Interactive fuzzy programming approach to Bi-level quadratic fractional programming problems 总被引:1,自引:0,他引:1
In this paper we propose an interactive fuzzy programming method for obtaining a satisfactory solution to a “bi-level quadratic
fractional programming problem” with two decision makers (DMs) interacting with their optimal solutions. After determining
the fuzzy goals of the DMs at both levels, a satisfactory solution is efficiently derived by updating the satisfactory level
of the DM at the upper level with consideration of overall satisfactory balance between both levels. Optimal solutions to
the formulated programming problems are obtained by combined use of some of the proper methods. Theoretical results are illustrated
with the help of a numerical example. 相似文献
