interdisciplinary content. The modern Ukrainian environment, through which the legal values of
European (Euro-Atlantic) and universal civilizations - principles, norms, institutions, sources of
law, legal procedures, etc. - are “refracted” (“passed through”), is quite heterogeneous and
contradictory, and this cannot but affect the peculiarities of Ukrainian law.
These problems include, in particular, the absence, unlike in many European countries, of

In this paper, a novel approach for solving fuzzy goal programming is proposed.  This approach utilizes the weighted maxmin and weighted minmax methods simultaneously.  Relative weight is assigned to each fuzzy goal according to the preference of the decision maker.  A model for each of the two methods is separately stated; hence the two models are merged into one.  Moreover, the lexicographic maximization technique is applied to guarantee efficient solutions.  Therefore, the proposed approach allows the decision maker to compromise between the two methods.  Furthermore, the proposed approa
