Abstract
This paper is dedicated to Paul Stähly on the occassion of his 65 th birthday. It reflects many private discussions between us, in particular, on modelling and the use of an appropriate programming language. Paul Stähly has always been a dedicated user of SIMULA 67, already in those days when object oriented programming (OOP) was not invented yet. He has early noticed the power of object orientation in his research area (OR). The authors of SIMULA 67 introduced classes as templates which define data structures and algorithms to be included in a particular instance (of a model). In addition, classes may be defined in terms of each other. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
