USO DE PLANILHA ELETR NICA PARA IMPLEMENTA O DA LóGICA NEBULOSA EM PROBLEMAS DE FORMULA O LINEAR MULTIOBJETIVO

One of the most delicate aspects in applying Multiple Objective Linear Programming (MOLP)resides on the objective function (OF) formulation. An adequate choice is crucial for the success of aMathematical Programming (MP) model. Romero (2004) states that the results coming from using PMand MOLP are strongly affected by the function type that is chosen. This document presents a proposalof a new interactive algorithm for linear multiobjective formulation that is an extension of the methodintroduced in (Gomes and Chaves, 2004, 2005 & 2006). Here we intend through the use of a relevancyfunction to promote an interpretation of the FO that will allow increasing the specter of options of thedecision maker in the sensitivity analysis. With this we focus to skirt eventual distortions that can happenin problems where, for example, the values assumed for the FO’s are very discrepant, or in situations wherethe weighed addition of the maximum values can privilege a function in relation to another one. Suchsituations are likely to occur in classic formulations of MOLP.
