CREDO: A military decision-support system based on credal networks

Abstract

Abstract—A software tool especially designed for military domains to create and query decision-support systems is presented. Credal networks, which are Bayesian networks whose parameters have the freedom to vary in convex sets, are used to model the relations among the system variables. A novel elicitation procedure of these sets, which allows the military experts to report their knowledge by purely qualitative judgements, is proposed. Two high-level fusion procedures to cope with multiple experts in this framework are also derived. All these features are supported by the software and demonstrated in an application to space security tested during the last NATO multinational experiment. from qualitative judgements (Sect. V). These ideas have been implemented in a Java software tool, called CREDO, as part of a project granted by Armasuisse (the Swiss federal body for the procurement of technologically complex systems and equipment, security-related technologies and quality management). Some implementation details about the architecture and the interface are provided (Sect. VI). Finally, as a demonstrative example, we present a DSS for space security based on a credal network, which have been developed and tested with CREDO during the last NATO multinational experiment (Sect. VII). I.
