Models and modelling methods play an essential role in Operational Research and Management Science (OR/MS). This article presents four models which concern how OR/MS employs different modelling methods for different modelling tasks, under different constraints, and for different forms of uncertainty. Two of these “meta-models” concern how OR/MS modelling has been employed in decision support for the Swedish Defence Research Agency: one of them from a more academic or theoretical perspective, the other more from the perspective of the practitioner. The third model concentrates on how different modelling techniques are constrained by varying stakeholder positions. The final model is introspective and classifies a variety of modelling methods on the basis of a number of formal modelling properties. All of these meta-models were developed using the non-quantified modelling method General Morphological Analysis (GMA).

On a Morphology of Theories of Emergence

Greetings,

For those who are interested in the principle of “emergence” and/or general morphological analysis (GMA), the following article is now online at AMG:

Abstract: “Emergence” – the notion of novel, unpredictable and irreducible properties developing out of complex organisational entities – is itself a complex, multi-dimensional concept. To date there is no single, generally agreed upon “theory of emergence”, but instead a number of different approaches and perspectives. Neither is there a common conceptual or meta-theoretical framework by which to systematically identify, exemplify and compare different “theories”. Building upon earlier work done by sociologist Kenneth Bailey, this article presents a method for creating such a framework, and outlines the conditions for a collaborative effort in order to carry out such a task. A brief historical and theoretical background is given both to the concept of “emergence” and to the non-quantified modelling method General Morphological Analysis (GMA).
