	abstract = "We will use the notion of neighbourhood-spaces as the ranges of arbitrary hazy structures imposed on the set of truth values in a multiple-valued logic instead of a point-wise truth values. In light of this consideration, we can characterize and modify the indistinguishable formulas of the propositional or first order multiple-valued logics. Thus, any problem in any ordinary <I>m</I>-valued logic, for instance the problem of realizability of a formula &#060;$&#062;varphi&#060;$&#062;, can be reduced to that of a corresponding problem in <I>n</I>-valued logic where <I>m</I> might be a finite or transfinite ordinal number and &#060;$&#062;nle m&#060;$&#062;, that is to say that we can reduce the denumerable or even continuum valued logics to a finite <I>n</I>-valued logic such as Lukasiewicz 3-valued logic. In the final part of the paper we are using neighbourhood (nbd.) system or hazy structures for necessities and possibilities as relevant examples.",
