摘要: This article presents a fuzzy goal programming (FGP) procedure for solving quadratic bilevel problems (QBLPP). In the proposed approach, membership functions defined objective goals of decision makers (DM) at both levels are developed first. Then, model is formulated by using notion distance function minimizing degree regret to satisfaction DMs. At first phase solution process, transformed into an equivalent nonlinear (NLGP) maximize value each on extent possible basis their priorities in context. second phase, concept linear approximation technique introduced measuring DMs arriving compromised regarding optimality two different sets variables controlled separately them. A numerical example provided illustrate approach. © 2003 Wiley Periodicals, Inc.
