英文摘要：

A novel fuzzy reasoning method named fuzzy reasoning method by optimizing the similarity of truth-tables （OS method for short） was proposed and discussed. Firstly,the principle of the OS method was given according to the analysis of the basic idea of the OS method. Secondly,the relationship between the OS method and CRI method was discussed. Thirdly,the OS methods with max-min similarity measure and some common implications were investigated. Finally,numerical examples were given to compare the inference abilities of the OS method,CRI method and triple I method. The theoretical analysis and numerical examples showed that the OS method had a good logical foundation and good inference ability.
