## Categories of semantic Models by Stachowiak

Categorisation by example of semantic models, i.e. models as we use them in software engineering etc, according to Herbert Stachowiak. Continue reading

## Stachowiak on semantic Requirements Modelling

Excerpt of Herbert Stachowiak’s “Allgemeine Modelltheorie” (General Model Theory). Although this is on empirical-scientific models, it provides a foundation of semantic requirements modelling. Continue reading

## Modelling with Classes: Square and Rectangle revisited

Classic problem in class-modelling: how to express that a square is a special kind of rectangle? In order to deepen understanding, let us scrutinize the situation a bit closer here, using logical/ structural foundations of modelling: Continue reading

## Reflections on Abstractions: Subsumption I

We’re going to look at a subsumptional mapping from lhs original to rhs model. We will get four cases of subsumption as in figure (strictest cases), which now can be developed into a continuum with the four cases as corner points. Continue reading

## Modelling Theory and Abstraction Awareness in 2012

Little collection of Tweets on Modelling and Abstraction in 2012: Model Thinking, Application, Conceptual and Formal Foundations etc. Continue reading

## Human centric Modelling

There is a modelling at the low-end, that we use every day a million times, and there is modelling at the high-end with comprehensive concepts like UML, MDD etc. Both are good to have. Perhaps approaching the modelling topic from the low-end would make it easier accessible for most of the software practitioners. Continue reading

## Modelling Abstraction etc in 2011

Just reviewed my Twitter timeline of 2011: … (tweets, links, and wisdoms of the year) Continue reading

## Complexity Awareness is Cost Awareness

If “engineering is producing an artifact to cost”, then how can modelling contribute to it? Continue reading

## Rhinos – a Modelling Theorist’s Perspective

A structure of rigurous and relevant principles are necessary and sufficient to constitute a Modelling Theory. Everything else, like processual, behavioural, ontological or linguistic considerations, is optional. Let me enlighten this position, with the help of last week’s Rhino posting: …
