## 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

## Stachowiak on Preterition and Abundance in Modelling

In his 1973 book “Allgemeine Modelltheorie” Herbert Stachowiak discusses the concepts of Preterition, Abundance and Contrastation of Original-Model mappings. This can be interpreted using homomorphism preservation and other logical concepts. Continue reading

## Stachowiak’s K-System of Modelling

Beyond the colloquial fundamental model properties Stachowiak gives a more formal definition of model: “Explication of the Concept of Model” … Continue reading

## General Model Theory by Stachowiak

In his 1973 book “Allgemeine Modelltheorie” (General Model Theory) Herbert Stachowiak describes the fundamental properties that make a Model: Mapping, Reduction, and Pragmatism. Continue reading

## Lecture Notes on Model Thinking IV

## 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: …
