Floating ideas—An experiment in enhancing hypergames with maps

Within the OR community, an increasing emphasis is being placed on developing approaches to tackle complex, ‘messy’ decision problems. The work described in this paper arose out of the premise that it would be desirable to integrate ideas from a number of different approaches of this type. Specifically, the paper describes one experimental attempt to link methods for modelling conflict situations (the analysis of options and hypergames) with the cognitive mapping approach to eliciting subjective data. Taking a personally-owned decision problem, mapping was used to enrich the game-based approaches by providing a way of documenting the argumentation underlying the models used. Though difficult to generalise from, the experiment not only suggested that such an extension is likely to be an improvement, but also highlighted some deficiencies in the existing versions of the game-based approaches themselves.
