Fuzzy comprehensive evaluation is widely used in evaluation. Based on thorough analysis of the FCE model, this paper puts forward the design idea of FCE general software, develops a stand-alone prototype, which can be used to give the solution of those problems whose condition is undetermined, boundary is not clear and difficult to describe quantitatively. Finally, it takes economic benefits evaluation on enterprise quality as an example, using the software to evaluate. The results prove the effectiveness and practicality of FCE software, provide a reference for the design and development of higher class evaluation software.
