On solving a multiobjective fixed charge problem with imprecise fractional objectives
Fixed charge problem. Multiple fractional objective functions. Imprecise nature of objective functions, i.e. fuzzy coefficients and fuzzy fixed charges. Systematically enumerating the extreme points of feasible region. Ranking function employed to deal with the fuzziness. Set of efficient solutions obtained. Set of nondominated criterion values of a fuzzy nature can also be obtained. Numerical example provided to illustrate the algorithm.
