A Statistical Approach to Complex Multi-Criteria Decisions, in, D. Ruan (Ed.) Computational Intelligence in Complex Decision Systems, Chapter 6 Vrije Universiteit Brussel
Complex decisions problems have most of the time multiple-criteria dimensions. Many existing multiple-criteria decision tools are however plagued with difficulties due to uncertainties on data and preference weights, multiple decision-makers, correlations between criteria, etc., and last but not least, undesirable properties, like rank reversal. The chapter investigates an original approach using the correlations between criteria, as a measure ...
No genetics without epigenetics? No biology without systems biology? On the meaning of a relational viewpoint in a complex account of living systems Universiteit Gent
Complex Adaptive Systems Thinking Approach to IT Investment Universiteit Hasselt
The main research idea of this thesis is to develop a strategic IT investment framework using primarily military concepts as a basis. On the one side we discuss the most influencing military thinkers in Belgian Defense Karl von Clausewitz and in the USA John Boyd (together with Karl von Clausewitz). On the other hand, the causes and consequences of a fairly new concept Network-Centric Warfare (NCW) are investigated because NCW has dramatically ...
Social translucence as a transition-inducing mechanism in complex socio-ecological systems Vrije Universiteit Brussel
As well-known, the interplay between human beings and their environment is complex and non-linear, with changes to initial conditions and local behaviors often being associated with the emergence of dramatically different global (macroscopic) changes. This paper discusses the problem of inducing significant behavioral changes in ecologically biocomplex systems. The role of social translucence in this context is hypothesized and reasoned upon. ...
Healthcare teams as complex adaptive systems : understanding team behaviour through team members’ perception of interpersonal interaction Universiteit Gent KU Leuven
Scalable compact models for fast design optimization of complex electromagnetic systems Vrije Universiteit Brussel Universiteit Gent
We propose a new parametric macromodeling technique for complex electromagnetic (EM) systems described by scattering parameters, which are parameterized by multiple design variables such as layout or substrate feature. The proposed technique is based on an efficient and reliable combination of rational identification, a procedure to find scaling and frequency shifting system coefficients, and positive interpolation schemes. Parametric ...
Visualising multi-criteria weight elicitation by multiple stakeholders in complex decision systems Vrije Universiteit Brussel
An efficient and transparent weight elicitation technique is proposed for inclusion into the adaptive, systemic, control and multi-criteria-based methodology, in short ASCM, the purpose of which is piloting in real time complex systems by combining system dynamics (SD) and multi-criteria decision analysis (MCDA). Piloting policies are established and revised on a regular basis and/or constant real-time observation by means of SD simulations; at ...
