The online interface below implements a multi-criteria decision analysis (MCDA) in an object-oriented Bayesian network (OOBN) with scaling and weight nodes specifying an additive multi-attribute value function. The OOBN is used to integrate impacts generated by quantitative simulation models of hydropower revenues and Atlantic salmon smolt production, with qualitative expert modeling of mesohabitat fishability and riverscape aesthetics. See Barton et al. (under review) for further documentation[Barton et al, 2018]. The tabs below represent the node monitors in the OOBN - green bars represent the probability distribution, while orange bars represent marginal utilities of each node state (in HUGIN software the utilities are represented by the bars on the right hand side of the monitors in Figure 1). Separate tabs provide a dashboard of node monitors for the Fishability (Figure 2) and Riverscape aesthetics (Figure 3) sub-networks in the OOBN.
Below are some HUGIN widgets for interacting with the model. This interface has been developed using the HUGIN Web Service API ([Madsen et al, 2013]).
