چکیده
This paper presents a fuzzy goal programming (GP) procedure for solving a multiobjective linear plus linear fractional programming problem. In the proposed approach GP model for achievement of the highest membership value of each of fuzzy goal defined for the linear plus linear fractional objectives is formulated. In the solution process, the method of variable change on the underand overdeviational variables of the membership goals associated with the fuzzy goals of the model is introduced to solve the problem efficiently by using goal programming(GP) methodology and method of approximation(MAP). A numerical examples is given to illustrate this algorithm. The examples is solved by optimization software TORA@ 2.0 version, 2006. Key–Words: Multiobjective Programming, Fractional programming, Fuzzy multiobjective linear fractional programming, Goal programming, Fuzzy goal programming.

Linear plus fractional multiobjective programming problem with homogeneous constraints using fuzzy approach
We develop an algorithm for the solution of multiobjective linear plus fractional programming problem (MOL+FPP) when some of the constraints are homogeneous in nature. Using homogeneous constraints, first we construct a transformation matrix T which transforms the given problem into another MOL+FPP with fewer constraints. Then, a relationship between these two problems, ensuring that the solu...
