from the late 20th century

André Patrão Neves De Frias Martins

Architecture and philosophy are no strangers to one another. In philosophical writings, architecture appears referred to, spoken of, described, defined, categorized, and figuratively used. In architectural discourse, by theoreticians and practitioners alik ...

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 ...
