Abstract
It should be important to represent a fuzzy graph as an approximate graph and clarify its relational structure. We propose a methodology to solve this problem using a personal computer, which we have developed. The system could analyze the problem easily, speedly and exactly. But the system had several points to be desired. So, we have partially some performances of it, and inplemented on a personal computer. In this article, we describe the functions, performances and a case study.
