Abstract
The purpose of this research is re-implementation of fuzzy library with programming language Go and extending for parallel programming. Go is new system programming language. Furthermore, an excitable binary file like C language can output, and a parallel programming and the garbage collection are supported. The research of 1995 years defined Fuzzy Description Language(FDL) which provide simple syntax of fuzzy inference. After it is translated to C program code which call the fuzzy library, it is compiled to a executable binary file. But this fuzzy library not enough supports recent programming. Recently computers speed up by multi-core CPU, therefor fuzzy library should support parallel programming. Thus we implement the fuzzy library in Go.
