Prof. Jon Garibaldi is giving a keynote presentation at CEEC 2016, the 8th Computer Science & Electronic Engineering Conference taking place at University of Essex, UK, on Friday 30th September. Copies of his slides will be posted here soon after the talk.
Bob John has just had an article accepted in the International Journal of Approximate Reasoning.
This paper concerns itself with decision making under uncertainty and the
consideration of risk. Type-1 fuzzy logic by its (essentially) crisp nature
is limited in modelling decision making as there is no uncertainty in the
membership function. We are interested in the role that interval type-2 fuzzy
sets might play in enhancing decision making. Previous work by Bellman and
Zadeh considered decision making to be based on goals and constraint. They
deployed type-1 fuzzy sets. This paper extends this notion to interval type-2
fuzzy sets and presents a new approach to using interval type-2 fuzzy sets
in a decision making situation taking into account the risk associated with
the decision making. The explicit consideration of risk levels increases the
solution space of the decision process and thus enables better decisions. We
explain the new approach and provide two examples to show how this new
