An ideal tool for developing advanced model-based decision support systems

HUGIN is a software package for developing and deploying decision support systems for reasoning and decision making under uncertainty. HUGIN software is based on Bayesian network and influence diagram technology. Bayesian networks and influence diagrams are widely used for supporting decision making under uncertainty. A Bayesian network or influence diagram is a graphical modeling tool for knowledge representation and inference under uncertainty. The knowledge base can integrate information from a range of different sources including literature, subjective estimates, and historical data. The knowledge base describes dependence and independence relations between a set of variables where the dependence relations are quantified using probability distributions. The combination of a knowledge base and an efficient inference engine makes it possible to support reasoning and decision making under uncertainty in even highly complex domains.

HUGIN software tools

The HUGIN software package consists of the HUGIN Decision Engine (HDE), a Graphical User Interface (GUI) and Application Program Interfaces (APIs) for the easy integration of HUGIN into applications.

The HUGIN Decision Engine utilizes breakthrough algorithms discovered by a Danish research team and is recognized as one of the most efficient and robust inference engines on the market. Other HDE implementations utilizing Bayesian networks and influence diagrams include object-oriented modeling, learning from data with both continuous and discrete variables, value of information analysis, sensitivity analysis and data conflict analysis. The HDE also supports function nodes for post-propagation calculations as well as easy web-deployment.
