Application of Restriction Coefficient in Optimal Comparison of Triangle Fuzzy Numbers

In the paper, in view of the fact that triangle fuzzy numbers´ comparison has importance in actual project and more or less flaw in former comparative method, the necessity of improvement is proposed. Because the restriction coefficient combines fuzzy average value, fuzzy standard dispersion and fuzzy information content and other merits, it is introduced into triangle fuzzy numbers´ comparison in order to improve its flaw and shortage in the comparison and make it more perfect. It explains its merit and the validity by examples´ analysis.
