Use of Type-2 Fuzzy Sets for Military Value of Information Decision Support

Abstract

Fuzzy systems are known to be excellent for reasoning where information is uncertain, incomplete, imprecise, and/or vague. Over the past several years, work has been done to prototype an automated value of information (VoI) decision support tool for military intelligence analysts. The system was constructed using the type-1 fuzzy sets. Recently, the use of type-2 fuzzy sets has been proffered as an alternative to account for the differing opinions expressed by the experts during the knowledge elicitation process. Compounding this challenge for the military is the fact that military science is as much an art as it is a science. The work described in this paper focuses on the investigation with respect to transitioning to type-2 fuzzy sets.
