From the CDM outputs, propositional networks were constructed for each incident phase.
The propositional networks are presented in Figure 3-5 to Figure 3-9. Propositional
networks consist of a set of nodes that represent sources of information, agents, and
objects etc. that are linked through specific causal paths. From this network, it is possible
to identify required information and possible options relevant to this incident. The
concept behind using a propositional network in this manner is that it represents the
‘ideal’ collection of knowledge for the scenario. As the incident unfolds, so participants
will have access to more of this knowledge (either through communication with other
agents or through recognising changes in the incident status). Consequently, within this
propositional network, Situation Awareness can be represented as the change in
weighting of links. Propositional networks were developed for the overall scenario and
also the incident phases identified during the CDM analysis. The propositional networks
indicate which of the knowledge objects are active (i.e. agents are using them) during
each incident phase. The light blue nodes in the propositional networks represent
unactivated knowledge objects (i.e. knowledge is available but is not required nor is it
being used). The red nodes represent active (or currently being used) knowledge objects.
