Aggregation of fuzzy values in linear programming problems

WOS: 000188783100001The problem of aggregation of the fuzzy values of objective functions and constraints in fuzzy linear programming problems is considered. Because the type of aggregation applied is additive, the fuzzy problem may be represented in the form of an ordinary linear programing problem without complication of structure. A method of increasing the degree of unfuzziness of the solution by varying the weighting coefficients of the level sets is proposed
