Abstract
In this paper we describe how generalized goal programming problems can be solved using our Visual Interactive Approach (Korhonen and Laakso, 1986). The method enables the decision maker to evaluate attainable solutions corresponding to his aspiration levels using computer graphics. Goals are divided into flexible and inflexible goals. This classification can be altered during the interactive process. If the problem is entirely linear, the approach can be implemented using any standard linear optimization package with a parametric optimization routine. In addition, a graphical display device is required.
