Aggregation of Fuzzy Systems in Multi-level Decisions

Abstract

Although the various approaches proposed for fuzzy multi-level programming in the previous chapter are very useful, it is only a start in this fruitful direction. Further developments are needed to consider other aspects and thus to make the actual solution process more practical in the sense of solving more realistic problems with reduced computation. Two of the most important aspects which need to be considered are the problem of aggregation of the fuzzy representation and the representation of systems whose description is vague and not well defined.
