In business and non-business organizations, there are many management decision problems where decision makers consider multiple fuzzy goals. For such problems, a mathematical approach called ‘fuzzy goal programming’ has been developed. In this paper, fuzzy goal programming is illustrated on goal space with the concept of ‘aspiration vector’ and indifference curve. After five membership functions investigated by many researchers are classified into two classes, new membership functions are proposed. Finally, some simple example problems with two goals and two variables are demonstrated. [In Japanese.]
