Fuzzy systems and soft O.R

Proposes a confluence between soft OR and soft computing methods, by means of an application of fuzzy logic ideas to robustness analysis. Both methods try to add flexibility to proposed solutions, of real world problems, although insofar as their application contexts is concerned, they have been quite apart. So it is only natural to bring them together in what could be called a "fuzzification" of robustness analysis. A first step in that direction is attempted in the paper.
