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

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: …
